Authors:Jianmin Guan, Ping Xiang, William M. Land, Xiaofen D. Hamilton Abstract: Perceptual and Motor Skills, Ahead of Print. We examined gender and grade differences in the relationship between students’ perceived competence, their enjoyment of physical education (PE), and their PA persistence on the frequency of their physical activity (PA). We also used structural equation modeling to assess the direct, indirect, and total effects of perceived competence and PE enjoyment on PA frequency through the mediator of PA persistence. Participants were 223 middle school students (115 boys, 108 girls) in grades 7 and 8. We found that, regardless of grade level, girls had lower perceived competence and PE enjoyment than boys. Both perceived competence and PE enjoyment had significant direct and positive connections to persistence, but they had no significant indirect effects on PA frequency through the mediator of persistence. These findings highlight the need for physical educators to be aware of gender differences in perceived competence and PE enjoyment, and the important roles these factors have in enhancing students’ PA participation.

In this study, we aimed to investigate the effects of warm-up music preference and loudness on physical performance, perceived exertion (RPE), and enjoyment in young taekwondo athletes. In a crossover counterbalanced design, 20 taekwondo athletes (10 male, 10 female) performed a battery of physical tasks specific to taekwondo under the following five conditions: (a) No music (NM), (b) Preferred music-Soft (60 dB; PMS), (c) Preferred music-Loud (80 dB; PML), (d) Non-preferred music-Soft (60 dB; NPMS), and (e) Non-preferred music-Loud (80 dB; NPML). On each lab visit, participants completed a taekwondo-specific agility test (TSAT), a10-second kick test (KSKT-10s) and a multiple frequency speed of kick tests (FSKT) within each music condition. Pre-exercise enjoyment was assessed using the Physical Activity Enjoyment Scale (PACES) after the warm-up, while we obtained RPE scores after each test. The PML condition resulted in significantly better agility test times on the TSAT compared to PMS (p < .001), and NPML (p < .001). Furthermore, PML led to a greater number of total kicks during the FSKT-10s test compared to the PMS (p < .001), and NPML (p < .001) conditions. The decrement index on the FSKT was lower in PML than in PMS and NPML conditions (p < .001). For RPE, values were significantly lower with preferred than non-preferred music (p < .001). These findings lend support to ergogenic benefits of listening to PML prior to taekwondo physical tasks, with important implications for enhancing taekwondo training and performance.

Authors:Nicholas P. Cherup, Linda E. Robayo, Roberta Vastano, Loriann Fleming, Bonnie E. Levin, Eva Widerström-Noga Abstract: Perceptual and Motor Skills, Ahead of Print. Cognitive dysfunction, pain, and psychological morbidity all present unique challenges to those living with traumatic brain injury (TBI). In this study we examined (a) the impact of pain across domains of attention, memory, and executive function, and (b) the relationships between pain and depression, anxiety, and post-traumatic stress disorder (PTSD) in persons with chronic TBI. Our sample included 86 participants with a TBI and chronic pain (n = 26), patients with TBI and no chronic pain (n = 23), and a pain-free control group without TBI (n = 37). Participants visited the laboratory and completed a comprehensive battery of neuropsychological tests as part of a structured interview. Multivariate analysis of covariance using education as a covariate, failed to detect a significant group difference for neuropsychological composite scores of attention, memory, and executive function (p = .165). A follow-up analysis using multiple one-way analysis of variance (ANOVA) was conducted for individual measures of executive function. Post-hoc testing indicated that those in both TBI groups preformed significantly worse on measures of semantic fluency when compared to controls (p < 0.001, ηρ2 = .16). Additionally, multiple ANOVAs indicated that those with TBI and pain scored significantly worse across all psychological assessments (p < .001). We also found significant associations between measures of pain and most psychological symptoms. A follow-up stepwise linear regression among those in the TBI pain group indicated that post concussive complaints, pain severity, and neuropathic pain symptoms differentially contributed to symptoms of depression, anxiety, and PTSD. These findings suggest deficits in verbal fluency among those living with chronic TBI, with results also reinforcing the multidimensional nature of pain and its psychological significance in this population.

Authors:Evrim Gökçe, Neslişah Gün Abstract: Perceptual and Motor Skills, Ahead of Print. Exercise has been shown repeatedly to improve cognitive functions. Many investigators have reported that peripheral signal molecules play an important role in regulating exercise-induced cognitive improvement. In this review we aimed to evaluate and clarify the literature to date that has focused on the relationship between Cathepsin B, cognitive functions, and exercise. We conducted a systematic review of the following databases from their inception until 10 April 2022: Pubmed, Web of Science, Scopus, Cochrane Library, Physiotherapy Evidence Database. The search strategy was comprised of (“cathepsin b”) AND (exercise OR “physical activity”) AND (cognit*). We followed three different quality appraisal tools to ensure the quality of the included studies. Eight studies assessing the effects of exercise on peripheral Cathepsin B levels and cognitive outcomes were included. Half of these studies indicated that exercise increased peripheral Cathepsin B levels and improved cognitive function. Further carefully designed studies focusing on the effects of exercise on peripheral Cathepsin B levels and cognitive performance are needed to better comprehend the underlying mechanisms of these relationships.

Authors:Jon Sundan, Monika Haga, Håvard Lorås Abstract: Perceptual and Motor Skills, Ahead of Print. The purpose of this study was to design and develop the Swimming Competence Assessment Scale (SCAS) to measure children’s aquatic skills as they align with the physical education curriculum for Norwegian primary schools. We conducted a three-round modified Delphi study involving 22 national experts in the aquatic profession. Experts reached consensus on scale items within an observation form and coding sheet based on a swimming proficiency test for measuring six aquatic skills: water entry, frontstroke swimming, surface dive, float/rest, backstroke swimming and water exit. Independent experts obtained high agreement (scale level: 88%, item level: 80–93%) on the relevance, representativeness, and clarity of the scale. Current results suggest that the SCAS is a valid instrument for researchers and practitioners to observe and record children’s aquatic proficiency for the purpose of screening and developing aquatic education.

Authors:Alysson Enes, Gustavo Oneda, Danilo Fonseca Leonel, Renan Alberton Ramos, Vinnicius C. Kvas-Cabral, Mauro F. Bernardo, Guillermo Escalante, Tácito P. Souza-Junior Abstract: Perceptual and Motor Skills, Ahead of Print. We compared the effects of resistance training (ResisT) to pyramidal and traditional weightlifting sets on men’s psychophysiological responses. In a randomized crossover design, 24 resistance-trained males performed drop-set, descending pyramid, and traditional ResisT in the barbell back squat, 45° leg press, and seated knee extension. We assessed participants’ rating of perceived exertion (RPE) and feelings of pleasure/displeasure (FPD) at the end of each set and at 10, 15, 20, and 30 minutes post-session. No differences were detected across ResisT Methods in total training volume (p = 0.180). Post hoc comparisons revealed that drop-set training elicited higher RPE (M 8.8 SD 0.7 arbitrary units) and lower FPD (M −1.4 SD 1.5 arbitrary units) values compared to descending pyramid (M Set RPE 8.0 SD 0.9 arbitrary units and M Set FPD 0.4 SD 1.6 arbitrary units) and traditional set (M Set RPE 7.5 SD 1.1 arbitrary units and M Set FPD 1.3 SD 1.2 arbitrary units) schemes (p < 0.05). In addition, drop-set training elicited higher session RPE (M 8.1 SD 0.8 arbitrary units) and lower session FPD (M 0.2 SD 1.4 arbitrary units) values than descending pyramid and traditional ResisT (p < 0.001). Similarly, descending pyramid training elicited higher session RPE (M 6.6 SD 0.9 arbitrary units) and lower session FPD (M 1.2 SD 1.4 arbitrary units) than traditional set (M Session RPE 5.9 SD 0.8 arbitrary units and M Session FPD 1.5 SD 1.2 arbitrary units) training (p = 0.015). No differences were found in the temporality of post-session metrics, suggesting that testing 10 and 15 minutes post-ResisT was sufficient to assess session RPE (p = 0.480) and session FPD (p = 0.855), respectively. In conclusion, even with similar total training volume, drop-set training elicited more pronounced psychophysiological responses than either pyramidal or traditional ResisT in resistance-trained males.

Authors:Fatmir Misimi, Tajna Kajtna, Igor Štirn, Dajana Zoretić, Samir Misimi, Jernej Kapus Abstract: Perceptual and Motor Skills, Ahead of Print. In recent research, we found that the use of goggles and snorkel benefited non-swimmers with fear of water in a learn-to-swim program. Our purpose in this study was to examine the effects of using goggles and snorkel during a learn-to-swim program on the aquatic skills of young non-swimmers without fear of water. We modelled this research on our prior study. Following informed parental consent, 40 children (aged 10–11 years) were randomly divided into two groups: one that used goggles and snorkel (GS) and one that did not (NGS). After 4 weeks (five sessions per week) of learn-to-swim intervention, both groups improved aquatic skills such that the only group differences were for the blowing bubbles test, for which the learn-to-swim program resulted in smaller gains for the GS than the NGS group. Thus, the use (vs. non-use) of goggles and snorkels during the learn-to-swim program had no significant effect on most aquatic skills of young non-swimmers without fear of water. The only exception was a significant finding of reduced improvement in blowing bubbles in the goggles and snorkels group when compared to the no goggles and snorkel group. Together with past findings these results highlight important learn-to-swim differences between young non-swimmers with and without fear of water.

Authors:Asif Ullah, Yifan Liu, You Wang, Han Gao, Zhiyuan Luo, Guang Li Abstract: Perceptual and Motor Skills, Ahead of Print. Males and females respond differently at the muscular level to various tastes and show varied responses when eating different foods. In this study, we used surface electromyography (sEMG) as a novel approach to examine gender differences in taste sensations. We collected sEMG data from 30 participants (15 males, 15 females) over various sessions for six taste states: a no-stimulation physiological state, sweet, sour, salty, bitter, and umami. We applied a Fast Fourier Transformation to the sEMG-filtered data and used a two-sample t-test algorithm to analyze and evaluate the resulting frequency spectrum. Our results showed that the female participants had more sEMG channels with low frequencies and fewer channels with high frequencies than the male participants during all taste states except the bitter taste sensation, meaning that for most sensations, the female participants had better tactile and fewer gustatory responses than the male participants. The female participants responded better to gustatory and tactile perceptions during bitter tasting because they had more channels throughout the frequency distribution. Moreover, the facial muscles of the female participants twitched with low frequencies, while the facial muscles of the male participants twitched with high frequencies for all taste states except the bitter sensation, for which the female facial muscles twitched throughout the range of the frequency distribution. This gender-dependent variation in sEMG frequency distribution provides new evidence of differentiated taste sensations between males and females.

Authors:Po-Sheng Huang, Shih-Jun Chung, Cheng-Hong Liu, Pei-Zhen Chen Abstract: Perceptual and Motor Skills, Ahead of Print. Scholars refer to individuals who have been immersed in digital environments and who make easy use of digital languages to interact with the world as “digital natives,” and Teo proposed four attributes of digital natives to illustrate their behavioral tendencies. We aimed to expand Teo’s framework and to develop and validate the Scale of Digital Native Attributes (SDNA) for measuring cognitive and social interactive attributes of digital natives. Based on pre-test results, we retained 10 attributes and 37 SDNA items, with 3–4 items in each sub-dimension. We then recruited 887 Taiwanese undergraduates as respondents and conducted confirmatory factor analysis to establish construct validity. Moreover, the SDNA correlated with several other related measurements to demonstrate satisfactory criterion-related validity. Internal consistency was evaluated by McDonald’s Omega (ω) and Cronbach’s α coefficient, showing satisfactory reliability. This preliminary tool is now ready for cross validation and temporal reliability testing in further research.

Authors:Eylul Pinar Kisa, Begum Kara Kaya Abstract: Perceptual and Motor Skills, Ahead of Print. In overhead shooting athletes may have increased activity of the upper trapezius and inhibition of other shoulder muscles active during upper extremity elevation. In this study, we aimed to increase target retention and shoulder proprioception sense accuracy by taping in a way that would activate the lower trapezius muscle in elite adolescent archers. Our participants were 43 elite young athletes, aged 11–14 years, from the Archers Foundation Sports Club. We gathered athletes' sociodemographic information (age, height, weight, gender, the time they were engaged in archery, and other sports they were involved in), and we assessed their posture via the New York Posture Scale (NYPS) before taping. We evaluated them for the presence of scapular asymmetry using the Lateral Scapular Slide Test (LSST) and assessed their proprioception with the active displacement test and their target-reaching performances with the Archery Shooting Score (ASS). Since testing and scoring with the ASS is different for 11–12 and 13–14 age groups, we divided this sample into two different age groups for all analyses. There were significant changes in ASS and proprioception in both age groups, with medium to large effect sizes. There were between intragroup pre- and post-taping changes in classification according to the presence of scapular asymmetry, and there were significant changes in the archery shooting score and proprioception in both groups, with medium to large effect sizes (p < 0.05). Thus, taping applied to the lower part of the trapezius had a large to medium effect on proprioception and shooting accuracy improvement in these young archers.

Authors:Julia Sjögren, Per-Anders Fransson, Mitesh Patel, Christoffer Lundén Blom, Rolf Johansson, Måns Magnusson, Fredrik Tjernström Abstract: Perceptual and Motor Skills, Ahead of Print. The human vestibulo-ocular reflex (VOR) leads to maintenance of the acuity of an image on the retina and contributes to the perception of orientation during high acceleration head movements. Our objective was to determine whether vision affects the horizontal VOR by assessing and comparing the performance at the boundaries of contribution of: (a) unrestricted visual information and (b) no visual information. Understanding how the VOR performs under both lighted and unlighted conditions is of paramount importance to avoiding falls, perhaps particularly among the elderly. We tested 23 participants (M age = 35.3 years, standard error of mean (SEM) = 2.0 years). The participants were tested with the video Head Impulse Test (vHIT), EyeSeeCam from Interacoustics™, which assesses whether VOR is of the expected angular velocity compared to head movement angular velocity. The vHIT tests were performed under two conditions: (a) in a well-lit room and (b) in complete darkness. The VOR was analyzed by evaluating the gain (quotient between eye and head angular velocity) at 40, 60 and 80 ms time stamps after the start of head movement. Additionally, we calculated the approximate linear gain between 0-100 ms through regression. The gain decreased significantly faster across time stamps in complete darkness (p < .001), by 10% in darkness compared with a 2% decrease in light. In complete darkness, the VOR gain gradually declined, reaching a marked reduction at 80 ms by 10% (p < .001), at which the head velocities were 150°/second or faster. The approximate linear gain value was not significantly different in complete darkness and in light. These findings suggest that information from the visual system can modulate the high velocity VOR. Subsequently, fast head turns might cause postural imbalance and momentary disorientation in poor light in people with reduced sensory discrimination or motor control, like the elderly.

Authors:Vincent Huard Pelletier, Jean Lemoyne Abstract: Perceptual and Motor Skills, Ahead of Print. Perceived competence plays a crucial role in establishing environments favorable to individual development in youth sport. As most assessment tools of perceived competence are not sport-specific, they have limited usefulness for sport practitioners and researchers. This study had two-fold aims: (i) to develop a perceived competence assessment tool specific to ice hockey; and (ii) to examine its factorial structure and internal consistency. We first developed an initial 29-item version of this ice hockey competence self-report scale, using a group of ice hockey stakeholders and sports science experts to develop the items and a pilot sample of 42 hockey players to confirm test-retest reliability. Finally, we validated the scale among a cohort of 770 adolescent ice hockey players (M age = 14.78, SD = 1.60 years). Results from exploratory factor analysis (EFA) revealed that perceived competence in ice hockey was defined by six dimensions, with rejection of seven items. Confirmatory factor analysis (CFA) suggested that the 6-factor first order model was the best fit with the conceptualization of perceived competence in ice hockey (CFI = 0.938, RMSEA = 0.044). The final, 22-item questionnaire now provides a reliable and valid measure of perceived competence in hockey for adolescent participants. It has promise for evaluating future interventions aiming to foster young athletes’ perceived confidence through sport.

Authors:Chia-Hao Yang, Fang-Ming Hwang, Bo-Chen Lin, Chia-Ming Chang Abstract: Perceptual and Motor Skills, Ahead of Print. This was a daily diary study using intensive longitudinal methods to evaluate the dynamic structure of relationships among employees’ self-reported health, psychological capital, daily workplace incivility, and daily emotional exhaustion. We recruited 200 participants working in health and fitness clubs for experience sampling and had them file the same questionnaires for 10 consecutive working days. A total of 179 participants (men = 57, 31.85%; women = 122, 68.15%) completed the questionnaires, with a response rate of 89.5%, leading to 1790 data points at the within-person level. We used a multilevel location-scale model of dynamic structural equation modeling (DSEM) for data analysis. We ran the model in Mplus software (version 8.4) and found an autoregressive ‘carry over’ relationship between the previous day’s emotional exhaustion changes on current emotional exhaustion changes ([math] = 0.067, CI = [0.003, 0.132]). Daily workplace incivility significantly and positively predicted daily emotional exhaustion at the within-person level ([math] = 0.953, CI = [0.465, 1.489]). Self-reported health was negatively associated with a person’s mean ratings of daily emotional exhaustion ([math] = −0.256, CI = [0.465, 1.489]) and moderated the strength of the workplace incivility effect on emotional exhaustion ([math] = −0.201, CI = [−0.292, −0.121]). Finally, psychological capital was negatively related to a person’s mean ratings of daily emotional exhaustion ([math] = −0.240, CI = [−0.377, −0.102]).

Authors:Lawrence C. McCloskey Abstract: Perceptual and Motor Skills, Ahead of Print. There is a rough consensus, after decades of research, that obstructive sleep apnea (OSA) is associated with mild cognitive impairments, especially in areas of executive functioning (EF), attention/working memory (A/WM), episodic memory (EM), and speed of speed of information processing (SIP). However, there is less consensus as to whether apnea severity matters for these impairments, which sleep variables matter most to which cognitive domains, whether common OSA comorbidities contribute to these determinations, or whether the apparent associations are really artifacts of these comorbidities. In this study, 40 participants with OSA submitted to polysomnography and to neuropsychological assessment with an expanded Halstead-Reitan Test Battery. Aggregates of tests to cover the four cognitive domains mentioned above were linearly regressed on the apnea-hypopnea index (AHI), the nadir of oxygen saturation (NOS), and hypertension and diabetes mellitus (scored present or absent). The AHI predicted both EF (p = .015; sr2 = .13) and A/WM (p = .023; sr2 = 11) in the primary analyses, and EM (p = .027; sr2 = .10) in the secondary analyses. Thus, AHI may affect EF, A/WM and perhaps EM beyond NOS and beyond two of OSA’s most common comorbidities. Implications of these findings are discussed here.

Authors:Jacob F. Remmert, Kelly R. Laurson, Michael C. Zourdos Abstract: Perceptual and Motor Skills, Ahead of Print. We assessed the accuracy of intraset repetitions in reserve (RIR) predictions on single-joint machine-based movements of trained and untrained men and women. Participants were 27 men (M age = 22, SE = 0.6 years; M weight = 90.8, SE = 4.0 kg; M height = 182.3, SE = 1.4 cm; M training experience = 66, SE = 9 months) and 31 women (M age = 20, SE = 0.4 years; M weight = 67.8, SE = 2.3 kg; M height = 167.6, SE = 1.1 cm; M training experience = 22, SE = 4 months). In one session, participants performed a five-repetition maximum (5RM) test on biceps curl, triceps pushdown, and seated row exercises; we then estimated one repetition maximum (1RM). Participants then performed four sets of each exercise, in a randomized order, to the point of momentary muscular failure at 72.5% of 1RM. During each set, participants indicated when they first perceived 5RIR and then predicted RIR on every repetition thereafter until failure. The difference between actual repetitions performed and predicted repetitions at each intraset prediction was determined to be the RIR difference (RIRDIFF). A 3-way repeated measures ANCOVA found that a 3-way interaction was not statistically significant (p = 0.435) and no covariates of sex (p = 0.917), training experience (p = 0.462) nor experience rating RIR significantly affected RIRDIFF (p = 0.462–0.917). There were significant main effects for the proximity to failure of the prediction and the set number (p < 0.01) but not for exercise (p = 0.688). Thus, intraset RIR predictions were more accurate when closer to failure and in later sets, but sex, training experience, and experience rating RIR did not significantly influence RIR prediction accuracy on machine-based single-joint exercises.

Authors:Rodolfo A. Dellagrana, Renan F. H. Nunes, Rodrigo L. P. Silva Abstract: Perceptual and Motor Skills, Ahead of Print. Our aims in the present study were to analyze home advantage (HA) and number of goals scored in consideration of the presence or absence of crowd support and the influence of team quality during the last 11 seasons of the Brazilian Soccer League first division. We analyzed data from 4162 matches played in the Brazilian Soccer League in seasons 2012–2022 (3563 matches with an audience and 599 matches without an audience). We calculated HA by comparing the number of points won at home as a percentage of the total number of points gained, and we also recorded the number of goals scored by home and away teams. For analyses, we divided the teams based on home and away matches, with and without crowds, and we classified teams into three ability groups, based on the points scoring percentage of the team at the end of the season. There was a HA in all seasons analyzed (i.e., home teams won more than 50% of the total points won at home); but in matches in empty stadiums, the HA was reduced significantly, compared to matches with crowd support (66.6% with crowd vs. 57.2% without crowd, p < 0.05). The number of goals in all seasons was higher for home teams than for away teams; however, away teams scored more goals in empty stadiums than in stadiums with crowd support (p < 0.05). The HA was greater in matches with crowd support than in matches without crowd support (p < 0.01), independent of the team’s ability level; but, top teams scored more goals than weaker teams (p < 0.01). In conclusion, in the Brazilian Soccer League, the HA and number of goals scored were affected by the presence or absent of an audience in the stadiums. While top teams scored more goals than weaker teams, the HA was lower without than with crowds, independent of team quality.

Authors:Vivian de Oliveira, Lucas Savassi Figueiredo, Luiz Gustavo Teixeira Fabrício dos Santos, Rubens Venditti, Henrique de Oliveira Castro Abstract: Perceptual and Motor Skills, Ahead of Print. A Relative Age Effect (RAE), by which young athletes with birthdates early in a calendar year have experienced a team selection advantage that persists throughout their careers, has been found to be prevalent in many sports. However, this phenomenon has not been investigated in the Paralympic sports context. Thus, we aimed to investigate the prevalence of RAE among male and female Brazilian Paralympic swimmers. Data from 694 ranked athletes were collected from the 2021 Brazilian Paralympic Swimmers National rankings. Athletes’ birthdates were divided into four quarters (Q1, Q2, Q3, and Q4) according to their month of birth. Chi-Square (χ2) goodness-of-fit tests were used to compare the observed and expected distributions of athletes born in each quarter, based on sex (male and female), impairment type (physical, visual, and intellectual), and swim stroke competition (freestyle, medley, backstroke, butterfly, and breaststroke). The observed birthdates distributions were different from expected in males (χ2 = 11.647; p = 0.009) and females (χ2 = 8.899; p = 0.031), for athletes with physical impairments (χ2 = 10.443; p = 0.015); and for athletes who competed in freestyle (χ2 = 16.683; p = 0.001), medley (χ2 = 12.343; p = 0.006) and backstroke (χ2 = 8.025; p = 0.045) races. Even though our results demonstrated asymmetric distributions of Brazilian Paralympic swimmers’ birthdates in many of the analyses, we could not establish the classical prevalence of athletes born at the beginning of the year that defines RAE. Therefore, the selection process of Brazilian Paralympic swimmers does not seem to be influenced by the athletes’ time of birth.

Authors:David H. Fukuda, João Paulo Lopes-Silva, Monica Yuri Takito, Emerson Franchini Abstract: Perceptual and Motor Skills, Ahead of Print. This study was conducted to determine whether the relative age effect (RAE) is present in different age groups, weight categories, sexes, and across different time frames in international-level judo competition. A total of 9451 judo athletes competing at the Olympic Games and/or World Championships in the Cadet, Junior and/or Senior age groups between 1993 and 2020 were considered. Athletesʼ birthdate distributions were grouped in four quartiles (Q1: January-March; Q2: April-June; Q3: July-September; Q4: October-December) and compared to a day-corrected theoretical distribution using Chi-squared analysis. Poisson regression was also used to evaluate the ability to explain weekly birth count. RAE was more prevalent in males than females (p < .05), and for Cadets and Juniors compared to Seniors (p < .05). Heavyweight and middleweight categories presented RAEs in Senior and Junior males, while for females it was present in Cadet heavyweights (p < .05). RAE was more prevalent in recent years (2009–2021) for Senior male judo athletes (p < .05). Poisson analysis illustrated some nuanced information, including RAE detection during an earlier time frame, not readily apparent with the traditional analysis.

Authors:Aiqing Nie, Bingyan Guo Abstract: Perceptual and Motor Skills, Ahead of Print. Collaborative recall by groups of people can evoke both memory detriments (e.g., collaborative inhibition) and benefits (e.g., error pruning and post-collaborative memory benefit). Yet, it remains indeterminate whether these effects are due to the emotional valence of stimuli and/or the specific subtypes of episodic memory tested (i.e., item memory and source memory), and whether they are related to the research procedure of directed forgetting (DF). We introduced item-method DF into collaborative memory research using a turn-taking procedure. The to-be-recalled words were studied in different emotional valences and were followed by either an R or F cue, which, respectively, instructed participants to remember or forget the words presented. We conducted two recall sessions (Recall 1 and Recall 2) that included the two subtypes of episodic memory. Recall 1 was performed either individually or collaboratively, while Recall 2 was always performed individually. We observed three major findings: (a) a collaborative memory decrement - collaborative inhibition - was minimally affected in both item memory and source memory tasks by either the emotional valence of the stimuli or the DF cue; (b) a collaborative memory benefit - error pruning of item memory - persisted within both ongoing and post-collaboration, while error pruning of source memory only presented in ongoing collaboration, thus demonstrating the relevance of dual-process models that differentiate automatic familiarity and effortful recollection processes; and (c) there was no post-collaborative memory benefit, indicating the importance of the type of collaborative procedure. We discuss these results in terms of various theories, including the retrieval strategy disruption hypothesis (RSDH) which asserts that memory strategies tend to be disrupted in collaboration but are facilitated within post-collaboration. Also, we describe the implications of these results and directions for exploring other influential factors in future research.

Authors:Riller Silva Reverdito, Sofia Fonseca, Antonio Lopes, Karyna Aires, Luciano Santos Alves, Leilane Alves de Lima, Mayara de Almeida Tavares, Carlos Gonçalves Abstract: Perceptual and Motor Skills, Ahead of Print. Young people’s sources of satisfaction in sport are an important indicator of their long-term sport participation. Contextual factors and an individual’s internal dispositions act synergistically to determine a positive experience. We studied sources of sport satisfaction and perceived self-efficacy of 1,151 male and female youth athletes (M age = 14.72, SD = 1.56 years) in Brazil who were engaged in school state level competition. The participants responded to questionnaires on their sport satisfaction and perceived self-efficacy. We considered sex, training time, and last game results as independent variables in accessing participant differences in perceived satisfaction. We observed an increasing trend toward more significant satisfaction as sport experience increased. Perceived self-efficacy was a moderator for young participants’ self-reported positive experience in sports. Thus, in our offer of evidence on sources of satisfaction in sport and perceived self-efficacy among youth in competition, we found the extent of the sport experience and self-efficacy to be important factors in the developmental pathway.

Authors:Paulo Henrique Borges, Julio Cesar da Costa, Luiz Fernando. Ramos-Silva, Felipe A. Moura, Hélio Serassuelo Junior, Alexandre Moreira, Gibson Moreira. Praça, Enio Ricardo Vaz Ronque Abstract: Perceptual and Motor Skills, Ahead of Print. Prior research has suggested relevance to anthropometric variance of youth athletes at various stages of their maturation, and prior studies of youth players’ soccer skills have failed to consider their interdependent interactions during play. Accordingly, to address both of these separate research omissions, we aimed in this study to analyze the relationships between young (U-13 and U-15 groups) soccer players’ bone age and body size indicators and centrality measures of their pass interactions during small sided games. We included young 81 athletes (M age = 14.4, SD = 1.1 years) from whom we took anthropometric measurements of body mass, height, and trunk-cephalic height and obtained their bone age using the Tanner-Whitehouse 3 classification method. We also filmed small-sided games in the goal keeper/three player (GK3-3GK) format to analyze the centrality of their passing actions on the following measures: degree of centrality, closeness of centrality, degree of prestige, and proximity of prestige. There were no group differences in the prominence of passing actions across these three measures (tmean = −3.13; p> .05). Canonical correlations of these relationships were significant only in the U-13 group, in which centrality in passing actions was related to body size (r = 0.71; R2 = 0.21; ʌ = 0.28; p = .03). U-13 players who were physically larger and who presented higher bone age showed centralized main passing actions.

Authors:Nuno Gameiro, Filipe Rodrigues, Raúl Antunes, Rui Matos, Nuno Amaro, Miguel Jacinto, Diogo Monteiro Abstract: Perceptual and Motor Skills, Ahead of Print. Our purpose with this study was to analyze trail runners’ psychological variables of mental toughness (MT) and resilience, and their associations with runners’ performances within a quantitative cross-sectional study. In total, we analyzed data from 307 Portuguese trail runners (60 female, 247 male), aged between 20 to 66 years (M age = 41.98; SD = 7.74). The results showed that the measurement model, including the factors of MT, resilience, and performance variables, exhibited an adequate fit to the data: χ2 = 150.01 (74); BS-p = .003; CFI= .953; TLI = .942; RMSEA = .058 90% (.045, .071) and SRMR= .042. Standardized direct effects revealed positive associations between these variables. More specifically: (a) MT was significantly associated with resilience; and (b) resilience was significantly associated with performance. The indirect regression paths showed that MT was positively associated with performance, with resilience considered a possible mediator (β = .09 IC = .010, .168; p = .02). In total, considering direct and indirect effects, the model explained 21% of performance variance among trail runners.

Authors:Markel Rico-González Abstract: Perceptual and Motor Skills, Ahead of Print. The development of Emotional Intelligence (EI) has gained importance in the context of goals to spur a new generation of people intent upon improving human health. Physical education (PE) is a suitable curriculum subject in which to train EI. Therefore, our aim in this review is to summarize existing literature pertaining to EI within PE, while seeking particular guidance on how to best teach EI. We systematically reviewed PubMed, ERIC, Education Database, Scopus, SPORTDiscus, Cochrane, and FECYT (i.e., Web of Sciences, CCC, DIIDW, KJD, MEDLINE, RSCI, and SCIELO) databases up to January 24, 2022. From 248 studies initially located, 28 were included in a final qualitative synthesis. These 28 studies were sub-divided into (i) correlation and (ii) intervention studies with an intervention group, possibly a control group, and with pre-test and post-test outcome measures. There was a clear correlation between EI-motivation and EI-psychological needs, and there emerged the following types of educational programs for developing EI within PE: (a) pedagogical models based on corporal expression and relaxation, (b) Cooperative Learning (e.g., the Sport Education Model), (c) community engagement interventions (e.g., Social-Emotional Learning, the Teaching Personal and Social Responsibility model, and Service Learning), and (d) augmented reality games. Most successful EI programs included themes of collaborative work, concern for others, and social welfare. Including EI as a PE goal will require developing students’ personality and encouraging PE teachers to focus on EI within pedagogical models based on community engagement.

Authors:Akiko Fujiki, Shinkichi Nishihara Abstract: Perceptual and Motor Skills, Ahead of Print. While previous studies found that origami, when used for cognitive training and education, can improve spatial ability, the underlying mechanisms of this change, presumably associated with the origami folding process, remain unclear. In the present study, we focused on origami imagery in which participants imagined the process of folding paper to create a work of art; and we examined the cognitive factors involved in the imagery process and their association with mental transformations and the extent to which visual imagery was vivid. We identified four specific relevant cognitive factors in origami imagery: (a) controllability of origami transformations, (b) visual imagery of shapes, (c) hand sensations, and (d) visual imagery of colors. We associated the first two of these with non-rigid transformations: the controllability of origami transformations and the visual imagery of shapes. Moreover, vividness of visual imagery was related to all four cognitive factors. We propose this cognitive model of origami as one that considers the key relationships between origami imagery, mental transformations, and vividness of visual imagery.

Authors:Mehmet Duray, Aziz Dengiz, Erdogan Kavlak, Serife Tutar Abstract: Perceptual and Motor Skills, Ahead of Print. Cerebral palsy (CP) involves trunk impairment, leading to decreased postural control that is an important contributor to problems maintaining daily activities without undue fatigue. Our aim in this research was to determine the effects of trunk impairment on fatigue and balance in children with hemiplegic CP. We included 65 ambulatory children with CP in this cross-sectional study, and we grouped them into those with greater trunk impairment (Group 1, n = 33) and lesser trunk impairment (Group 2, n = 32) according to their scores on the Trunk Imparment Scale (TIS). We assessed their fatique level using the Pediatric Quality of Life Inventory™ Version 4.0 Multidimensional Fatigue Scale (PedsQL-MFS), and their balance ability using the Pediatric Balance Scale (PBS). We found that the PedsQL-MFS parameters, except the general and cognitive fatigue scores, were significantly better for participants in Group 2 than in Group 1; however Group 2 showed significantly higher scores for balance ability than did Group 1 (p < .001). All of the TIS parameters were significantly correlated with sleep/rest fatigue, and PBS scores and trunk coordination were also significantly correlated with general fatigue (p = .013) and cognitive fatigue (p = .003) which are subparameters of the PedsQL-MFS and PBS (p < .001). However static balance was highly and negatively correlated with cognitive fatigue (p < .037).Increased trunk impairment contributed to the exacerbation of fatigue and balance problems in children with hemiplegic CP. Inadequate trunk control was associated with poor sleep and poor resting quality rather than perceived general and cognitive fatigue.

Authors:Denis Hauw, Vincent Gesbert, Fabienne Crettaz von Roten Abstract: Perceptual and Motor Skills, Ahead of Print. In this study we examined changes in a psychological skill set, defined as crucial for the growth of talented athletes, through repeated assessments of the six-factor Psychological Characteristics of Development Excellence Questionnaire (PCDEQ). In a first phase of this study, we built and evaluated a French adaptation of the PCDEQ: the PCDEQ-SV (18 items). After confirmatory factor analysis, Cronbach’s alpha revealed that scales for its six factors ranged from very good to just below minimally acceptable as a model fit. The mean inter-item correlations for the scales, built on three items per scale, were optimal, leading us to assume that this short version was reliable. In the second phase, we analyzed the changes in the skill sets of 67 talented Swiss athletes who were given the PCDEQ-SV three times over 1 year. Feedback on the scores was provided to participants in comparison to the test’s cutoffs after T1 and T2. The analysis then focused on those who scored below the cutoffs and their resources for skill improvements. We found that the highest number of participants scored below the cutoffs at testing times, T1 and T2 on Factors 2, 6 and 1. Changes in scores were characterized by overall dynamics of improvement. The resources most used to effect those changes were “personal work with no outside help,” “discussions with significant others,” and “specific work with the coach.” The results are discussed in relation to the iGen’s resources for self-determination of psychological skills improvement.

Authors:Xiao-Qian Wen, Jun Zhang, Jie Ren Abstract: Perceptual and Motor Skills, Ahead of Print. While the ability to coordinate movements temporally with rhythmic auditory stimuli is universal, previous investigators showed that accurate rhythm reproduction depends on temporal complexity. To date, the effect of multiple pitches on the timing of rhythmic movements has been assumed. Exploring a possible sustained entrainment effect of auditory stimuli on sequential movement might further elucidate the role of temporal complexity and its interaction with multiple pitch engagement. Thus, we investigated the sustained effect of auditory entrainment and the interaction between temporal complexity and pitch on predefined sequential tapping with tapping sequences predefined before a synchronization-timekeeping task. Temporal complexity was manipulated by increasing the number of non-integer ratios in temporal rhythm. The rhythm sequences were presented with either multiple pitches or a single pitch. We found a reduction in mean asynchronies and ratio error in three rhythms with non-integer ratios, while inter-response interval error was reduced in the integer rhythm and the rhythm with one repetitive integer ratio and one non-integer ratio. Ratio error remanence was less in rhythms with two non-integer ratios. We found no significant difference between the two pitch types. There was a sustained entrainment effect of sequential tapping that varied with differing temporal complexity, and pitch information was not essential for auditory entrainment. These findings provide support for possible interventions aimed at motor learning. Citation: Perceptual and Motor Skills PubDate: 2023-03-20T09:43:57Z DOI: 10.1177/00315125231162748

Authors:Giulia Prete, Danilo Bondi, Nicola Mammarella, Vittore Verratti, Luca Tommasi Abstract: Perceptual and Motor Skills, Ahead of Print. Altitude hypoxia can impair sensory and cognitive functions, from causing slowed responses to sensory hallucinations. In a field study, we tested 12 expeditioners at varied altitudes (low: 1696 m; high: 4556 m) with a simple auditory detection task and a dichotic listening paradigm in which a voice was presented, lateralized, within a binaural white noise stream. Slower reaction times and a reduced right ear advantage might be expected at high (vs. low) altitude, due to hypoxia. The participants’ performances on both tasks did not differ between conditions, revealing that these functions are resistant to short-term hypoxia in young healthy adults.

Authors:Shigeki Matsuda, Hiroaki Ishigaki Abstract: Perceptual and Motor Skills, Ahead of Print. We investigated recent trends in relative age effect (RAE) findings of top-level female soccer players in Japan, using data from the 2016 to 2020 seasons. We conducted two main analyses: (a) An examination of RAE for all registered players in the Japan Women’s Soccer League (Nadeshiko League) from 2016 to 2020; and (b) an examination of RAE of newly registered players in the league from 2017 to 2020. In the first analysis, we found a significant difference between the number of players born in Q1 (April–June) versus Q4 (January–March), with the number of players born in Q1 greater and with the ratio between these groups ranging from 1.5 to 1.7. In the second analysis, we found a significant relationship between Q1 and Q4 for the 2017 season alone. However, the Q1/Q4 ratio ranged from 1.4 to 1.9, and the semester ratio of S1 (Q1 + Q2))/S2 (Q3 + Q4) ranged from 1.2 to 1.3, suggesting a birth month bias. Thus, there was a RAE in female soccer players playing recently in Japan’s top-level leagues; and the size of the effect did not change significantly across recent seasons.

Our purpose in this study was to analyze perceptual and cardiovascular responses in low-load resistance training (RT) sessions associated with a fixed non-elastic band compressed to the proximal region of the arms (p-BFR) versus a pneumatic cuff inflated to a pressure of 150 mmHg (t-BFR). Participants (16 healthy trained men) were randomly assigned to two conditions of low-load RT (20% one repetition maximum [1RM]) with BFR (p-BFR or t-BFR). In both conditions, the participants performed five exercises (4 sets/30-15-15-15) for the upper-limbs, but in one of the conditions, the exercises were performed with a p-BFR induced by a non-elastic band, while in the other, the exercises were performed with a t-BFR using a device with similar width. The devices used to generate the BFR had similar widths (5 cm). Brachial blood pressure (bBP) and heart rate (HR) were measured before, after each exercise and after the experimental session (5-, 10-, 15-, and 20 min post-session). Rating of perceived exertion (RPE) and rating of pain perception (RPP) were reported after each exercise and 15 minutes post-session. HR increased during the training session in both conditions, with no differences between p-BFR and t-BFR. Neither intervention increased diastolic BP (DBP) during training, but there was a significant post-session reduction in DBP in the p-BFR, with no differences observed between conditions. There were no significant differences in RPE and RPP in the two training conditions, with both conditions associated with higher RPE and RPP at the end versus beginning of the experimental session. We conclude that when BFR device width and material are similar, low-load training with t-BFR and p-BFR promotes similar acute perceptual and cardiovascular responses in healthy trained men.

Authors:João Mota, João Martins, Marcos Onofre Abstract: Perceptual and Motor Skills, Ahead of Print. We examined the construct validity and reliability of the previously developed Psychological and Social modules of the Portuguese Physical Literacy Assessment Questionnaire (PPLA-Q) using Mokken Scale Analysis in a sample of 508 Portuguese adolescents in public schools in Lisbon. We used a retest subsample (n = 73) to calculate the Intraclass Correlation Coefficient. Eight PPLA-Q scales can be interpreted as moderate-to-strong Mokken scales (H = .47–.66) with good total-score reliability (ρ = .83–.94), and moderate-to-excellent test-retest reliability (ICC95%CI = .51–.95); four scales had an interpretable invariant item ordering. All but the Physical Regulation scale functioned similarly across sex. Scale-scores correlated as expected, with low-to-moderate correlations across domains supporting convergent and discriminant validity. These results support the construct validity and reliability of the PPLA-Q to assess the psychological and social domains of physical literacy in Portuguese adolescents (15–18 years) enrolled in physical education.

Authors:Leonor Henriques, Diogo S. Teixeira Abstract: Perceptual and Motor Skills, Ahead of Print. Affective responses have been considered key determinants for exercise adherence, but research on affective responses to stretching activities is scarce. Given the role of these responses in exercise adherence, our aim in this review was to explore (a) the utility and feasibility of core affect in stretching-related activities as measured by the Feeling Scale (FS) and/or the Felt Arousal Scale (FAS); (b) the timing of administering these scales; and (c) the scales’ applicability and interpretability in this context. Inclusion criteria for studies in this review were experimental and non-experimental studies written in English that based affect assessment on the FS and/or FAS and that applied these scales to participants engaged in physical activity, individually or in groups. We also considered studies that focused on stretching activities that were either isolated or components of a class/activity and studies that used healthy participants of any age. Exclusion criteria were populations with mental health problems, cancer, diabetes, hypertension, cardiovascular disease, or diseases likely to alter pain perception or be associated with chronic pain, instrument validation studies, gray literature, and systematic reviews. We searched PubMed, SPORTDiscus and PsycINFO databases, and we added studies retrieved manually from reference sections while following PRISMA guidelines. We used the Effective Public Health Practice Project tool for judging methodological quality of research articles. Our final analyses were based on 12 empirical studies published between 2003 and 2021with a total of 718 participants. Both scales were found to be useful and feasible in the most usual places for exercise, but core affect results cannot be properly interpreted due to variability of study protocols and the absence of guidelines for adequate baseline assessment. Most studies recorded affect responses pre-session, during session, and post-session. We observed no standardized timing or frequency of assessment, and there was high heterogeneity among stretching protocols. Currently, research in core affect assessment of stretching-related activities lacks sufficient methodological quality to draw generalizable conclusions.

Authors:Fabricia Q. Loschiavo-Alvares, Rodolfo N. Benda, Guilherme M. Lage, Rodrigo Nicolato, Herbert Ugrinowitsch First page: 581 Abstract: Perceptual and Motor Skills, Ahead of Print. In this study, we aimed to investigate the influence of executive functions (EF) on motor adaptation. We compared the motor performance of adults with and without EF deficits. Those with EF deficits (n = 21) were individuals with attention deficit hyperactivity disorder (ADHD) under medical treatment, and those without EF deficits (n = 21) comprised a control group (CG) of participants who were also without neurological or psychiatric diagnoses. Both groups performed a complex coincident timing motor task and various computerized neuropsychological tests for assessing EF. To investigate motor adaptation, the motor task provided measures of absolute error (AE) and variable error (VE) to reflect, respectively, performance accuracy and consistency relative to the task goal. We used reaction time (RT) to measure planning time taken before starting the task. First, participants practiced until they reached a criterion of performance stabilization (prior to their exposure to motor perturbations). They were next exposed to fast and slow predictable and unpredictable perturbations. On all neuropsychological tasks, participants with ADHD scored more poorly than control participants (p < .05); participants with ADHD also performed worse than control participants on all motor measures, particularly under unpredictable perturbations (p < .05). Under slow perturbations, EF deficits, particularly attentional impulsivity, negatively affected motor adaptation while cognitive flexibility was related to performance improvement. Under fast perturbations, both impulsivity and fast reaction time were related to improvement in motor adaptation under both predictable and unpredictable perturbations. We discuss the research and practical implications of these findings. Citation: Perceptual and Motor Skills PubDate: 2023-03-10T04:24:44Z DOI: 10.1177/00315125221150100

Authors:Umut Apaydın, Rabia Eraslan, Aymen Balıkçı, Bülent Elbasan First page: 607 Abstract: Perceptual and Motor Skills, Ahead of Print. In this study we translated the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) into Turkish, adapted the instrument culturally, examined its psychometric properties within a Turkish population, and identified its limitations. We administered the AHEMD-IS to families of 65 premature or full-term Turkish infants and repeated this testing for 17 families after one-two weeks to establish test-retest reliability. We calculated the Intraclass Correlation Coefficient (ICC) and Cronbach alpha coefficient to assess reliability, and we evaluated test validity using the Spearman’s correlation coefficient and correlations with the Bayley-III motor development score. The Cronbach Alpha coefficient of the questionnaire was 0.846, and, for test-retest reliability, the ICC score was 0.830. The Turkish AHEMD-IS total score was moderately correlated with the Bayley-III fine motor development score (r = 0.469, p < 0.001), the Bayley-III gross motor development score (r = 0.533, p < 0.001), and the Bayley-III total motor development score (r = 0.526, p < 0.001). The Turkish version of the AHEMD-IS was found to be valid and reliable for children born prematurely or at full-term. The use of this questionnaire in Turkey will facilitate the creation of a home environment that will support motor development in children between 3-18 months of age.

Authors:Damian G. Kelty-Stephen, Jinhyun Lee, Keith R. Cole, Richard K. Shields, Madhur Mangalam First page: 622 Abstract: Perceptual and Motor Skills, Ahead of Print. An adaptive response to unexpected perturbations requires near-term and long-term adjustments over time. We used multifractal analysis to test how nonlinear interactions across timescales might support an adaptive response following an unpredictable perturbation. We reanalyzed torque data from 44 young and 24 older adults who performed a single-leg squat task challenged by an unexpected mechanical perturbation and a secondary visual-cognitive task. We report three findings: (a) multifractal nonlinearity interacted with pre-perturbation torque production and task error to presage greater pre-voluntary feedforward increases and greater voluntary reductions, respectively, in post-perturbation task error; (b) multifractal nonlinearity presaged relatively smaller task error than standard deviations of both pre-perturbation torques and pre-perturbation task error; and (c) increased task demand (e.g., age-related changes in dexterity and dual-task settings) led to multifractal nonlinearity presaging reduced task error. All these results were consistent with our expectations, except that a pre-perturbation knee torque-dependent increase in post-perturbation task error appeared later for older than for younger participants. This correlational multifractal modeling offered theoretical clarity on the possible roles of nonlinear interactions across timescales, moderating both feedforward and feedback processes, and presaging greater stability when the standard deviation is relatively large and task demands are strong. Thus, multifractal nonlinearity usefully describes movement variability even when paired with classical descriptors like the standard deviation. We discuss potential insights from these findings for understanding suprapostural dexterity and developing rehabilitative interventions.

Hardy, Amir Shams First page: 658 Abstract: Perceptual and Motor Skills, Ahead of Print. Motor competence (MC) has been extensively examined in children and adolescents, but has not been studied among adults nor across the lifespan. The Test of Motor Competence (TMC) assesses MC in people aged 5–85 years. Among Iranians, aged 5–85 years, we aimed to determine the construct validity and reliability of the TMC and to examine associations between TMC test items and the participants’ age, sex, and body mass index (BMI). We conducted confirmatory factor analysis (CFA) to evaluate the TMC’s factorial structure by age group and for the whole sample. We explored associations between the TMC test items and participant age, sex, and BMI using a network analysis machine learning technique (Rstudio and qgraph). CFA supported the construct validity of a unidimensional model for motor competence for the whole sample (RMSEA = 0.003; CFI = 0.998; TLI = 0.993) and for three age groups (RMSEA 0.95). Network analyses showed fine motor skills to be the most critical centrality skills, reinforcing the importance of fine motor skills for performing and participating in many daily activities across the lifespan. We found the TMC to be a valid and reliable test to measure MC across Iranians’ lifespan. We also demonstrated the advantages of using a machine learning approach via network analysis to evaluate associations between skills in a complex system.

Rodrigues, Cristina dos Santos C. de Sá, Cristhina Bonilha Huster Siegle, Patrizia Tortella, Guido Fumagalli, Rita Cordovil First page: 680 Abstract: Perceptual and Motor Skills, Ahead of Print. The COVID-19 pandemic forced governments to implement measures that disrupted the daily routines of many families worldwide. We studied how the COVID-19 lockdown affected children’s routines in Portugal (PT), Brazil (BR), and Italy (IT) to determine if children’s age and country impacted their physical activity (PA) and sedentary time. We launched an anonymous online survey to assess how 3–12 years old children adjusted their daily routines to this situation. Parents reported the times each child was engaged in different activities throughout the day, and we used these data to calculate separately overall sedentary and physical activity time. We conducted separate analyses of variance for age and country on the percentage of time spent in the different activities. Results, based on the data from 3045 children in these three countries (PT n = 2044; BR n = 836; IT n = 165), showed that, during lockdown, most children spent most of their awake daily hours in sedentary activities. There was a clear age effect on the way their routines were organized. Percentages of time spent in intellectual activity, playful screen activity, and overall sedentary time were greater in the older age groups, whereas percentages of time spent in play (with and without PA) and in overall PA were greater in the younger groups. We found a main effect of country for all variables except play without PA. The country effect was mainly due to the difference between the routines in BR when compared to PT and IT. Values of playful screen time and overall sedentary activity were higher in BR than in the two European countries. Conversely, values for play with PA, PA, and overall PA (except in the older group) were lower in BR. Patterns of time spent in these activities were similar in IT and PT, but PA and overall PA times were higher in the two younger age groups in IT. In summary, percentage of PA time of confined children was low and decreased with age across all three countries and was particularly low for children in BR relative to those in PT and IT.

Authors:Elvan Felekoğlu, Melissa Köprülüoğlu, Merve Kinik, İlknur Naz First page: 700 Abstract: Perceptual and Motor Skills, Ahead of Print. The 6-Minute Step Test (6-MST) is a simple, inexpensive field test that is increasingly used to evaluate cardiorespiratory fitness. Whether sufficient performance is revealed by this test and the effect on it of motivational factors such as music is unknown. In this cross-sectional, randomized, and crossover research design, we aimed to analyze 6-MST performance and test outcomes in different music-related auditory conditions of non-musical/non-rhythmic [NM/NR], musical/non-rhythmic [M/NR], and musical/rhythmic [M/R]). We had 38 healthy young adults (M age = 21.21, SD = 1.21 years; 60% male) complete all tests, and we measured their number of steps taken, heart rate, blood pressure, respiratory rate, peripheral oxygen saturation, perceived dyspnea, and fatigue on the modified Borg scale. We recorded individually calculated submaximal values according to heart rate reached after three tests. The number of steps increased in the M/R condition relative to other conditions (p = 0.003), and the amount of change in perceived leg fatigue was also higher in the M/R condition (p < 0.017). Despite variable test performances in different auditory conditions, we found no statistically significant difference in cardiovascular fitness and symptoms (p> 0.05). We concluded that the 6-MST is a useful tool for assessing maximum cardiac tolerance, especially if administered while listening to rhythmic music.

Authors:Ilona Bidzan-Bluma, Magdalena Jochimek, Małgorzata Lipowska First page: 714 Abstract: Perceptual and Motor Skills, Ahead of Print. Our main aim in this study was to investigate cognitive functioning in young gymnasts. The study group consisted of 86 children, aged 10–12 years: (a) a criterion group of 41 juvenile athletes (Mage = 11.23; SDage = 0.93) who trained six times per week; and (b) a comparison group of 45 children (Mage = 11.11; SDage = 0.61) who were not involved competitively in sports but who were mostly quite physically active. We measured attention, memory processes, and bioelectrical brain activity in the central region (Cz; where there are connections to motor control, movement, and sensation). We found significant differences between our two participant groups in short-term memory, deferred naming memory, and long-term memory of visual material. Children who practiced gymnastics had a better attention span than those who did not, and children who were non-athletes but who undertook physical activity more frequently than five times per week had a different theta/sensory motor rhythm (SMR) brain wave ratio (with SMR higher), meaning that they felt calmer and more relaxed.

Soble First page: 770 Abstract: Perceptual and Motor Skills, Ahead of Print. Embedded validity indicators (EVIs) derived from motor tests have received less empirical attention than those derived from tests of other neuropsychological abilities, particularly memory. Preliminary evidence suggests that the Grooved Pegboard Test (GPB) may function as an EVI, but existing studies were largely conducted using simulators and population samples without cognitive impairment. In this study we aimed to evaluate the GPB’s classification accuracy as an EVI among a mixed clinical neuropsychiatric sample with and without cognitive impairment. This cross-sectional study comprised 223 patients clinically referred for neuropsychological testing. GPB raw and T-scores for both dominant and nondominant hands were examined as EVIs. A known-groups design, based on ≤1 failure on a battery of validated, independent criterion PVTs, showed that GPB performance differed significantly by validity group. Within the valid group, receiver operating characteristic curve analyses revealed that only the dominant hand raw score displayed acceptable classification accuracy for detecting invalid performance (area under curve [AUC] = .72), with an optimal cut-score of ≥106 seconds (33% sensitivity/88% specificity). All other scores had marginally lower classification accuracy (AUCs = .65–.68) for differentiating valid from invalid performers. Therefore, the GPB demonstrated limited utility as an EVI in a clinical sample containing patients with bona fide cognitive impairment.

High scores on Harm Avoidance (HA) on Cloniger’s Temperament and Character Inventory (TCI) have been identified as a risk factor for depression. Group cognitive-behavioral therapy (GCBT) has been found effective in preventing depression and improving depressive symptoms among university students. However, no randomized controlled trials of GCBT have been conducted with university students with high HA. Although we initiated a randomized controlled trial in this study, some participants submitted incomplete questionnaires at baseline interfering with assured randomization; therefore, we report this study as a non-randomized controlled trial. We evaluated whether a GCBT intervention would be effective at reducing HA and, thereby, preventing depression in university students with high HA. We performed final analysis of data on 59 participants in the intervention group and 60 in a control group. We used scores on the Beck Depression Inventory-II (BDI-II) as the primary outcome measure and analysis of covariance to assess group differences on mean BDI-II change scores before the intervention and at six months and one year after the intervention. The intervention group had lower BDI-II scores than the control group at six months after the intervention. GCBT may have facilitated cognitive modification in individuals with high HA, or GCBT may have fostered mutual modeling by group participants. Thus, GCBT may contribute to reducing depressive symptoms in university students with high HA, and associated risk for developing depression.

Authors:Najmeh Parhiz Meymandi, Mohammad Ali Sanjari, Alireza Farsi First page: 808 Abstract: Perceptual and Motor Skills, Ahead of Print. In this study, we analyzed the effect of mental and muscular fatigue on the accuracy and kinematics of dart throwing. For this purpose, 28 young adults (19 females and 9 males) aged 25–35 years, without any regular experience in dart throwing, participated in this study. We evaluated their dart throwing skills in mental fatigue, muscular fatigue, and non-fatigue conditions. To induce mental fatigue, we used the Stroop task for 70 minutes and a simulated dart throwing exercise with an elastic band. In all three conditions, we collected accuracy data, based on the score of the dart on the board and the kinematic properties with a motion capture device. For analyzing the data and testing the research hypotheses, we employed ANOVA analyses with repeated measures after examining the normality of data distributions using skewness and kurtosis. We observed a significant decrease in the accuracy of dart throwing following mental fatigue (p = 0.027) and muscular fatigue (p = 0.001) compared to non-fatigue and following muscular fatigue compared to mental fatigue (p = 0.001). In the kinematic results, we observed a significant difference in the mean velocity of the elbow between different experimental conditions (p = 0.001). This variable decreased due to muscular fatigue, compared to the other two conditions. On the other hand, there was no significant difference among the three experimental conditions for the variables of elbow range of motion, shoulder range of motion, and mean velocity of the shoulder joint. These findings affirm mental and muscular fatigue effects on dart throwing and provide further detail regarding the specific aspects of these effects on dart throwing skills or other fine motor activities.

Authors:Bowen Ouyang, Jiaming Chen First page: 844 Abstract: Perceptual and Motor Skills, Ahead of Print. The neural strategies for movements of the lower extremities for landings from different landing heights in trained half-pipe snowboarders are not well known. We observed changes in brain activity as measured by electroencephalography (EEG) and lower limb muscle activity as measured by electromyography (EMG) in trained and untrained half-pipe snowboarders landing from different heights (30 and 60 cm). There were 12 trained male half-pipe snowboarders (HS) and 12 untrained participants (UP). We recorded EEG signals during motor preparation prior to dropping and EMG signals from right lateral rectus femoris (RF), tibialis anterior (TA), and gastrocnemius lateralis (GL) muscles during landings. Generally, theta power in the frontal cortex significantly increased in the preparation period compared to the resting state, while the alpha 1 and alpha 2 power values in central and parietal cortical areas decreased as dropping heights increased. Additionally, the HS group displayed greater magnitudes of change in power values in three frequency bands compared to the UP group. The HS group (relative to UP group) also showed higher normalized EMG amplitudes for RF and GL during contact, especially at 60 cm. The HS group (relative to the UP group) presented lower antagonist EMG activity and a higher GL/TA ratio at the 60 cm dropping height. Long-term specialized training might lead to greater neural modulation of predictive sensorimotor control and specific neuromuscular activation patterns during landing.

Authors:Zhanjia Zhang, Zhonghui He, Junwei Qian, Xin Qi, Jiajin Tong First page: 863 Abstract: Perceptual and Motor Skills, Ahead of Print. Previous research has shown many benefits of mindfulness for physical and psychological health, including its link to such health behaviors as increased physical activity (PA). We re-examined the association between mindfulness and PA to better understand a possible mediating role of eudaimonic well-being in this association, while controlling for participants’ age, gender, and affect. We had 738 undergraduate student participants (45.0% females; M age = 19.58 years) complete measures of trait mindfulness, eudaimonic well-being, and PA, and we used age, gender, and affect as covariates in a single-wave assessment. We conducted this mediation analysis with a bootstrapping technique to produce 10,000 resamples. We replicated findings of a significant relationship between mindfulness and enhanced eudaimonic well-being (β = 0.474, p < 0.001), which in turn contributed to increased PA (β = 0.193, p < 0.001). The bootstrapping method indicated a significant indirect effect of eudaimonic well-being (β = 0.092, 95% CI = [0.043, 0.142]) in the relationship between mindfulness and PA through eudaimonic well-being. Thus, eudaimonic well-being may mediate the connection between mindfulness and PA. College administrators should consider incorporating mindfulness into health promotion programs as a means of enhancing college students’ well-being and health behaviors.

Authors:Ricardo T. Quinaud, Kauana Possamai, Carlos E. Gonçalves, Humberto M. Carvalho First page: 876 Abstract: Perceptual and Motor Skills, Ahead of Print. We examined the influence of individual and contextual characteristics on student-athlete identities and then explored identity variations across the undergraduate college years. Our main analysis relied on a quantitative study of a large sample of cross-sectional data (n = 862: females = 490, males = 372) with follow-up data for 102 participants. We also used qualitative semi-structured interviews within a small sub-sample (n = 4) who participated in international competitions to provide deeper insight into their identities across time. We used the Portuguese version of the Baller Identity Measurement Scale (BIMS) to explore student-athlete identities, and we examined the influence of sex, student-athlete status (based on institution documents), the participant’s competitive level in the sport, and the student athlete’s university type. We modelled response probability on BIMS items with multilevel ordinal regression in a cumulative model based on the Bayesian framework. For the follow-up in-depth qualitative interviews of four participants competing at the international level, we used thematic analysis, with two independent researchers generating thematic codes. We found a non-significant trend toward a decreased student-athlete identity across the undergraduate years. Participants' statements reflected their difficulty combining both aspects of the student-athlete identity, such that they tried to shift their identities, depending on the circumstances, while their athletic identity seemed to be privileged. Hence, participants had difficulty combining a dual academic-sport career within a context oriented toward academic achievement and transition to professional life. The higher education context was unprepared to support student-athletes toward a dual academic-sport career.

Authors:Filipe Rodrigues, Diogo Monteiro, Vítor P. Lopes First page: 902 Abstract: Perceptual and Motor Skills, Ahead of Print. We investigated whether the relationship between significant others’ social support and adolescents’ physical activity (PA) is mediated by perceived barriers and benefits of PA. In this cross-sectional study, we analyzed data from 497 adolescents (girls = 272, boys = 225) aged between 12-18 years (M = 15.87, SD = 1.43) from six different middle and secondary schools. We collected data regarding social cognitive variables and PA with self-report measures and calculated the metabolic equivalent of total amount PA. We performed structural equation modeling and mediation analyses and found our proposed models fit the data. In girls, perceived PA benefits mediated the association between support provided by friends (β = .13; IC 95% = .02 .29), a best friend (β = .14; IC 95% = .03, .33), and parents (β = .07; IC 95% = .01, .18), and PA. Similarly in boys, perceived PA benefits partially mediated the association between support provided by parents (β = .09; IC 95% = .04, .37), friends (β = .11; IC 95% = .05, .40), and a best friend (β = .10; IC 95% = .05, .40) and PA. Perceived barriers to PA did not display any significant mediation role for either sex. Interventions to foster others’ support for PA, especially from a best friend, are important for promoting PA among adolescents.

Authors:James V. McCall, Xiaogang Hu, Derek G. Kamper First page: 732 Abstract: Perceptual and Motor Skills, Ahead of Print. While fine manual dexterity develops over time, the extent to which children show independent control of their digits in each hand and the impact of perinatal brain injury on this individuation have not been well quantified. Our goal in this study was to assess and compare finger force and movement individuation in 8–14 year old children with hemiplegic cerebral palsy (hCP; n = 4) and their typically developing peers (TD; n = 10). We evaluated finger force individuation with five independent load cells and captured joint movement individuation with video tracking. We observed no significant differences in individuation indices between the dominant and non-dominant hands of TD children, but individuated force and movement were substantially reduced in the paretic versus non paretic hands of children with hCP (p < 0.001). In TD participants, the thumb tended to have the greatest level of independent control. This small sample of children with hCP showed substantial loss of individuation in the paretic hand and some deficits in the non-paretic hand, suggesting possible benefit from targeted training of digit independence in both hands for children with CP.

Authors:Hóngyi Zhào, Hans-Leo Teulings, Cuiqiao Xia, Yonghua Huang First page: 750 Abstract: Perceptual and Motor Skills, Ahead of Print. The present study explores whether SVD affects bimanual coordination, which is easier to detect than by conventional, MRI-based methods. We tested nine severe SVD patients, eight non-severe (i.e., moderate or mild) SVD patients, eleven healthy age-matched controls, and eight young adults. They were grouped according to Fazekas scale and by age. Participants performed horizontal line drawings with both hands simultaneously on two pen tablets. The movements consisted of rhythmic patterns where participants used both hands to draw horizontal lines in anti-phase on two pen tablets. Each participant underwent a series of neuropsychiatric assessments. Results showed that SVD patients exhibited in each hand smaller horizontal movement amplitudes with variability larger compared to the healthy age-matched controls. Only movement amplitudes appeared to decrease significantly with severity of SVD. Interestingly, we found no relevant differences between the age-matched, elderly controls and the young controls. Therefore, this effect appeared indicative of SVD. The variability of the lines orthogonal to the horizontal lines of the left, non-dominant hand differed only between the severe SVD group and the other groups. Furthermore, partial correlations demonstrated that the mean horizontal movement amplitude of the left hand was positively associated with the clock drawing test score, and the inter-manual asynchrony of the horizontal movements was positively associated with the Trail Making Test-B time. These results indicated that SVD patients show poor bimanual coordination, as reflected by spatial features such as movement amplitudes and variabilities, and abnormal bimanual coordination was associated with executive dysfunction.

Authors:Leighton Jones, Jonathan Wheat First page: 826 Abstract: Perceptual and Motor Skills, Ahead of Print. Pleasant exercise experiences increase the likelihood of exercise adherence, and innovative strategies to promote consistently pleasant exercise experiences are needed. In this study we compared a novel nature-based virtual reality environment, a nature-based 360° video, and a control condition to test the hypothesis that greater presence in virtual space would promote positive affective experiences during exercise. Moreover, we assessed prefrontal cerebral hemodynamics using near infrared spectroscopy to explore possible neural underpinnings of dissociative strategies during exercise. Twelve participants (M = 26.2, SD = 7.7 years; M BMI = 25.5, SD = 5.2 kg/m2) completed a maximal aerobic test and three exercise conditions (Control, Virtual Reality [VR], and 360° video). The two experimental conditions differed in terms of the participants’ sense of presence (VR eliciting greatest presence), and all conditions utilized similar exercise intensity. The VR condition setting was a virtual mountain forest trail, and the 360° video was of a forest road. The 360° video was perceived as the most distracting (p = .023, d = 1.07), pleasant (p = .007, d = .75), and enjoyable (p = .029; d = .82) condition. ΔHbDiff data indicated that the control condition caused the greatest prefrontal brain activation (p = .008, d = .84). Presence was not a salient factor in distracting participants from bodily sensations during exercise, but immersion in a stimulus was. These results provide support for using head-mounted displays during exercise as a strategy to increase pleasure, with practical implications for practitioners, researchers, and individuals.
