Description
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.
