The effect of stress on stimulus differentiation.

Abstract
Ss learned to criterion either a discrimniation between stimuli with overlapping stimulus elements, or one between nonoverlapping stimuli. Subsequent introduction of stress in the form of electric shock produced a decrement in performance. Most of this decrement was contributed by Ss who learned the discrimination to a relatively low criterion. These and other results are related to theories of differentiation and drive.
