AVOIDANCE LEARNING AS A FUNCTION OF CONDITIONED STIMULUS VARIABLES.
Abstract:
The present report presents data concerned with the effects of varying several parameters of the conditioned stimulus CS on performance of an avoidance response. Findings 1 Differences due to training procedure are of greater importance in determining avoidance of performance than are differences attributable to the direction of change of CS energy. 2 Avoidance response strength is greater if the change in CS energy is greater, irrespective of the rate or direction of the change. 3 In a shuttlebox apparatus, avoidance response strength is greater with a six second CS-US interval than with a three second interval. 4 Some of the parameters of the CS primarily the rate of CS change interact with each other to influence stimulus discriminability.
