Authors:Jesús Blanco-Ariza, Rafael E. Reigal-Garrido, José A. Domínguez-González, Verónica Morales-Sánchez, Antonio Hernández-Mendo Abstract: Perceptual and Motor Skills, Ahead of Print. Plyometric training in football is essential for enhancing athletic performance, as it allows for increasing strength and speed in gameplay. Meanwhile, mental visualization improves players’ technical play and motor performance during both training and competitions, thereby contributing to an overall sports performance enhancement. Collectively, physical and technical training is thought to boost athletes’ confidence in facing competitive demands. Our aim in the present study was to analyze the effectiveness of mental visualization during a plyometric training program for improving strength speed, and competitive self-confidence in young adult football (soccer) players. Our sample consisted of 40 male players aged between 19 and 25 years (M = 20.82; SD = 1.26). We used a quasi-experimental design with a control group and pretest/posttest measurements. The experimental group participated in an 8-week plyometric training program that incorporated visualization tasks, while the control group underwent the same program but without visualization exercises. We found significant improvements for the experimental group on vertical jump (p = .047) and speed (50-m sprints) (p < .034) tests, as well as in their perceived competitive self-confidence (p < .017). These findings suggest that combining plyometric exercises with visualization tasks may contribute to better motor learning, increased lower limb muscle speed and strength, and self-confidence to face competition.

Authors:Emine CİHAN, Elif Dilara DURMAZ, Muhammed ARCA, Cansu SAHBAZ PİRİNCCİ Abstract: Perceptual and Motor Skills, Ahead of Print. We compared the relationships between pain coping levels and pain, functional capacity, and disability among 48 patients with fibromyalgia and 48 healthy control participants. Specific characteristics of those diagnosed with fibromyalgia syndrome were documented. Participants were evaluated with the Visual Analog Scale (VAS), Pain Coping Scale (PCQ), Pain Disability Index (PDI), and Fibromyalgia Impact Questionnaire (FIQ). According to the 10 cm long VAS, fibromyalgia patients recorded pain intensity at 7 cm, significantly higher than in the control group (p < .001). All sub-scores of the PDI score were higher among patients with fibromyalgia compared to controls (p < .001). Scores on the PCQ score were higher for patients with fibromyalgia than controls on the sub-parameters of helplessness (p < .001) and medical remedies (p < .001). Functionality was lower among patients than controls (p < .001). Pain coping and pain-related disability (in areas of recreation, social activity, sexual behavior, total score) were significantly related in patients with fibromyalgia. These findings underscore the importance of comprehensive pain management and customized interventions for fibromyalgia patients to address their elevated pain intensity, reduced functionality, increased pain-related disability, and variable coping mechanisms compared to healthy controls. Understanding these correlations between pain coping strategies, functional status, and disability levels can help optimize treatment approaches and improve the quality of life for individuals living with fibromyalgia.

Authors:Lino Perez, Ovande Furtado Abstract: Perceptual and Motor Skills, Ahead of Print. The Furtado-Gallagher Children Observational Movement Pattern Assessment System (FG-COMPASS) is an observational tool using sequential decisions to assess fundamental movement skill proficiency. The current version of the test has three locomotor and five manipulative skills. Adding two more locomotor skills to the assessment tool enriches its scope, enabling a more comprehensive and nuanced evaluation of individual movement skills. We assessed expert-non-expert rater agreement and inter/intra non-expert rater reliability of two new scales for the locomotor subscale. We divided this study into two parts. In Part I, we filmed 60 children aged 5–10 years old who performed gallop and vertical jump skills. A motor behavior expert then classified the videotapes using our newly created rating scales. Next, we selected eight videos for training purposes and 24 videos for testing purposes. In Part II, 30 undergraduate students underwent rater training. Rating data were analyzed using weighted kappa (Kw) and the intra-class correlation coefficient (ICC), and these indices showed ‘very good’ agreement between the expert and the non-expert raters for vertical jump (Kw = .96) and gallop (Kw = .89). The ICC expert to non-expert rater values for vertical jump and gallop were .98 and .94, respectively; and mean kappa values for inter-rater reliability between non-experts were considered ‘very good’ for vertical jump (MKw = .92) and ‘good’ for gallop (MKw = .78). The ICC inter-rater values were .98 and .95 (considered ‘excellent’) for vertical jump and gallop, respectively; and the kappa intra-rater values were .96 and .85, respectively, with intra-rater ICC values .98 and .92. Thus, the proposed rating scales were reliable for assessing vertical jump and gallop. Future studies should focus on criterion-related validity and reliability evidence from live performances.

Authors:Jieping Xu, Yuehong Pan, Ali Derakhshan Abstract: Perceptual and Motor Skills, Ahead of Print. Since boredom significantly contributes to diminished motivation among learners of English as a Foreign Language (EFL), there is a need to identify factors that influence boredom. Amidst various elements that can precipitate students’ boredom, educational-related concepts have garnered particular attention, with the learning environment emerging as a chief focal point due to its consequential importance to learners. Specifically, the role of teachers’ clarity and immediacy in manipulating learners’ performance, enthusiasm, and involvement has been widely recognized. Consequently, in this study, we scrutinized the impact of EFL teachers’ immediacy and clarity in mitigating learners’ boredom. To this end, we collected data from 383 Chinese students through the administration of three scales measuring their perceptions of teacher clarity, teacher immediacy, and learners’ boredom. We identified significant associations between teachers’ clarity and immediacy and learners’ boredom. In Structural Equation Modeling (SEM) analysis, both teacher immediacy and clarity were robust predictors of students’ boredom, with about 48% of the variance in students’ boredom accounted for by teachers’ immediacy, and 53% of this variance attributed to teachers’ clarity. We elaborate upon the implications of these findings in our discussion. Citation: Perceptual and Motor Skills PubDate: 2024-08-08T12:29:43Z DOI: 10.1177/00315125241272524

Authors:Tomoaki Kozaki, Motoharu Takao Abstract: Perceptual and Motor Skills, Ahead of Print. Bright light impacts the human circadian system such that exposure to bright light at night can suppress melatonin secretion, and exposure to bright light in the morning prevents light-induced melatonin suppression at night. The preventive effect of morning light may attenuate the prior history of light sensitivity of intrinsically photosensitive retinal ganglion cells (ipRGCs) that regulate the circadian system. In this study, we evaluated electroretinogram (ERG) responses to red and blue flickering lights following dim and bright daylight conditions. Eleven healthy females underwent ERG measurements during exposure to 33 Hz flickering red or blue light under dim and bright daytime conditions. We averaged ERG waves for 50 flickering light pulses of the trigger signal data. We obtained the amplitude of the signal-averaged ERG by calculating the difference between the waves’ peaks and bottoms. Although there was no significant dim and bright light difference in the amplitude of ERG waves, the ERG amplitude to flickering blue light under the bright light condition was significantly lower than to flickering blue light under the dim light condition. In this study, blue light stimulated mainly ipRGCs and S-cones. Since S-cones may contribute minimally to the light-adapted 33 Hz flicker ERG results, our findings suggest that bright light during the daytime attenuates the sensitivity of human ipRGCs.

Authors:Meltem Ceylan Gencigör, Sinan Akın Abstract: Perceptual and Motor Skills, Ahead of Print. Environmental factors have a clear effect on children’s motor development and can be manipulated; while biological factors are also powerfully influential, they are more resistant to intervention. Especially in restrictive environments (e.g., the recent pandemic-related shutdown), there can be increased importance to simple, fun, at-home, indoor programs. In this study, we investigated the effects on motor skill development of a movement education program based on the Orff approach, which has long been used in music education. This was an experimental research design involving 78 children, aged 6–7 years old, in two groups (Control Group, n = 39; Experimental Group, n = 39). We used a simple randomization method to determine the groups. We measured the children’s skill levels with the Test of Gross Motor Development-2 (TGMD-2), and we analyzed data using 2 × 2 repeated-measures analyses of variance (ANOVA). Our results revealed significantly greater improvement in the children’s scores on object control (p < .001), locomotor skills (p < .001), and total TGMD-2 (p < .001) in the experimental group than in the control group. Thus, programs designed with music and rhythm can help ensure that children have fun and are better motivated to participate in activities that have a positive effect on their motor skills.

Authors:Mariana Ribeiro, Elisabete Fernandes, Mariana Borges, Madalena Pires, Xavier Melo, Fausto J. Pinto, Ana Abreu, Rita Pinto Abstract: Perceptual and Motor Skills, Ahead of Print. The Global Physical Activity Questionnaire (GPAQ) has been used often to assess physical activity (PA) patterns. However, the European Portuguese version of this instrument has not been validated. We aimed to validate the self-administered GPAQ, version 2, (GPAQv2) for Portuguese adults. We included 32 participants in a pilot study of a Portuguese adaptation of the test and 108 participants in an assessment of their PA patterns and sedentary behavior (SB) through the GPAQv2. For its validation, we compared the GPAQv2 to the International PA Questionnaire-Long Form (IPAQ-LF) (concurrent validity) and the ActiGraph wGT3X-BT accelerometer (criterion validity). We evaluated PA and SB at baseline and after seven consecutive days. Test-retest reliability with the Kappa test (k) and the Intraclass Correlation Coefficient (ICC) ranged from strong to almost perfect (k: 0.864–0.976) and from moderate to excellent (ICC: 0.56–0.994), respectively. Concurrent validity, assessed by Spearman’s Correlation Coefficient, was moderate to substantial (rho: 0.471–0.680), and there was fair to substantial criterion validity (rho: 0.226–0.672). Bland-Altman plots showed that the GPAQv2 overestimated vigorous and moderate to vigorous PA and underestimated moderate PA. The largest difference values were related to SB, since the GPAQv2 underestimated sitting time. In sum, we found the GPAQv2 to have acceptable validity and reliability for assessing PA and SB patterns, and we recommend its use for Portuguese adults.

Authors:Jalleli Dorra, Sana Jarraya Abstract: Perceptual and Motor Skills, Ahead of Print. We assessed the effect of a one-week mindfulness-based intervention on resilience, social behavior, and motor skills in four to five-year-old children. In this randomized controlled trial, 45 children (22 females; 23 males; M age = 4.5, SD = 0.4 years) from the same preschool were randomly assigned to three groups: (a) a mindfulness group (MG; n = 15) that participated in five 30-min mindfulness sessions; (b) a physical activity group (PAG; n = 15) that engaged in five 45-min physical exercise sessions; and a control group (CG; n = 15) that received no intervention. Training sessions were held on five consecutive days. Prior to (T0) and after the five mindfulness sessions (T1), all participants blindly completed the Movement Assessment Battery for Children-2 (to assess their motor skills), the Strength and Difficulties Questionnaire (to evaluate their behavior), and the Child and Youth Resilience Measure-28 (to measure their resilience). At baseline (T0), there were no significant differences between the groups. The mindfulness group experienced the strongest positive effects after the intervention (T1), with improvements in both motor skills and social behavior, though there was no significant effect on resilience. Our results suggest that a brief mindfulness training intervention is a promising strategy for improving motor skills and social behavior in early childhood settings.

Authors:Vitor L. S. Profeta, Flávia N. R. Beleza, Christian A. G. Louredo Abstract: Perceptual and Motor Skills, Ahead of Print. We investigated whether allowing individuals to exchange verbal information during dyadic practice changed the effect of analogy instructions intended to strengthen explicit motor learning by an implicit means. Forty-three right-handed college students performed golf putting, aiming at a target three meters away. Participants were assigned to one of two groups: Dyadic Practice Analogy Instruction or Individual Practice Analogy Instruction. Participants in the Dyadic Practice group were allowed to communicate with one another about the task during their practice. Before practice, participants performed a working memory capacity test. Both groups performed 180 trials of golf distributed across three days. On each day, there were four blocks of 15 trials. On the third day, participants reported the explicit rules they used to learn the task and they completed the Intrinsic Motivation Inventory. On the fourth day, they took three learning tests: retention, dual-task transfer, and social pressure transfer tests. Results of the retention test indicated that both groups learned the task comparably. Similarly, there were no significant group differences between the participants’ number of explicit rules learned and their motivation levels on either of the transfer tests. Finally, only the participants in the Dyadic Practice Analogy Group showed a significant correlation between their performance on the dual-task transfer test and their working memory capacity. Overall, we found that dyadic practice did not interfere with the implicit type of motor learning promoted by analogy instruction (i.e., implicit learning).

Authors:Giovanna Soler Donofre, Camila Cremonezi Japur, Maria Fernanda Laus, Marle dos Santos Alvarenga, Wanderson Roberto da Silva Abstract: Perceptual and Motor Skills, Ahead of Print. The ORTO-15 is a commonly used screening instrument for symptoms of Orthorexia Nervosa (ON), an obsessive overconcern with healthy eating. However, its limitations have been evidenced in several published factorial models. We analyzed the psychometric properties of seven different ORTO-15 factorial models using data from Brazilian adult participants (n = 1455; 71.4% women; M age = 29.5, SD = 8.9 years) from the country’s five macro-regions who answered online questions for sample characterization and completed the Portuguese version of the ORTO-15 containing 15 items. We tested the fit of each model separately, analyzing data for men and women with separate confirmatory factor analysis, and using the Weighted Least Squares Mean and Variance Adjusted estimation method and goodness-of-fit indices. We also calculated the average variance extracted and the alpha ordinal and omega coefficients to analyze the convergent validity and reliability of the factors. None of the models tested presented adequate properties of validity and reliability. Although we found some acceptable reliability coefficients, they do not guarantee the validity of the data. Future investigators should be cautious when choosing the ORTO-15 for ON screening. Citation: Perceptual and Motor Skills PubDate: 2024-07-21T07:53:32Z DOI: 10.1177/00315125241267134

Authors:Houssem Ben Chikha, Hajer Mguidich, Bachir Zoudji, Aïmen Khacharem Abstract: Perceptual and Motor Skills, Ahead of Print. Coaches often use pointing gestures alongside their speech to reinforce their message and emphasize important concepts during instructional communications, but the impact of simultaneous pointing gestures and speech on learners’ recall remains unclear. We used eye-tracking and recalled performance to investigate the impact of a coach’s variously timed pointing gestures and speech on two groups of learners’ (novices and experts) visual attention and recall of tactical instructions. Participants were 96 basketball players (48 novice and 48 expert) who attempted to recall instructions about the evolution of a basketball game system under two teaching conditions: speech accompanied by gestures and speech followed by gestures. Overall, the results showed that novice players benefited more from instructional speech accompanied by gestures than from speech followed by gestures alone. This was evidenced by their greater visual attention to the diagrams, demonstrated through a higher fixation count and decreased saccadic shifts between the coach and the diagrams. Additionally, they exhibited improved recall and experienced reduced mental effort, despite having the same fixation time on the diagrams and equivalent recall time. Conversely, experts benefited more from instructional speech followed by gestures, indicating an expertise reversal effect. These results suggest that coaches and educators may improve their tactical instructions by timing the pairing of their hand gestures and speech in relation to the learner’s level of expertise.

Authors:Rym Baccouch, Rihab Borji, Hafedh Ayed, Sonia Sahli, Yosra Zammit, Haithem Rebai Abstract: Perceptual and Motor Skills, Ahead of Print. In the current study we aimed to investigate the effect of specific dual task training (SDTT) compared to conventional soccer training (CST) on motor and cognitive performances in U13 elite soccer players. Twenty-four young soccer players (all males) participated in this study. We measured their change of direction ability (CODA) and cognitive performances (cognitive flexibility and inhibition) before and after four weeks in either the SDTT group or the CST group. We administered the Trail-Making Test (TMT) to evaluate cognitive flexibility and the Stroop test to evaluate cognitive inhibition. We assessed CODA using the t test (TT). After training, CODA (p < .001), cognitive flexibility (p < .001), and inhibition (p < .001) were improved only in the SDTT group. These results suggest that SDTT seems more suitable than CST to optimally improve both CODA and cognitive performances in U13 elite soccer players.

Authors:Maressa Priscila Krause, Luke Haile, Dayanne Sampaio Antonio, Andre L. Peres, Robert J. Robertson Abstract: Perceptual and Motor Skills, Ahead of Print. We were interested in micro-variations in an athlete’s psychophysical state that separate peak exertion from physiological collapse. Thus, we measured perceptual acuity in runners using a classic psychophysical approach, the just noticeable difference (JND) on two standard stimuli runs at treadmill speed corresponding to 70%VO2max and 80%VO2max. Thirty-four male runners (M age = 35.26, SD = 7.33 years) first performed a maximal treadmill test to determine the speed of a standard exercise bout for the JND trials. The JND trials consisted of four 5-minute running bouts on a treadmill with 5-minute rests between bouts. For bouts 1 and 3, participants ran at the standard stimuli pace, but for bouts 2 and 4, they adjusted their speeds to achieve a level of exertion at a JND above/below the SS. They achieved differences in the final 30 seconds of the VO2 between each JND bout and the previous standard stimuli at just above (JND-A) and just below (JND-B) the JND perceived exertions. We used a Generalized Linear Model analysis to compare the JND-A and JND-B within and between ventilatory threshold groups (lower/higher) in absolute and relative VO2 and in terms of the total JND magnitude. The magnitude of JND-A was greater than that of JND-B at 70%VO2max and 80%VO2max in absolute units (70%VO2 Δ = 2.62; SE = 0.37; p < .001; 80%VO2 Δ = 1.67; SE = 0.44; p = .002) and in relative units (70%VO2max Δ = 4.70; SE = 0.66; p < .001; 80%VO2max Δ = 2.96; SE = 0.80; p = .002). The total magnitude was greater in the 70%VO2max trial than 80%VO2max in absolute units (70%VO2 M = 3.78, SE = 0.31 mL·kg−1·min−1; 80%VO2 M = 2.62, SE = 0.37 mL·kg−1·min−1; p = .020) and in relative units (70%VO2max M = 6.57, SE = 0.53%VO2max; 80%VO2max M = 4.71, SE = 0.64%VO2max; p = .030). The JND range narrowed when physiologic demand increased, for both physical (speed) and psychological (RPE) variables.

Authors:Enrique Alonso Pérez-Chao, Raúl Nieto-Acevedo, Aaron T. Scanlan, Adrián Martin-Castellanos, Alberto Lorenzo, Miguel Ángel Gómez Abstract: Perceptual and Motor Skills, Ahead of Print. This study aimed to (i) compare the extent of home-court advantage (HA) and home win percentage (HW) between Spanish basketball leagues across different playing levels (i.e., leagues) and (ii) analyze the influence of team ability on HA and HW within each playing level. We gathered data for game locations and results from open online sources for all games in the First Division (ACB), Second Division (LEB Gold), and Third Division (LEB Silver) Spanish male basketball leagues between 2010–2023. The dataset included 12 seasons, 635 teams (215 First Division, 203, Second Division, and 217 Third Division), and 19,539 games (7075 First Division, 6344 Second Division, and 5520 Third Division). We calculated HA [(total home wins/total wins) * 100] and HW [(total home wins/total home games) * 100] for each team across each season. We performed Kruskal Wallis tests, calculated partial eta squared (ηp2), and performed Mann-Whitney U tests with rank biserial correlation (rb) effect sizes and Dwass-Steel-Critchlow-Fligner pairwise comparisons to compare HA and HW between leagues and between team abilities (low, medium, and/or high) within each league. There was a significant effect for HA between leagues (p = .01) with post hoc comparisons revealing a higher HA for the First Division than for the Third Division (p = .01), but HW was not significantly different between leagues. In turn, variations in HA and HW between team abilities were consistent across playing levels, with HW significantly increasing in a progressive manner with higher team abilities (p < .001) and with HA significantly lower among high-level teams compared to lower-ability team clusters (p < .01). These findings emphasize the importance of considering playing level and team ability and interpreting HA and HW together to contextualize an apparent home advantage in Spanish basketball.

Authors:Soo Mi Nam, Ji-Won Park, Ji-Hyun Ko, Min Joo Kim Abstract: Perceptual and Motor Skills, Ahead of Print. Our primary purpose in this study was to determine whether trained dancers differed from untrained non-dancers in their ability to accurately control motor timing during finger and heel tapping tasks, both with and without slow isochronous auditory stimuli. Dancers and non-dancers were instructed to synchronize their taps with isochronous auditory stimuli under three conditions: 30, 40, and 50 BPM. After the synchronization phase, participants were asked to continue tapping without the auditory sequences. On the synchronization task, the tapping onset of both groups lagged behind the stimulus onset in all tempo conditions. In all conditions, dancers showed more accurate and stable beat synchronization and continuation than non-dancers. As the tempo condition slowed down (from 50 to 30 BPM), synchronization accuracy decreased while synchronization and continuation variability increased. Unlike for novices, dancers showed no difference between the finger and heel tapping synchronization tasks. During the continuous tasks, their timing accuracy was higher for heel than for finger tapping. Collectively, these findings suggest that dance training, which involves synchronizing bodily movements based on rhythm, may lead to an accumulation of experience that enhances specific sensorimotor skills related to synchronizing movements with external stimuli or continuing rhythmic movements temporally.

Authors:José Antonio Domínguez González, Rafael Enrique Reigal Garrido, Verónica Morales Sánchez, Antonio Hernández Mendo Abstract: Perceptual and Motor Skills, Ahead of Print. Our aim in the present study was to test the efficacy of a 13-week, 19-session psychological intervention program on young soccer players’ competitive anxiety and their sport psychological profiles. Participants were 37 players in the under-15 age category, of which 18 players formed the experimental group (M age = 14.67 years, SD = .48) and 19 players formed the control group (Mage = 14.23 years, SD = .42); this was a quasi-experimental design without random assignment to groups. We had all participants complete the Psychological Inventory of Sport Performance (IPED), the Questionnaire of Psychological Characteristics of Sport Performance (CPRD), and the Competition State Anxiety Inventory-2 (CSAI-2) before and after the intervention. Results indicated positive effects for the intervention group (but not the control group) on stress control and motivation dimensions of the CPRD, cognitive anxiety and self-confidence on the CSAI-2, and self-confidence and attentional control on the IPED. These results suggest that psychological training for athletes contributes to their improved psychological skills, providing them tools to better adapt to the competitive environment.

Authors:Russell Lowell, David Saucier, Harish Chander, Reuben Burch, Zachary Gillen Abstract: Perceptual and Motor Skills, Ahead of Print. Reacting and responding to an external stimulus is an important component of human performance, and they inform us about a participant’s neurophysiological capabilities. Our purpose in this study was to determine whether reaction times (REACT), response times (RT), and countermovement jump (CMJ) performance differ when responding to an auditory (AUD) versus visual (VIS) stimulus. Participants were 17 college-aged volunteers (6 females and 11 males; M age = 23.0, SD = 3.4 years; M height = 174.57, SD = 10.37 cm; M body mass = 73.37, SD = 13.48 kg). Participants performed CMJs on force plates immediately upon receiving an AUD or a VIS stimulus. The AUD stimulus was a beep noise, while the VIS stimulus was a light on a screen in front of the participants. We determined REACT for the tibialis anterior (TA), medial gastrocnemius (GM), vastus lateralis (VL), and biceps femoris (BF) muscles to be the amount of time between stimulus onset and the initiation of the muscle’s electromyographic (EMG) signal. We determined RT to be the amount of time between stimulus onset and the beginning of the participant’s force production. We assessed CMJ performance via ground reaction forces during the unweighting, braking, and propulsive phases of the jump. We quantified EMG amplitude and frequency during each CMJ phase. We found RT to be faster to the AUD versus the VIS stimulus (p = .007). VL and BF muscles had faster REACT than TA and GM muscles (p ≤ .007). The AUD stimulus was associated with faster CMJ unweighting phase metrics (p ≤ .005). Thus, individuals may react and respond faster to an AUD versus VIS stimulus, with limited improvements in their subsequent physical performance.

Hip osteoarthritis and total hip arthroplasty imply damaged articular and periarticular structures responsible for proprioception, and this damage may impair the accurate perception of body-weight distribution. In this study, we investigated proprioceptive abilities and accuracy perceiving body-weight distribution in patients undergoing total hip arthroplasty, and we assessed the associations between these abilities and body perception accuracy with functional mobility testing in 20 patients scheduled for total hip arthroplasty and 20 age-matched healthy participants. We assessed (a) absolute error in hip joint position sense (AE-JPS), (b) absolute error in body-weight distribution (AE-BWD) during standing and sit-to-stand tasks with open and closed eyes, and (c) functional mobility with the Timed Up and Go Test (TUG). We assessed patients undergoing hip arthroplasty before (T0) and five days after their surgery (T1), while control participants underwent a single evaluation. Relative to controls, participants undergoing surgery showed higher AE-JPS at 15° of hip flexion at T0 (p = .003) and at T1 (p = .007), greater AE-BWD during sit-to-stand with open eyes at T1 (p = .014) and with closed eyes at both T0 (p = .014) and at T1 (p < .001), and worse TUG at both T0 (p = .009) and T1 (p < .001). AE-BWD during sit-to-stand with closed eyes positively correlated with TUG at T0 (r = 0.55, p = .011) and at T1 (r = 0.51, p = .027). These findings suggested that impairments in body-weight distribution perception were evident both before and immediately after total hip arthroplasty, suggesting that these impairments may regularly mark these patients’ functional mobility problems.

Authors:Gibson Moreira Praça, Pedro Henrique de Almeida Oliveira, Vitor Hugo Santos Resende Abstract: Perceptual and Motor Skills, Ahead of Print. In this study, we examined whether experience level and various dual motor and cognitive or single tasks influenced young soccer players’ physical performance during small-sided games. Participants were 72 players from U-13 (n = 36) and U-17 (n = 36) groups who participated in 3-to-a-side small-sided games under four experimental conditions: control, a secondary motor task, an additional related secondary cognitive task, and an additional secondary non-specific task. We used GPS devices to measure physical performance in terms of distances covered and accelerations at different thresholds. We found no significant interaction effect between player experience and task condition (p = .540), meaning that dual tasks had comparable effects on players of different experience levels. There were significant main effects of both experience level (p < .001) and condition (p < .001) on most physically related variables. Older players outperformed younger ones, particularly in high-intensity actions. While secondary motor tasks decreased physical performance, secondary cognitive tasks, irrespective of specificity, did not impair players’ performances. In conclusion, experience level did not influence the players’ physical response to dual tasks, and a secondary motor task was more disruptive to physical performance than either of two types of secondary cognitive tasks. Cognitive tasks can be incorporated into soccer training without compromising physical performance. Citation: Perceptual and Motor Skills PubDate: 2024-05-28T02:16:34Z DOI: 10.1177/00315125241257398

Authors:Ana Pinho, Diogo Monteiro, Miguel Jacinto, Rui Matos, Filipe Rodrigues, Nuno Amaro, Pedro Teques, Teresa Fonseca, Raúl Antunes Abstract: Perceptual and Motor Skills, Ahead of Print. Our primary objectives in this study were to translate and provide psychometric support for the Coach Athlete Relationship Questionnaire (CART-Q) Portuguese version, assess its invariance across sex, and explore its nomological validity in relation to enjoyment. Our sample participants were 470 athletes (226 females, 244 males) aged between 16 to 39 years from various individual and team sports. We found that the translated Portuguese version of the CART-Q exhibited satisfactory test-retest reliability and can serve as a reliable tool for evaluating the core constructs of the coach-athlete relationship – closeness, commitment, and complementarity. Moreover, this instrument showed evidence of nomological validity through significant positive correlations between its underlying factors and athletes' enjoyment with their sport. The proposed model for explaining item variance was also found to be invariant between male and female respondents. We recommend further use of this instrument in research and practical applications.

Authors:Shiva Ghambari, Saeed Arsham, Hesam Ramezanzade Abstract: Perceptual and Motor Skills, Ahead of Print. Our aim in this study was to investigate the effects of motionless interventions, based on visual-auditory integration with a sonification technique, on the learning a complex rhythmic motor skill. We recruited 22 male participants with high physical fitness and provided them four acquisition sessions in which to practice hurdle running, based on a visual-auditory instructional pattern. Next, we divided participants into three groups: visual-auditory, auditory, and control. In six sessions of motionless interventions, with no physical practice, participants in the visual-auditory group received a visual-auditory pattern similar to their experience during the acquisition period. The auditory group only listened to the sound of sonified movements of an expert hurdler, and the control group received no instructional interventions. Finally, participants in all three groups underwent post-intervention and transfer tests to determine their errors in the spatial and relative timing of their leading leg’s knee angular displacement. Both visual-auditory and auditory groups had significantly less spatial error than the control group. However, there were no significant group differences in relative timing in any test phase. These results indicate that the use of the sonification technique in the form of visual-auditory instruction adapted to the athletes’ needs benefitted perception-sensory capacities to improve motor skill learning.

Authors:Hasan Bingöl, Dilan Demirtaş Karaoba Abstract: Perceptual and Motor Skills, Ahead of Print. We compared children with hemiplegic and diplegic cerebral palsy (CP) using the conceptual framework of the International Classification of Functioning, Disability and Health: Child and Youth version (ICF-CY). We enrolled 42 children with CP aged 5 – 13 years old (M age = 9.57, SD = 2.8 years). We assessed their trunk control and dynamic balance with the Trunk Control Measurement Scale (TCMS) and the Timed Up and Go test (TUG), and we used ABILHAND-Kids and Assessment of Life Habits (Life-H) to assess their manual ability and participation with activities of daily living. We administered the European Child Environment Questionnaire (ECEQ) to identify relevant environmental factors. We employed structural equation modeling (SEM) to identify specific factors contributing to potential differences between these CP groups. Children with hemiplegic CP demonstrated significantly better outcomes in terms of trunk control, dynamic balance, and environmental factors compared to those with diplegic CP (p < .05). In contrast, children with diplegic CP demonstrated superior outcomes regarding manual ability, compared to those with hemiplegic CP (p < .001). In our structural equation models, trunk control strongly predicted both dynamic balance (0.75) and environmental factors (0.74). Moreover, the relationships between trunk control and participation in daily and social activities were 0.54 and 0.47, respectively. Impaired trunk control and dynamic balance were significant contributors to increased activity restrictions and environmental barriers in children with diplegic CP. This suggests that improving disability and functioning in children with diplegic CP requires a focus on trunk control training and dynamic balance exercises.

Authors:Larissa Oliveira Faria, Thais Frois, Leonardo de Sousa Fortes, Laiss Bertola, Maicon Rodrigues Albuquerque Abstract: Perceptual and Motor Skills, Ahead of Print. We conducted two studies to evaluate the construct validity, short term test-retest reliability, and sensitivity to mental fatigue of the Stroop task when used with older adults. In Study 1, 40 participants visited our lab on two separate days. On the first visit, they took five screening scales, and we measured their height and body mass. On the second visit, they completed the Stroop task twice with a 30-minute interval between assessments. In Study 2, 15 different participants took a 30-minute Flanker/Reverse Flanker task during the interval between the two administrations of the Stroop tasks and they gave subjective ratings of their mental fatigue on the Visual Analogue Scale (VAS) prior to taking either of the Stroop tasks. In Study 1, participants showed a ceiling effect on the Stroop accuracy measure, there was strong concurrent validity for the Stroop with significant score differences between the Stroop’s congruent and incongruent conditions (p < .001), and there was excellent response time reliability (ICC = 0.926) on day two when participants took the Stroop twice within a 30-minute inter-test interval. However, there were significant test-retest performance differences with respect to cognitive inhibition (p < .001). In Study 2, mental fatigue from the Flanker/Reverse Flanker test resulted in a significantly worse second Stroop performance (p = .045). We concluded that the Stroop task demonstrated strong concurrent validity and response time reliability among older adults, but it showed sensitivity to mental fatigue, and repeated administrations within the short 30-minute test-retest interval revealed that the most important Stroop measure (cognitive inhibition) was unreliable. We discuss the implications of these findings. Citation: Perceptual and Motor Skills PubDate: 2024-05-13T02:10:17Z DOI: 10.1177/00315125241253425

Authors:Naoki Hamada, Ryo Tsujinaka, Hitoshi Oda, Shiho Fukuda, Masakazu Matsuoka, Hiroshi Kunimura, Koichi Hiraoka Abstract: Perceptual and Motor Skills, Ahead of Print. In the present study, we examined the immediate effect of allowing healthy participants to view their mirror-reflected body image on static and dynamic balance. We placed a mirror to allow participants to frontally view their own body image while maintaining a quiet stance or while engaged in a dynamic postural standing task. On measures of body sway during quiet stance, there were no effects of this visual feedback, supporting the view that human beings have no central mechanism for viewing the mirror-reflected body image to control body sway during quiet stance. However, the body deviated forward during quiet stance while viewing the mirror-reflected body image, indicating that viewing the mirror-reflected body image contributed to the anterior-posterior positioning of the body, as mediated by an ankle control strategy. For the dynamic standing task, viewing the body image induced unstable peaks of rhythmic lateral shifting of the body weight over the feet. This indicates that viewing the body image caused unstable motor commands for rhythmic lateral weight shifting. When participants made a transition from a bipedal to a unipedal stance in response to a cue, viewing the body image shortened the onset latency of the body sway. Accordingly, viewing the body image seemed to accelerate the motor execution involved in lateral weight shifting, possibly due to predictive activation of the motor system before movement onset. Considered collectively, we found static and dynamic stance balance to be influenced by viewing one’s mirror-reflected body image. Viewing the mirror-reflected body image may be a means of changing static and dynamic balance in patients with impaired postural control.

Authors:Walton Wider, Nicholas Tze Ping Pang, Jiaming Lin, Muhammad Ashraf Fauzi, Leilei Jiang, Jem Cloyd M. Tanucan Abstract: Perceptual and Motor Skills, Ahead of Print. In this article, we offer an exhaustive analysis of academic work on psychological flexibility using bibliometric techniques. We identify emerging trends in a dataset of 3535 scholarly articles from the Web of Science database. We highlight key publications, map out the field’s intellectual framework, and anticipate future research avenues through co-citation and co-word analytics. The co-citation assessment revealed five distinct clusters, while the co-word analysis showed three. Although research regarding psychological flexibility has gained recent popularity, there remains a need for more scholarly initiatives to achieve a nuanced understanding of this subject.

Authors:Doheung Lee, Sangwook Kang Abstract: Perceptual and Motor Skills, Ahead of Print. Our purpose in this study was to investigate the relationship between self-efficacy, fear of failure, competitive state anxiety, and flow among elite golfers. We surveyed 375 elite golfers (N = 375; male = 187, female = 188) who were registered with the Korean Sports and Olympic Committee, and we analyzed their survey responses using descriptive statistics, confirmatory factor analysis, correlation analysis, and structural equation modelling. As expected, we found golf self-efficacy (GSE) to be significantly related to fear of failure (FOF). We also found FOF and competitive state anxiety (CSA) significantly related to flow. Finally, we verified a suspected hierarchical or mediating effect in these relationships such that we verified predictive relationships of flow as follows: GSE→FOF→CSA→Flow. These golfers’ self-efficacy had a buffering effect of lowering their FOF and CSA in the pathway toward flow. A suggested implication of these findings is that to enhance a golfer’s performance by minimizing interfering psychological factors, it is essential to boost their self-efficacy.

Authors:Dongmin Kim, Woongrae Roh, Yongho Lee, Sanghun Yim Abstract: Perceptual and Motor Skills, Ahead of Print. In this study we investigated the effects of an 8-week table tennis exercise program with a task-oriented approach on visual perception and motor performance of 31 adolescents with developmental coordination disorder (DCD). The participants were identified by their teachers as having greater difficulty than their peers (450 students from three Korean middle schools) in physical education (PE) classes. On the Bruininks-Oseretsky Test of Motor Proficiency-2, these adolescents scored below the 15th percentile and showed difficulties in performing daily life activities due to motor performance problems; they did not have physical defects, intellectual or neurological impairments, or Attention Deficit Hyperactivity Disorder. Of 98 prospective adolescents with PE difficulties, we obtained personal assent and parents’ informed consent from 54, and 31 of these met screening criteria for DCD through the Developmental Coordination Disorder Questionnaire-Korean. This final group was divided in non-random fashion (based on the proximal geographic grouping of the children’s schools) between an experimental group (n = 16) and a control group (n = 15). The experimental group participated in the 8-week task-oriented table tennis training program with three 90-minute sessions per week, while the control group only participated in regular PE classes twice per week. We measured participants’ visual perception and motor performance in the same environment before and after the intervention program. Participants’ visual perception was significantly more improved in the experimental group than the control group, with specific improved skills in visual-motor search, visual-motor speed, figure-ground, and visual closure; copying and perceptual constancy skills did not improve significantly. In addition, total motor performance and motor sub-skills, including fine manual control, manual coordination, body coordination, strength, and agility were significantly more improved in the experimental group than in the control group. Thus, our task-oriented table tennis exercise program was of greater assistance than general PE classes for improving visual perception and motor performance in adolescents at risk of DCD.

Authors:Frederico Ribeiro Neto, Luiz Gustavo Teixeira Fabrício dos Santos, Luis Felipe Castelli Correia de Campos, Ciro Winckler, Rodrigo Rodrigues Gomes Costa Abstract: Perceptual and Motor Skills, Ahead of Print. Improvements in race times for male and female Para canoe athletes across different sports classes have led to a reduction in relative differences between classes over time. However, there is a lack of research examining the comparative developmental trajectories between high-performance Paralympic (PCS) and Olympic (OCS) canoe sprint. In this study, we compared the developmental trajectories of 200-meter kayak performances among PCS and OCS athletes. In total, we analyzed 628 race results obtained from public online databases, for nine competitions between 2015 and 2023. Race times were reduced over the years except in specific sports classes (KL3-M, K1-M, and K1-F; KL: Kayak Level, M: male, F: female), with a poor positive correlation (r = 0.17 to 0.33) between time and the years. For the remaining sports classes, these correlations ranged from poor to fair (r = −0.58 to −0.13). OCS K1 athletes outperformed their Paralympic counterparts. Among Paralympic classes, KL1 had slower times than KL2 and KL3 (p ≤ .05), with KL2 times significantly lower than KL3 in the female category. OCS athletes exhibited less variability in race times compared to PCS athletes. In the male category, there were no significant differences in the coefficients of variation (CV) and amplitude of race times between sport classes, except for KL1-M, which had a larger CV than K1 (p ≤ .05). In the female category, the CV and amplitude of race times were significantly higher in KL1-F compared to KL3-F and K1-F. OCS times remained stable from 2015, with KL3-M following a similar trend. PCS displayed greater race time variability, particularly in higher impairment classes, notably KL1. This underscores the existence of distinct developmental stages within the canoe sprint modality, particularly emphasizing the early developmental phase of KL1. It also provides valuable insights for coaches and sports selection, especially concerning athletes with more severe impairments, including those in Rehabilitation Centers and during athlete recruitment.

Costa, Kristine De Martelaer Abstract: Perceptual and Motor Skills, Ahead of Print. In its recent development, the Pictorial Scale of Perceived Water Competence (PSPWC) showed good face and construct validity. However, additional reliability and validity research is needed, including test-retest reliability and a demonstration of the relationship between PSPWEC test scores and actual water competence. Toward that aim, we administered the PSPWC to 124 children, aged 5–8 years. We repeated this test administration after one week for a subset of 55 children to determine its test-retest reliability, and the remaining 69 children also performed the fully aligned Actual Aquatic Skills Test (AAST) in an indoor swimming pool to provide data for our investigation of the relationship between PSPWC scores and actual water competence. We found good test-retest reliability, both at the global level (ICC = 0.81, n = 55) and at the level of individual skills (Weighted kappa coefficients from 0.58 to 0.90), with no significant differences between these two test scores. We also found a moderate positive relationship between PSPWC and AAST total scores (r = .64, n = 69), with no significant difference between total scores of actual and perceived water competencies. Children overestimated their competence in three specific skills: the back star, swimming on the front, and diving in deep water. While these results underline specific situations in which children’s higher self-perceptions of their water competence are a risk factor for their water safety, these data confirm that the PSPWC is reliable for measuring children’s perceived competencies in aquatic education and drowning prevention, and there is further support for its validity through a moderate correlation with actual water competencies.

Authors:Susan M. DeMetropolis, Andrea Pittarello Abstract: Perceptual and Motor Skills, Ahead of Print. Background and PurposeWe examined the allocation of visual attention in an association task by both neurotypical participants (n = 11) and adults with fluent aphasia (n = 12).Research DesignParticipants were presented with a picture (e.g., a basket) followed by a semantically related association (i.e., “strawberry”) and an orthographically related association (i.e., “b,” the first letter of “basket”).AnalysisAn eye tracker recorded their eye movements for three areas of interest (AOI): the picture, the semantic associate, and the orthographic associate, over 1396 observations.ResultsResults showed that both neurotypical participants and participants with aphasia looked longer at the semantic associate than at the picture, and this difference was more pronounced for neurotypicals than for people with aphasia (PWA). Neurotypicals also looked longer than the PWA group at the orthographic associate than at the prior picture. Regarding eye fixation counts, both participant groups looked more frequently at the semantic associate than at either the picture or the orthographic associate. Notably, this pattern was more pronounced among neurotypical participants than PWA.ConclusionsOur findings emphasize the importance of semantic associations in fluent aphasia and suggest a potential rehabilitative approach in speech and language therapy.

Authors:Huma Akram, Shengji Li Abstract: Perceptual and Motor Skills, Ahead of Print. Strengthening online learning outcomes requires the establishment of strong student-teacher relationships to engage students actively in learning activities. Teacher-student relationships are also pivotal factors for enhancing academic motivation for online learning engagement. Generally, however, research on online teaching remains underdeveloped. We aimed, in this study, to investigate the complex interplay in higher education in Pakistan between teacher-student relationships, academic motivation, and online learning engagement. We used Self-Determination Theory to frame an exploration of the impact of positive teacher-student relationships as mediated by intrinsic or extrinsic academic motivation on students’ engagement in online learning activities. We administered a student self-report questionnaire to 437 participants from diverse universities in Sindh province. Using Structural Equation Modeling, we confirmed a model fit in which there were positive correlations between teacher-student relationships and students’ online learning engagement; and between students’ intrinsic and extrinsic academic motivations and their on line learning engagement. Our findings emphasized the need for communication, personalized support, and a sense of belonging in virtual education. Moreover, our findings revealed the mediating role of students’ intrinsic and extrinsic academic motivation in teacher-student relationships, highlighting the nuanced dynamics of academic motivation in the virtual learning environment, with intrinsic motivation having the greatest mediating impact in the relationship between teacher-student relationships and on line learning engagement. Our study’s practical implications include a need for professional educators to foster positive teacher-student relationships and integrate student motivational elements into online course design.

Authors:Guilherme Ribeiro, Rafael Alves De Aguiar, Artur Ferreira Tramontin, Eduardo Crozeta Martins, Fabrizio Caputo Abstract: Perceptual and Motor Skills, Ahead of Print. We investigated fatigue and performance rates as decision-making criteria in pacing control during CrossFit®. Thirteen male regional-level competitors completed conditions of all-out (maximum physical work from beginning to end) and controlled-split (controlled physical work in the first two rounds but maximum work in the third round) pacing throughout the Fight Gone Bad workout separated by one week. We assessed benchmarks, countermovement jumps and ratings of fatigue after each round. Benchmarks were lower in round 1 (99 vs. 114, p < .001) but higher in rounds 2 (98 vs. 80, p < .001) and 3 (97 vs. 80, p < .001) for controlled-split compared with all-out pacing. Reductions in countermovement jumps were higher after rounds 1 (−12.6% vs. 1.6%, p < .001) and 2 (−12.7% vs. −4.0%, p = .014) but similar after round 3 (−13.2% vs. −11.3%, p = .571) for all-out compared with controlled-split pacing. Ratings of fatigue were higher after rounds 1 (7 vs. 5 a.u., p < .001) and 2 (8 vs. 7 a.u, p = .023) but similar after round 3 (9 vs. 9 a.u., p = .737) for all-out compared with controlled-split pacing. During all-out pacing, countermovement jump reductions after round 2 correlated with benchmark drops across rounds 1 and 2 (r = .78, p = .002) and rounds 1 and 3 (r = −.77, p = .002) and with benchmark workout changes between pacing strategies (r = −.58, p = .036), suggesting that the larger the countermovement jump reductions the higher the benchmark drops across rounds and workouts. Therefore, benchmarks, countermovement jumps and ratings of fatigue may assess exercise-induced fatigue as decision-making criteria to improve pacing strategy during workouts performed for as many repetitions as possible.

Authors:Erhan Secer, Derya Ozer Kaya Abstract: Perceptual and Motor Skills, Ahead of Print. A reliable, versatile means of assessing visuo-motor reaction time (V-MRT) is important to football (soccer) players for many reasons, including the fact that faster V-MRT is a critical sport skill that may even play a role in reducing common sports injuries to the lower muscle extremities that can be associated with lost time on the field. We aimed to determine the test-retest reliability and minimum detectable change (MDC) of the Brain Pro System for assessing lower-extremity V-MRT in young male football players. We had 68 participants (M age = 16.35, SD = 1.71 years) perform two assessment sessions one-week apart. For test-retest reliability, we calculated a one-way intra-class correlation coefficient (ICC) at the 95% confidence interval and provided the standard error of measurement (SEM) and minimum detectable change (MDC) (MDC = SEM × 1.96 × √2) for V-MRTs. We obtained excellent V-MRT test-retest reliability for dominant lower-extremity, non-dominant lower-extremity, and dominant and non-dominant lower-extremities (ICC2,1 = .93, 95%CI = .89–.96; ICC2,1 = .94, 95%CI = .91–.96; ICC2,1 = .96, 95%CI = .94–.97; respectively). The calculated MDC for the dominant lower-extremity V-MRT, the non-dominant lower-extremity V-MRT, and dominant and non-dominant lower-extremities (random) V-MRT were 1.21 seconds, 1.13 seconds, and 1.21 seconds, respectively. Brain Pro System had excellent reliability for assessing lower-extremity V-MRT in young male football players. The MDC values at the 95% confidence level (MDC95) we obtained were reliable for assessing clinically meaningful V-MRT changes.

Authors:Sinan Yıldırım, Serap Sarıkaya Abstract: Perceptual and Motor Skills, Ahead of Print. Our primary objective in this study was to psychometrically evaluate the Transformational Parenting Questionnaire (TPQ) within the Turkish context. Secondarily, we aimed to determine whether the questionnaire demonstrated measurement invariance across children’s genders and grade levels. We included 950 participants, aged 11–18 years (446 girls, 498 boys, 6 unspecified gender identity; Mage = 14.73, SD = 1.85 years). Confirmatory factor analysis provided support for the original 4-factor structure of the TPQ, and there was satisfactory criterion-related correlational validity between this instrument and the Satisfaction with Life Scale. The TPQ exhibited robust internal item reliability coefficients, and respondent’s test-retest correlations over a 15-day interval suggested adequate item response consistency. Importantly, we confirmed measurement invariance of the scale across participants gender and educational grade levels. In summary, we found that the TPQ was a valid and reliable tool for assessing Turkish children’s perceptions of transformative parenting behaviors.
