Developmental counseling is a promising model integrating theory and practice. A. E. Ivey's (2000; A. E. Ivey & O. F. Goncalves, 1988) work is discussed as a template for proposing a more comprehensive developmental perspective. Where A. E. Ivey's model renders a case for cognition, the current article encompasses other developmental systems driving cognitive processes, such as attachment, self, and affect. A developmental systems theory is advanced as one possible solution to the limitations of available models. Application to case vignettes and a rethinking of "style shift" are offered.
