DescriptionThe present study examined two proposed moderators of meta-accuracy: actors’ personality traits and actors’ perceptions of an interaction situation with partners. I hypothesized actors’ personality traits would affect their levels of meta-accuracy (Hypothesis 1) and that actors’ perceptions of the interaction situation with partners would also affect their levels of meta-accuracy (Hypothesis 2). The study consisted of 59 participants recruited from Rutgers University–Camden. Participants completed the HEXACO-60 personality questionnaire to measure their personality traits. Each participant was paired with another participant they were previously unacquainted with and interacted with them for five minutes. After the interaction, participants completed the HEXACO-60 two more times: the first measured how they thought their partner perceived them and the second measured how they perceived their partner. Participants also completed the DIAMONDS questionnaire to measure their perceptions of the interaction situation. Actors’ levels of conscientiousness significantly moderated their meta-accuracy levels across all personality traits, such that actors low in conscientiousness had stronger meta-accuracy concerning personality traits in general than actors high in conscientiousness. Actors’ perception of the interaction situation regarding negativity significantly moderated their meta-accuracy levels specifically for emotionality, such that actors who perceived the interaction low in negativity had stronger meta-accuracy concerning emotionality. This research extends previous research on meta-accuracy by identifying personality and situational perceptions as moderators of meta-accuracy.
