Perceptual Bias in Threat Distance: The Critical Roles of In-Group Support and Target Evaluations in Defensive Threat Regulation

Across two studies, we investigate how perceptions of distances to out-group threats may be critically regulated by the presence or absence of one’s in-group and by beliefs regarding the potential for danger from the out-group. Threat regulation includes biases in the distance one perceives a threat, such that threats are perceived as relatively more distant by more formidable compared to less formidable individuals. We demonstrate that whether participants are alone or surrounded by their ingroup modulates perceptual biases regarding an out-group male’s proximity, depending on the degree to which participants evaluate out-group males negatively. Our findings illustrate how investigations of the psychology of motivated biases may benefit from a consideration of such perceptual biases within the functional workings of defensive threat regulation systems (McNaughton & Corr, 2004) and the strategic logic of animal conflict (Parker, 1974).
