STUDIES HAVE SHOWN THAT IT IS POSSIBLE TO ESTABLISH DISCRIMINATORY RESPONSES TO PAIRS OF STIMULI WITHOUT ERROR RESPONSES TO THE UNREINFORCED (S-) STIMULUS. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECTS OF 2 METHODS OF INTRODUCING S- (FADING AND CONSTANT) AND 2 RESPONSE CONTINGENCIES (DELAY AND NO DELAY) ON THE OCCURRENCE OF S- RESPONSES.…

Studies with animals indicate that conditioned learning responses formed by non-drugged animals do not transfer to the drug state and vice versa. Authors suggest that state-dependent learning may play casual role in drug abuse. Tested drug list included. (LK)

Study investigated the effects of a response-produced intense-noise stimulus (punishment) on the extinction of children's hitting behavior. (Author)
