Human psychology is the scientific study of the mind and behavior. It explores how people think, feel, and act in various situations. Psychologists examine factors such as emotions, cognition, and social interactions to understand how individuals make decisions and respond to their environment. This field encompasses various sub-disciplines, including cognitive psychology, which focuses on mental processes like memory and problem-solving, and developmental psychology, which studies how people grow and change throughout their lives. By understanding these aspects, psychologists aim to improve mental health and enhance well-being in individuals and communities.
