Psychology is the scientific study of the mind and behavior: how people think, feel, learn, remember, decide, relate to one another, and change over a lifetime. It is both a research science and a helping profession. Researchers test ideas about attention, memory, personality, emotion and development against evidence, and clinicians, counselors and therapists apply that evidence to anxiety, depression, trauma, relationships and the ordinary problems of a life.
The field has many branches. Clinical and counseling psychology cover mental health and therapy. Personality psychology asks why people differ in lasting ways, from the Big Five, the field's main trait model, to the popular typologies people meet online, like attachment styles and the 16 personality types. Cognitive psychology studies thinking, memory and the biases that bend judgment. Developmental, social, educational and organizational psychology look at how we grow, how groups shape us, how we learn and how we work.
