Seeing her looking at you: acquaintance and variation in the judgment of gaze depth

The acquaintance of subject and looker as well as the depth of gaze affected male subjects' judgments of a female assistant's looking behavior. In a situation ruling out visual interaction, eye-contact gazes were located no more accurately than other gazes. Nevertheless, although gaze depths were not accurately discriminated, gazes deviating vertically and horizontally, to the edge of the head and just beyond the head, were located with some accuracy. The pattern of errors was toward the head and away from the body. Acquaintance produces a stronger bias away from the body, and may produce other interaction-facilitating biases.
