Transformation, used in psychology (and New Age thought), refers to a major change or shift in an individual's thought and/or behavior patterns. This type of change normally requires a major change in thought patterns and values.
For instance, an individual who suddenly gives up a non-religious lifestyle to become highly religious can be said to have undergone a spiritual transformation. Piaget used the term transformation to refer to any type of change that an individual could experience. In psychoanalysis transformation is when unconscious ideas or desires are disguised so that they may become acknowledged by the conscious.
