Approaches: The Behavioural Approach Flashcards
What is the behavioural approach and when was it founded?
It was founded by JB Watson in 1915, emerging at the beginning of the 20th century. It rejected the vagueness of introspection and instead focuses on how we are a product of our learning, experience and environment
What are some assumptions of the approach?
Behaviourism is primarily concerned with observable behaviour, opposed to internal events such as emotion
Psychology is a science so behaviour must be measured in highly controlled environments to establish cause and effect
When born, the mind is a blank slate
There is little difference between the learning that takes place in humans and that in other animals
All behaviour no matter how complicated is the result of stimulus - response
All behaviour is learnt from the environment, we learn new behaviour through classical or operant conditioning
What is a stimulus
Anything internal or external, that brings about a response
What is a response?
Any reaction in the presence of a stimulus
What is reinforcement?
The process by which a response is strengthened
What was the little Albert Watson and Rayner study (1920)?
11 month old, no fear of white fluffy objects such as rats or rabbits. Researchers tried to create a conditioned response to these objects. A white rat was placed in front of LA, as he reached out to it, a metal bad was struck loudly behind his head. This was repeated twice at first, then five more times a week later.
What were the findings of the little Albert Watson and Rayner study (1920)?
When he was shown a rat, he would start to cry. This also extended to other white fluffy objects such as a White Santa beard.
What can we conclude from the little Albert Watson and Rayner study (1920)?
A fear response to white fluffy objects had been conditioned to LA, showing that abnormal behaviour can be learned
What are the positive evaluations of the little Albert Watson and Rayner study (1920)?
The results supported Pavlov’s idea of classical conditioning.
It was a very significant experiment in the field of psychology because it demonstrates that associating a stimulus or behaviour with an unrelated one can be done
What are the negative evaluations of the little Albert Watson and Rayner study (1920)?
The experiment was unethical and could not be repeated today
Not everyone goes on to develop a fear or phobia following a negative situation, so learning theory cannot be the full story
It was a lab study, so it lacks ecological validity as the situation was artificial
What is classical conditioning?
Learning by association. It refers to the conditioning of reflexes and involves associating a new stimulus with an innate bodily reflex. It involves pairing a response naturally caused by one stimulus with another, previously neutral stimulus
What is an unconditioned stimulus?
The stimulus that causes the reflex response before conditioning. It naturally produces the response
What is a conditioned stimulus?
The stimulus which after repeated parings with the unconditioned stimulus, produces the response
What is an unconditioned response?
The innate reflexive response to a stimulus that has not been conditioned yet
What is a conditioned response?
The response that occurs after exposure to the conditioned stimulus
What were the stages of Pavlov’s dogs experiment?
First he established the meat caused the dog to salivate (unconditioned stimulus (food) = unconditioned response (saliva)
He found the tone did not cause salivation
He then presented the tone with the food (unconditioned stimulus (food) + neutral stimulus (bell) = unconditioned response (saliva))
After several pairings of food + tone, Pavlov found that the dog would salivate to the tone presented alone (conditioned stimulus (bell) = conditioned response (saliva))
What is Operant conditioning (BF Skinner)?
Skinner claimed that all behaviour is learnt as a result of consequences in our environment (operant conditioning). This involves learning through the consequences (positive and negative) of behavioural responses. Associations between responses and consequences have to be made close together for learning to occur
What is positive reinforcement?
Increases the likelihood of a response occurring because it involves a reward for behaviour e.g. rewards for good work
What is negative reinforcement?
Increases the likelihood of a response occurring because it involves the removal of, or escaping from, unpleasant consequences, e.g. escaping an electric shock
What is punishment?
The consequence is receiving something unpleasant which decreases the probability of the behaviour being repeated, e.g. an electric shock or smacking
What was Skinner’s (1938) rat experiment?
Created a Skinner box, in which he placed a rat at a time. Each box contained a variety of stimuli, such as a speaker, lights, a floor which gave an electric shock and a food dispenser which dispensed when a lever was pressed. A hungry rat was placed in the box, the time taken for ears to learn that the levee would release food was recorded. Initially, the rat would run about until ur accidentally pulled the lever and it was rewarded with food. The more the rat was put in the box, the Whicker they got at learning where the lever was. Skinner also tested negative reinforcement with rats pressing the lever as the light came on (which prevented an electric shock)
What can we conclude from Skinner’s (1938) rat experiment?
Rats can learn behaviour through operant conditioning. A behaviour such as pressing a lever can be reinforced by receiving food
What are the positive evaluations of Skinners (1938) rat experiment?
Skinners experiment has been highly influential in promoting the idea of behavioural psychology
What are the negative evaluations of Skinner’s (1938) rat experiment?
The experiment used animals, which means results might not be generalisable to humans
The sample size was small, which reduces reliability
