This introductory textbook is written specifically for qualified nurses who are working in intensive care units and also for those undertaking post-registration courses in the speciality. This accessible text is: ■ Comprehensive: it covers all the key aspects of intensive care nursing. Jane Roe is a Lecturer-Practitioner at St George’s Hospital Medical School and Kingston University, St George’s Hospital Intensive Therapy Unit. What the reviewers said: ‘An informed, well written and clinically focused text that has ably drawn together the central themes of intensive care course curricula and will therefore be around for many years…. Revision activities and clinical scenarios should encourage students to learn as they engage in analysing and reflecting on their everyday practice experiences. More experienced nurses will also find it a valuable reference source as a means of refreshing their ideas or in developing practice.
Operant conditioning cheap grifulvin v 250 mg with mastercard fungus in blood, on the other hand, is learning that occurs based on the consequences of behavior and can involve the learning of new 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. In operant conditioning the organism learns from the consequences of its own actions. How Reinforcement and Punishment Influence Behavior: The Research of Thorndike and Skinner Psychologist Edward L. Thorndike (1874–1949) was the first scientist to systematically study [1] operant conditioning. In his research Thorndike (1898) observed cats who had been placed in a “puzzle box‖ from which they tried to escape (Note 7. But eventually, and accidentally, they pressed the lever that opened the door and exited to their prize, a scrap of fish. 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. Observing these changes in the cats‘ behavior led Thorndike to develop hislaw 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 [2] unpleasant outcome are less likely to occur again in the situation (Thorndike, 1911). 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. Unsuccessful responses, which produce unpleasant experiences, are “stamped out‖ and subsequently occur less frequently. Video Clip: Thorndike’s Puzzle Box 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. Thorndike described the learning that follows reinforcement in terms of the law of effect. Skinner (1904–1990) expanded on Thorndike‘s ideas to develop a more complete set of principles to explain operant conditioning. Skinner created specially designed environments known as operant chambers (usually called Skinner boxes) to systemically study learning. A Skinner box (operant chamber) 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. The most basic of Skinner‘s experiments was quite similar to Thorndike‘s research with cats. A rat placed in the chamber reacted as one might expect, scurrying about the box and sniffing and clawing at the floor and walls. Eventually the rat chanced upon a lever, which it pressed to Attributed to Charles Stangor Saylor. The next time around, the rat took a little less time to press the lever, and on successive trials, the time it took to press the lever became shorter and shorter. Soon the rat was pressing the lever as fast as it could eat the food that appeared. As predicted by the law of effect, the rat had learned to repeat the action that brought about the food and cease the actions that did not. Skinner studied, in detail, how animals changed their behavior through reinforcement and punishment, and he developed terms that explained the processes of operant learning (Table 7. Skinner used the termreinforcer to refer to any event that strengthens or increases the likelihood of a behavior and the term punisher to refer to any event that weakens or decreases the likelihood of a behavior. And he used the terms positive and negative to refer to whether a reinforcement was presented or removed, respectively. Thus positive reinforcement strengthens a response by presenting something pleasant after the response and negative reinforcement strengthens a response by reducing or removing something unpleasant. For example, giving a child praise for completing his homework represents positive reinforcement, whereas taking aspirin to reduced the pain of a headache represents negative reinforcement. In both cases, the reinforcement makes it more likely that behavior will occur again in the future. Punishment, on the other hand, refers to any event that weakens or reduces the likelihood of a behavior. Positive punishment weakens a response by presenting something unpleasant after the response, whereasnegative punishment weakens a response by reducing or removing something pleasant. A child who is grounded after fighting with a sibling (positive punishment) or who loses out on the opportunity to go to recess after getting a poor grade (negative punishment) is less likely to repeat these behaviors.
