Abstract
Extinction of a partially reinforced classically conditioned response in the goldfish was studied with equated reinforcements and with equated trials, with constant and with variable CS-US (conditioned stimulus-unconditioned stimulus) intervals, with long and with short runs of nonreinforcement, with balanced and with biased patterns of partial reinforcement, and with 2 different extinction procedures. Only long runs of unreinforced (UR) trials which tended to come early in each training session (UR-bias) gave any indication of increased resistance to extinction following partial reinforcement. Increased resistance, when it did appear, took the form, not of an overall increase in responsiveness, but of an interaction between Treatments and Days or between Treatments and Trials.Keywords
