Q

how good is the evidence for classical conditioning

A
  • watson and rayner :
  • controlled environment = highly scientific and would have reduced environmental variables which could affect results

however :
- lacks ecological validity so doesn’t show how conditioning occurs in the real world

Q

comparisons and limitations to classical conditioning

A
  • explains involuntary reflexes which other theories don’t
  • reductionist - ignores influence of biology and focuses on nurture factors
  • suggests we don’t have a choice - determinist, when we are conditioned which may not be true as people choose to overcome fears

Q

operant conditioning lovaas theory

A
  • used behavior modification to treat children with autism
  • therapy of reinforcement and punishment
53
Q

weaknesses operant conditioning

A
  • ethics
  • fails to consider intrinsic motivation
54
Q

operant conditioning ethics

A

behavior modification gives therapists power to determine behavior of patients

open to abuse not protected from harm

  • animals used in experiments may be distressed
55
Q

how does operant fail to consider intrinsic motivation

A
  • properties of reinforcement provide complete account of human motivation
  • reinforcement is linked to extrinsic motivation which are outside factors
  • but we can also be intrinsically motivated by our own enjoyment
56
Q

is classical conditioning voluntary or involuntary

A

involuntary, NS causes UCS

57
Q

is operant conditioning voluntary or involuntary work responses

A
  • voluntary - behavior is associated with consequence
58
Q

what is the role of the learner in classical conditioning

A

passive - learner internalizes their natural environments and learns information

59
Q

role of learner operant conditioning

A

involved active participation of the learner - consciously changing behavior

60
Q

timing of stimulus classical conditioning

A

interval between C + UCS

61
Q

timing of stimulus operant conditioning

A

reinforcement schedule dictates when and how often behavior will be reinforced

62
Q

what was the aim of vaughan et al study

A
  • researchers wanted to find out about urination of cows and defactation habits of cows
  • used both operant and classical conditioning to see if they could get cows to urinate in a specific place
63
Q

sample vaughan et al

A

24 cows
12 calves given UCS of a diuretic which caused USR of ruination

12 calves milk allowance was cut to make milk a better reward -

64
Q

how were the 12 cows classically conditioned

A

given diuretic which caused UCR of urination
cows were given diuretic in the stall which made them urinate in the stall

when diuretic was no longer used cows were conditioned to urinate in stall

65
Q

how were 12 cows operant conditioning

A

12 calves milk allowance was cut to make milk a better reward
when calf urinated bell rang and they were given milk as a reward whenever they urinated in the stall

66
Q

vaughan et al which condition worked better ?

A

operant conditioning

67
Q

strengths of evidence operant conditioning

A
  • highly scientific
  • well controlled environment
68
Q

weakness of experiments operant conditioning

A
  • lacks ecological validity
  • often uses animals which can’t always be generalized to humans
69
Q

limitations of operant conditioning

A
  • ignores cognitive processes such as specific behavior patterns
  • reductionist - ignores influence of biology
70
Q

what is the social learning theory

A

learning occurs through observation someone we look up to or relate to (role model) after we observe behavior we can imitate them

71
Q

what characteristics are important for a role model ?

A

whether they are of high status
if they share similar characteristics or interests
same gender
similar age

72
Q

what factors affect imitation

A
  • characters of the observer, self esteem, self efficacy
  • consequences of behavior of the model, whether they are rewarded or punished
73
Q

what is vicarious learning

A

we learn through others mistakes or successes

74
Q

vicarious reinforcement

A

when you imitate the behavior of someone who has been reinforced for that behavior

75
Q

example of vicarious reinforcement

A

avoiding hot water after seeing another person get burnt by it

76
Q

vicarious punishment

A

tendency to engage in a behavior is weakened after having observed negative consequences for another engaging in that behavior

77
Q

vicarious extinction

A

occurs when it is noticed that the person who has bdddn observed in engaging in a behavior jd no longer rewarded for that behavior

78
Q

what are the stages of social learning theory

A

observation / attention
retention
reproduction
motivation

79
Q

observation

A

active process through which observer chooses to focus their attention on the modeled behavior

80
Q

retention

A

individual must retain or store what they’ve seen

assisted by imagery or language and stored by mental images

81
Q

reproduction

A

person shows behaviors they have seen modelled

self efficacy is important here

82
Q

influence of self esteem social learning theory

A

people are more likely to copy role models who were similar to them, getting positive feedback

83
Q

influence of self efficacy social learning theory

A
  • having previous successful experiences, observing and imitating peoples responses
84
Q

motivation social learning theory

A
  • final stage, refers to incentive
    if reward is offered we are more likely to reproduce behaviors
85
Q

vicarious reinforcement

A

people learn new behaviors by observing and imitating others - a behavior is learnt by observing others being rewarded for it

86
Q

vicarious punishment

A

someone sees another person experience negative consequences of a behavior

87
Q

extrinsic motivation

A
  • if behavior is rewarded, something tangible
  • revolves around a physical outcome
88
Q

intrinsic motivation

A
  • inherent satisfaction that comes from within

3.g excitement

89

A
  • matched on levels of natural aggression before their experiment
97
Q

how were the children’s natural levels of aggression assigned

A
  • children’s nursery teacher and the experimenter rated their aggression levels out of 5 looking for physical and verbal aggression and aggression inhibition, towards objects
98
Q

who saw the aggressive model ?

A

6 - boys dee aggressive make model

101
Q

give examples of physical and verbal aggression the aggressive model showed the bobo doll

129
Q

conclusion bandura 1965

A
  • vicarious punishment reduces aggression however reinforcement is a more powerful influence on aggression
