Which defense mechanism involves dealing with feelings by acting childlike?

Regression is a defense mechanism where an individual reverts to behaviors characteristic of an earlier stage of development when faced with stress or anxiety. This childlike behavior serves as a way to cope with overwhelming feelings by avoiding the pressures of adult responsibilities and conflicts. For instance, an adult may throw a tantrum or start to engage in childlike activities, such as coloring or playing games, in response to stressful life events.

This mechanism allows for temporary relief from discomfort and can provide a sense of safety and comfort, similar to how a child might seek solace in familiar and simple activities during difficult times. The return to earlier behaviors can signify an attempt to escape from the complexities and difficulties of adult life, highlighting a desire to return to a more secure and uncomplicated state.

While other defense mechanisms like repression, reaction formation, and displacement involve different coping strategies, none of them specifically focus on the childlike regression to manage feelings or stress.
