A previous study showed that electroconvulsive shock (ECS) does not interact with foot shock intensity; however, ECS-produced retrograde amnesia was not evident on the first test trial following training. The present study decreased the learning trial-ECS interval to 2 sec. and retrograde amnesia was observed but ECS, again, did not interact with foot shock intensity (0.5 and 3.0 ma.).
