Assertion: Regression can occur when a person's resolution of problems at any stage of development is inadequate.
Reason: Fixation refers to displaying behaviors typical of a less mature stage of development.
Answer & explanation
Correct answer: option 3
Freud's assertion that regression can occur when resolution of problems at any stage of development is inadequate is true. Regression (not Fixation) refers to reverting to behaviors characteristic of an earlier stage of development. When individuals do not adequately resolve conflicts at a particular stage, they may exhibit behaviors associated with a less mature stage as a way of coping or dealing with unresolved issues.
