Abstract

This essay briefly considers the psychology of radical psychological transformations, sometimes termed 'quantum change', such as religious conversions.

They can occur abruptly, resulting in a restructuring of the entire personality, sometimes in the direction of greater health, or recovery from drug addiction. The author summarizes seven reported aspects of quantum change such as positive shifts of values or attitudes, widening of perspectives, and increases in self discipline
