Protection from extinction of conditioned fear has been demonstrated when a conditioned inhibitor of fear is presented during extinction treatment. The present study assessed if similar results could be obtained during the analogous habituation of unconditioned fear. The neophobic response typically elicited by the presentation of a novel flavor was used as a model of unconditioned fear. Consumption by rats was used to ascertain the impact of nonreinforced exposure to a novel flavor either alone, in compound with another novel flavor, or in compound with a safe flavor (i.e., a flavor previously trained as a conditioned inhibitor for illness). The presentation of the novel flavor alone in the absence of illness reduced neophobia. However, exposure to the novel flavor in compound with the safe flavor reduced habituation of neophobia. This effect was not observed when the novel flavor was exposed in compound with another novel flavor. These results suggest that removing safe stimuli from the therapeutical environment might improve the effectiveness of exposure therapy in the treatment of unconditioned fear. |
