Chapter 4 Approaches to Learning Flashcards
Classical Conditioning (Pavlov)
Classical Conditioning is a process of learning through the involuntary association between a neutral stimulus and an unconditioned stimulus that results in a conditioned response.
(Behaviourist approach to learning)
What happens in phase 1 before conditioning phase?
The neutral stimulus has no associations and therefore does not produce any relevant response. The UCS produces the UCR.
Phase 1: Before conditioning, the neutral stimulus (NS), (e.g bell), elicits no relevant response. The unconditioned stimulus (UCS) of (e.g food) elicited the unconditioned response (UCR) of (e.g salitvation) in the (e.g dog ).
Second phase: during conditioning?
Second stage of classical conditioning.
* The NS is repeatedly paired with the UCS, which in turn produces the UCR.
* the NS is to be presented half of a second before the UCS.
–
Phase 2: During conditioning, the NS (e.g bell) is presented first with the UCS (e.g food) presented immediately after (within 0.5 secs) and they are repeatedly paired together. This produces the UCR (e.g salivation) in the (e.g dog).
When should the neutral stimulus be presented during classical conditioning?
The neutral stimulus must be presented 0.5 seconds before the unconditioned stimulus. The UCS should not be presented later than this.
After conditioning phase?
The neutral stimulus becomes the conditioned stimulus, producing a conditioned response without the prescence unconditioned stimulus.
Third Phase: After conditioning, the NS, (e.g bell) becomes a conditioned stimulus (CS), producing a conditioned response (CR) of (e.g salivation) in the (e.g dog) without the prescence of the UCS, which is usually similar to the previously unconditioned response.
What is operant conditioning? (Skinner)
Operant conditioning is a three-phase learning process that involves an antecedent, behaviour, and consequence, whereby the consequence of a behaviour determines the likelihood that it will reoccur.
(behaviourist approach to learning)
What is the antecedent? Give example.
Stimulus or event that precedes or elicits a particular behaviour.
What is the behaviour? Give example.
The voluntary actions that occur in the presence of the antecedent.
What is the consequence?
The outcome of the behaviour, which determines the likelihood that it will occur again.
Factors that influence effectiveness of Operant Conditioning
Order of Presentation: reinforcement/punishment must be presented after behaviour so that it is learned as a consequence of that behaviour.
Timing: reinforcement/punishment are most effective when presented immediately after behaviour (also increases strength of response).
(promise of a reward in the future can also be a powerful influence on behaviour)
Appropriateness: reinforcement/punishment must be specific to the likes/dislikes of the individual (reward could actually be punishment)
Positive Reinforcement
The addition of a desirable stimulus, which in turn increases the likelihood of the behaviour reoccurring again in the future.
+++
Negative Reinforcement
The removal of an undesirable stimulus, which in turn increases the likelihood of the behaviour reoccurring again in the future.
- -+
Positive Punishment
The addition of an undesirable stimulus, which in turn decreases the likelihood of the behaviour reoccurring again in the future.
+- -
Negative Punishment
The removal of a desirable stimulus, , which in turn decreases the likelihood of the behaviour reoccurring again in the future.

Similarities between Operant and Classical Conditioning?
- Both behaviourist approaches to learning
- 3-phase process of learning
- Require several trials for learning to occur.
Eg. classical conditioning requires NS and UCS to be repeatedly paired whereas in operant learning it is more likely to occur if the consequence occurs several times in response to a behaviour.
Differences between Operant and Classical Conditioning?
- Operant conditioning involves learning voluntary behaviours whereas Classical involves learning involuntary behaviours.
- Learners are active during operant, whereas learners are passive during classical.
- Operant requires a consequence, whereas there is no kind of consequence during classical.
- ## immediate (classical) vs. delayed (operant)
What is observational learning? (Bandura)
Process of learning that involves watching the behaviour of a model and the associated consequence of that behaviour, either directly or indirectly
(social-cognitive approach to learning)
What factors influence whether learners pay attention?
If the model is:
* perceived positively
* liked
* of high status (such as a celebrity)
* similar to the learner
* familiar to the learner
* visible and stands out from others
* behaving in a way that the learner believes can be imitated.
What are the 5 stages of observational learning?
Attention, Retention, Reproduction, Motivation, Reinforcement.
Attention Phase?
When the learner actively watches the model’s behaviour and its consequences of that behaviour.
to learn through observation we must closely/actively watch the model’s behaviour
Retention Phase?
The learner has the mental capacity to create a mental representation of the model’s demonstrated behaviour ans stores it in their memory.
This stage allows the info they paid attention to, to be stored in their memory and accessed later.
Reproduction phase?
The learner must have the physical and mental capabilities to replicate the behaviour. If they don’t they will be unable to reproduce the behaviour.
Motivation phase?
Individuals has a desire to perform the behaviour because…
Motivation is a cognitive process in which individuals must desire to perform that behaviour.
Intrinsic Motivation - Occur from within (Eg desire to do well on exams)
Extrinsic Motivation - occur from external factors to the individual (Eg receiving praise)
Reinforcement phase?
influences the motivation to reproduce the behaviour and increases the likelihood of reproduction
(can be negative or positive )
Self-reinforcement, External reinforcement, Vicarious reinforcement.
