Stimulus control of skin resistance responses on an escape-avoidance schedule

The effects of discrimination and avoidance training on the skin resistance response were studied in eight humans. Responses occurring during one stimulus delayed the interruption of music for 30 sec; responses during a second stimulus either had no effect or interrupted the music for 15 sec. The results showed stimulus control in all subjects and an increased discrimination between the first one-half and last one-half of the sessions for seven of the eight subjects.
