Abstract:

For 40 Ss a tone and a light were repeatedly paired P in the same order e.g., tone-light for 15 trials, after which the 2nd member of the pair e.g., light was presented alone as the change trial. For another 40 Ss the repetition consisted of 15 single S tone or light presentations followed by the light or tone as the change trial. The duration of both stimuli and the interstimulus interval on P trials was .3 sec. and .75 sec., respectively, while the mean intertrial interval approximated 45 sec. GSR and digital-blood-volume-pulse-change VPC were recorded. The GSR habituated reliably and at the same rate to both repeated patterns over trials 1-15, but the VPC did not habituate to either pattern. Change from both S and P repetition produced response increases, but the increase under the P condition was not so pronounced as to inspire confidence in explanations of UCS-CS conditioning in terms of OR reinstatement to change.
