Paradigms used in behavior training. The place/cue group was trained with the spatial paradigm: a total of 12 visible and 3 hidden training trials, in which the platform remained fixed in the SE (goal) quadrant of the pool, and a probe test was administered 30 minutes following training. The curtain group had 15 visible training trials in which distal cues were hidden, the platform was rotated in the pool and a probe test was given 30 minutes following training. To assess retention on day 2, spatially pretrained, cued pretrained and naïve animals were given 3 hidden training trials in which the platform remained in the SE goal quadrant.
