Abstract

Latent inhibition (LI) is defined as poorer associative learning with a previously exposed, irrelevant stimulus than with a non-preexposed, novel stimulus. This study examined how type of within-subject procedure, class of schizotypal symptoms, and gender modulate LI. Two within-subject procedures were examined, one excluding, and one including a masking task. The former yielded a stronger stimulus preexposure effect than the latter. However, the stimulus preexposure effect was attenuated by total schizotypy score in the masked, but not in the non-masked procedure. The results with schizotypy factors (positive and negative symptoms) as well as with schizotypy factors × gender interactions were inconsistent with those of other studies. It was suggested that in addition to LI, interference and novel pop-out effects were also produced by the procedures, particularly in the non-masked condition.
