Sigmund Freud (۱۸۹۴, ۱۸۹۶) noted a number of ego defenses which he refers to throughout his written works.
We use defense mechanisms to protect ourselves from feelings of anxiety or guilt, which arise because we feel threatened, or because our id or superego becomes too demanding. They are not under our conscious control, and are non-voluntaristic.
Ego-defense mechanisms are natural and normal. When they get out of proportion (i.e., used with frequency), neuroses develop, such as anxiety states, phobias, obsessions, or hysteria.
A defence mechanism is an unconscious psychological mechanism that reduces anxiety arising from unacceptable or potentially harmful stimuli.
Defence mechanisms may result in healthy or unhealthy consequences depending on the circumstances and frequency with which the mechanism is used.
