Abstract

Thirty-six rats were used to study the effects of manipulating both the density and response contingency of feedback during the extinction (OE) of discriminated shuttle-box avoidance. Three operant groups had the opportunity to receive response-produced feedback on either 100, 60, or 30 per cent of the extinction trials. Three yoked groups received the' same number and pattern of feedback stimuli as the operant groups, but independently of their own behavior. Significant ordering was obtained between all operant and all yoked groups, and between operant and yoked groups at all three feedback percentage levels. An ordering trend was obtained for the feedback percentage dimension, which was, however, not significant. The results, however, clearly supported the discrimination hypothesis and upheld the importance of response produced stimulus change in the maintenance of avoidance behavior.
