When people are asked moderately difficult questions, they often avert
their gazes. We report five experiments in which we documented this p
henomenon. They demonstrate that (1) the frequency of gaze aversion is
related to the difficulty of cognitive processing, (2) this behavior
cannot be due solely to demand characteristics or embarrassment, and (
3) the behavior is functional: Averting the gaze improves performance.
We speculate that averting the gaze helps people to disengage from en
vironmental stimulation and thereby enhances the efficiency of cogniti
ve processing directed by nonenvironmental stimulation.
