Learning Objective
Describe major immature defense mechanisms—blocking, regression, somatization, and introjection—and recognize their clinical relevance.
Immature defenses are less adaptive strategies that distort reality and are often maladaptive, especially in adults. They are commonly seen in adolescents, personality disorders, and stressful situations.
Blocking
Definition: Temporary inability to think or remember; a transient mental “block.”
Examples:
- A student cannot recall an exam fact but remembers it after leaving the room.
- A woman pauses mid-conversation, forgetting what she was saying.
- Forgetting someone’s name during a conversation.
Key point: It often occurs in embarrassing or stressful moments.
Regression
Definition: Reverting to behaviors characteristic of an earlier developmental stage.
Examples:
- A husband uses “baby talk” when he is sick.
- A man assumes the fetal position after trauma.
- A previously toilet-trained child wets the bed after a new sibling is born.
Key point: Childish or primitive behaviors appear under stress or illness.
Somatization
Definition: Psychological conflict is expressed as physical symptoms without an organic cause.
Examples:
- A student gets a headache during an exam.
- A woman feels nauseated before asking someone out.
- A man becomes blind after witnessing a traumatic event.
Key point: Primary mechanism in somatic symptom disorders.
Introjection (Identification)
Definition: Unconsciously adopting the traits, attitudes, or behaviors of others; the opposite of projection.
Examples:
- A resident imitates the attending physician’s style and mannerisms.
- A child scolds a friend using the same words the mother used.
- A teenager copies a rock star’s fashion and behavior.
Key point: Can be used therapeutically in psychotherapy for modeling positive behaviors.
