A little boy reverts to the oral comfort of thumb sucking on the way to his first day of school. He is using regression defense mechanism. Regression occurs where a person returns to a child state to escape the present. It is a defense mechanism leading to the temporary or long-term reversion of the ego to an earlier stage of development
The defense mechanism that the little boy is using is regression. Regression, is a defense mechanism that originated from Sigmund Freud’s Psychoanalytic theory, which involves actions of reverting back to an earlier age to repress anxiety such as thumb sucking.
