Approaches: The Behaviourist Approach Flashcards
What does the behaviourist approach suggest?
This perspective believes that we are born a blank slate, and that we learn our behaviour as a result of out experiences in our environment.
Therefore this is a untrue explanation
Why did early behaviourists like John B Watson reject introspection?
It involved too many concepts that were vague and difficult to measure.
Who researched classical conditioning in dogs?
Ivan Pavlov (1927)
What is classical conditioning?
Is when a stimulus creates a response, but this is a new response - one we never had before
What is Pavlovs process of classical conditioning?
Before conditioning:
- Bell (NS) —> no response
- Food (UCS) —> salivates (UCR)
During conditioning:
- Bell (NS) + Food (UCS) —> Salivates (UCR)
After conditioning:
- Bell (CS) —> Salivates (CR)
What’s a case study supporting classical conditioning?
Raynor and Watson carried out a famous experiment using CC to demonstrate the origins of fears and phobias.
They looked at Little Albert and found he liked this white rat (not frightened at all), yet was frightened by a loud noise that made him cry
Before the experiment:
- Rat = no fear
- noise = fear
During the experiment:
- Rat + noise = fear
After experiment:
- rat = fear
What’s some strengths of classical conditioning?
+ successfully used to explain phobias
+ shows the importance of nuture and the environment influence on behaviour
+ high controls and can establish cause and effect as studied in a lab. Replicable and objective (nomothetic)
What are some weaknesses to classical conditioning?
- ignore what happens between the stimulus and response (e.g. thinking)
- oversimplifies human behaviour to ‘object = response’ and ignores other possibilities (reductionist)
- no completely generalisable as the behaviour of animals and humans is very different
Who proposed operant conditioning?
BF Skinner (1953) suggested that learning theory is an active process whereby humans and animals operate in their environments. There are 3 types of consequences of behaviour:
1. Positive reinforcement
2. Negative reinforcement
3. Punishment
What is positive reinforcement?
This is receiving a reward when a certain behaviour is performed - e.g. a prise or praise from your teacher for answering a question correctly in class
What is negative reinforcement?
Occurs when animal or humans avoid something unpleasant. When a students hands in an essay, so not be told off, the avoidance of something unpleasant is the negative reinforcement.
- e.g. a rat pressing a lever to stop being electrocuted
What is punishment?
An unpleasant consequence of behaviour, e.g. being shouted at by the teacher during the lesson (finding a way to avoid that would be negative reinforcement)
What’s the difference between reinforcement and punishment?
Positive and negative reinforcement increase the likelihood that behaviour will be repeated.
Punishment decreases the likelihood that that behaviour will be repeated.
What is Skinners box experiment?
Skinner conducted an experiment with rats and sometimes pigeons in a box. Everytime the rat activated a lever, it was rewarded with a food pellet. From then on the rat would continue to perform the behaviour.
- also showed how rats can be conditioned to perform the same behaviour to avoid an unpleasant stimulus (e.g. an electric shock)
What is continuous reinforcement?
The desired behaviour is reinforced every single time it occurs, may result in a stronger response
