Behaviourist approach Flashcards
What is the behaviourist approach?
A way of explaining behaviour in terms of what is observerable and learning
Classical conditioning
Learning by association. Occurs when two stimuli are repeatedly put together
Operant conditioning
A form of learning in which behaviour is shaped and maintained by its consequences. These include reinforcement and punishment
Reinforcement
A consequence of behaviour that increases the likelihood of that behaviour being repeated. Can be positive or negative
What are the core assumptions?
- Behaviour is learned from experience 2. Humans are all born as a blank slate, there is no genetic influence on behaviour 3. only observable behaviour is scientific and measurable, this is what should be studied 4. It is valid to study animals as they share the same principles of living as humans
What is positive reinforcement?
Receiving reward when a certain behaviour is shown
What is negative reinforcement?
When we avoid something unpleasant and the outcome is positive experience e.g. putting a hand up to avoid being told off
What is punishment?
Negative consequence of behaviour
What do the different reinforcements and punishment achieve?
Positive and negative reinforcement increase the likelihood of behaviour recurring but punishment decreases the likelihood
What is the skinner box? (operant conditioning chamber)
- Rats were put in specially designed boxes, every time a rat activated a lever, it was given food pellets. Therefore the rat continued the behaviour. (POSITIVE REINFORCEMENT)
- Rats were put into the box and there would be an electric current which caused them discomfort. When they activated the lever it would stop. So therefore everytime they were put in the box they would activate the lever. (NEGATIVE REINFORCEMENT)
What core assumption does the skinner box link to?
- ‘It is valid to study animals as they share the same principles of learning as with humans’
Strengths of the approach?
- Based on well-controlled research in a highly controlled lab setting (extraneous variables removed)
- Skinner showed reinforcement influenced animals behaviour
- Behaviourist experiments have scientific credibility
- Principles of conditioning have been applied to real life behaviours
- Operant conditioning basis of token economy systems in institutions like prisons and psychiatric wards
- Classical conditioning has been applied to treatment of phobias
Weaknesses of approach
- Oversimplified learning process - behaviourists ignored important influence on human behaviour, human thought
- Behaviour is conditioned from past experience so it determines the outcome
- Ignores influence of free will on behaviour
- Ignores influence on conscious decision
- Ethical issues as animals were kept in harsh conditions and always hungry
