dc.description.abstract Measures the effect of opportunity for aggression on resistance to extinction. In Experiment 1 pigeons were trained on FR10, FR20, FR40 and FR80 schedules holding number of reinforcements constant for all Ss. Extinction session one indicated large increments in resistance to extinction up to acquisition values of FR40, but little apparent effect of FR values above this figure. A second extinction session showed only small differences in resistance to extinction across schedules. Experiment 2 aimed at measuring the degree of aversiveness experienced by pigeons as a function of FR20, FR40 and FR80. During acquisition and extinction Ss were given the opportunity to attack a restrained target pigeon. Results indicated that more attack occurred the higher the response requirement, both in acquisition and extinction. In Experiment 3 Ss were trained on FR20 and FR80 in the presence of two key colours. A target pigeon was present during one colour and absent during another, response requirement being held constant. A forty minute extinction was divided into ten minute segments during which the target bird was either present or absent. Results showed that opportunity for aggression did not affect resistance to extinction after FR20 but enhanced it after FR80. en
