Abstract
Frontal operated, operated and nonoperated control Ss were tested with an 8 sec. delay of reward on a visual discrimination task. Frontal operated Ss showed greater impairment in performance than the other groups. The impairment persisted at all delays but disappeared when the delay was eliminated. The frontal Ss also showed impairment on a single alternation test. The mechanisms for bridging time intervals are discussed and caution is urged in interpreting results from frontal animals.Keywords
