Previous studies suggest that ancient threats capture attention because human beings possess an inborn module shaped by evolution and dedicated to their detection. An alternative account proposes that a key feature predicting whether a stimulus will capture attention is its relevance rather than its ontology. Within this framework, the present research deals with the attentional capture by threats commonly encountered in our urban environment. In two experiments, we investigate the attentional capture by modern threats. In Experiment 1, participants responded to (...) a target preceded by a cue, which was a weapon or a non-threatening stimulus. We found a larger cuing effect with weapons as compared with non-threatening cues. In Experiment 2, modern and ancient threats were pitted against one another as cues to determine which ones preferentially capture attention. Crucially, participants were faster to detect a target preceded by a modern as opposed to an ancient threat, providing initial evidence for a superiority of modern threat. Overall, the present findings appear more consistent with a relevance-based explanation rather than an evolutionary-based explanation of threat detection. (shrink)

Across taxa, strength and size are elementary determinants of relative fighting capacity; in species with complex behavioral repertoires, numerous additional factors also contribute. When many factors must be considered simultaneously, decision-making in agonistic contexts can be facilitated through the use of a summary representation. Size and strength may constitute the dimensions used to form such a representation, such that tactical advantages or liabilities influence the conceptualized size and muscularity of an antagonist. If so, and given the continued importance of physical (...) strength in human male-male conflicts, a man’s own strength will influence his conceptualization of the absolute size and strength of an opponent. In the research reported here, male participants’ chest compression strength was compared with their estimates of the size and muscularity of an unfamiliar potential antagonist, presented either as a supporter of a rival sports team (Study 1, conducted in urban California, and Study 2, conducted in rural Fiji) or as a man armed with a handgun (Study 3, conducted in rural Fiji). Consistent with predictions, composite measures of male participants’ estimates of the size/strength of a potential antagonist were inversely correlated with the participant’s own strength. Therefore, consonant with a history wherein violent intrasexual selection has acted on human males, a man’s own physical strength influences his representations of potential antagonists. (shrink)
