• Cognitive psychology is the branch of psychology that focuses on internal states, such as motivation, problem solving, decision-making, thinking and attention. This area of psychology has continued to grow since it emerged in the 1960s.

  Behavioral psychology, also known as behaviorism, is a theory of learning based upon the idea that all behaviors are acquired through conditioning. While this branch of psychology dominated the field during the first part of the twentieth century, it became less prominent during the 1950s. However, behavioral techniques remain a mainstay in therapy, education and many other areas.

  The branch of psychology focused on the study of how the brain influences behavior is often known as biopsychology, although it has also been called physiological psychology, behavioral neuroscience and psychobiology.
