This first volume of two in the revised and greatly expanded edition of Professor Wylie's now classic work describes and evaluates measurement methods, research designs, and procedures which have been or might appropriately be used in self-concept research. Offering comprehensive treatment of the voluminous recent literature in the field, it constitutes a unique and invaluable guide to scholars and students of self theories and self-concept research. Many of the methodological issues considered here also have broader relevance for personality research and theory.

The concept of the Self has a long history that dates back from the ancient Greeks such as Aristotle to more contemporary thinkers such as Wundt, James, Mead, Cooley, Freud, Rogers, and Erikson (Tesser & Felson, 2000). Research on the Self relates to a range of phenomena including self-esteem, self-concept, self-protection, self-verification, self-awareness, identity, self-efficacy, self-determination etc. that could be sharply different or very similar. Despite this long tradition of thinkers and the numerous studies conducted on the Self, this concept is still not very well defined. More precisely, it is not a precise object of study, but rather a collection of loosely related subtopics (Baumesiter, 1998). Also, in the philosophical literature, the legitimacy of the concept of “self” has been brought into question. Some authors have argued that the self is not a psychological entity per se, but rather an illusion created by the complex interplay between cognitive and neurological subsystems (Zahavi, 2005). Although no definitive consensus has been reached regarding the Self, we emphasis in this volume that the Self and its related phenomena including self-concept, motivation, and identity are crucial for understanding consciousness and therefore important to understand human behavior. Self-concept, motivation and identity: Underpinning success with research and practice provides thus a unique insight into self-concept and its relationship to motivation and identity from varied theoretical and empirical perspectives. This volume is intended to develop both theoretical and methodological ideas and to present empirical evidence demonstrating the importance of theory and research to effective practice.

Written by leading researchers in educational and social psychology, learning science, and neuroscience, this edited volume is suitable for a wide-academic readership. It gives definitions of key terms related to motivation and learning alongside developed explanations of significant findings in the field. It also presents cohesive descriptions concerning how motivation relates to learning, and produces a novel and insightful combination of issues and findings from studies of motivation and/or learning across the authors' collective range of scientific fields. The authors provide a variety of perspectives on motivational constructs and their measurement, which can be used by multiple and distinct scientific communities, both basic and applied.

Research on the self relates to various phenomena including self-esteem, self-concept, self-verification, self-awareness, identity, self-efficacy, passion, self-determination, and goals. Moreover, research on self is multidisciplinary and of interest to a broad range of areas, such as education, economics, (social) psychology, neuro sciences, motivation, physical activity and behavior sciences, philosophy, and learning sciences. Chapters in this volume will illustrate some of the best of the research within these disciplines examining different aspects of self from various perspectives. A feature of this volume is that we will explore not only positive aspects of high perceived levels of self-determination and competence or self-concept on achievement, motivation and wellbeing, but also the dark side of an uncertain and negative self on identity and wellbeing. We learn from this that the self is a dynamic and powerful, yet fragile and highly amenable construct that needs self-care and constant reassurance. SELF – A Multidisciplinary Concept thus highlights the broad application of self-research and its diversity. This volume is intended to develop both theoretical and methodological ideas and to present empirical evidence of various disciplines and applications dealing with self. The scope of this seventh volume of the International Advances in Self Research series, started in 2000 by Herbert W. Marsh, Dennis M. McInerney, and Rhonda G. Craven, is thus very broad. Keeping within the tradition of the series, this volume will highlight the applicability of a multitude of empirical approaches and methods to self-research. We also aimed to maintain a balance between discussing theoretical research in SELF and deriving implications for effective practice. This volume thus includes chapters covering self-related topics within an educational, social, emotional, psychological, physiological, managerial, and health context.

[This book provides a] review of self-concept measures that can be used with individuals across the life span, from preschool through late adulthood. These measures were selected according to the prevalence of their use in research and practice, their psychometric soundness, the strength of their theoretical base, and their demonstrable utility in a variety of research and practice situations. For each measure there is a description of the instrument, the target population, the scale structure, administration and scoring procedures, normative data, and related psychometric research, as well as an evaluative summary and source information. Byrne also provides a comprehensive review of the literature related to 7 empirically testable models of self-concept. Finally, the author identifies the most important psychometric issues related to measuring self-concept, describes the limitations associated with the current state of self-concept measurement, and points to promising directions for future research and application.
