define the behaviourist approach
assumptions:
classical conditioning
= This is learning through association
- We learn to associate a previously neutral stimulus with a stimulus that already produces a response
- Through regular pairing, the neutral stimulus becomes a conditioned stimulus producing a new learned response (conditioned response)
classical conditioning = pavlovs dog
Pavlov conditioned dogs to salivate when a bell rings
Before conditioning: UCS = food, UCR = salivation, NS = bell
UCS → UCR
NS → No response
During conditioning: bell and food occur at the same time
NS + UCS
After conditioning: CS = bell, CR = salivation
CS → CR
- When the bell rang the dog started to salivate even when there was no food present
- Pavlov showed how a neutral stimulus (bell) can come to elicit a new learned response (conditioned stimulus) through association

what is operant conditioning?
This is learning through the consequence
operant conditioning: 3 types of consequences
Positive reinforcement and negative reinforcement increase the likelihood that behaviour will be repeated. Punishment decreases it.
operant conditioning : skinners box
● Rats and pigeons in specially designed cages
● Positive reinforcement: when a rat activated a lever (or a pigeon pecked a disc) it was rewarded with a food pellet
- a desirable consequence led to behaviour being repeated
● Negative reinforcement: the rat would also press a lever to avoid an electric shock, and this behaviour would also be repeated
