Abstract
This study investigated the interaction between drive level and original and generalized stimulus conditions during extinction. One hundred Ss were first conditioned for 80 trials to respond to a .6-psi air puff on an 80% reinforcement schedule with a CS of 1500 cps. The Ss were then divided into four groups which were extinguished with either a 1500- or 400-cps tone and a .33- or 2.0-psi air puff. On all nonreinforced trials during acquisition and extinction the UCS was presented, but 2500 msec. after the CS. The results confirmed (P<.05 for Extinction Trials 1-40) the hypothesized interaction between drive level and original and generalized stimulus conditions predicted by Hull-Spence theory. The effect was not significant over Trials 1-10 or 1-20.Keywords
