It's a guy thing: Sex as a moderator of the relationship between social anxiety and perception of interpersonal warmth in initial heterosexual interactions

Social anxiety or the fear of being evaluated by others in social settings has been shown to contribute to impairments in interpersonal functioning. One way in which such impairments may arise is through biased perceptions of others during social interactions. The present study examined how social anxiety relates to the perception of interpersonal warmth from others within a relationship initiation context, and whether this relationship differs in men and women. Participants were 69 men and 69 women, aged 20.62 years on average (SD = 1.97), who identified as heterosexual. After completing a questionnaire pack online, participants engaged in a laboratory-based interaction with a previously unacquainted participant of the other sex. After the interaction, participants reported their perception of their partner's warmth. Results revealed a negative association between men's degree of social anxiety and their perception of their partner's warmth. This association was not found in women. The moderation of sex on the role of social anxiety in interpersonal perceptions may reflect sex differences in social cognitive abilities.
