Visualization is a therapy in the context of personality development.
Visualization is often used in psychotherapy in the form of introductory exercises or imagination exercises, for example to practice new behavior or to alleviate stressful conditions. A relaxation procedure is often used before such an introduction exercise, since visualizations can be better brought about in a relaxed state. (Stangl, 2018).
