The assignment content discusses Operant Conditioning (OC) and Classical Conditioning (CC) theories in psychology. OC was discovered by B.F. Skinner, who introduced the concept of reinforcement as a means to change behavior. There are three types of responses: reinforcers, neutral operants, and punishers. The theory is different from classical learning in that it involves voluntary behavior and independence. Classical conditioning, on the other hand, refers to involuntary behavior dependent on external stimuli. The main components of OC are reward and punishment, while those of CC are stimuli and response. The two theories differ in their approaches, with OC involving voluntary behavior and CC involving reflexive and involuntary responses.
