Development and learning psychologists such as Rogers, Loevinger, Perry, Kegan and Kolb define it as integrity and transformational impact via creating dialectical relationships between systems. The definition of self-integration emphasizes a person's transformation in epistemology and meaning making (Kegan, 1994; Loevinger, 1976; Perry, 1999; Piaget, 1962; Rogers, 1951). Building on post-conventional constructivist adult development theory (Cook-Greuter, 1999; Johnson, 2000; Kegan, 1994; Lahey, 1986) this is one of the first empirical explorations of self- integration. Drawing from self-concept structure (Higgins, 1987; Linville, 1985),experiential learning (Kolb, 1984) and intentional change (Boyatzis, 2006) theories the relationships between self-complexity, integrative learning and self- integration are explored. This book is based on the Ph.D research of Dr. Akrivou,supervised by Drs. R.E.Boyatzis and D.A.Kolb. This book is useful for social scientists, organizational scholars, change agents, educators and coaches working with micro (intra-personal)level variables for meso (group,relational) and macro (system) level change.
