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.
先前已经表明，距离可以减轻非言语线索（如注视方向、面部表情、性别和姿势）传达威胁的程度。然而，所研究的距离范围仅限于 45 米或以下。理论预测，在距离 100 米以内应该会有影响。本文报告了在距离可达 90 米的情况下性别和姿势传达威胁的强烈程度的研究结果。研究结果表明，非言语线索不再传达威胁的距离范围在 30-90 米之间。
