s Abstract Interdependence theory presents a logical analysis of the structure of interpersonal situations, offering a conceptual framework in which interdependence situations can be analyzed in terms of six dimensions. Specific situations present specific problems and opportunities, logically implying the relevance of specific motives and permitting their expression. Via the concept of transformation, the theory explains how interaction is shaped by broader considerations such as long-term goals and concern for a partner's welfare. The theory illuminates our understanding of social-cognitive processes that are of longstanding interest to psychologists such as cognition and affect, attribution, and self-presentation. The theory also explains adaptation to repeatedly encountered interdependence patterns, as well as the embodiment of such adaptations in interpersonal dispositions, relationship-specific motives, and social norms.

INTRODUCTIONThe essence of a social psychological way of thinking frequently is described in terms of the "power of the situation." Indeed, the familiar equation B = f (P, E) embodies our shared desire to understand the ways in which behavior (B) is shaped not only by properties of the person (P), but also by features of the situation, or social environment (E) (Lewin 1936). Perhaps the essence of a social psychological analysis can be even more fully expressed by construing our goals in terms of the relationships between people. To develop a truly social psychology, we may need to expand our formulation, noting that an interaction (I) between persons A and B can be conceptualized in terms of their needs, thoughts, and motives in relation to one another (A and B) in the context of the specific social situation (S) in which their interaction transpires (Holmes 2002, Kelley et al. 2002. Expressed in an equation, I = f (S, A, B).To illustrate the utility of an interaction-based analysis, imagine two scenarios for John and Mary, who are deciding where to spend their summer vacation. In one scenario their interests conflict: John wants to go to a beach resort, whereas Mary wants to go to Rome. In this type of situation each person will seek to explain his or her preference ("I need the excitement of Rome") and each will engage in cognitive activity oriented toward understanding the other's needs ("Does John want to relax because he had a stressful year?"). The situation makes it possible for each person to display his or her goals and motives (self-centered vs. prosocial). Communication and information-seeking will center on each person's needs, goals, and motives in relation to those of the partner ("Whose needs are more pressing?" "Will Mary be responsive to my needs?"). The two may rely on fairness norms to resolve their problem ("It's my turn" or "You deserve a break"). Thus, situations involving conflicting interests are interpersonally rich, affording psychological processes such as self-presentation and attributional activity and activating morality-an...
