  1. Behaviourist Theory

According to Crittenden,  et al. (2005) behaviour is learnt through seeing what someone else does. This can be explained further through the experiment of classical conditioning. Classical Conditioning was developed by Ivan Pavlov.  Pavlov used the experiment of dogs and food so as to measure the levels of salivation that a dog produced when food had been associated with the assistant. He developed this experiment when he noticed that the dog was starting to salivate at the sight of the bowl of the food and not the taste. He decided to experiment further and he introduced a bell which was the neutral stimulus, it had no effect at the start but when he rang the bell when he brought the food to the dogs they started to associate the food (which made them salivate) with the bell. Now that classical conditioning had taken place the dogs would salivate at the sound of the bell which was now the conditioned stimulus.

Another form of learning was shown in operant conditioning or reinforcement. This type of leaning was introduced by B.F. Skinner. He was famous for inventing the Skinner box, in which he used rats to show reinforcement, both positive and negative. The Skinner box consisted of a lever and a food dispenser in which if the rat pressed the leaver it received a pellet of food (positive reinforcement), from this behaviour the rat would start to repeatedly press the leaver as it was receiving a reward. Skinner believed this proved that a reward can repeat a behaviour. On the other hand Skinner showed that negative reinforcement can occur by taking away the reward and replacing it with a small electric shock, so when the rat pressed the lever they would receive a small shock, from this form of punishment the rat quickly stopped pressing the lever.This showed that an unpleasant reward can stop a behaviour from re-occurring. According to psychology.about ‘Skinner used the term operant to refer to any "active behavior that operates upon the environment to generate consequences" (1953).’(Stretch and Whitehouse 2007)

  1. Describe the application of behaviourist perspectives in health and social care.

According to Stretch and Whitehouse (2007) we can apply classical conditioning to everyday life. This is very good for explaining fears of phobias. The term neutral stimulus can be paired to any type of un-conditioned stimulus which then becomes a conditioned stimulus. For example a child being bitten by a rat whilst chewing gum, being bitten by the rat can release fear and that child having a phobia of rats but can also be reminded of the traumatic experience by just smelling or chewing gum. To overcome these fears psychologists use a treatment called systematic desensitisation. This treatment uses a hierarchy of fear from the least frightening to the most. From the example seeing a photo of a rat may be the least to touching the rat the most frightening. This procedure uses deep relaxation to keep the patient calm and relaxed as the psychologist helps them to deal with their phobia. The psychologist will start with the least frightening and help them to deal with it in a calm manner; they will then repeat this step covering more and more frightening levels of the hierarchy until they reach the most frightening whilst keeping the patient calm and relaxed. From this therapy the client will feel relaxed when they come in contact with their phobia and will be able to cope with the situation. This could be used in a health and social care setting according to suite101 Systematic desensitization is used to treat specific phobias, such as fear of heights or spiders.’

  1. Using case study 1 describe how behaviourist theory and social learning theory can be applied to challenging behaviour

The behaviourist theory suggests using; operant conditioning may help Tom to overcome this agitated behaviour that he was feeling at toy time ending. Care workers should use positive reinforcement to encourage him to tidy up the toys. They could introduce a reward chart that when he tidied his toys away when asked he would receive a star which would be positive reinforcement and if he didn’t then he would lose a star negative reinforcement. From this Tom may feel that if ...
