Restructuring implicational meaning through memory-based imagery: some historical notes.

This paper provides a historical perspective on the recent increase in the clinical application of imagery techniques to restructure systems of implicational meaning that drive emotional distress or self-defeating behaviors. Janet's early application of such techniques was largely ignored except by a few hypnotherapists. Current applications in cognitive therapy were adapted and extended in the early 1980s from Perls' Gestalt therapy methods. Some precursors to Perls are examined, as well as the work of some of those who developed and formulated the integration of his techniques into Beck's cognitive therapy. It is argued that this process amounted to a significant paradigm shift.
