objective: the present study compares the efficacy of two most commonly used biofeedback relaxation techniques in the treatment of generalized anxiety disorder. method: 45 individuals with generalized anxiety disorder were randomly assigned to three groups (n=15): group i received electromyographic biofeedback relaxation training, group ii received alpha-electroencephalographic biofeedback rela...

The effect of yoga and relaxation changes in psychophysiological parameters in response to the stress of examination in 75 medical students was studied. Initially five parameters (anxiety level, heart rate, blood pressure, galvanic skin resistance and choice reaction time) were recorded, a month before the examination and on the day of examination. Students were then randomly divided into 3 gro...

Abstract The research was conducted with the purpose to study the effect of prayer and meditation on galvanic skin response (GSR). It was hypothesized that there was a significant positive effect of prayer and meditation (Om chanting) on galvanic skin response (GSR). The sample consisted of 20 normal, healthy female participants through purposive sampling. The age group of the sample was 18 to ...

The purpose of our study was to determine the effectiveness of stress balls in reducing the physiological symptoms of stress. We measured changes in heart rate, blood pressure, and skin conductance and compared the differences between an experimental group that received a stress ball (n=15) and a control group that did not receive a stress ball (n=15). Stress was induced by a two minute timed-t...

The purpose of this study was to compare the effects of Benson's relaxation technique (BRT) with Benson's technique augmented with GSR biofeedback (i.e., biofeedback-aided relaxation, BAR) on the psychological stress symptoms of well college students. Seventy-eight normotensive college students were randomly assigned to one of three groups: the BRT group, the BAR group, and a control group. The...

The article discusses the features of using hardware method recording galvanic skin response (GSR) in studies athletes aimed at identifying and developing mental skills self-regulation. purpose empirical study was to research severity self-regulation young hockey players (n=19) compare data GSR with subjective feelings athletes. results present significant discrepancies between indicators diagn...

A feature-matching model to account for the effects of novelty and significance on psychophysiological responsivity is presented. 2 experiments based on a modified version of the Guilty Knowledge Technique were designed to test predictions derived from the proposed model. Results of Experiment 1 demonstrated that electrodermal responsivity to the test stimulus reflected the degree to which the ...

anxiety disorders are the most common reasons for referring to specialized clinics. if the response to stress changed, anxiety can be greatly controlled. the most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words galvanic skin response (gsr) which is dependent on stress level is used; beside this parameter pe...

Previous research has indicated that viewing 3D displays may induce greater visual fatigue than viewing 2D displays. Whether viewing 3D displays can evoke measureable emotional responses, however, is uncertain. In the present study, we examined autonomic nervous system responses in subjects viewing 2D or 3D displays. Autonomic responses were quantified in each subject by heart rate, galvanic sk...
