It has previously been shown that distance mitigates the extent to which non-verbal cues such as direction of eye gaze, facial expression, sex, and posture communicate threat. However, the range of distances investigated has been limited to 45m or less. Theory predicts that there should be effects at distances up to 100 m. This article reports findings on how strongly sex and posture communicate threat at ranges up to 90 m. Results suggest that the distance where non-verbal cues cease to communicate threat is in the range of 30-90 m.
