Although theoretical attention has been devoted to the situational variability of the self-concept, empirical investigations continue to rely on one-shot methodologies. Such efforts assume that data obtained through these methods can be generalized to other situations in the person's life, even to subsequent years or stages in the life course. Self-concept is a structural product of reflexive activity, but it is also susceptible to change as the individual encounters new roles, situations, and life transitions. The data reviewed in this paper suggest that: (i) self-evaluation generally becomes more favorable through the life-span; (ii) self-evaluation is represented by a "moving baseline" from which situational fluctuations emerge; (iii) self-concept is characterized by both stability and change over the life course; and (iv) environmental stability plays an important role in self-concept stability. Several avenues of research are recommended to develop an accurate, meaningful, and testable theory of the self-concept over time.
Article: INTRODUCTIONMost researchers view self-concept as a set of structured self-attitudes that is relatively stable and "characteristic" of an individual. While numerous studies have examined structural dimensions of self-concept, very few have focused on temporal aspects of self-concept, i.e. changes in self-concept from one situation to another, from one relationship to another, or from one year or stage in the life course to the next. As a result, little is known about the social conditions responsible for change and stability in self-concept.This review demonstrates that the dominant structural conceptualization of self-concept and the concomitant failure to study the dynamic, changing, emerging qualities of self-concept, are the products of three related and widespread methodological practices in self-concept research: (i) a preoccupation with one-shot measures of self-esteem, (ii) an overreliance on samples of adolescents and college students, and (iii) the tendency to measure self-esteem in detached classroom and experimental situations.The objective of this paper is to integrate social psychological, sociological, and developmental research on self-concept. I argue that to understand self-concept we must conceptualize it as a moving baseline with fluctuations across situations (Demo 1985) and life stages. This involves recognizing that the self-concept is simultaneously a complex structure and a process, that it is stable, but that it is also dynamic. I also argue that to capture the dynamic qualities of self-concept it is necessary to obtain repeated measurements and to include naturalistic observations. I move now to a brief review of the evidence that self-concept has both structural and processual qualities, recognizing that this evidence corresponds to two general models used by self-concept researchers and that different points of view exist within each model.
THE STRUCTURAL MODELMany researchers and theorists view self-concept as a multifaceted structure of thoughts, att...
