The study of human behavior is known as psychology. It is a multifaceted discipline that explores the intricacies of human thought, emotion, and action, encompassing various aspects like cognition, social interactions, and mental processes. Psychologists employ diverse methodologies, from experiments and observations to surveys and case studies, to understand how individuals and groups think, feel, and behave under different circumstances. This field intersects with other disciplines such as sociology, neuroscience, and education, leading to insights that can improve mental health, enhance learning, and foster interpersonal relationships. Ultimately, psychology aims to decode the complexities of human nature to promote well-being and social harmony.
