Extinction of avoidance as a function of the escape situation

In a factorial design, 20 rats “were trained and extinguished under two different conditions: (a) when the escape area was a box similar to the box to be avoided, and (b) when the escape area was an open platform and quite dissimilar to the shock box …. Entering an escape area similar to the shock box clearly facilitated extinction of the avoidance response but had no significant effect on the mean number of trials to reach the acquisition criterion …. Resistance to extinction was also found to be an inverse function of the number of seconds of shock received during acquisition, as determined by each S's own escape time.” From Psyc Abstracts 36:01:1EK12D.
