ELECTRODERMAL AND PLETHYSMOGRAPHIC OR COMPONENTS: REPETITION OF AND CHANGE FROM UCS-CS TRIALS WITH SURROGATE UCS

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.
