Interpersonal acceptance-rejection theory (IPARTheory) is an evidence-based theory of socialization and lifespan development. It is composed of three subtheories, each of which deals with a separate but interrelated set of issues. IPARTheory’s personality subtheory – which is the most highly developed component of the theory – deals primarily with the pancultural nature and effects of interpersonal acceptance and rejection. Coping subtheory explores the fact that some individuals are better able to cope with experiences of perceived rejection than are other individuals. Finally, IPARTheory’s sociocultural systems subtheory attempts to predict and explain major causes and sociocultural correlates of interpersonal acceptance-rejection worldwide. Empirical evidence overwhelmingly supports the theory’s major postulates and predictions, especially postulates and predictions in personality subtheory. Emerging evidence about the neurobiological and biochemical risks posed for the development, structure, and function of the human brain are beginning to help explain why these postulates and predictions are so consistently confirmed panculturally.
