A
  • all behaviour is learnt
  • all behaviour can be learned
  • can generalise from animal behaviour to humans
  • we are born as a blank slate —> do not inherit anything

Q

what research went into classical conditioning?

A

pavlovs—> dogs have reflex response to produce salvia when they see food. Then pavlov rang a bell each time he gave them the dogs food which he repeated. then dogs began to salivate just when they heard the bell

Q

what is a issue of the behaviourist approach?

A
  • deterministic view of behaviour—> never actively chooses our behaviour so it gives us no free will
  • too much of a mechanistic view of humans

Q

what are 3 assumptions the social learning theory believe in?

A
  • all human behaviour is learned within a social context - role models
  • reinforcement may be inclined as well as direct - learn by people getting praised / punished
  • mental / cognitive processes are essential for learning to take place —> meditational processes

Q

what are the 4 mediational processes (ARMM)

A
  • attention
  • retention -how well behaviour is remembered
  • motor reproduction- how able the observer is to perform the behaviour
  • motivation - how much we want to perform the behaviour

Q

what are the strengths of the Bobo research?

A
  • all variables controlled as it was laboratory research - can determine cause and effect
  • high levels of replicability
29
Q

what are the weaknesses of the bobo research?

A
  • lacks ecological validity
  • only tells us about children
  • ethics
30
Q

what are more strengths of the SLT?

A
  • less mechanistic view - suggests there are thinking processes between observation and imitation
31
Q

what are some practical applications from the SLT?

A
  • age certificates for films / video games

- modelling —> used to treat anxiety or OCD

32
Q

what are the limitations from the SLT?

A
  • slightly reductionist —> only focuses on learning no attention to biology eg genetics eg in bobo doll research boys may naturally be more aggressive
  • difficult to measure influence of mediational processes
  • doesn’t explain all behaviour —> can’t model morality
33
Q

what are the assumptions made by the cognitive approach?

A
  • all behaviour derives from thinking processes
  • cognitive processes is affected by schemas
  • uses models —> theoretical & computer
34
Q

what is schema?

A

mental package of information we hold about the research these grow as our experiences do with the world

35
Q

how can schemas help us?

A

allows us to fill gaps in memory

can help us reach decisions quickly

36
Q

how can schemas negatively help us?

A

we may mistakes in our memory by trying to fill in the gaps

37
Q

what is a theoretical model used in the cognitive theory?

A

multi store model of memory

38
Q

what about a computer model?

A

mind is compared eg. input - process - output

39
Q

what are the strength of the cognitive approach?

A
  • research to support the claims - bugelski and alampay - ray man study - makes assumptions more believable
  • study uses humans rather than animals - more valid
40
Q

what practical applications does the cognitive approach have?

A

CBT—> successful therapy for mental health

41
Q

what are the limitations of the cognitive approach?

A
  • too mechanistic - reduces humans down to computers
  • making inferences - may be a leap too far in explaining as it’s only an estimation
  • tells us thoughts cause behaviour but doesn’t tell us where they originate from
42
Q

where is the broca in the brain and what is it responsible for?

A

left hemisphere at the front —> allows us to produce speech

43
Q

where is wernickes area and what is it responsible for?

A

left hemisphere right at front —> involved in understand speech

44
Q

what is the frontal lobe responsible for?

A

responsible for conscious though and decision making

45
Q

what part plays an important part in memory?

A

hippocampus

46
Q

what are the strengths of the cognitive neuroscience approach?

A

raire et al study - murder study - lower levels of activity their ore frontal cortex
—> wanted to scan children’s brains to prevent future crimes

47
Q

what are the practical applications from the cognitive neuroscience approach?

A

brain scanning techniques—> MRI and PET scans

-prefrontal cortex is activated when people feel guilty - brains scans to see it people are guilty in court

48
Q

what are the weaknesses of the cognitive neuroscience approach?

A

-socially sensitive issue - eg scanning children’s brains —> controversial

49
Q

what are the 4 parts of the biological approach?

A

genes, evolution, biological structure and neurochemistry

50
Q

what is the first assumption of the biological approach?

A

behaviour is influenced by our genes - gene responsible for a disorder is called a candidate gene - investigate this through twin studies which compares frequency of behaviour between identical and non identical twins

51
Q

how do we measure the frequency in twin studies?

A

concordance rate

52
Q

what are problems with twins studies?

A

cannot separate our genes from environment
limited generalisability
concordance rates are never 100%

53
Q

what is the second assumption of the biological approach?

A

genetically determined behaviour that improves an individuals survival will continue for further generation

54
Q

what is the third assumption of biological approach?

A

influence of neurochemistry on behaviour eg. seratonin too little = depression

55
Q

what is the fourth assumption of the biological approach?

A

schizophrenia have an abnormal structure of brain - enlarged ventrides

56
Q

what are the problems with 3 and 4?

A

difficult to determine cause effect —> which came first?

57
Q

what is a genotype?

A

specific genetic makeup of any individual

58
Q

what is a phenotype?

A

how the genes are expressed in physical and psychological characteristics

59
Q

what are the strengths for influence of genes of the biological approach?

A

research found concordance rate of MZ twins 68% where DZ Twins 31%

60
Q

what Are the problems for the influence of genes of the biological approach?

A

The concordance rate isn’t 100 percent so gene aren’t all responsible for abnormality for example it could be life experiences

61
Q

How does evolution influence our behaviour with the biological approach?

A

assumes that modern behaviour is the result of natural selection so genes are inherited for survival

62
Q

How can the brain scans show us a schizophrenic patient?

A

They will have enlarged ventricles

63
Q

What are the strengths for the role of evolution in the biological approach?

A

Humans hated bit of food because it was poisonous therefore we only like sweet food

64
Q

What are the problems of the role of evolution in the biological approach?

A

Lacks testability as it is impossible to test our evolutionary history therefore doesn’t meet the criteria for science

65
Q

What is the weakness of the biological structures in neurochemistry of the biological approach?

A

Difficult to determine cause and effect e.g. what came first did schizophrenia come first or in enlarged ventricles

66
Q

What is a strength of the biological approach?

A

Very scientific way of investigating behaviour therefore it greatly contributed to the emergence of psychology
help to develop drugs e.g. SSRIs for OCD

67
Q

What are the limitations of the biological approach?

A

Reductionist because it only looks his jeans not experiences
emotions or thought processes
deterministic approach because it doesn’t except humans make conscious decisions therefore guilty conviction could say that they couldn’t help their behaviour

68
Q

what are the 2 learning theories called?

A

behaviourist approach and social learning theory
