A series of experiments were conducted on instrumental modification of the Galvanic Skin Response (GSR) in a discrimination procedure where preparatory signals indicated which discriminative stimulus was to occur. When shock avoidance was contingent upon the presence of a response the GSR was enhanced; when shock avoidance was contingent upon the inhibition of a response there was a decrement in reactivity. Heart rate acceleration occurred to Respond stimuli while deceleration occurred to Inhibit stimuli. Various types of cognitive strategies were reported by the subjects from attempts to control attention by attending less to stimuli associated with inhibition to attempts to arouse a response by thinking of exciting events and to inhibit by thinking of calming events. Postexperimental recognition of words tended to be negatively related to magnitude of response. When the verbal stimuli served directly as discriminative stimuli, however, these relationships tended to be reversed.
