The ego defense mechanism in which a person who is confronted with anxiety returns to a more immature behavioral stage is called regression.
Explanation:
Regression refers to the process of unconsciously returning to the earlier stage of life. This works as a defense mechanism. Childhood behaviors are portrayed by the individual when he gets threatened or arrives in any problematic situations. They find an escape to those days in which they were aware of such problems and situations.
During a spring-break trip to Mexico, Celeste drank too much tequila, became sick to her stomach, and developed a strong aversion to tequila. This aversion can probably be eliminated by repeatedly drinking tequila, which would be an example of extinction.
