The assignment content discusses operant and classical conditioning theories in psychology. Operant conditioning is a type of learning that involves voluntary behavior, developed by B.F. Skinner, while classical conditioning is a type of learning that involves involuntary responses, developed by Ivan Pavlov. The two main components of operant conditioning are reward and punishment, whereas the component of classical conditioning is stimuli and response. The main differences between operant and classical conditioning theories include the voluntary vs. involuntary nature of the response, the presence or absence of knowledge about the behavior, and the way in which the strength of the behavior is measured.
