  • Reliability of the Flash Visual Evoked Potential P2: Double-Stimulation
           Study
    • Authors: Kyra E. Wyatt-McElvain; James E. Arruda; Vanessa R. Rainey
      Abstract: The flash visual evoked potential P2 (FVEP-P2) has been identified as a potentially useful clinical, diagnostic tool for Alzheimer’s dementia (AD) and mild cognitive impairment (MCIa) due to its association with cholinergic functioning in the brain. The FVEP-P2 is the second positive component of the VEP waveform elicited by a single strobe flash. Despite finding a selective delay in the latency of the FVEP-P2 in AD and MCIa groups, adequate levels of sensitivity and specificity have not been achieved due to natural group differences and inter-individual variability. In response, Fix and colleagues introduced a novel, double-stimulation paradigm that contained two strobe flashes (i.e., stimulations). The first stimulation served as a visual challenge while the second stimulation produced the recorded FVEP-P2 component. The results of that investigation indicated that the latency of the FVEP-P2 could be used to reliably discriminate between aMCI and healthy controls when the ISI of the double-stimulation condition was 100 ms or higher. Unfortunately, very little is known regarding the psychometric properties of the FVEP-P2 when produced by a double-stimulation condition. Consequently, we assessed the test–retest reliability of the FVEP-P2 latency produced by a single- and twelve double-stimulation conditions in a sample of young, healthy individuals (N = 20). Results indicated that while the FVEP-P2 latencies produced by the single- and double-stimulation paradigm were reliable, the intra-individual variability continued to be too high for the FVEP-P2 latency to be used clinically. Methods of reducing the intra-individual variability are discussed, including the use of monochromatic light.

  • The Relation Between Trait Anger and Impulse Control in Forensic
           Psychiatric Patients: An EEG Study
    • Authors: Marien Lievaart; Frederik M. van der Veen; Jorg Huijding; Johannes E. Hovens; Ingmar H. A. Franken
      Abstract: Inhibitory control is considered to be one of the key factors in explaining individual differences in trait anger and reactive aggression. Yet, only a few studies have assessed electroencephalographic (EEG) activity with respect to response inhibition in high trait anger individuals. The main goal of this study was therefore to investigate whether individual differences in trait anger in forensic psychiatric patients are associated with individual differences in anger-primed inhibitory control using behavioral and electrophysiological measures of response inhibition. Thirty-eight forensic psychiatric patients who had a medium to high risk of recidivism of violent and/or non-violent behaviors performed an affective Go/NoGo task while EEG was recorded. On the behavioral level, we found higher scores on trait anger to be accompanied by lower accuracy on NoGo trials, especially when anger was primed. With respect to the physiological data we found, as expected, a significant inverse relation between trait anger and the error related negativity amplitudes. Contrary to expectation, trait anger was not related to the stimulus-locked event related potentials (i.e., N2/P3). The results of this study support the notion that in a forensic population trait anger is inversely related to impulse control, particularly in hostile contexts. Moreover, our data suggest that higher scores on trait anger are associated with deficits in automatic error-processing which may contribute the continuation of impulsive angry behaviors despite their negative consequences.

  • Neuromodulating Attention and Mind-Wandering Processes with a Single
           Session Real Time EEG
    • Authors: Óscar F. Gonçalves; Sandra Carvalho; Augusto J. Mendes; Jorge Leite; Paulo S. Boggio
      Abstract: Our minds are continuously alternating between external attention (EA) and mind wandering (MW). An appropriate balance between EA and MW is important for promoting efficient perceptual processing, executive functioning, decision-making, auto-biographical memory, and creativity. There is evidence that EA processes are associated with increased activity in high-frequency EEG bands (e.g., SMR), contrasting with the dominance of low-frequency bands during MW (e.g., Theta). The aim of the present study was to test the effects of two distinct single session real-time EEG (rtEEG) protocols (SMR up-training/Theta down-training—SMR⇑Theta⇓; Theta up-training/SMR down-training—Theta⇑SMR⇓) on EA and MW processes. Thirty healthy volunteers were randomly assigned to one of two rtEEG training protocols (SMR⇑Theta⇓; Theta⇑SMR⇓). Before and after the rtEEG training, participants completed the attention network task (ANT) along with several MW measures. Both training protocols were effective in increasing SMR (SMR⇑Theta⇓) and theta (Theta⇑SMR⇓) amplitudes but not in decreasing the amplitude of down-trained bands. There were no significant effects of the rtEEG training in either EA or MW measures. However, there was a significant positive correlation between post-training SMR increases and the use of deliberate MW (rather than spontaneous) strategies. Additionally, for the Theta⇑SMR⇓ protocol, increase in post-training Theta amplitude was significantly associated with a decreased efficiency in the orientation network.

  • EEG Spectral Analysis on OM Mantra Meditation: A Pilot Study
    • Authors: Bhavna P. Harne; A. S. Hiwale
      Abstract: Mantra meditation is easy to practice. “OM” Mantra is the highest sacred symbol in Hinduism. The present study investigated the temporal dynamics of oscillatory changes after OM mantra meditation. Twenty-three naive meditators were asked to perform loud OM chanting for 30 min and the EEG were subsequently recorded with closed eyes before and after it. To obtain new insights into the nature of the EEG after OM chanting, EEG signals were analyzed using spectral domain analysis. Statistical analysis was performed using repeated measures of analysis of variance. It did not reveal any specific band involvement into OM mantra meditation. But significantly increase in theta power was found after meditation when averaged across all brain regions. This is the main effect of OM mantra meditation. However, the theta power showed higher theta amplitude after condition at all regions in comparison to the before condition of meditation. Finding was similar to other studies documenting reduction in cortical arousal during a state of relaxation. The study argues for the potential role of loud ‘OM’ chanting in offering relaxation. It provides a new perspective of meditation to the naive meditators. This information may help to demystify meditation and encourage those considering this as beneficial practice.

  • Resting Heart Rate Variability and the Effects of Biofeedback Intervention
           in Women with Low-Risk Pregnancy and Prenatal Childbirth Fear
    • Authors: Yoshimi Narita; Hitomi Shinohara; Hideya Kodama
      Abstract: Anxiety about labor in women at the end of pregnancy sometimes reaches levels that are clinically concerning. We investigated whether low-risk pregnant women with childbirth fear during the last trimester demonstrate specific findings with regard to resting heart rate variability (HRV) and examined whether HRV biofeedback can reduce this fear and alter resting HRV. We measured the levels of childbirth fear (Wijma delivery expectancy/experience questionnaire, W-DEQ) and resting HRV indexes in 97 low-risk pregnant women in their 32nd–34th week of gestation and advised women with W-DEQ scores of ≥ 66 (n = 40) to practice HRV biofeedback (StressEraser) at home. We then reassessed these measures 3–4 weeks later in the 36th–37th week of gestation regardless of whether the women practiced the method. We found that childbirth fear had no significant effect on resting HRV indexes when the W-DEQ cutoff was conventionally set at ≥ 66. However, women with W-DEQ scores of ≥ 90 (n = 5) had a significantly lower high-frequency power than their counterparts (p = 0.028). The W-DEQ scores reduced significantly in women who performed HRV biofeedback (n = 18, p < 0.001), but there was no change in those who did not perform the method (n = 20). These findings suggested that very high W-DEQ scores (≥ 90), but not the conventional criteria (W-DEQ score ≥ 66), of the fear of childbirth were associated with low parasympathetic activity among low-risk pregnant women and that HRV biofeedback intervention can effectively decrease the fear of childbirth in these women.

  • Characterization of the Sensorimotor Rhythm in 4-Month-Old Infants Born at
           Term and Premature

      Abstract: The sensorimotor rhythm (SMR) is an electroencephalographic rhythm associated with motor and cognitive development observed in the central brain regions during wakefulness in the absence of movement, and it reacts contralaterally to generalized and hemibody movements. The purpose of this work was to characterize the SMR of 4-month-old infants, born either healthy at term or prematurely with periventricular leukomalacia (PVL). Two groups of infants were formed: healthy and premature with PVL. Their electroencephalograms (EEGs) were recorded in four conditions: rest, free movement, right-hand grasping and left-hand grasping, in order to explore general reactivity to free movement and contralateral reactivity in hand-grasping conditions. Associations between SMR, and cognitive and motor performance were analyzed. The healthy infants showed a SMR between 5.47 and 7.03 Hz, with clear contralateral reactivity to free movement and right-hand grasping. However, the premature infants with PVL did not show enough electroencephalographic characteristics to evidence the presence of SMR. Poor performance, characteristic of children with PVL, was related to low-frequency SMR, while good performance was associated with a higher frequency rhythm in the left hemisphere. The presence of SMR in the group of healthy infants could be considered a sign of health at this age. Thus, poor SMR evidence in the EEG of infants with PVL is probably a sign of brain immaturity or brain dysfunction. Our results provide data on infant SMR development that is needed to design neurofeedback protocols for infants with PVL.

  • The More Vivid the Imagination the Better: The Role of the Vividness of
           Imagination in Vasoconstriction Training and Vasodilatation Training
    • Authors: Julia E. Graef; Winfried Rief; Yvonne Nestoriuc; Cornelia Weise
      Pages: 283 - 298
      Abstract: Blood volume pulse biofeedback represents an effective non-pharmacological treatment for migraine. However, the underlying mechanisms of blood volume pulse biofeedback are still unclear. This study investigated the influence of vividness of imagination, private body consciousness, perfectionism, and general self-efficacy on physiological (blood volume pulse amplitude) and psychological (session performance rated by participants and by trainers) success. Changes in skin conductance and skin temperature indicating habituation to training context were examined. Forty-five healthy male participants were randomized to four sessions of vasoconstriction training or vasodilatation training. Hierarchical linear models were estimated. Results showed significant changes of session performance rated by participants (UC = 0.62, p < .05), by trainers (UC = 0.52, p < .001), and skin temperature (UC = 0.01, p < .001) over time. A change of blood volume pulse amplitude could not be observed (UC = −0.01, p = .65). Vividness of imagination was highly important for both psychological achievement ratings (UC participants  = 1.3, p < .001; UC trainers  = 0.29, p < .01). Relations between skin temperature and general self-efficacy or personal standards were small (UC self-efficacy  = 0.002, p < .10; UC personal standards  = 0.002, p < .05). A time × group interaction regarding trainers’ achievement ratings indicated a specific judgement effect. In conclusion, biofeedback trainers should pay attention to their beliefs and participants’ vividness of imagination.

  • Cerebrovascular Hemodynamics During the Practice of Bhramari Pranayama,
           Kapalbhati and Bahir-Kumbhaka: An Exploratory Study
    • Authors: L. Nivethitha; A. Mooventhan; N. K. Manjunath; Lokesh Bathala; Vijay K. Sharma
      Abstract: Various pranayama techniques are known to produce different physiological effects. We evaluated the effect of three-different pranayama techniques on cerebrovascular hemodynamics. Eighteen healthy volunteers with the mean ± standard deviation age of 23.78 ± 2.96 years were performed three-different pranayama techniques: (1) Bhramari, (2) Kapalbhati and (3) Bahir-Kumbhaka in three-different orders. Continuous transcranial Doppler (TCD) monitoring was performed before, during and after the pranayama techniques. TCD parameters such as peak systolic velocity, end diastolic velocity (EDV), mean flow velocity (MFV) and pulsatility index (PI) of right middle cerebral artery were recorded. Practice of Kapalbhati showed significant reductions in EDV and MFV with significant increase in PI while, Bahir-Kumbhaka showed significant increase in EDV and MFV with significant reduction in PI. However, no such significant changes were observed in Bhramari pranayama. Various types of pranayama techniques produce different cerebrovascular hemodynamic changes in healthy volunteers.

  • Pre-performance Physiological State: Heart Rate Variability as a Predictor
           of Shooting Performance
    • Authors: E. Ortega; C. J. K. Wang
      Abstract: Heart rate variability (HRV) is commonly used in sport science for monitoring the physiology of athletes but not as an indicator of physiological state from a psychological perspective. Since HRV is established to be an indicator of emotional responding, it could be an objective means of quantifying an athlete’s subjective physiological state before competition. A total of 61 sport shooters participated in this study, of which 21 were novice shooters, 19 were intermediate shooters, and 21 were advanced level shooters. HRV, self-efficacy, and use of mental skills were assessed before they completed a standard shooting performance task of 40 shots, as in a competition qualifying round. The results showed that HRV was significantly positively correlated with self-efficacy and performance and was a significant predictor of shooting performance. In addition, advanced shooters were found to have significantly lower average heart rate before shooting and used more self-talk, relaxation, imagery, and automaticity compared to novice and intermediate shooters. HRV was found to be useful in identifying the physiological state of an athlete before competing, and as such, coaches and athletes can adopt practical strategies to improve the pre-performance physiological state as a means to optimize performance.

  • Heart Rate Variability Biofeedback Does Not Substitute for Asthma Steroid
           Controller Medication
    • Authors: Paul M. Lehrer; Charles G. Irvin; Shou-En Lu; Anthony Scardella; Beatrix Roehmheld-Hamm; Milisyaris Aviles-Velez; Jessica Graves; Evgeny G. Vaschillo; Bronya Vaschillo; Flavia Hoyte; Harold Nelson; Frederick S. Wamboldt
      Abstract: Despite previous findings of therapeutic effects for heart rate variability biofeedback (HRVB) on asthma, it is not known whether HRVB can substitute either for controller or rescue medication, or whether it affects airway inflammation. Sixty-eight paid volunteer steroid naïve study participants with mild or moderate asthma were given 3 months of HRVB or a comparison condition consisting of EEG alpha biofeedback with relaxing music and relaxed paced breathing (EEG+), in a two-center trial. All participants received a month of intensive asthma education prior to randomization. Both treatment conditions produced similar significant improvements on the methacholine challenge test (MCT), asthma symptoms, and asthma quality of life (AQOL). MCT effects were of similar size to those of enhanced placebo procedures reported elsewhere, and were 65% of those of a course of a high-potency inhaled steroid budesonide given to a sub-group of participants following biofeedback training. Exhaled nitric oxide decreased significantly only in the HRVB group, 81% of the budesonide effect, but with no significant differences between groups. Participants reported becoming more relaxed during practice of both techniques. Administration of albuterol after biofeedback sessions produced a large improvement in pulmonary function test results, indicating that neither treatment normalized pulmonary function as a potent controller medication would have done. Impulse oscillometry showed increased upper airway (vocal cord) resistance during biofeedback periods in both groups. These data suggest that HRVB should not be considered an alternative to asthma controller medications (e.g., inhaled steroids), although both biofeedback conditions produced some beneficial effects, warranting further research, and suggesting potential complementary effects. Various hypotheses are presented to explain why HRVB effects on asthma appeared smaller in this study than in earlier studies. Clinical Trial Registration NCT02766374.

  • Could White Coat Ocular Hypertension Affect to the Accuracy of the
           Diagnosis of Glaucoma' Relationships Between Anxiety and Intraocular
           Pressure in a Simulated Clinical Setting
    • Authors: Jorge Luis Méndez-Ulrich; Antoni Sanz; Albert Feliu-Soler; María Álvarez; Xavier Borràs
      Abstract: Sixty-one healthy subjects participated in a laboratory study carried out in a simulated clinical setting. Anticipatory anxiety-state was assessed at the arrival and immediately after, with no brief phase of adaptation, measurements of intraocular pressure, heart rate, systolic and diastolic blood pressure were collected. At the end of the procedure, anxiety-trait was also assessed. Results suggest that high levels of both anxiety-state and anxiety-trait significantly predicted a clinically relevant increase of intraocular pressure. Anxiety-state mediated the relationship between anxiety-trait and intraocular pressure, which also was found to be related with heart rate but not related to both systolic and diastolic blood pressure. These results suggest a common mechanism of regulation underlying anxiogenic variability found on both intraocular pressure and heart rate. A reduction in parasympathetic activity appears as a possible mechanism underlying to this phenomenon. This anxiety-enhanced intraocular pressure could be considered a phenomenon analogous to white coat hypertension found in the measurement of blood pressure; therefore, it probably should be taken into account in the clinical context to prevent errors in the diagnosis of glaucoma. Further research on cognitive and emotional regulation of intraocular pressure is needed to best characterize this hypothetical phenomenon.

  • No Effects of Successful Bidirectional SMR Feedback Training on Objective
           and Subjective Sleep in Healthy Subjects
    • Authors: Olaf Binsch; Ellen S. Wilschut; Martijn Arns; Charelle Bottenheft; Pierre J. L. Valk; Eric H. G. J. M. Vermetten
      Abstract: There is a growing interest in the application of psychophysiological signals in more applied settings. Unidirectional sensory motor rhythm-training (SMR) has demonstrated consistent effects on sleep. In this study the main aim was to analyze to what extent participants could gain voluntary control over sleep-related parameters and secondarily to assess possible influences of this training on sleep metrics. Bidirectional training of SMR as well as heart rate variability (HRV) was used to assess the feasibility of training these parameters as possible brain computer interfaces (BCI) signals, and assess effects normally associated with unidirectional SMR training such as the influence on objective and subjective sleep parameters. Participants (n = 26) received between 11 and 21 training sessions during 7 weeks in which they received feedback on their personalized threshold for either SMR or HRV activity, for both up- and down regulation. During a pre- and post-test a sleep log was kept and participants used a wrist actigraph. Participants were asked to take an afternoon nap on the first day at the testing facility. During napping, sleep spindles were assessed as well as self-reported sleep measures of the nap. Although the training demonstrated successful learning to increase and decrease SMR and HRV activity, no effects were found of bidirectional training on sleep spindles, actigraphy, sleep diaries, and self-reported sleep quality. As such it is concluded that bidirectional SMR and HRV training can be safely used as a BCI and participants were able to improve their control over physiological signals with bidirectional training, whereas the application of bidirectional SMR and HRV training did not lead to significant changes of sleep quality in this healthy population.

      Abstract: The challenges of research into brain–computer interfaces (BCI) include significant individual differences in learning pace and in the effective operation of BCI devices. The use of neurofeedback training is a popular method of improving the effectiveness BCI operation. The purpose of the present study was to determine to what extent it is possible to improve the effectiveness of operation of sensorimotor rhythm-based brain–computer interfaces (SMR-BCI) by supplementing user training with elements modifying the characteristics of visual feedback. Four experimental groups had training designed to reinforce BCI control by: visual feedback in the form of dummy faces expressing emotions (Group 1); flashing the principal elements of visual feedback (Group 2) and giving both visual feedbacks in one condition (Group 3). The fourth group participated in training with no modifications (Group 4). Training consisted of a series of trials where the subjects directed a ball into a basket located to the right or left side of the screen. In Group 1 a schematic image a face, placed on the controlled object, showed various emotions, depending on the accuracy of control. In Group 2, the cue and targets were flashed with different frequency (4 Hz) than the remaining elements visible on the monitor. Both modifications were also used simultaneously in Group 3. SMR activity during the task was recorded before and after the training. In Group 3 there was a significant improvement in SMR control, compared to subjects in Group 2 and 4 (control). Differences between subjects in Groups 1, 2 and 4 (control) were insignificant. This means that relatively small changes in the training procedure may significantly impact the effectiveness of BCI control. Analysis of behavioural data acquired from all participants at training showed greater effectiveness in directing the object towards the right side of the screen. Subjects with the greatest improvement in SMR control showed a significantly lower difference in the accuracy of rightward and leftward movement than others.

  • Feeling the Insight: Uncovering Somatic Markers of the “aha”
           Experience
    • Authors: Wangbing Shen; Yu Tong; Yuan Yuan; Huijia Zhan; Chang Liu; Jing Luo; Houde Cai
      Abstract: Whether internal insight can be recognized by experiencing (somatic feeling) remains an unexplored problem. This study investigated the issue by examining potential somatic markers of the “aha” experience occurring at the moment of sudden insight. Participants were required to solve a set of compound remote associates (CRA) problems and were simultaneously monitored via electrodermal and cardiovascular recordings. The “aha”-related psychological components and somatic markers were determined by contrasting insightful solutions with non-insightful solutions. Results showed that the “aha” experience was an amalgam entailing positive affects and approached cognition accompanied by a greater mean skin conductance response (mSCR) amplitude and a marginally accelerated heart rate than the “no-aha” one. These results confirm and extend findings of the multidimensionality of the “aha” feeling and offer the first direct evidence of somatic markers, particularly an electrodermal signature of an “aha” feeling, which suggests a sudden insight could likely be experienced by individuals’ external soma.

  • Using EEG Frontal Asymmetry to Predict IT User’s Perceptions Regarding
           Usefulness, Ease of Use and Playfulness
    • Authors: Christos N. Moridis; Vasileios Terzis; Anastasios A. Economides; Anna Karlovasitou; Vasileios E. Karabatakis
      Abstract: Information systems (IS) community is increasingly interested in employing neuroscience tools and methods in order to develop new theories concerning Human–computer interaction (HCI) and further understand IS acceptance models. The new field of NeuroIS has been introduced to address these issues. NeuroIS researchers have proposed encephalography (EEG), among other neuroscience instruments, as a valuable usability metric, when used effectively in appropriately designed experiments. Moreover, numerous researchers have suggested that EEG frontal asymmetry may serve as an important metric of user experience. Based on the aforementioned evidence, this study aims to integrate frontal asymmetry with Technology acceptance model (TAM). Particularly, we assumed that frontal asymmetry might predict users’ perceptions regarding Usefulness and Ease of Use. Furthermore, we hypothesized that frontal asymmetry might also affect (influence) users’ Perceived Playfulness. Specifically, 82 (43 females and 39 males) undergraduate students were chosen to use a Computer-Based Assessment (while being connected to the EEG) in the context of an introductory informatics course. Results confirmed our hypothesis as well as points of theory about Information technology (IT) acceptance variables. This is one of the first studies to suggest that frontal asymmetry could serve as a valuable tool for examining IT acceptance constructs and better understanding HCI.

  • Auditory Event-Related Potentials in the Interictal Phase of Migraine
           Indicate Alterations in Automatic Attention
    • Authors: Jeffrey J. Sable; Toni A. Patrick; Patrick L. Woody; Katelyn R. Baker; Stephanie Allen-Winters; Frank Andrasik
      Abstract: Migraine has been characterized by interictal cortical hyperresponsivity. We compared event-related brain potentials (ERPs) to unattended tone pairs in migraineurs (interictal) versus non-headache controls, with particular interest in attention-related activity (i.e., the N1 component). Electroencephalograms were recorded from 11 interictal migraineurs and 14 headache-free controls while they watched a silent video. Pairs of 50-ms tones with 500-ms inter-tone intervals were presented with inter-pair intervals of 1 or 5 s. P1, N1, P2, and N2 components were analyzed. N1 peak amplitudes were larger in migraineurs than in controls, especially after the 5-s inter-pair interval. However, there was no difference between groups in the attenuation of the N1 (i.e., no interaction). P2 peak amplitudes were larger in migraineurs, but only after the first tone in the pair. The three migraineurs without aura had larger N1s than the eight with aura. Our findings are consistent with interictal hyperresponsivity of cortical generators of these ERPs in migraineurs. However, areas that inhibit the responses with stimulus repetition do not seem to be affected.

  • Respiratory Sinus Arrhythmia in Cognitive Behavioral Therapy for
           Posttraumatic Stress Symptoms in Children: Preliminary Treatment and
           Gender Effects
    • Authors: Rebecca S. Lipschutz; Sarah A. O. Gray; Carl F. Weems; Michael S. Scheeringa
      Abstract: Cognitive behavioral therapy (CBT) is an efficacious treatment for posttraumatic stress disorder (PTSD) symptoms, but the effect of CBT on physiological indicators is largely unknown. Respiratory sinus arrhythmia (RSA) is an established parasympathetic marker of self-regulatory capacity and stress responsivity. The present study tested if and how resting RSA and RSA reactivity changed following treatment among a sample of children (n = 48) who experienced at least one traumatic event and presented with PTSD symptoms. RSA reactivity was measured in response to personalized trauma-related scripts. Results indicated that changes in RSA after treatment were dependent on pretreatment resting levels of RSA, with individuals with high and low pretreatment resting RSA levels appearing to converge over time in both resting RSA and RSA reactivity by the 3-month follow up. Specific to RSA reactivity, a sex difference was evident, as following treatment, females showed less RSA withdrawal whereas males showed more RSA withdrawal. PTSD symptoms were significantly reduced after CBT but symptom change was not associated with pretreatment resting RSA levels. Overall, these results suggest that there may be multiple physiological patterns within children with PTSD and the direction of the physiological changes after CBT may depend on initial differences in resting RSA levels.

  • Biofeedback-Aided Relaxation Training Helps Emotional Disturbances in
           Undergraduate Students Before Examination
    • Authors: Zahra Gholami Tahsini; Shahrokh Makvand Hosseini; Farahnaz Kianersi; Shahrzad Rashn; Elahe Majdara
      Abstract: The main aim of the present research was to determine the effectiveness of biofeedback-aided relaxation training (BFRT) for alleviating symptoms of depression, anxiety, and stress for undergraduate students as they prepared for their final examinations. In a randomized controlled trial design, 29 male and female students, with heightened levels of depression, anxiety and stress scores on the Depression, Anxiety, and Stress Scale, were chosen and randomly assigned to BFRT or a no-treatment control condition. Subjects assigned to BFRT received eight sessions of BFRT spaced over 4 weeks, during which they were trained to decrease electromyography (EMG) and respiration rate (RESP) and to increase skin temperature (TEMP). Data were extracted and analyzed by GLM statistical analysis. Students receiving BFRT revealed significant reductions in symptoms when compared to the untreated controls. Those receiving BFRT also showed significant changes for the three targeted psychophysiological modalities (EMG, RESP, and TEMP). It was concluded that BFRT can be useful for reducing symptoms of emotional disturbance in undergraduate students during a particularly stressful period and that this may, in turn, help promote overall psychological health.
