Regression , according to
psychoanalyst Sigmund Freud, is a
defense mechanism leading to the temporary or long-term reversion of the
ego to an earlier stage of development rather than handling unacceptable impulses in a more adult way. The defense mechanism of regression, in psychoanalytic theory, occurs when an individual's personality reverts to an earlier stage of development, adopting more childish mannerisms. Psychiatrist Joel Gold suggests that careful use of "ARISE" (Adaptive Regression in the service of the Ego) can sometimes yield creative benefits. To the extent that one is handling thoughts and impulses less like an adult, ARISE involves
play, appreciation and primitive pleasures, and imagination.
