N2 - Two experiments were conducted to test predictions of Conditioned Attention Theory (CAT; Lubow, 1989) in regard to latent inhibition (LI) in humans. In Experiment 1, LI was assessed as a function of relative positions of the preexposed stimulus and masking task stimulus (peripheral vs central). In Experiment 2, LI was assessed as a function of attention-attraction to the preexposed stimulus (no-attraction vs attraction). LI was obtained when attention to the preexposed stimulus was allowed to decline (Experiment 1, peripheral condition; Experiment 2, no-attraction condition), but was precluded when attention to the preexposed stimulus was either maintained or reevoked (Experiment 1, central condition; Experiment 2, attraction condition). The conditions for maintaining and disrupting LI appear to be similar in animals and humans. Implications for understanding attenuated LI in schizophrenics are discussed.
