(Mis)Perceiving Sexual Intent: A Mixed-Method Approach Investigating Sexual Overperception Across Diverse Sexual Identities.

Research on perceptions of sexual interest has documented the tendency for men to overperceive sexual interest (i.e., to perceive a social signal as indicating more sexual intent than the actor intended). However, this work has almost exclusively focused upon these dynamics among heterosexual individuals. Thus, the current set of studies aimed to understand how perceptions of sexual interest manifest among lesbian, gay, and bisexual (LGB) women and men. In Study 1 (N = 85), LGB women and men nominated behaviors that signal sexual intent. Using an act nomination approach, LGB women and men tended to nominate behaviors similar to those nominated by heterosexual women and men. In Study 2 (N = 43), gay men reported acts that were representative of their own and other gay men's sexual interest. Consistent with previous work-by comparing perceived self-reported versus others' sexual intent when engaging in specific behaviors-we found no evidence for a sexual overperception bias in gay men, albeit in a small field study. In Study 3 (N = 307), using a gender-by-sexual orientation design, heterosexual and LGB women and men reported previous experiences in which their friendliness was sexually misperceived. Bisexual women were less likely than other groups to report their friendliness being misinterpreted as sexual by other bisexual women and/or lesbians. Additionally, across all genders and sexual orientations, participants reported feelings of indifference, awkwardness and embarrassment when being misperceived. Ultimately, the current studies' results provide broader insight into the nature of sexual overperception among LGB populations.

PsychoBehavioroimmunology: Connecting the Behavioral Immune System to Its Physiological Foundations.

Although infectious disease has posed a significant and persistent threat to human survival and welfare throughout history, only recently have the psychological and behavioral implications of disease threat become a topic of research within the behavioral sciences. This growing body of work has revealed a suite of affective and cognitive processes that motivate the avoidance of disease-causing objects and situations-a cascade of processes loosely conceptualized as a "behavioral immune system (BIS)." Recent BIS research has linked disease threat to a surprisingly broad set of psychological and behavioral phenomena. However, research examining how the BIS is nested within our broader physiology is only beginning to emerge. Here, we review research that has begun to elucidate the physiological foundations of the BIS-at the levels of sensory modalities, cells, and genes. We also discuss the future of this work.
