| Abstract: | Latent inhibition refers to attenuated responding to a conditioned stimulus (CS) that was repeatedly presented without reinforcement prior
to the CS-unconditioned stimulus (US) pairings. Using water-deprived rats as subjects, we observed that interpolating task-irrelevant
stimulation between the preexposure and conditioning phases of a latent inhibition procedure attenuated latent inhibition
(Experiments 1A, 1B, and 2). Apparently, interpolated stimulation segments the preexposure and conditioning treatments into
two separate experiences, much in the same way that a change of context would. Consistent with this view, the interpolated
stimulation did not disrupt latent inhibition if it was also presented during both preexposure and conditioning (Experiment
3). We view these results as analogous to those of Escobar, Arcediano, and Miller (2003), who suggested that the difficulty
in observing latent inhibition in human adults is related to the segmentation between preexposure and conditioning caused
by the usual interpolation of instructions in preparations with humans. |
