chapter 5- models to explain learning Flashcards
conditioning
the process of learning associations between a stimulus (or event) in the environment and a behavioural response.
two types of conditioning
Classical conditioning
Operant conditioning
Classical conditioning
a type of learning that occurs through repeated association of 2 (or more) different stimuli (things).
stimulus
any event that elicits (produces) a response from an organism.
response
a reaction by an organism to a stimulus
the key elements of classical conditioning
- Neutral stimulus (NS)
- Unconditioned stimulus (UCS)
- Unconditioned response (UCR)
- Conditioned stimulus (CS)
- Conditioned response (CR)
Neutral stimulus (NS)
a item/object/action that fails to produce a response prior to being conditioned
- bell
Unconditioned stimulus (UCS)
any stimulus that consistently produces a particular naturally occurring automatic response.
- food
Unconditioned response (UCR)
is the response that occurs automatically when the unconditioned stimulus (UCS) is presented.
-salivation
Conditioned Stimulus (CS)
the stimulus that is neutral at the start of the conditioning process and does not normally produce the unconditioned response on its own.
UCS(food)+CS(bell)
Conditioned Response (CR)
the learned response that has been learned and produced by the condition stimulus (CS)
CS(bell)=CR(salivating)
Stimulus generalisation
the tendency for another stimulus, that is similar to produce a response that is similar to the CR.
Stimulus discrimination
The organism only responds to the CS and no other similar stimuli
Extinction
the gradual decrease in the strength or rate of a CR that occurs when the UCS is no longer present.
Spontaneous recovery
the CR reappearing when the CS is presented, after a rest period or ‘break’ has occurred, and the CR would have been seen to be extinct.
ethical considerations of little Albert experiment.
-withdrawal rights: not clear in Watson’s report whether this was exercised
Informed consent: it is believed the mother did not know
Debriefing: Albert’s fear was never extinguished prior to the experiment ending
operant conditioning
IS a learning process where the likelihood of a particular behaviour occurring again is determined by its consequences
voluntary process
operant
a response that occurs on the environment to produce some kind of effect
ABC THREE PHASE MODEL
antecedent , behaviour , consequences
antecedent
A STIMULUS THAT OCCURS BEFORE THE BEHAVIOUR - before
behaviour
THAT OCCURS DUE TO THE ANTECEDENT - during
consequences
to the behaviour - after
reinforcement
is said to occur when a stimulus (event or object) strengthens or increases the frequency or likelihood of the response (behaviour) occurring again.
reinforcer
any stimulus (object or event) that strengthens or increases the frequency or likelihood of the response (behavior) occurring again. - an reward
types of reinforcers
positive reinforcement
negative reinforcement
punishment
response cost
positive reinforcement
any stimulus that STRENGHENS a response by providing a pleasant or satisfying consequence.
increase the frequency or likelihood of that behaviour occurring again.
money/ good grades
negative reinforcement
the removal or avoidance of an unpleasant stimulus.
increase the frequency or likelihood of that behaviour occurring again
headache/panadol
punishment
(sometimes called positive punishment): occurs when a behaviour is followed by a negative experience. likely to decrease the frequency or likelihood of that behaviour occurring again
eg. chores for not doing homework
negative punishment
involves the removal or loss of a stimulus and thereby decreasing (or weakening) the likelihood of a response occurring again.
eg. taking away your internet access for a week for doing something wrong
Response cost
is a form of punishment that occurs when something desirable is removed, &/OR ‘costs’ you (is of value to you).
eg. Being fined for speeding on the roads, costing you ether a fine (loss of cash) or driving suspension (loss of freedom to drive).
key processes in operant conditioning
extinction
stimulus generalisation
stimulus discrimination
spontaneous recovery
extinction
Gradual decrease in frequency of a conditioned behaviour following a period without reinforcement
spontaneous recovery
Reoccurrence of conditioned behaviour after extinction has occurred and without any reinforcement
stimulus generalisation
When the desired behaviour occurs in response to a stimulus that is similar to the original environmental stimulus
stimulus discrimination
When the conditioned behaviour ONLY occurs in response to the particular stimulus, and not to any other similar stimuli
observational learning
occurs when someone uses observation of another model’s (person’s) actions and their consequences to guide their future actions.
vicarious conditioning
an individual watches a model’s displaying behaviour that is either reinforced or punished AND then behaves in exactly the same way or in a modified way OR refrains from the behaviour as a result of what they have observed.
Vicarious reinforcement
increases the likelihood of the observer behaving in a similar way to a model whose behaviour is reinforced.
Vicarious punishment
occurs when the likelihood of an observer preforming a particular behaviour decreases after having seen the model’s behaviour being punished.
results of the bobo doll experiments
-Children who saw the model being rewarded, or having no consequences, were more likely to be aggressive
than children who observed the model being punished.
-Boys tended to be more aggressive than girls
-However, when rewarded, girls were almost as aggressive
-Both genders in all conditions were more aggressive when they were rewarded for their own aggression
conclusions of the bobo doll experiments
- Most children had acquired the learned response (aggression), but did not perform it until rewarded themselves
- Observational learning can occur even if the model’s behaviour receives no consequences
- Observed behaviours are more likely to be performed if the learner is expecting reinforcement (vicariously or actually)
processes of observational learning
- attention
- retention
- reproduction
- motivation
- reinforcement
attention
Pay attention in order to observe the modeled behaviour
retention
Mentally retain what has been observed
reproduction
Be capable of Reproducing the behaviour
- can’t be physically limited
motivation
The learner has to be motivated
- Motivation is influenced by the prospect of reinforcement
reinforcement
The learner may have some reinforcement.
- External
-Vicarious
-Self
