Figure 4.

Latency to platform during retention training and probe test. Data are shown for rats pretrained in the spatial version of the task (Figure 2), rats pretrained in the cued paradigm (Figure 3), and naïve rats (n = 10). Retention testing took place 24 hours following initial training, and consisted of three hidden training trials. Group differences in performance for trials 1 and 2 show that previous spatial or cue training improves performance one day following training, and that spatial pretraining improves performance better than cue training.
