It has been found that nonreinforced pre-exposure to the to-be-conditioned stimulus results in a decrement in performance during the acquisition phase of a classical defensive leg response conditioning procedure. The present study shows that: (a) this decrement is a function of the frequency of pre-exposure, (b) the size of the decrement remains constant over 4 days of acquisition training, and (c) the decrement as a function of pre-exposure is not significant during extinction.
