Abstract

Rats were trained in a passive avoidance task. Twenty-four hours later they were given a noncontingent footshock (FS) followed by electroconvulsive shock (ECS). ECS followed FS by different intervals ranging from .5 to 300 seconds in different groups. Subjects were tested 24 and 96 hours after the FS-ECS treatments for retention of the avoidance response. There were no statistical differences between the groups. This finding could not be taken as evidence that FS-ECS failed to produce amnesia since no evidence of passive avoidance conditioning in trained subjects not receiving FS-ECS.
