Latent inhibition, retarded conditioning to a stimulus that has been previously repeatedly presented without reinforcement, was examined in the toad Bufo arenarum. Partially dehydrated animals were daily trained in a spatial learning task using a visual cue signaling the presence of a pool with water in an open field. Toads of the Pre-exposed group experienced the unreinforced visual cue for 5 sessions before starting training. Subjects in the Control group (with no pre-exposure to the visual cue) needed only 10 sessions to learn the task, while animals in the Pre-exposed group needed 16 sessions (ANOVA, F1,10=80,52, p
