Abstract
Eight male rats were divided into two groups and run under two conditions. Group 1 (NS) normal lab environment without shock; Group 2 (S) normal lab environment with gradually increasing shock intensity. It was predicted that a decrease in responding would occur for the shock group, but responding would recover to reach a higher level It was also predicted that, after recovery, when noncontingent food was presented to Group 2, Ss would bar-press for shock alone due to their increased arousal requirements. The results of this study substantiate our predictions.
