Generalization of escape and avoidance responses to stimuli varying in size dimension were investigated using 65 albino rats. Major problems were as follows : (1) Changes in generalization in the process of reinforcement. (2) Changes in generalization in the process of extinction. These changes were observed through absolute generalization, relative generalization, and generalization gradient measured by a response time and the number of extinction trials. The following conclusions were derived from the results obtained from two experiments : (1) Generalization increased as a function of the number of reinforcing trials. (2) Generalization decreased as a function of the number of non-reinforcing trials. (3) All generalization gradients obtained were negatively accelerated, and they decreased as a function of stimulus differences.
