Evolutionary Perspective on Self-Concept: The Effects of Interpersonal Motivations and Inclusionary Status on Spontaneous Self-Descriptions of Communion and Agency.

Evolutionary models suggest that self-concept is a dynamic structure shaped jointly by interpersonal motivations and social challenges. Yet, empirical data assessing this claim are sparse. We examined this question in two studies. In study 1, participants (N = 386) generated spontaneous self-descriptions and filled out questionnaires assessing dominance and affiliation motivations. We found that self-descriptions categorized as communion or agency were associated with affiliation and dominance motivations, respectively. In study 2, participants (N = 360) underwent an inclusionary manipulation (exclusion, inclusion, popularity) and completed self-description and motivation measures. We found that exclusion (compared to inclusion/popularity) enhanced the salience of communion self-descriptions such that participants described themselves using more communion traits. Finally, in the popularity condition (compared to exclusion/inclusion), an enhanced positive association between salience of agency self-descriptions and dominance motivation was found. Our results support evolutionary models suggesting that self-concept organization shapes and is being shaped by social motivations to enhance interpersonal functioning.
