Defense Mechanisms: Definition, Types, and Examples

Defense mechanisms are conscious or unconscious mental processes that help ease or avoid anxiety. These reactions can be helpful or harmful depending on the circumstances and frequency of use. Individuals may or may not realize they utilize these methods, many of which occur as responses to trauma, stress, or anger.

What Are Defense Mechanisms?

Defense mechanisms are often unconscious thoughts or behaviors to protect individuals from anxiety. We all use some form of defense mechanism during critical moments when stress is intense or self-esteem is threatened. According to Freudian theory, personality consists of three aspects of mental functioning—the id, ego, and superego.

The Origin of Emotional Defense Mechanisms

Sigmund Freud, the founder of psychoanalysis, first introduced the idea of emotional defense mechanisms as they pertain to the id, ego, and superego. His daughter, Anna Freud, later expanded his ideas to describe ten defense mechanisms. Experts have since introduced additional examples.

The Three Aspects of Personality

• The id: The id is the most primitive part of our personality and drives us to meet our needs or wants regardless of morality or consequences.
• The superego: The superego guides us to act in morally or socially acceptable ways.
• The ego: The ego deals with reality.

Note: Individuals utilize these methods as responses to trauma, stress, or anger to protect themselves from anxiety when self-esteem is threatened.
