Q

What is a weakness of introspection?

A

1) doesn’t explain how the mind works - relies on people describing thoughts + feelings (usually isn’t objective)
2) doesn’t provide reliable data - people are reporting their experiences which can’t be confirmed

Q

What are the arguments for psychology being a science?

A

1) psychology has the same aims as a science - predict/understand/control
2) behaviourist/cognitive/biological approaches use scientific procedures to investigate theory - controlled + unbiased

Q

What are the arguments against psychology being a science?

A

1) other approaches in psychology that don’t use objective methods to study behaviour - unreliable (can be biased + interpreted differently by different researchers)
2) hard to get representative sample of population for a study - findings can’t be generalised
3) experiments open to extraneous variable such as demand characteristics - hard to control

Q

How did Pavlov investigate classical conditioning?

A

1) dogs salivate when seeing food - reflex action
2) food=unconditioned stimulus
3) salivation=unconditioned stimulus
4) when Pavlov gave food, he would ring a bell
5) after several times, rang bell without giving food
6) bell alone caused salivation
7) bell=conditioned stimulus
8) salivation=conditioned response

Q

How did Skinner (1938) show operant conditioning using rats?

A

1) created a ‘Skinner box’ + placed one rat in at a time
2) Skinner box contained different stimuli - speaker/lights/floor which gave electric shock/food dispenser (released food when lever was pressed)
3) hungry rat placed in Skinner box
4) time taken for rats to learn that pressing lever would release food was recorded

Q

What were the findings of Skinner (1938) where he showed operant conditioning using rats?

A

1) rat would run around cage until it accidentally pressed lever + was rewarded with food
2) the more the rat was put back into the box, the quicker they got at learning where the lever was
3) rats found pressing lever could prevent something unpleasant - avoid receiving electric shock

Q

What is a weakness of conditioning?

A

1) most research involves animals - generalising to humans is difficult
2) more research into human conditioning would be useful different
3) species have different capacities for learning by conditioning
4) some species may learn by simple observation - no reinforcement needed
5) genetics influence + limit what different species can learn by conditioning
6) experiments into learning in animals may be seen as unethical - researchers must conduct cost-benefit analysis of whether it’s acceptable to use animals + they must ensure any animals are well looked after

Q

What is a strength of operant conditioning?

A

1) token economy used in institutions such as prisons + hospital for behaviour modification - appropriate behvaiour rewarded with tokens which can be exchanged for priveleges
2) token economy used to treat patients with schizophrenia found their behaviour become more appropriate
3) Skinner (1938) - highly controlled conditions used to discover cause + effect relationship between variables
4) nurture side of nature/nuture debate - learning occurs due to environmental factors + external stimuli rather than nature + biology (manipulating environmental factors can have effect on learning + behaviour)

Q

What is a weakness of operant conditioning?

A

1) Skinner (1938) - ignores free will (suggest past experiences involving operant conditioning will affect future behaviour + animals/people have no control over actions or behaviours)
2) Skinner (1938) - unethical (rats + pigeons placed in Skinner box in stressful conditions which could have negative effect on psychological + physical health of animals)
3) Skinner (1938) - results gained from animals + may not be applicable to humans
4) ignores biological approach - behaviour is not learnt but heavily influenced by genes/hormones/bichemical + neural mechanisms
5) other approaches must be considered when examining influences upon behaviour
7) cannot explain all behaviours (do people learn how to be aggressive?)

Q

What is modelling?

A

1) observing another person (model) - to learn behaviour

2) can be live/symbolic

50
Q

What factors affect successful imitation?

A

1) characteristics of model (age/gender)
2) observers perceived ability to perform behaviour
3) observed consequence of behaviour

51
Q

What is identification?

A

1) extent to which observer relates to model
2) extent to which observer feels they are similar to model + could experience same outcomes
3) children more likely to identify with model of same sex for social learning to be effective

52
Q

What is vicarious reinforcement?

A

1) seeing others rewarded for behaviour influences someone in whether they choose to imitate behaviour
2) people do not need rewards/punishments to learn new behaviours

53
Q

How is behaviour mediated?

A

Through cognitive processes (mediational processes)

54
Q

What are the mediational processes?

A

1) attention
2) retention
3) reproduction
4) motivation

55
Q

What happens in attention?

A

Notice role model, give full attention + attend to behaviour of model

56
Q

What happens in retention?

A

Remembering behaviour that has been modelled

57
Q

What happens in reproduction?

A

1) judge whether you have the ability to reproduce behaviour

2) if you can reproduce behaviour you’re more likely to do it

58
Q

What happens in motivation?

A

1) evaluate direct/indirect results of imitating behaviour

2) if behaviour results in good reward, you’re more likely to imitate it

59
Q

How did Bandura (1961) show that behaviour is learnt?

A

1) 36 boys + 36 girls with mean age of 52 months took part in study
2) 1st condition - children observed aggressive adult models playing with a Bobo doll (hitting with mallet)
3) 2nd condition - children observed non-aggressive models playing with other toys + ignoring Bobo doll
4) 3rd condition - control condition where children had no exposure to model
5) behaviour observed for 20 minutes

60
Q

What were the findings of Bandura et al (1961)?

A

1) children exposed to aggressive models imitated aggresive behaviour
2) children exposed to non-aggressive models did not show aggressive behaviour
3) aggressive behaviour slightly higher in control condition than non-aggressive condition
4) boys more aggressive than girls - imitation greatest when model same gender as observer

61
Q

What does Bandura et al (1961) suggest?

A

1) aggressive behaviour is learned through imitation of others behaving aggressively
2) reinforcement not needed for learning - we can learn just by observing

62
Q

What is a strength of Bandura et al (1961)?

A

1) provides evidence for social learning theory

2) strict control of variables - relaiable results + can be replicated

63
Q

What is a weakness of Bandura et al (1961)?

A

1) low ecological validity - not a natural situation
2) limited sample studied - hard to generalise results (infants from same school)
3) unethical - encouraged aggression in children

64
Q

What is a strength of the social learning theory?

A

1) criminals engage in more criminal behaviour when exposed to criminal model they highly identify with - positive outcome for committing crime increases likelihood observer will do the same
2) when observer played computer game with model that looked similar to themselves, they were more likely to engage in same behaviours as model
3) recognises importance of behavioural + cognitive factors when examining how new behaviours are learnt - unlike classical + operant conditioning

65
Q

What is a weakness of the social learning theory?

A

1) does not take into account cause + effect - young people who have deviant attitudes seek peers with similar attitudes rather than become deviant because of peers
2) ignores role of biology in behaviour - boys more aggressive than girls regardless of experimental situation (could be because of testosterone)

66
Q

What is the cognitive approach?

A

1) looks at internal workings of mind

2) explains behaviours through cognitive processes

67
Q

How do cognitive psychologists explain behaviour?

A

By looking at:

1) perception
2) language
3) attention
4) memory

68
Q

What is ecological validity?

A

Measure of how much the result of an experiment reflects what would happen in natural settings

69
Q

What are schemas?

A

Mental representations of experience/knowledge/understanding

70
Q

Why are schemas useful?

A

1) help organise + interpret information in brain
2) allow us to take shortcuts when interpreting vast amounts of information on a daily basis
3) help fill in the gaps in the absence of full information

71
Q

What are theoretical models?

A

1) simplified representations based on current research evidence
2) pictorial
3) represented by boxes + arrows that indicate cause + effect in mental processes

72
Q

Describe a computer model.

A

1) brain = processor
2) brain has data input + output
3) some parts of the brain form networks
4) some parts work sequentially - one process must finish before other starts (more demanding/unknown tasks)
5) parts can work in parallel (familiar tasks)

73
Q

What are the differences between human + computer models?

A

1) humans influences by emotional + motivational factors
2) humans have unlimited + unreliable memory - computers have limited + reliable memory
3) humans have free will

74
Q

What are the principles of the cognitive approach?

A

1) mental systems have limited capacity
2) control mechanism oversees all mental processes
3) two-way flow of information

75
Q

Ideas about the behaviour expected from someone in a certain role/setting/situation

76
Q

What are event schemas?

Information abut what happens in a situation

77
Q

What are self schemas?

A

Information about ourselves based on physical characteristics/personality/beliefs/values

78
Q

What is a problem with schemas?

A

Can stop people from learning new information

79
Q

How did Bartlett (1932) test + illustrate the idea of schemas?

A

1) English participants read Native American folk tale - unfamiliar with strange + unusual names/ideas/objects
2) story had different structure to average English story
3) participants asked to recall story after different lengths of time

80
Q

What were the findings of Bartlett (1932)?

A

1) all participants changed story to fir own schemas
2) details became more English + details/emotions added - English culture
3) as the length of time between reading + recalling increased, amount of information remembered decreased

81
Q

What is cognitive neuroscience?

A

1) scientific study of neurological structures/mechanisms/processes/chemistry responsible for thought processes
2) integration of cognitive + biological processes

82
Q

What methods does cognitive neuroscience use?

85
Q

What is neuroimaging?

A

Pinpointing areas of the brain which are active when a task is performed

86
Q

What is a strength of the cognitive approach?

A

1) considers mental processes - often overlooked in other approaches
2) big influence on development of therapies
3) many applications in different areas of Psychology - helps psychologists understand how people form impressions of others + how people might form cognitive errors + biases
4) used to explain development of faulty negative thinking - aids understanding of depression
5) emphasises scientific methods - high levels of control/cause + effect relationships can be identified

87
Q

What is a weakness of the cognitive approach?

A

1) research often lacks mundane realism - carried out in artificial situations + role of emotion/influence from other people ignored (results may not be valid)
2) fails to take individual differences into account - assumes everyone processes things in the same way
3) uses computer models - computers do not make mistakes/ignore available information/forget what has been stored on hard drive (humans do)
4) tells us how cognitive processes take place but not why they take place

88
Q

What does the biological approach look at?

A

1) genetic bases of behaviour
2) chemical changes in nervous system
3) hormonal changes

89
Q

What is heredity?

93
Q

What is phenotype?

A

The physical characteristic genes produce

94
Q

What does Darwin’s theory of evolution suggest?

A

1) over time individuals better adapted to environment through better genes are more likely to survive to reproduce
2) individuals less well-adapted are less likely to survive to reproduce + pass on genes
3) through natural selection, early humans became better adapted to their environments

95
Q

What percentage of their genes do identical twins share?

A

100%

96
Q

What percentage of their genes do non-identical twins share?

A

97
Q

What did Gottesman (1991) find from his meta-analysis of twin studies?

A

1) having an identical twin with schizophrenia gave you a 48% chance of developing it
2) having a non-identical twin with schizophrenia gave you a 17% chance of developing it

98
Q

What was the conclusion of Gottesman (1991)?

A

Schizophrenia has a strong genetic basis

99
Q

Evaluate meta-analysis of twin studies carried out by Gottesman (1991).

A

1) field studies - high ecological validity

2) only half of cases would develop schizophrenia - another factor must be involved

100
Q

How did Heston (1966) carry out an adoption study of schizophrenia?

A

1) studied 47 adopted children whose biological mothers had schizophrenia
2) control group of 50 adopted children whose biological mothers did not have schizophrenia
3) children followed up as adults + given intelligence/personality test

101
Q

What did Heston (1966) find after carrying out an adoption study of schizophrenia?

A

1) from experimental group, 5/47 became schizophrenic
2) from control group, 0/50 became schizophrenic
3) 4 from experimental group classified by borderline schizophrenic

102
Q

What was the conclusion of Heston (1966) when he carried out an adoption study of schizophrenia?

A

Supports the view that schizophrenia has a genetic basis

103
Q

Evaluate Heston (1966) when he carried out an adoption study on schizophrenia.

A

1) data could be affected by social desirability bias
2) interviews good way of getting data in naturalistic way
3) mother’s who didn’t suffer from schizophrenia may not have shown any symptoms yet

104
Q

How did psychologists investigate brain structure + function before brain-scanning techniques were developed?

A

Relied on case studies of people who had experienced brain injury/brain operations

105
Q

Give an example of a case study used to investigate brain structure + function.

A

1) Phineas Gage damaged part of his frontal lobe after an explosion at work - iron bar went straight through head
2) after accident he was less organised/more impulsive/experienced personality changes including increased aggression
3) led to belief that this area is responsible for these behaviours

106
Q

What is a weakness of using case studies to investigate brain structure + function?

A

1) studies are of one person - can’t generalise results
2) studies aren’t conducted in controlled circumstances - less scientific
3) unethical to inflict brain injury on humans
4) difference between non-human animal brains + human brains - results may not be useful

107

A

1) MRI scans from 16 licensed male London taxi drivers compared with control group who had never used taxis
2) all participants in good general/neurological/psychiatric health + average age of 44
3) all taxi drivers working for at least 18 months

Q

What did Maguire et al (2000) find after using MRI scans to show changes in brain structure?

A

1) average size of right posterior hippocampus significantly larger in taxi driver group
2) increased size relative to length of time driver had worked - longer working, larger the right posterior hippocampus

Q

What is the conclusion of Maguire et al (2000) after using MRI scans to show changes in brain structure?

A

Hippocampus is responsible for storing spatial representation of environment - specific navigational demands on taxi drivers resulted in physical damage

116
Q

Evaluate Maguire et al (2000).

A

1) findings could help those with brain injuries - size of structures can be influenced through cognitive activity
2) rehabilitation could be tailored to specific needs of individuals + injuries
3) good level of control + could be replicated - increases reliability
4) small sample size
5) results can only be generalised to male taxi drivers in London

Q

How has brain structure been used to investigate aggression?

A

Lesioning areas of brains of cats led to changes in levels of aggression - suggests hypothalamus + amygdala involved in aggression

118
Q

How has brain structure been used to investigate memory?

A

HM was unable to use long-term memory effectively - suggests hippocampus has important role

119
Q

How has brain structure been used to investigate psychopathology?

A

Finding of differences in prefrontal cortex when comparing people with + without schizophrenia - suggests relationship between them

Q

What is a strength of the biological approach?

A

1) can provide evidence to support/disprove a theory - very scientific
2) practical applications of biological approach in real world - biological treatments can be developed to help individuals
3) scientific method - highly controlled/replicable/increased reliability
4) people with knowledge of their genetic predisposition for a mental disorder can avoid environmental situations likely to trigger it/develop coping mechanisms to protect them

121
Q

What is a weakness of the biological approach?

A

1) doesn’t taken into account influence of environment/family/childhood experiences/social situation - more important in other approaches
2) can lead to individuals/groups taking personal/social responsibility for behaviour
3) reductionist - cannot fully understand behaviour without taking into account all the different factors that influence it
4) suggestion of genetic basis for criminal behaviour could lead to screenings of populations to identify genetic susceptabilities
