Description
In view of the subject's reinforcement history during
avoidance training in the traditional vicious circle paradigm,
the author maintained that the stimulus complex changes little
during punished extinction. It was therefore reasoned that
vicious circle running during punished extinction might be
precluded by the presence of a feedback stimulus (FS) that
had been encountered during training only on avoidance trials.
To test this hypothesis, the presence of an FS and CS were
manipulated in both training and extinction to produce a 3 x 3
factorial design. An analysis of running speed revealed
that all groups ran significantly slower on initial extinction
trials than on terminal acquisition trials, an outcome inconsistent
with the literature. In addition, training condition
was found to affect rate of extinction and rate of acquisition,
although not significantly. These trends suggest that the
effects of punished extinction may be attenuated through the
manipulation of discriminative cues.
