Using lick suppression by water-deprived rats as an associative index, white noise-footshock pairings resulted in less manifest conditioning when repeated non-reinforced presentations of the white noise preceded conditioning than when no stimulus pre-exposure was given, i.e., latent inhibition was observed. However, the latent inhibition deficit was reduced in animals who received as a reminder treatment shock-alone presentations in another context during the retention interval. Animals conditioned without prior stimulus pre-exposure and those exposed to the white noise and shock unpaired during the conditioning phase of the study showed no change in lick suppression as a result of the reminder treatment. These results suggest that the behavioural deficit produced by non-reinforced pre-exposure to the to-be-conditioned stimulus arises at least in part from a reversible retrieval failure rather than a lack of acquisition. 相似文献
