![]() Eventually the rat chanced upon a lever, which it pressed to release pellets of food. A rat placed in the chamber reacted as one might expect, scurrying about the box and sniffing and clawing at the floor and walls. The most basic of Skinner’s experiments was quite similar to Thorndike’s research with cats. It also contains a device to record the animal’s responses. is a structure that is big enough to fit a rodent or bird and that contains a bar or key that the organism can press or peck to release food or water. ![]() A Skinner box (operant chamber) A structure used to study operant learning in small animals. Skinner created specially designed environments known as operant chambers (usually called Skinner boxes) to systemically study learning. Skinner (1904–1990) expanded on Thorndike’s ideas to develop a more complete set of principles to explain operant conditioning. The influential behavioral psychologist B. Thorndike described the learning that follows reinforcement in terms of the law of effect. When Thorndike placed his cats in a puzzle box, he found that they learned to engage in the important escape behavior faster after each trial. Video Clip: Thorndike’s Puzzle Box (click to see video) Unsuccessful responses, which produce unpleasant experiences, are “stamped out” and subsequently occur less frequently. Retrieved from The essence of the law of effect is that successful responses, because they are pleasurable, are “stamped in” by experience and thus occur more frequently. Animal intelligence: Experimental studies. Observing these changes in the cats’ behavior led Thorndike to develop his law of effect The principle that responses that create a typically pleasant outcome in a particular situation are more likely to occur again in a similar situation, whereas responses that produce a typically unpleasant outcome are less likely to occur again in the situation., the principle that responses that create a typically pleasant outcome in a particular situation are more likely to occur again in a similar situation, whereas responses that produce a typically unpleasant outcome are less likely to occur again in the situation (Thorndike, 1911). The next time the cat was constrained within the box it attempted fewer of the ineffective responses before carrying out the successful escape, and after several trials the cat learned to almost immediately make the correct response. But eventually, and accidentally, they pressed the lever that opened the door and exited to their prize, a scrap of fish. At first the cats scratched, bit, and swatted haphazardly, without any idea of how to get out. observed cats who had been placed in a “puzzle box” from which they tried to escape ( Note 7.21 "Video Clip: Thorndike’s Puzzle Box"). Washington, DC: American Psychological Association. Animal intelligence: An experimental study of the associative processes in animals. In his research Thorndike (1898) Thorndike, E. Thorndike (1874–1949) was the first scientist to systematically study operant conditioning. How Reinforcement and Punishment Influence Behavior: The Research of Thorndike and Skinner In operant conditioning the organism learns from the consequences of its own actions. Operant conditioning occurs when a dog rolls over on command because it has been praised for doing so in the past, when a schoolroom bully threatens his classmates because doing so allows him to get his way, and when a child gets good grades because her parents threaten to punish her if she doesn’t. ![]() ![]() Operant conditioning Learning that occurs based on the consequences of behavior., on the other hand, is learning that occurs based on the consequences of behavior and can involve the learning of new actions. The organism does not learn something new but rather begins to perform in an existing behavior in the presence of a new signal. In classical conditioning the organism learns to associate new stimuli with natural, biological responses such as salivation or fear. ![]() Explain how learning can be shaped through the use of reinforcement schedules and secondary reinforcers.Outline the principles of operant conditioning. ![]()
