Rats received a shock to the feet when they stepped off a raised platform. Immediately after such an experience, half of the Ss received a single ECS. When tested 24 hr. later, the percentage of Ss that left the platform was significantly greater in the ECS group than in the control group. "The results . . . lend support to the hypothesis that ECS interferes with memory and are in opposition to the hypothesis that ECS affects performance by inducing fear."
