Behavioral psychology.

Behavioral psychology, also known as behaviourism, is a learning theory that holds that all behaviours are learned through conditioning. While this branch of psychology dominated the field in the early twentieth century, it declined in prominence during the 1950s. Behavioral techniques, on the other hand, remain a mainstay in therapy, education, and a variety of other fields.

To teach or modify behaviours, people frequently use behavioural strategies such as classical conditioning and operant conditioning. A teacher, for example, could use a reward system to teach students how to behave in class. When students perform well, they are awarded gold stars, which can then be redeemed for cash.

Clinical psychology

Clinical psychology is the branch of psychology that deals with the diagnosis and treatment of mental illnesses, abnormal behaviour, and psychiatric disorders. Clinicians are typically employed in private practises, but many also work in community centres or at universities and colleges.

Others work as part of a collaborative team that may include physicians, psychiatrists, and other mental health professionals in hospital settings or mental health clinics.

Personality psychology

Personality psychology is the branch of psychology that studies the thought patterns, feelings, and behaviours that distinguish each individual. Freud's psychoanalytic theory of personality and Erikson's theory of psychosocial development are two classic theories of personality.
