Abstract
Six groups of rats received either 18 or 96 reinforcements delivered either at the bar, 2 in. from the bar, or 4 in. from the bar. Ss rewarded at the bar extinguished significantly faster after 96 than 18 reinforcements. The converse was true for the other two bar locations. Results were discussed in terms of frustration theory.
