what is cog nuerosciecn e
relating mental processes to brain structure
outline flight of fight functions
-adrenaline releases from adrenal gland
-emergency response
-inc blood flow, oxygen running repairing muscles
inference
assumptions about mental processes that cannot directly be observes
how sd treat phobia
-gradual exposure
-anxiety hierarchy
-relaxtion training
why scans for ocd
low levels of neurotransmitters might be removed to quickly by impulses that have passed
what is meant by primary data
first hand data collected speicifally for the research carried out
briefly explain jow excitation and inhibition are involved in synpatic transmittion
1)neurotransmitters can either be excitory or inhibitory
2)if nueortptransmitters are excitatory then thepost synapytic neuorone is more likely to fire an impulse
ee3)if inhibitory then the post synptic neurone less likley to fire impulse
4)excisoty is summed the neuorne less likwly fire if inhibaorty and if excitaoryt more likely
outline two features of the cog approach
explain two lims of the cog approach
- Schema are the mental representation of experience and knowledge and understanding.
- Mental processes are information processing and the processing can be compared to that of a
computer. - Models can be used to provide testable theories about mental processing and these can be
studied scientifically and inferences made - The approach can be seen as mechanical in regarding human thinking as processing like the computer leaving little room for the irrationality seen in emotional behaviours
The focus on detail of exactly what can be recalled by participants in controlled environments means an understanding of everyday use of memory, for example, is missing from explanations. This leads to issues of generalisation.
briefly eva;uate rerieval failure as an explanation for forgetting
- use of evidence from studies showing context/state/category dependent forgetting, eg Abernethy
(1940), Godden and Baddeley (1975), Overton (1972), Peters and McGee (1982), Tulving and
Pearlstone (1966) suggest that retrieval failure/absence of cues is a valid explanation of
forgetting - application of explanation, eg improving memory using mnemonics, category headings; mentally
reinstating the context in cognitive interview improves EWT - context has to be very different in real life to have any effect
- context effect only occurs when memory is tested in particular ways: free recall vs recognition.
describe and eva;uate the muli store model of memory
- structural nature of the model
- sensory register, STM and LTM are separate, unitary memory stores
- characteristics of each store, eg capacity, duration and coding
- information passes from store to store in a linear way
- functioning/dynamics of the model, eg role of attention to pass info from SR to STM; rehearsal to
pass info from STM to LTM - explanations of forgetting are different for each store.
Possible evaluation points: - use of evidence to support the distinction between STM and LTM, eg HM, Murdock (1962),
Glanzer and Cunitz (1966), Beardsley (1997), Squire et al (1992) - use of evidence to contradict the model, eg KF, Clive Wearing, Tulving et al (1994)
- view of stores as unitary too simplistic – contrast with different types of STM/LTM
- static view of STM contrasted with active processing view of WMM
- discussion of maintenance versus elaborative rehearsal, eg Craik and Tulving (1975) showed
deep/elaborative processing creates longer memories than shallow processing - comparison/contrast with alternative models of memory.
other than ethical issues explain one limitation os using animals to study attachment in humans
- problems of extrapolation to attachment in human infants – what applies to non-human species
may not also apply to human infants - difference in nature and complexity of the bond
- human mothers show more emotional attachment to young than birds
- humans may be able to form attachments at any time
- DNA differences/human brain size differences may reduce generalisability
briefyly explain two ways the strange situation tecnique might be odified to be more relaitic
.measure attachment type in the home/a more familiar environment: to improve the ecological
validity of the measure of attachment type
* use different caregivers: to get a wider measure of baby’s attachment as most babies in real life
have multiple attachments
* make the observations covert: to ensure mother’s behaviours towards infant are more natural
(improve internal validity)
* make multiple observations over time as a more realistic assessment of usual attachment type
would be achieved.
discuss bowlbys theory of maternal deprivation
- Bowlby’s use of the term ‘deprivation’ – attachment disrupted or broken
- effects on development – intellectual, emotional, social, eg affectionless psychopathy,
delinquency, low IQ - critical period – an issue if prolonged separation, if before two and half years (but risk up to five
years) and if no substitute available - Bowlby’s theory of irreversibility – consequences cannot be reversed
- internal working model – this can lead to inability to be a good parent
- continuity hypothesis – if there are prolonged separations then there may be issues into
adulthood. - use of evidence to support or refute Bowlby’s work, eg Schaffer’s multiple attachments;
studies contradicting the critical period and reversibility, eg Rutter’s Romanian orphan
research, eg Lewis (1954) replication with large sample did not find separation from the
mother and did not predict criminality or difficulty forming close relationships - Rutter’s criticism that there could be an overstatement of the effects of deprivation
- Bowlby’s confusion over privation and deprivation
- sensitive versus critical period
- real-world application, eg the way children are cared for in hospital has changed as a
result of Bowlby’s theory/research
Explain one limitation of Zimbardo’s research into social roles.
ethical issues: lack of informed consent, whether or not the consent gained was sufficiently
informed; deception; lack of protection from psychological harm – participants soon
became distressed; whether or not the distress should have been anticipated; right to
withdraw was initially declined
give two behavioural chacteristicsnof phobias that would be seen in someoe who has a ohobia if dogd
- avoidance – Rita no longer going to her friend’s house where a dog might be encountered/Rita tries
not to leave the house in case she sees a dog on the street - freeze response/endurance behaviours – Rita cannot move until the dog has walked away
- panic behaviours – Rita shakes in the presence of her friend’s dogs
explain the process of synaptic transmission
- electrical impulses (action potentials) reach the presynaptic terminal
- electrical impulses (action potentials) trigger release of neurotransmitters (or named example) from
synaptic vesicles - neurotransmitters diffuse across the synaptic cleft
- neurotransmitters bind to receptors on the postsynaptic membrane.
outline two ways in whic the psychologist might change thw design of this study to deal with this problems
- tell the teachers they would need to complete meditation or healthy diet for a week
- tell them they would have their heart rate measured at the beginning and end of the week
- explain they have the right to withdraw
- ask for agreement/obtain a signature.
outline what is meant my cog neuroscience
- scientific study of brain/neurological structures, mechanisms, processes, chemistry that are
responsible for cognitive/mental/thinking processes - the use of scanning techniques
- the study of neurotypical individuals to locate the physical basis of cognitive processes in the brain
- use of examples
outline and evaluate statistical infreqency and deviation from ideal mental health as definition of abnormality
statistical infrequency/deviation from statistical norms: abnormal behaviour is that which is
rare/uncommon/anomalous; this definition focuses on the quantity of behaviour measured in standard
deviations from the mean rather than the quality
* deviation from ideal mental health: absence of signs of mental health used to judge abnormality;
description of (Jahoda’s) criteria – accurate perception of reality; self-actualisation; resistance to
stress; positive attitude towards self; autonomy/independence; environmental mastery; the more
criteria someone fails to meet, the more abnormal they are.
- statistical infrequency/deviation from statistical norms: fails to account for behaviour that is statistically
rare but desirable such as having a very high IQ; some disorders are not statistically rare; issue of who
decides where the cut-off point is - deviation from ideal mental health: positive, holistic approach to diagnosis; criteria for mental health
are too demanding/unrealistic – most people would be judged abnormal based on this definition
because they would fail at least one criterion at some point; culture bias – many of the criteria reflect
Western cultural norms of psychological ‘normality’, eg value placed on independence/autonomy
briefly outline the dveiation from ideal mental health defiiton of abnormality
bnormality is the absence of criteria for good mental health (as in physical illness)
Jahoda proposed criteria of ‘optimal living’
identification/knowledge of criteria, eg. resistance to stress; accurate perception of reality; working
towards self-actualisation; positive view of self; lack of dependence on others; ability to adapt
the more criteria are absent, the more serious the abnormality.
evaluate the ffa for abnormality
a form of (indirect) observation that examines artefacts/communications/form of media that
people producePossible evaluation:
recognises the patient’s perspective/experience is important in defining abnormality
provides a threshold for professional help for those who need it most
failure to function may be a normal reaction to a traumatic event, eg a bereavement
can rely on a subjective assessment (though there have been attempts to make judgements more
objective, eg Global Assessment of Functioning)
can use more objective measures of failing to function adequately eg. poor attendance data at
school/work
some people appear to function perfectly normally despite being seriously ill/disturbed, eg Harold
Shipman; some depressed patients
overlap/comparison with other definitions, eg deviation from social norms.

ne ways researchers could have used content anlaysis to anylse diary extracts in invesigations
‘word/phrase/theme’ could be
counted/tallied/categorised
explain hw reloiability oof contrnt analuss coild be improvved
researchers should clarify/establish/agree/review operationalised codes/categories etc
researchers could create new categories if necessary (that are mutually exclusive)
