Agreeableness is related to social-cognitive, but not social-perceptual, theory of mind

We hypothesise on a number of grounds that the personality dimension of Agreeableness may be associated with inter-individual differences in theory of mind (ToM) functioning. However it is important to distinguish social-perceptual from social-cognitive ToM. Previous findings on ToM in psychopathic individuals, sex differences in ToM and the associations between ToM and social relationships, all suggest that social-cognitive ToM is more likely than social-perceptual ToM to relate to Agreeableness. In separate empirical studies, we find that Agreeableness is substantially correlated with social-cognitive ToM performance, but uncorrelated with social-perceptual ToM performance. We suggest that the propensity or motivation to attend to the mental states of others may be central to the personality dimension of Agreeableness. Copyright (C) 2008 John Wiley & Sons, Ltd.
