Electrodermal Activity is electrical activity of the sweat glands in the skin. Tests of electrodermal activity have indicated correlation between skin conductivity and tendency for deviant behavior, aggressiveness and criminal recidivism. Lie detectors or polygraph tests use electrical skin conductivity and heat rate to measure responses to questions. The influence of anxiety on electrodermal activity and responses to distractors. Contrary to classical expectation, anxiety has been repeatedly observed to be associated with reduced electrodermal activity. This could be the result of successful coping. Electrodermal activity, also known as skin conductance, is the property of the human body that causes continuous variation in the electrical characteristics of the skin.
Electrodermal Activity in Young Adults at Genetic
Risk for Affective Disorder

Low electrodermal activity has been proposed as a trait marker for affective disorder. We attempted to determine if low electrodermal activity could be a genetic marker by testing subjects at genetic risk for affective disorder. During task periods high-risk subjects showed significantly greater electrodermal activity that was lateralized to the left hand. Self-rated depression was higher in the high-risk group during task periods.
Electrodermal activity and temperament in
DON C. FOWLES, GRAZYNA KOCHANSKA and KATHLEEN MURRAY. Abstract: To examine poorly understood patterns of young children's electrodermal reactivity and to test the hypothesis that this reactivity reflects individual differences in the behavioral inhibition system (BIS). We recorded skin conductance responses (SCRs) from 92 4-year-old children during a laboratory session that encompassed physiological and psychological stimuli. Physiological stimuli (breaths), moderately loud to loud sounds, and to a lesser extent, stimuli with psychological significance elicited clear SCRs.
Electrodermal Activity in Psychological Research. William Prokasy. Electrodermal Activity in Psychological Research summarizes the methodological problems involved in the application of electrodermal activity as a dependent variable to basic psychophysiological research. Instrumental conditioning of electrodermal activity and the use of electrodermal measures in research on personality and pathological states, such as with schizophrenics, retardates, depressives, psychotherapy, central nervous system damage, anxiety, and introversion-extroversion.

Electrodermal activity is one of the most frequently used psychophysiological evaluations in psychology research.
