Theoretical approahe's to psychology
Psychology, the study and exploration of the limitless psyche. For many years people have dedicated their entire life's work to uncover the causes and motives behind the behaviour of both humans and animals

Various theories have been constructed based on incalculable research. The most contemporary of perspectives include Behaviourism, the assumption that all behaviour is learned. Influenced by the environment, behaviourists believe that we are born a blank canvas and that we are susceptible to manipulation by any chosen stimulus.

In 1902 while experimenting on dogs, a Russian physiologist named Ivan Pavlov discovered that the dogs began to salivate whenever the lab assistant appeared. Coincidence or not the lab assistant was usually the one who fed the dogs. Pavlov concluded that this association was as a result of learning and so proceeded to investigate further.

He sought to find out if ringing a bell (NS) immediately before serving the dogs food (US) prompted the dogs to salivate (UR). After several trials, the bell ringing (NS) caused the dogs to salivate thus becoming a learned response (CS) because the dogs now associated the bell ringing with the arrival food (US). This started the (CR) salivation even before the dogs could see or smell the food.(K,Cherry)

Operant conditioning discovered by B F Skinner (1940) brought forth suggestions on behaviour modification. Having invented the 'Skinner box' in which a hungry rat was placed, Skinner introduced the the term positive reinforcement. Inside the box was a lever which ultimately when pressed accidentally by the rat would release food pellets. Eventually the rat realised that by pressing the lever it would reap rewards in the form of food. The reinforcement was positive as it increased a desired behaviour with the notion of something pleasant. Skinner concluded that reinforcement including negative reinforcement ( an increase in behaviour to avoid anything unpleasant ) was the primary

    In 1948, Skinner conducted experiments on rats and pigeons by putting them in a ‘Skinner box’. B.F. Skinner (1938) came up with a term operant conditioning. It means that particular behaviour is changed by the use of reinforcement which is given after the desired response. In this case, it was a small pellet of food which dropped into a food tray and could be eaten.…

    Skinner also investigated negative reinforcement by running a very small electric current on the floor of the box containing the rat and if the rat pushed the lever then the current would be turned off. This action was negative reinforcement. An example of this is taking a painkiller to relieve the symptoms of a headache which results in…

    According to Crittenden, behavior 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.…

    Ivan Pavlov was a Russian Physiologist. At the end of the 19th century Pavlov was conducting research into the physiology of digestion in dogs. During an experiment he discovered something very interesting about the dogs’ behaviour and started studying it. He came up with the theory of classical conditioning, which lead on to more research into behaviour.…

    Skinner thought classical conditioning was too simple to explain something like the human mind. Skinner went to work to expand on the finding of Thorndike and Watson. Skinner worked to expand Thorndike’s Law of Effect. Skinner eventually coined the word “operant conditioning”. Skinner built a device called “Skinner’s box”. The device consists of a lever connected to a food dispenser, only dispensing when the lever is pressed. He found that the rat will reduce “error” between attempts and goes directly to the lever. The device has reinforced the rat’s behavior. From this experiment, Skinner discovered positive and negative reinforcement. A positive reinforcement means giving a stimuli and a negative reinforcement is taking away a stimuli, along with punishment. Punishment weakens the behavior rather than reinforcement which strengthen the behavior. Positive and negative reinforcement works on punishment too. The Skinner Box also showed that the reinforcement had to be scheduled or else the rats will start giving…

    A neutral stimulus (such as a bell) which normally wouldn’t produce a response (such a salivating) eventually becomes paired with another stimulus (such as the food) this is referred to an unconditional response. When the bell and food (unconditional stimulus) are paired often enough the dogs start to salivate as soon as they hear the bell and before the food is served. When this occurs conditioning has taken place. (Cited in Burns 1995) Pavlov argued that if dogs could be conditioned to salivate then it is possible to apply the process to bodily process that effect illness and mental health disorders. Nowadays classical conditioning is applied in the treatment of phobias and in aversion therapies.(Cited in Burns 1995).…

    B.F Skinner was an American Psychologist who invented the operant conditioning chamber. The chamber he set up had rats in it and a lever, once the rats pulled the lever they were given a piece of food. After this happened the rate of bar pressing would increase dramatically and remain high until the rat was no longer hungry. He was a firm believer of the idea that human free will was actually an illusion and any human action was the result of the consequences of that same action. If the consequences were bad, there was a high chance that the action would not be repeated; however if the consequences were good, the actions that lead to it would be reinforced. He called this the principle of reinforcement.…

    Skinner believed that behaviours that created a positive response are therefore reinforced and continued, whilst behaviour that creates a negative response would be more likely to be eliminated. His investigation of Operant Conditioning on pigeons and rats uncovered, he believed, that many of the principles of Operant Conditioning could be applied to humans.…

    During the 1890s Ivan Pavlov ran an experiment based on innate response. His experiment was based of dogs and their behavior with potential stimuli. In this situation the stimuli was food, and their salivary response to food. The study was conducted when Pavlov would ring a bell before every meal; therefore, the dogs would know it would be dinnertime. After duration of ringing the bell before meals the dogs would expect to receive food every time and the bell would ring. In response to bell and the expectancy of food the dogs would…
