Q

When is learning said to ‘only’ have occurred?
Hint: within Classical Conditioning

A

Q

Discuss John B. Watson

A

1878, taught at John Hopkins University
Argued that fear, rage and love are basic emotions from which all other emotions arise by conditioning.
Conducted the Little Albert Experiment.
Fired from university for having affair with student

Q

Discuss the Little Albert Experiment

A

Initially, Little Albert was not scared of animals
He met a white rat, which he liked
Then, every time he reached for the rat, a pipe was hit loudly
Then, when only the rat was shown, Albert showed fear (Conditioned Emotional Response)
Then Albert was shown other white fluffy objects, and was scared (stimulus generalisation)

18
Q

What therapeutic benefits can arise from classical conditioning

A

Extinguishing phobias.
Typically, a conditional response eventually weakens and dies once the conditioned and unconditional stimuli are unpaired. In some cases though, the conditioned response persists in the absence of the unconditioned stimulus.

19
Q

Discuss Graduated Exposure

A

Gently exposing a subject to a conditioned stimulus until it no longer elicits the conditioned response

20
Q

Discuss Flooding

A

Rather than gradually exposing a subject to a conditioned stimulus, this method exposes the subject suddenly to the stimulus, and continues to consistently expose them until the response is extinguished. This method is quite traumatic and can result in adverse effects

21
Q

Discuss Aversion therapy

A

Seeks to block or discourage behaviours by associating (pairing) them with aversive stimuli (e.g. an electric shock every time you reach for a piece of cake)

22
Q

Discuss Thorndike and his cats’ experiment

A

In the 1900s, Edward Thorndike identified instrumental learning (an early version of operant conditioning) is learning by trying different behaviours, repeating or tweaking successes and not repeating failures until the desired outcome is achieved

23
Q

Discuss B.F. Skinner

A

Considered the father of Operant Conditioning, Skinner proposed the three-phase model of operant conditioning: antecedent (preceding events), response (the event) and consequence (events that follow the response)

24
Q

Define Operant Conditioning

A

A process in which behaviour is sensitive to, or is controlled by its real or perceived consequences. This type of behaviour is increased if followed by a reward, and weakened if followed by a punishment

25
Q

Define positive and negative reinforcement

A

Positive reinforcement: introducing something (could be something bad)
Negative reinforcement: Taking something away

26
Q

Define positive and negative punishment

A

Positive (adding something undesirable)
Negative (removing something good)

27
Q

Types of Reinforcement schedules

A

Continuous (target behaviour every time it is performed)
Partial: sometimes reinforce behaviour, sometimes not.

28
Q

Types of partial reinforcement schedules

A

Fixed ratio (fixed number of times behaviour is reinforced)
Fixed interval (fixed time behaviour is reinforced)
Variable ratio (reinforcement varies, like a slot machine)
Variable interval (random)

29
Q

What are primary and secondary reinforcers?

A

Primary: basic needs: food, water, shelter, sex
Secondary: seen as ways to get us to primary needs - money, status, a good job, etc

30
Q

Define shaping

A

Incrementally rewarding partial behaviour until the full behaviour is displayed

31
Q

Token economics

A

Items that have no intrinsic value, but we are conditioned to think that they do: money being a key example

32
Q

Define learned helplessness

A

An organism being exposed to adverse stimuli so often, that they ‘give up’ and stop trying to escape, even when they can leave

33
Q

Define two factor learning

A

Mowrer’s 1960 theory:
1. An organism associates stimuli in the environment with aversive stimuli, and this allows these stimuli to evoke fear (classical)
2. The avoidance response is reinforced with relief that comes from avoiding or escaping these fear/anxiety inducing stimuli (operant)

34
Q

What are the five phenomena found in both classical and operant conditioning?

A

Acquisition, Extinction, Spontaneous Recovery, Stimulus Generalisation and Stimulus Discrimination

35
Q

What is Acquisition in classical and operant conditioning?

A

Classical: a process by which an organism learns to associate a neutral stimuli with an unconditioned stimulus (Pavlov)
Operant: establishment of a response through reinforcement

36
Q

What is Extinction in classical and operant conditioning?

A

Classical: The gradual weakening of a conditioned response that occurs when the unconditioned stimulus is no longer presented
Operant: When a conditioned response is followed by consistent non-reinforcement

37
Q

What is spontaneous recovery in classical and operant conditioning?

A

Classical: the reappearance of a conditioned response to a conditioned stimulus following a rest period after the conditioned response appeared extinguished
Operant: when, following a period of rest and the apparent loss of the conditioned response, the organism shows the response again in the absence of any reinforcement

38
Q

What is stimulus generalisation in classical and operant conditioning?

A

Classical: when a stimulus that is similar but not identical to the conditioned stimulus elicits a similar (though not exactly the same) response to the conditioned response
Operant: when the correct response is made to a similar but not identical stimulus to the conditioned stimulus

39
Q

What is stimulus generalisation in relation to classical and operant conditioning?

A

Classical: when an organism responds to the conditioned stimulus only, not any other similar stimulus
Operant: when an organism makes the correct response to a stimulus and is reinforced but does not respond to any other stimuli, even if they are similar

40
Q

What is behaviourism?

A

A school of though that Pavlov, Watson, Raynor and Skinner created that insisted that learning could only occur as a result of external environmental stimuli and not because of internal thoughts and processes. Also the notion that humans are born as ‘blank slates’ and are 100% shaped by their experiences. This school of thought is widely out of fashion and relevance today.
