These are psychological strategies employed, often unconsciously, to protect oneself from unacceptable thoughts, feelings, or impulses. They serve to reduce anxiety and maintain a positive self-image when faced with internal or external stressors. For example, a student who consistently performs poorly on exams might employ rationalization, attributing their failures to unfair testing methods rather than acknowledging a lack of preparation.
The utilization of these mechanisms is essential for psychological well-being as they provide a buffer against emotional distress. However, an over-reliance on such strategies can lead to distorted perceptions of reality and hinder personal growth. The concept originated within psychodynamic theory, particularly through the work of Sigmund Freud and later expanded upon by his daughter, Anna Freud, shaping the understanding of human behavior and mental health.
