Compared to other areas of psychology, social cognition is somewhat indifferent to the role played by self-interest. In this paper we present a thesis that self-interest is a prominent factor shaping interpersonal perceptions and attitudes. We review several research lines showing the dominance of moral information in person perception and the dominance of competence-related information in self-perception. This research provides indirect support for the idea that self-interest strongly influences person (and self-) perception processes. We also discuss research showing directly the strong influence of self-interest considerations on interpersonal attitudes and liking as well as on more descriptive perceptions including moral judgments.
This article reviews a program of research on positivity and negativity effects in person perception. The focus is on studies in which perceivers receive information about the positive and negative behaviors of a target person (or group) and then make trait inferences. The research program was initially grounded in a theoretical approach based on trait-behavior relations (Reeder & Brewer, 1979) and then evolved toward a multiple inference model (MIM). According to MIM, perceivers make multiple inferences about the motives and traits of a target person (Reeder et.al., 2004). The rationale underlying this theoretical development is discussed in some detail.
