During baseline, clicking on a moving circle was reinforced with one point according to a random-interval (RI) 5-s schedule in context A. During the FT phase, one point was delivered every 5 s in context B. In the renewal test phase, the FT 5-s schedule remained, and the background...
Experiment 1 reported the effects of the interaction of a fixed 1 min delivery schedule and body weight, using schedule-induced self-injection paradigm, in the rate of acquisition of methadone and heroin. Eighty-one rats were assigned to 100% and 80% reduced body weight conditions with and wit...
ATTACK BEHAVIOR AS A FUNCTION OF MINIMUM INTER‐FOOD INTERVAL1 Pigeons were exposed to a procedure in which food was presented after a fixed period of time had elapsed, provided no attack against a nearby stuffed pigeon had occurred during the last 15 sec of the period. As the minimum inter...
