Psychology is the scientific study of a person's thinking and behavior. It can be divided into more than 25 subdivisions, such as cognitive psychology, behavioral psychology, developmental psychology, social psychology, personality psychology, biological psychology, and clinical psychology. Four of the major subdivisions of psychology include cognitive, behavioral, developmental, and social psychology. Cognitive psychology is the study of the internal processes of the human mind, including how people perceive, think, learn, and remember. This branch of psychology focuses on how people acquire, process, and store information. This type of psychology is the exact opposite of behavioral psychology, which studies measurable and observable behaviors. Two important concepts that accompany behavioral psychology are classical and operant conditioning, both cause learning but the processes are different. Classical conditioning involves learning through the process of association. A good example of classical conditioning would be Ivan Pavlov and his dogs. Pavlov presented his dogs with powdered meat (unconditioned stimulus) which made the dogs salivate (unconditioned response). During conditioning, a bell was presented in front of the meat powder. After doing this for a while, the dogs began to salivate after just hearing the bell. The bell now becomes the conditioned stimulus and the salivation resulting from hearing it becomes the conditioned response. Operant conditioning is a form of learning that occurs through rewards and punishments for a certain behavior. Through this type of conditioning, an association is established between a behavior and a consequence of that behavior. An example of operant conditioning could be the Skinner... in the center of the paper... in this therapy the therapist teaches the patient how to recognize useless thought patterns, how to recognize and modify erroneous beliefs and how to relate to other people in a positive. People with depression, anxiety disorders, bipolar disorder, eating disorders, and schizophrenia are targeted for this type of therapy. Cognitive behavioral therapy helps patients learn how to cope, what triggers their episodes, and how to view events differently. Works CitedFeist, G. J. & Rosenburg, E. L. (2012).
