Title: Individual differences in overextinction of the SCR component of the orienting response
Abstract: The present study investigated individual differences in overextinction of the skin conductance response (SCR) component of the orienting response. On the basis of Sokolov's (1963) proposal that overextinction is accompanied by drowsiness, two hypotheses were formulated: (a) subjects exhibiting overextinction will display lower levels of skin conductance and spontaneous activity during the return period than subjects who show no response return, (b) overextinction in the return group will be accompanied by a fall in both skin conductance level and spontaneous activity. Neither of these hypotheses was supported. The results did indicate, however, that the return group displayed slower initial habituation rates and more spontaneous activity than the non-return group. Within the return group, speed of response return was positively related to both spontaneous activity at rest and number of stimuli required for initial habituation, and negatively related to mean SCR latency during initial habituation.
