Abstract
Five groups of seven rats each were subjected to delay periods of 1, 6, 18, 54, or 162 min. between the last trial of shock-escape training and the initial trial of extinction. Median number of trials to extinction was a negatively accelerated decreasing function of length of delay. Increased delay also led to slower starting and running speeds over trials.
