4.2.1 - Behavourist Approach Flashcards
What is the key approach
Nothing is innate, all behaviour is learnt from the environment
Features of behaviourist approach
• Uses classical conditioning: learning through association by pairing two stimuli together.
↳ UCS → UCR
UCS + NS → UCR
CS→ CR
• Uses operant conditioning: learning through rewards and consequences (positive/negative reinforcement & punishments)
↳ token economy
Research methods used in behaviourist approach
lab environments are used to
carry out Investigations:
- little Albert and pavlovs dogs (classical conditioning)
- Skinners box (operant conditioning)
Negatives of the behaviourist approach
- little Albert investigation was unethical, he experienced
stimulus generalisation and trauma - Skinners box cannot be directly compared to humans as we have a higher level of consciousness. Animals will also not respond to demand characteristics
- Ignores cognition and emotion.
- token economy is unethical as it shapes behaviour and the effects are only short term
Describe little Albert investigation
Before conditioning:
rat(NS) > no fear
Hammer(UCS) > fear(UCR)
During conditioning:
Rat(NS) + Hammer(UCS) > fear(UCR)
After conditioning:
Rat(CS) > fear(CR)
Describe Pavlovs dogs
Before conditioning:
Food(UCS) > dog salivates(UCR)
During conditioning
Food(UCS) + bell(NS) > dog salivates(UCR)
After conditioning:
Bell(CS) > dog salivates(CR)
Explain positive reinforcement
Receiving a reward when certain behaviour is carried out, strengthening behaviour.
Explain negative reinforcement
The want to avoid something unpleasant
Explain punishment
An unpleasant consequence of behaviour
Describe skinners box investigation
Conducted experiments on rats and sometimes pigeons
- demonstrated positive reinforcement:
Every time the rat activated the lever, they were rewarded with a food pellet. The rat would then continue to activate the lever.
- demonstrated negative reinforcement:
The box would have an electric floor that shocker the rats. The lever in the box turned off the electric floor when activated by the rats, so they would continue to activate the lever.
