Discoverers of the Galvanic Skin Response

"Galvanic Skin Response and its role in the instrumental detection of deception The GSR (galvanic skin response, or electrodermal activity) channel is considered the most diagnostic recording in polygraph examinations, and the best discriminator between people providing deceptive answers to test questions and non-deceptive subjects."(...

Effect of Prayer and “OM” Meditation in Enhancing Galvanic Skin Response

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 24 years (Mean= 18.7, SD= 1.55). Gender was female and minimum education was graduation. The daily practice time of prayer and meditation session was 30 minutes for one month. Pre- Post data were recorded before and after intervention of prayer and meditation session by using single group pre-post research design. Recordings of galvanic skin response (GSR) were made on a computerized polygraph (Model Physiopac, PP 4, Medicaid Systems, Chandigarh, India) test. The results revealed a significant increase in GSR values as an effect of prayer and meditation which suggested the psychophysiological relaxation. Practicing prayer and meditation increases the galvanic skin response and hence decreases the stress level of the individual. Language: Englis

The Relationship of Skin Conductance to Behavior in a Vigilance Task

The present study is an attempt to measure the correlation between vigilance , as indicated by signal detection, and the galvanic skin response (GSR). The following four dependent variables were measured: (a) Galvanic skin response (continuously recorded, although discrete values were later selected for measurement); (b) ommission errors (where S fails to detect a signal which has occurred); (c) commission errors (or false detections , where S detects a signal which has not in fact occurred); and (d) reaction times to signals. The major purpose of the present study was, in part, to replicate the Ross, Dardano, and Hackman study utilizing more sophisticated equipment and larger number of subjects and, by taking continuous GSR measurements, to more exhaustively test major hypothesis that a relationship exists between the galvanic skin response and vigilance

Preception in the rat: Autonomic response to shock as a function of length of the warning interval.

The autonomic response (galvanic skin response) to a noxious stimulus (shock) is reduced when the stimulus is preceded by a warning signal. The greatest reduction, 53%, was obtaqined with a warning interval of 1 second. Warning also reduces variance of the response over trials, a decrease of over 90% for the optimum 1-second interval

Improved electrode paste provides reliable measurement of galvanic skin response

High-conductivity electrode paste is used in obtaining accurate skin resistance or skin potential measurements. The paste is isotonic to perspiration, is nonirritating and nonsensitizing, and has an extended shelf life

The CDVPlex biometric cinema: sensing physiological responses to emotional stimuli in film

We describe a study conducted to investigate the potential correlations between human subject responses to emotional stimuli in movies, and observed biometric responses. The experimental set-up and procedure are described, including details of the range of sensors used to detect and record observed physiological data (such as heart-rate, galvanic skin response, body temperature and movement). Finally, applications and future analysis of the results of the study are discussed

CONTINUOUS MONITORING OF THE GALVANIC SKIN RESPONSE

poster abstractGalvanic Skin Response (GSR) is an objective measurement of the electrical conductance of the skin. GSR is tightly correlated with peripheral sweat rate, which in turn is associated with many clinical conditions. These conditions include, but are not limited to, menopausal “hot flashes”, diabetic hypoglycemic and hyperglycemic episodes, and various cancers. The objective quantification of GSR can be a valuable clinical tool in evaluating the effectiveness of clinical interventions for these and other conditions. Current methods of monitoring GSR are not well suited to implementation outside of the clinical setting. The goal of this research is to develop a reliable portable device for real-time ambulatory monitoring of GSR. In order to get accurate and consistent readings, electrodes must be attached to the patient with a lasting and non-irritating electrically conductive gel with suitable impedance characteristics. Development of such a device requires consideration of many physiological factors. The distribution and density of sweat glands must be considered to determine a location for the device on the body that will yield measurable GSR without interfering with the patient’s daily activities. We are in the process of evaluating the electrical impedance of electrode and gel combinations presently used in the Carpenter lab. Quantification of the frequency dependent loading profile of the electrode-gel interface will improve the measurement accuracy of the GSR. The ionic composition of sweat and the sweat rate must be evaluated to ensure that the integrity of the interface between the body and the device is maintained throughout the monitoring period. 1Department of Biomedical Engineering, Purdue School of Engineering and Technology, Indiana University-Purdue University Indianapolis, IN 46204 2Center for Enhancing Quality of Life, Indiana University School of Nursing, IUPUI, Indianapolis, IN 4620
