Q

What is learning?

A

Relatively permanent change in behaviour, knowledge, capability, or attitude that is acquired through experience. It is a change that takes place through practice or experience. Changes that occur due to accident, growth or maturation are not learning.

A

It is defined as learning by association- a type of learning that occurs when specific situations become associated with specific outcomes.

Name the two kinds of reflexes

A

Unlearned (unconditioned)
- An inborn, automatic response
Examples? Hot weather, loud bang, onion juice, touch hot pan..
Learned (conditioned)
- Salivation reflex in Pavlov’s experiment

Q

What is Pavlov’s definition of classical conditioning?

A

When a previously neutral stimulus becomes ‘paired’ (associated) with an unconditioned stimulus, and elicits a conditioned response.

Q

How can classical conditioning be unlearned?

A

extinction - Weakening of (& eventual disappearance) learned response. CR’s that are no longer needed/useful

Q

What is spontaneous recovery

A

After extinction, the animal is given a rest and then the CS is presented again, the CR reappears! (but weaker)

Q

What is generalization in relation to conditioning?

A

after conditioning, stimuli that resemble the conditioned stimulus will elicit the conditioned response even though they themselves were never paired with the unconditioned response.

Q

What is discrimination in relation to conditioning?

A

training can abolish generalization between two stimuli.
The learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimuli but not to similar stimuli.

Q

What is higher-order conditioning?

A

Takes place when a neutral stimulus is paired with an existing conditioned stimulus, becomes associated with it, and gains power to elicit the same conditioned response.
Light + tone = salivation
Light = salivation

23
Q

What is behaviourism?

A

Everything is learned, environment more powerful than genetics, life experience is key

24
Q

Tabula Rasa

A

Blank slate

25
Q

What are the four factors influencing classical conditioning?

A

Number of pairings, intensity of the US, how reliable CS predicts US, Temporal relationship between CS and US (ideally 1/2 a second)

26
Q

What did Rescorla do?

A

Demonstrated that the critical element in classical conditioning is not the repeated pairing of the CS and the US.
Its PREDICTABILITY

27
Q

Selignman (1972)

A

most common fears are related to the survival of the human species.

28
Q

Garcia and Koelling (1966)

A

Did experiments with rats - illness was associated with flavoured water - contradicted classical conditioning

29
Q

Classical conditioned responses are…

A

Involuntary, passive
and reflexive. organisms do not learn new responses; they have an existing
response to a new stimulus

30
Q

B.F. Skinner

A

Operant Conditioning

31
Q

What is shaping?

A

rather than waiting for the desired response to occur and then reinforcing it, we reinforce any movement in the direction of the desired response

32
Q

What is operant conditioning?

A

Manipulated in order to increase or decrease the frequency of a B - Influences whether B will happen again.

33
Q

What are the types of reinforcers?

A

Primary Reinforcers
To fulfill a basic need & do not depend on learning
(food, water, sleep)

Secondary Reinforcers Acquired or learned.
(money, grades, tokens, notoriety, attention)

34
Q

What is a positive reinforcement?

A

Presenting (adding +) a pleasant or desirable stimulus that will strengthen
B & increase probability of it occurring again.

35
Q

What is a negative reinforcement?

A

Removing (taking away -) a stimulus that will strengthen a B, and make it
more likely to occur again.

36
Q

What are reinforcers

A

Reinforcers are anything that follows a B that increases the likelihood that B will occur again.

37
Q

What is extinction in terms of OC?

A

Occurs in OC when reinforcement is withheld

38
Q

What is generalization is terms of OC?

A

Occurs when a response is made to a reinforcer similar to reinforcer that conditioned original response.

39
Q

Shared terms between OC and CC

A

Extinction, generalization, spontaneous recovery

40
Q

What is continuous reinforcement?

A

Fixed, Each correct response reinforced. Most efficient way to condition a response Shaping
Reinforcing successive approximations of desired response. Particularly for new and/or complex B’s.

41
Q

What is partial reinforcement?

A

variable

Correct responses reinforced randomly or intermittently More realistic

42
Q

R after fixed number of correct responses falls under which schedule of reinforcement?

A

Fixed Ratio

43
Q

R after a varying number of correct responses falls under which schedule of reinforcement?

A

Variable ratio

gives high response rate, resistant to extinction

44
Q

Fixed interval reinforcement

A

R after a specific time interval has passed.

Response increases near time of R, then slight drop. Ex: salary

45
Q

Variable interval reinforcement

A

R after a varying amount of time.

Lower but steady response. Ex: Pop Quiz

46
Q

What are factors that influence OC?

A

Magnitude of R, Immediacy of R, level of motivation of the learner

47
Q

What does a punishment do?

A

Follows a B, & decreases probability of B occurring again.
Addition (+) of an unpleasant stimulus or Removal (-) of a pleasant stimulus

48
Q

The disadvantages of punishment

A

It only suppresses bad behaviour, doesn’t help develop acceptable behaviour
also can create fear or hostility towards punisher

49
Q

What is learned helplessness?

A

Passive resignation to aversive conditions learned by repeated exposure to circumstances perceived as inescapable & unavoidable

50
Q

Overmeier & Seligman (1967)

A

Experimental group: dogs were strapped down and given electric shocks.
Dogs were then put in a new setting where a warning signal would indicate an electric shock; this time there was the possibility of escape.

51
Q

Most behaviours results from which conditioning?

A

a combination of both

52
Q

Applications of operant conditioning?

A

Behaviour Modification and token economy

53
Q

What is observational learning?

A

‘Modelling’; Learning from observing B

54
Q

What does observational learning do?

A

strengthens or weakens existing responses

55
Q

What does observational learning require?

A

Attention, retention, reproduction (requires motivation), reinforcement (if model is reinforced)
