Key Theories in Psychology: Mental Health Nursing: Addressing Psychological Needs in Medical Settings.

Abstract

Psychology is the scientific study of behavior and mental processes, and it encompasses a variety of perspectives. Four major theories—Behavioral, Cognitive, Humanistic, and Psychoanalytic—have significantly influenced the understanding of human behavior. The Behavioral theory, pioneered by figures like B.F. Skinner and John Watson, emphasizes the role of environmental stimuli in shaping behavior through conditioning. Cognitive theory, championed by psychologists such as Jean Piaget and Aaron Beck, focuses on mental processes such as perception, memory, and problem-solving. Humanistic theory, led by Carl Rogers and Abraham Maslow, emphasizes the inherent goodness of individuals and the importance of personal growth and self-actualization. Lastly, Psychoanalytic theory, introduced by Sigmund Freud, delves into the unconscious mind's influence on behavior, proposing that childhood experiences and repressed memories shape personality and behavior. These theories offer unique perspectives and contribute to a holistic understanding of psychological functioning.
