Abstract
Five groups of albino rats were trained and extinguished on a manipulandum response in a modified Skinner box. Both learning and extinction were carried out 24 hrs. after food satiation, and the several groups were extinguished after 2,4, 9, 21, and 88 quasi-distributed reinforcements. The relationship of superthreshold reaction potential to number of reinforcements was found by applying a paired-comparison scaling technique to the training reaction latency data of the 88-reinforcement group. The number of reactions to extinction with a 120-sec. criterion was positively related to the number of reinforcements. The curve of best fit by the criterion of least squares representing the relationship of superthreshold reaction potential to number of excitation responses was found to be positive and concave -upward.Keywords
