Q

Weaknesses of classical conditioning (with eg)

A

-Some of Pavlovs details are open to question (he believed contiguity was essential in pairing NS and UCS

-Can only explain how a limited range of behaviours can be aquired (only reflex responses not complex chains of learned behaviour only a partial explanation)

Q

Q

Pavlov findings

A

-Forward pairings of NS and UCS elicited began salivation up to 9 seconds after CS presented

-No salivation with backward conditioning

-Extinction occurred after repeated presentation of CS without UCS- occasional spontaneous recovery

Q

Generalisability in Pavlov

A

Unclear- humans have different brain structure to dogs which may cause a different response

30
Q

Findings have useful applications

A

Eating problems such as obesity can be partially understood in terms of conditioned responses

31
Q

How can Pavlovs research be useful in society

A

Eg cigarette packets- creates association between UCS of distressing image, NS of cigarettes- CR of disgust and horror

32
Q

Pavlov evaluation conclusion

A

Deserves credit-discovered classical conditioning

Well controlled procedures were well controlled-conclusions supported later research

33
Q

When does learning occur

A

Voluntary behaviour is followed by consequence (reinforcer or punisher) increasing reinforcement or decreasing punishment

34
Q

Positive Reinforcement

A

Something pleasant given to continue a behaviour

35
Q

Negative Reinforcement

A

Something unpleasant taken away to continue a behaviour

36
Q

Positive Punishment

A

Something unpleasant given to stop a behaviour

37
Q

Negative punishment

A

Something pleasant taken away to stop a behaviour

38
Q

Primary reinforcement

A

Rewarding because they have biological significance eg. food water sex

39
Q

Secondary reinforcement

A

Rewarding because they are associated with or can be exchanged for primary reinforcers eg money

40
Q

Skinners box (1948)

A

-box containing food pellets which were reinforcers for behaviours eg rat pulling a lever

-some chambers electrified floors (punishers)

-Able to target behaviours

41
Q

Difference between classical conditioning and operant conditioning

A

Operant conditioning happens throughout our lives- can be used to modify social behaviour

42
Q

Nature vs Nurture

A

The extent to which behaviour can be explained by innate, genetic factors or by external environmental factors

43
Q

Behaviourist

A

Believing we are born with a blank slate and we learn almost everything

44
Q

Operant conditioning

A

Explains in terms of learning through consequences

45
Q

Operant conditioning evaluation-positives

A

There is evidence to support operant conditioning- eg skinner’s box demonstrating operant conditioning in animals-consistent findings

Useful applications in education and childcare

46
Q

Operant conditioning evaluation conclusion

A

Can explain a much wider range of behaviours than classical conditioning, including complex chains

47
Q

Why is operant conditioning an incomplete explanation

A

Cannot account for learning of new behaviours which the animal has never performed before or where behaviours originate

48
Q

Fixed ratio

A

Ever x number of behaviours reward is given

49
Q

Variable ratio

A

After unpredictable number of behaviours reward is given

50
Q

Variable interval

A

After unpredictable amount of times reward is given

51
Q

How can abnormal behaviours be explained through reinforcement schedules

A

Eg variable ratio can start addiction- reinforcement schedules experienced by some people and not others

52
Q

Behaviour modification

A

The use of operant conditioning techniques to change the frequency of behaviour eg sports therapy

53
Q

Shaping

A

A process of modifying behaviour by reinforcing successive approximation to a desired behaviour eg. language

54
Q

Examples of animals used in experiments

A

Pavlov’s research on salivation in dogs, skinner’s research on rats and pigeons And Harry Harlow (1959) experiment on infant rhesus monkeys and attachment

55
Q

Ethical guidelines for scientific procedures act (1986)

A

In UK, animal research must only take place in licensed laboratories with licensed researchers on licensed projects

56
Q

BPS guidelines

A

-confinement, restraint stress and harm minimised to reduce trauma

-different species considered to reduce pain and discomfort

-optimise research design to reduce number of animals used

57
Q

+ of using animals

A

-Most animals can be generalised to humans

-Less ethical issues

-Animals have shorter breeding cycles- easy to study effects over generations

58
Q
  • of using animals
A

-Not always justifiable to generalise from animals to humans

-Can be unethical

-Guidelines may not be effective

59
Q

Evidence for reinforcement schedules-evaluation

A

-Gary Latham and Dennis Dosset (1978)- mountain beaver trappers responded better to ratio pay (£4 every trapped animal)- firm evidence in supporting partial reinforcement

60
Q

Useful applications in behaviour modification

A

-forms of treatment eg schizophrenia

61
Q

How do reinforcement schedules fail to take into account intrinsic motivation

A

-only takes into extrinsic motivation (rewards) rather than intrinsic (interest and enjoyment)

62
Q
  • of reinforcement schedules
A

-therapists can determine future behaviours of clients-open to abuse

63
Q

+ of reinforcement schedules

A

therapist + client generally agree on what behaviours they are working towards

64
Q

Reliability

A

All procedures are the same for every participant-comparible

65
Q

Reductionism

A

Identifying individual variable that may contribute to a complex behaviour

66
Q

Internal validity

A

Extent to which a research study is testing what was intended

67
Q

Predictive validity

A

Extent to which a test actually is related to the behaviour you want to measure

68
Q

Ecological validity

A

Whether your study findings can be generalised beyond the research setting

69
Q

Empiricism

A

View that knowledge can only come through direct observation of experiment

70
Q

Falsification

A

The attempt to prove something wrong.

71
Q

Scientific process

A

Observation-theory-hypothesis-designed study-conclusion
