Which scenario best illustrates regression in a psychoanalytic context?

Regression is a defense mechanism identified in psychoanalytic theory, where an individual reverts to behaviors characteristic of an earlier developmental stage in response to stress or anxiety. It often manifests as a return to comforting behaviors or habits from childhood.

The scenario that best illustrates regression is the one where the medical student watches cartoons and clings to a teddy bear after being expelled. This behavior reflects a retreat to a childlike state as a way to cope with emotional distress. Watching cartoons and holding onto a teddy bear are activities typically associated with childhood, indicating the student is seeking comfort and familiarity in a time of upheaval.

By engaging in these behaviors, the medical student is avoiding confronting the harsh realities of adulthood and the consequences of expulsion. This clearly aligns with the concept of regression, as it shows a regression to a simpler time when such responsibilities and stressors did not exist.
