Psychology is the scientific study of the human mind and behavior, exploring how people think, feel, and act in various situations. It encompasses diverse subfields, including clinical psychology (mental health assessment and therapy), cognitive psychology (memory, perception, and problem-solving), developmental psychology (lifespan changes), and social psychology (group behavior and interpersonal relationships). Psychologists employ research methods and evidence-based practices to understand and address mental health disorders, emotional challenges, and behavioral patterns. The field continues to evolve with insights from neuroscience and technology, enhancing therapeutic approaches and our understanding of human nature.
