Topic 4: Learning Flashcards
What is learning?
- enduring change due to response of an experience
- change/adaptation to behaviour
- can change the way we perceive, think, feel, act
- cannot be observed directly = inferred from behaviour observed
What are the 3 main types of learning?
- classical conditioning
- operant conditioning
- modelling/observational learning (cognitive-social)
What is classical conditioning (CC)?
learning of a new association/relationship between two previously unrelated stimuli
What is only applied to CC?
reflexes and autonomic responses
What is the process of CC?
stimulus elicit sensory/behavioural response + automatic reflexive response = behavioural response outside out conscious awareness
Who is associated with CC?
Ivan Pavlov - salivating dogs - Pavlovian Conditioning John Watson (behaviourism) - little Albert - reflexive emotional response
Model of CC
Prior:
UCS (meat) - UCR (salivation)
NS (bell) - No UCR (no salivation)
During:
NS (bell) - UCS (meat) - UCR (saltivation)
After:
CS (bell) - CR (salivation)
What is operant conditioning (OC)?
learning of a new association between behaviour and its consequences = voluntary response
reinforcement + punishment
OC and reinforcement
INCREASES likelihood of future behaviour
+ reinforcement = pleasant stimulus
- reinforcement = removal of aversive stimulus
OC and punishment
DECREASES likelihood of future behaviour
+ punishment = aversive stimulus
- punishment = removal of pleasant stimulus
Who is associated with OC?
B.F Skinner - skinner box; rats and reward system
Problems of punishment
learner may not understand which behaviour is being punished, fear the ‘punisher’, may not undo existing rewards for a behaviour, punitive aggression = future aggression
Schedules of reinforcement
how often and when we receive reinforcement
Continuous reinforcement
behaviour reinforced every time it occurs, best used during initial learning
Intermittent/partial reinforcement
behaviour reinforced part of the time, more difficult to extinguish
