Two experiments investigated the effects of shock (US) sequence and correlation between signals (CSs) and shocks (USs) on contextual fear with conditioned licking suppression preparation. In both experiments, three shocks of differentintensities were presented in fixed or random order. These shocks were correlated or uncorrelated with three different tones in Experiment 1, and with light, tone, and white noise in Experiment 2. In Experiment 1, the basal licking behavior was more suppressed in the groups with random shock sequence than in the groups with fixed shock sequence, regardless of combination of signals with shocks. Whereas in Experiment 2, the basal licking suppression was greater when signals and shocks were uncorrelated than when they were correlated, regardless of shock sequence. These results suggest that the factor to attenuate contextual fear assessed by licking suppression varies depending on the degree of distinctiveness among signals.

With a conditional matching-to-sample task including selective sample cue of sequential color stimuli, 9 pigeons were trained to respond to the left / right key corresponding to the sample cue. Experiments were conducted for three groups of pigeons. The temporal location of the sample cue in sequential stimuli was varied across the groups. Pigeons of the Group F were trained with the task, in which the first stimulus of the sequential stimuli was the cue for their correct responses. Pigeons of Group C were trained with the task, in which the second stimulus of the sequential stimuli was the cue for their correct responses. Pigeons of Group E were trained with the task, in which the third (end) stimulus of the sequential stimuli was the cue for their correct responses. The best performance was obtained in the Group E, with the average performance in Group F. In contrast, Group C did not show such a good performance. These results suggest that pigeons can selectively use a sample cue of the sequential stimuli based on its temporal location and that it is difficult for pigeons to use the middle sample cue of sequential stimuli.
