EFFECTS OF INTERPOLATED REST ON FIRST AND SECOND RESPONSES OF CONDITIONED GSR

Employing an 8-sec CS-UCS interval, the effect of a rest interval on the first (1.3 to 5.0 sec after CS onset) and second (5.0 to 9.5 sec after CS onset) responses of the GSR was measured. Two groups of 14 Ss received a series of paired tones (CS) and shocks (UCS). The rest interval effected an increase in first responses and a decrease in second responses. The data were taken as further support for the position that first responses contain a large orienting component, while second responses are produced through increments in associative strength. © 1969, Psychonomic Journals, Inc..
