The core social psychology faculty members at USC conduct research on five broad topics:

Social Cognition. Research on social cognition strives to understand the cognitive processes that underlie social behavior. This work includes specific topics such as impression formation and empathy (Leor Hackel), causal reasoning, person perception, and attribution (Steve Read, Norbert Schwarz, Daphna Oyserman), the role of social circle perceptions in voting and health behavior (Wändi Bruine de Bruin), cognitive dissonance and attitude change (Steve Read, Norbert Schwarz), social categorization and stereotyping (Daphna Oyserman, Steve Read, Norbert Schwarz, Wendy Wood), the role of feelings and bodily sensations in social judgment (Norbert Schwarz, Daphna Oyserman), effects of culture in reasoning (Daphna Oyserman), culture and identity as situated cognition (Daphna Oyserman), habits (Wendy Wood), and automaticity in behavior (Wendy Wood).

Motivation and Emotion. Motivation and emotional processes play an important role in social behavior. Research on motivation and emotion conducted by social psychologists at USC includes work on self-regulation (John Monterosso, Daphna Oyserman, Wendy Wood), motivational structures of ideological and moral convictions (Steve Read), group memberships such as gender as a basis for identity and motivation (Daphna Oyserman), and developing computational models of social behavior, personality, motivation and affective processes (Leor Hackel, Morteza Dehghani, Steve Read, Lynn Miller).

Judgment and Decision-making. People’s decisions about social, health-related, environmental, and economic issues occur in a social context. Social psychology provides important insights into how people make judgments and decisions about risks and opportunities, and how interventions may inform their judgments and decisions. Members of the area study such topics asthe interplay of feeling and thinking in judgment and decision making (Norbert Schwarz, Wändi Bruine de Bruin, Joe Árvai), prosocial decisions and reinforcement learning in social interaction (Leor Hackel), individual differences in decision-making competence (Wändi Bruine de Bruin, Joe Árvai), how people form their perceptions of risk, and how those risk perceptions and social context inform their decisions (Joe Árvai, Wändi Bruine de Bruin), and legal, moral and everyday decision making (Morteza Dehghani, Steve Read, Lynn Miller, John Monterosso, Norbert Schwarz, Daphna Oyserman, Joe Árvai, Wändi Bruine de Bruin).

Interpersonal Relationships. Social relationships between individuals form the basis for much social behavior. Understanding the psychological bases of interpersonal behavior is a major goal of social psychologists. Specific areas of research on interpersonal relationships at USC include work on attraction and attachment in romantic relationships (Lynn Miller, Steve Read), social partner choice (Leor Hackel), and decision-making and interpersonal negotiation in risky sexual behavior (Lynn Miller, Steve Read).

Intergroup Relations. Groups are centrally important for regulating human behavior, and relations between human groups are often antagonistic. Researchers at USC are investigating the cognitive and affective mechanisms that underlie political and religious ideologies as they affect intergroup behavior (Morteza Dehghani, Daphna Oyserman), and learning about social groups (Leor Hackel, Wendy Wood).
