Summary : Response pre-exposure, CS pre-exposure and overshadowing in two-way avoidance learning. The three experiments reported in this article analyse signaled two-way avoidance learning in terms of nominal stimulus (CS), contextual cues (SX) and the response-produced stimuli (SRa), and interpret latent inhibition and response-pre-exposure effect in these terms. In experiment I, two groups of rats, one pre-exposed and the other not pre-exposed to the future avoidance response (Ra), are compared. Subjects which were pre-exposed show a better avoidance performance than those which were not pre-exposed. Two hypotheses are suggested. The first assumes that the first phase of the experiment produced latent learning of the positive consequences...
