Abstract
The growing field of clinical‐developmental psychology has been influenced by Lawrence Kohlberg's theory of moral judgement. Too literal a use of structural theory, however, has hindered this field's advancement. This paper argues that a new theory of self is required to apply appropriately developmental theory to clinical practice. The model consists of two related dimensions of self: self‐complexity and biographical themes (schemata and themata). A perspective on normal and atypical development given by the interactions between these components is described and implications for practice are discussed.
