| Abstract: | Studied retention of events occurring on a just-preceding trial in 32 male albino Wistar rats using a delayed-alternation procedure in which Ss were trained to alternate to criterion and then were tested for retention at delays of 0, 5, 15, and 30 sec. 4 groups were tested under different cueing conditions by factorially combining 2 conditions of spatial separation cues adjacent vs. cues apart, with 2 conditions of visual differentiation cues identical in brightness vs. cues different in brightness. Both placing cues apart and visually distinguishing cues enhanced performance on retention tests. Analyses indicate that spatial separation influenced performance by establishing different levels of initial trace acquisition, whereas visual differentiation influenced performance by producing different rates of forgetting.
