Visual attention is not attuned to non-human animal targets' pathogenicity: an evolutionary mismatch perspective.

A considerable amount of research has revealed that there exists an evolutionary mismatch between ancestral environments and conditions following the rise of agriculture regarding the contact between humans and animal reservoirs of infectious diseases. Based on this evolutionary mismatch framework, we examined whether visual attention exhibits adaptive attunement toward animal targets' pathogenicity. Consistent with our predictions, faces bearing heuristic infection cues held attention to a greater extent than did animal vectors of zoonotic infectious diseases. Moreover, the results indicated that attention showed a specialized vigilance toward processing facial cues connoting the presence of infectious diseases, whereas it was allocated comparably between animal disease vectors and disease-irrelevant animals. On the other hand, the pathogen salience manipulation employed to amplify the participants' contextual-level anti-pathogen motives did not moderate the selective allocation of attentional resources. The fact that visual attention seems poorly equipped to detect and encode animals' zoonotic transmission risk supports the idea that our evolved disease avoidance mechanisms might have limited effectiveness in combating global outbreaks originating from zoonotic emerging infectious diseases.

Social Categorization of Sexual Orientation via Verbal Cues: Evidence From a "Who Said What?" Study.

Even though an abundant amount of research has demonstrated the ability to identify others' sexual orientation via minimal nonverbal cues, few studies, if any, have investigated the role of verbal information sources on the social cognition of sexual orientation. Herein, we aimed to explore whether verbal cues (gendered names) are adequate for triggering social categorization processes. Additionally, whether participant gender, target gender, and attributions toward homosexual targets differentiate sexual orientation-based categorization was examined. Our data showed that (1) participants categorized targets based on sexual orientation via semantic information, (2) female participants' categorization tendencies were marginally stronger than the males', and (3) negative attributions toward homosexual targets did not influence the categorization levels. Accordingly, the results contribute to the existing literature indicating the automatic detection of sexual orientation and clarify that perceivers not only use numerous nonverbal sources to extract categorical information about sexual orientation but also verbal cues.
