Rats were given a noncontingent footshock followed at various intervals by electroconvulsive shock. Twentyfour hours later they were trained on a non-shock passive avoidance task and tested for retention 72 hours later. When the interval between NCFS and ECS was short the animals showed an amnesia which reduced as the interval was lengthened. An interval of .5 seconds produced the most pronounced amnesia and intervals greater than 10 seconds produced virtually no amnesia. The results were consistent with a state dependent retrieval failure hypothesis.
