Q
  • briefly outline how two variables investigated by asch were found to affect conformity 2mrks
A
  • increasing the size of the majority increased conformity
  • increasing task difficulty increase conformity
  • presence of a dissenter who did not conform reduced conformity
  • withdrawal of a dissenter led to increased conformity
  • writing the answer down reduced conformity
  • individual differences eg highly confident individuals conformed less

Q
  • Describe the phonological loop component of the working memory model 3mrks
A
  • one of slave systems controlled by CE
  • deals with auditory/sound info or deals with both written and spoken material
  • can be subdivided into phonological store (inner ear) & articulatory process (inner voice)
  • the phonological store stores the words you hear (in speech form)
  • the articulatory process allows for maintenance rehearsal
  • has limited capacity/the capacity of the loop is what can be said in 2 seconds

Q
  • discuss Wundts role in the emergence of psychology as a science 3mrks
A
  • first to open a lab designated to the scientific study of psychological enquiry under controlled conditions facilitating accurate measurements and replication
  • focus was on trying to understand psychological processes of perception etc structuralism rather than philosophical or biological processes
  • he later recognised that higher mental processes were difficult to study using his procedure and this encouraged others to look for other methods and techniques paving the way for approach eg scanning
  • introspection still used today in areas such as therapy and studying emotional states demonstrating its value as one way mental processes can be investigated
  • issues of determinism and predictability could be presented as a strength or a limitation

Q
  • Identify two glands that form part of the endocrine system and outline their functions 4marks
A
  • thyroid gland- secretes thyroxine/increases metabolic rates and affects growth
  • adrenal glands-secretes adrenaline/controls the sympathetic division in the fight or flight response
  • pituitary gland-causes other glands to secrete their hormones or directly produces effects eg causing the breasts to lactate

Q
  • outline the use of one or more drugs in the treatment of ocd 4mrks
A
  • attempt to increase/decrease levels of neurotransmitters/activity of neurotransmitter in brain
  • general purpose is decrease anxiety, lower arousal, lower blood pressure or heart rate
  • antidepressants SSRIs prevent reuptake of serotonin & prolong activity in synapse in order to reduce anxiety/normalise the worry circuit
  • tricyclics-block the transporter mechanism that reabsorbs serotonin & noradrenaline again prolonging their activity
  • anti anxiety drugs -benzodiazepines-enhance the activity of GABA and therefore slow down the CNS causing relaxation
  • SNRIs -more recent drugs which also increase serotonin and noradrenaline and are tolerated by those for whom SSRIs are not effective

Q
  • Explain one reason why using schema might be useful when processing info from the world around us and one reason one reason why using schema might not be useful when processing info from the world around us 4mrks
A

Might be useful
- schema help us predict what will happen in our world based on our experiences
- schema enable us to process vast amounts of info rapidly
-schema help us form becoming overwhelmed by environmental stimuli
Not useful
-schema can distort our interpretation of sensory info
-schema lead to perceptual errors or inaccurate EWT/memories
-schema can caused bias recall/ see what we expect
-negative/faulty schema may have a negative impact on mental health

Q
  • Explain why neurons can only transmit info in one direction at a synapse 3mrks
A
  • synaptic vessels containing neurotransmitter are only released from presynaptic membrane
  • receptors for neurotransmitters only present on post synaptic membrane
  • it’s the binding of neurotransmitter to receptor which enables signal/ info to be passed/transmitted on (to the next neuron)
  • diffusion of neurotransmitters mean they can only go from high to low concentration so can only travel from the presynaptic to postsynaptic membrane

Q
  • The fight or flight response enabled our ancestors to survive but can be less helpful in response to more modern stressors. Explain how the body responds during fight or flight and why this could be unhelpful in a driving test situation 4mrks
A
  • fight or flight response causes adrenaline to be released which cause an increased production of sweat and faster heartbeat and breathing rate which could be off putting and unhelpful during a driving test eg sweaty hands may make it harder to grip the steering wheel
  • fight or flight response enable quick reaction to fight threat or run away from it but neither of these options would be helpful in driving test as if you ran away or attacked instructor you would fail test

Q
  • Julia complains that her baby is sleeping all day and keeping her awake all night. Using your knowledge of research into exogenous zeitgebers discuss what Julia could do to encourage her baby to sleep more at night 8mrks
A

Content: external cues act as exogenous zeitegebers eg klein & wegmann
-cues may influence/entrain endogenous pacemakers
-light suppresses production of melatonin from pineal gland which influences peoples sleep/wake cycle
Application: Julia should try to keep baby in dark at night eg shutting curtains & keeping lights off but expose baby to light in day time eg keeping curtains open go outside
-Julia should use social cues eg ensuring verbal communication, eye contact & feeding only in day time
Discussion: research to provide support for importance of light as a zeitgeber eg Campbell and Murphy, vetter et al, burgees et al
- use of research to provide evidence against importance of social cues as a zetigeber eg lughton miles et al
-discussion for & against role of light as an exogenous zeitgeber
-counter arguments eg role of endogenous pacemakers -biological clock

Q
  • Briefly outline and evaluate normative social influence as an explanation for conformity. 4mrks
A

-A01people agree with opinion of majority so to be liked & gain acceptance/avoid rejection/avoid ridicule
-often leads to compliance-people agree publicly with group but privately don’t change personal opinion
A03-evidence support eg asch-when interviewed afterwards participants said they conformed to avoid rejection by others
-individual differences-how much people want to be liked by others &therefore not everyone will conform due to this desire
-other explanations eg ISI, conformity to social roles, social identity theory

Q
  • Memory studies are sometimes criticised for being unrealistic. Briefly explain two ways that this criticism could be addressed in memory research. 4mrks
A
  • researchers could use natural environments for participants like school classrooms when learning & recalling info
  • researchers could ensure tasks are everyday tasks for their participants such as learning definitions if they are student participants
  • realistic stimuli can be used to recall info such as visual tasks so that they more closely reflect everyday memory tasks
  • different methodology/ data collection techniques

Q
  • outline bowlbys theory of maternal deprivation 3 marks
A
  • deprivation definition
  • effects on development-intellectual, emotional, social eg affectionless psychopathy, delinquency, low IQ
  • critical period-issue if prolonged separation, if before 2 and a half years ( but risk up to 5 years) and if no substitute available
  • internal working model-can lead to inability to be a good parent
  • continuity hypothesis- if there are prolonged separations then there may be issues into adulthood

Q
  • explain one strength and one limitation of a reductionist approach in psychology 4 marks
A

-strengths- studying basic units of behaviour adds weight to scientific research
-more objective to consider basic components of behaviour
-leads to greater clarity of understanding at chemical, cellular level
-better able to isolate cause when studying basic units of behaviour eg can see which chemicals are implicated in certain behavioural disorders then may be able to affect treatments
-parsimonious- simplest explanation often the best
Limitations
-simplistic & ignores complex interaction of many factors
-leads to us losing sight of behaviour in context
-less able to understand behaviour because we do not understand it’s meaning-loss of validity
-ignores emergent properties/distracts from a more appropriate level of explanation

    -bowlbys research and the effects on child rearing/ working mothers
    -diagnosis of depression/ schizophrenia
    -labelling eg gender identity
    -biological research into addiction/aggression/offending- issue of who is to blame eg if offending/aggression/addiction is inherited
    -piagets research into discovery learning-changes in educational system/classroom practice
    -implications of relationship counselling based on research into relationships
    -how research into gender might affect parenting/educational practice
    Discussion: evidence to explain/elaborate/analyse the implications
  • how researchers have dealt with the implications
    -cost/benefit discussion eg consideration of whether the benefits of publication outweigh the costs
    -short term cost (at time of publication) vs long term gain ( in years to come and for future generations)

Q
  • Outline social learning theory as an explanation for gender development.explain one strength of social learning theory as an explanation for gender development 6mrks
A
  • SLT explains gender development in terms of socialisation and experience
    -involves observation and imitation of same sex role model eg parents, older siblings, TV characters
    -identification with same sex model is more likely if model is attractive, high status,similar etc
  • vicarious reinforcement is important eg child sees others rewarded for what is seen as sex appropriate behaviour and therefore imitates
    -mediational processes are involved eg attention, retention etc
    Strengths
    -use of evidence to support social learning explanations for gender eg evidence that young children do copy same sex models
  • SLT is consistent with findings that gender related behaviours differ across cultures
    -consistent with findings that suggest media influence in gender behaviour

Q

Outline techniques used in the cognitive interview and discuss the effectiveness of those techniques on the accuracy of eyewitness testimony 8marks

A

-report everything – interviewer encourages witness to report all details about event, even if details may seem unimportant
-context reinstatement –mentally recreate image of situation,including details of environment,like weather conditions & individual’s emotional state including feelings at time of incident
-recall from changed perspective –mentally recreate situation from different POV eg describing what another witness present at scene wouldve seen
-recall in reverse order –witness asked to recall scene in different chronological order, eg from end to beginning.
Discussion
-how/why recall is enhanced,eg role of context reinstatement; work on reconstructive memory; use of context; makes event more meaningful
-Limitations, eg usefulness of cognitive interview with children; less useful when increased time between event & recall
-relative effectiveness of individual features of cognitive interview;better for recall of peripheral detail than central detail
-use of relevant evidence to support/refute argument, eg Kohnken et al (1999); Milne & Bull (2002).

Q
  • one explanation of forgetting/evaluation
A

Retrieval failure evaluation points:
-use of evidence, eg Godden & Baddeley suggests retrieval absence of cues is valid explanation of forgetting
-application of explanation, eg improving memory using mnemonics, category headings
-context has to be different in real-life to have any effect
-context effect only occurs when memory is tested in particular ways – free recall vs recognition
Interference
Possible evaluation points:
-use of evidence from lab studies, eg McGeoch & McDonald & real-life, eg Schmidt supports effects of interference
-application of explanation, eg avoiding similar material when revising for exams
-use of artificial materials in lab studies, eg recall of word lists
-deliberate attempt to induce interference in lab studies, eg by limiting time between learning & recall
-evidence suggests interference can be overcome using cued recall
-interference tends not to occur with experts

Q

STEM about two mothers and toddlers and their involvement
- discuss the learning theory of attachment and bowlbys monotropic theory of attachment.refer to the conversation above in your answer 16marks

A

Possible content: Learning theory
-emphasises importance of food in formation of attachment cupboard love/drive reduction
– children love those who feed them
-cc creates attachment –association of caregiver (NS) with food (UCS) causes conditioned response of pleasure
-operant conditioning strengthens attachment – crying positively reinforced by caregiver;
caregiver receives negative reinforcement when crying stops
Monotropic theory- importance of primary attachment figure – bond with mother-figure is unique
-more time spent with mother-figure,betterlaw of continuity;law of accumulated separation
-internal working model –first attachment is blueprint for future relationships;child forms mental representation
-importance of critical period
-role of social releasers
Possible application: Learning theory
-first mother’s view is consistent with principles of learning theory – her bond with her daughter based on breastfeeding/food
-husband’s bond with Millie isn’t as strong as she hasnt formed association with her
father & pleasure
Monotropic theory -second mother’s view is consistent with monotropic theory-bond with mother is unique & special
-she suggests maternal bond is ‘important for future development’=consistent with Bowlby’s view of internal working model
Possible discussion points: Learning theory
-plausible &scientific as founded in established theory
-reductionist –focus on basic processes (S-R links, reinforcement) too simplistic to explain
complex attachment behaviours
-evidence,eg Schaffer & Emerson -primary attachment figure not always person who feeds child
-environmentally deterministic- early learning determines later attachment behaviours
Monotropic theory
-evidence, eg Schaffer & Emerson -multiple & not monotropic attachments are norm
-concept of monotropy=social sensitive-places pressure on mothers &underestimates role of father
-evidence eg Bailey et al -concept of internal working model

Q

The sample used in this pilot study was an opportunity sample. Briefly explain how using a stratified sample when the final study is conducted might be an improvement to the design. 3marks

A
  • stratified sampling ensures each identified sub group of whole target population of possible participants represented in sample so generalisation of results to target population is more valid than if participants just available at time of asking
  • stratified sampling improvement because people who’re identified by opportunity likely to be present at same time, doing similar things, possibly similar personality types etc may limit representativeness of sample.

-identify strata/sub-groups in their population eg four different schools
-calculate required proportion from each stratum based on proportion in population
-select sample at random from each school/stratum/sub-group.
-use random selection method, eg assign each student a number then use computer,
calculator or random number table to select specified number of numbers between 0 and X (or hat method).

Q

Suggest two additional points that could be added to the debriefing statement to better ensure ethical treatment of the students. 4 marks

A
  • confidentiality: advise students data is kept confidential so individual responses will not be identifiable & will not be accessible to anyone other than researchers/their agents
  • withdrawal of data: ensure students told they have right to withdraw data after event even if consented to survey & aware of aim at start
  • protection from harm: ensure no one has been upset or offended by questions on survey, eg if they felt to be intrusive or offensive, or upset by feelings aroused during survey. If so, then discuss these feelings are normal etc
  • debrief: explain full purpose/aim of survey, check again they are willing to allow data used.

Q

Explain how social influence processes contribute to social change. 4 marks

A
  • content:minorities contribute to social change by being consistent, flexible & non-dogmatic. Through social crypto-amnesia & snowball effect, gradually minority turns into majority
  • influence of obedience, eg changes to laws which make certain behaviour more social norm which others then adopt
  • majority influence can occur through social norms/normative social influence
  • dictators can bring about social change through power & through process of obedience. This leads to groups of people changing their behaviour because of fear of punishment/consequences of not obeying
  • consistency contributes to social change when minority repeatedly gives same message. makes majority reassess belief & consider issue more carefully (may adopt minority POV)
  • commitment contributes to social change when minority show theyre willing to give up something for their belief majority take their argument more seriously (& may adopt it as their own)
  • flexibility/being non-dogmatic contributes to social change when minority show theyre willing to listen to other viewpoints majority listen to their POV/take their argument more seriously (& may adopt it as their own)
  • theories linked to minority influence, eg social impact theory, snowball effect, social cryptoamnesia
  • outlining how drawing attention, creating cognitive conflict, augmentation, identification with minority, appearance of objectivity or certainty of correctness as processes used by minorities can contribute to social change.

Q

Discuss two or more types of determinism. Refer to the case of Dancho as part of
your discussion. 16 marks

A
  • Possible content -determinism – general idea traits & behaviours are outside our control, due to factors either internal or external over which we have no control
    -biological determinism – idea traits & behaviours are governed by internal biological factors like genes, neurochemistry, brain structure & function
    -psychic determinism –idea traits & behaviours governed by unconscious instincts & drives, cause of behaviour is rooted in childhood experiences
    -environmental determinism – idea traits & behaviours governed by external forces like experiences, upbringing, learning, schools, parents, peers etc.
    -hard determinism – traits & behaviours entirely out of individual’s control
    -soft determinism – traits & behaviours determined by external or internal forces but
    an individual can still exercise some control, eg via thought processes.
    Possible application
    -biological determinism - Dancho’s musical ability may be genetic -inherited from his father who also plays piano well, Dancho appears to suggest his talent is innate ‘my earliest memories’, ‘music is a part of me’
    -environmental determinism – ability is product of learning from father, ability was nurtured at a specialist school from 4yrs, hrs of practice every day providing reinforcement, applause providing reinforcement
    -hard determinism – Dancho cant control his behaviour ‘Even if I wanted to stop…’.
    -psychic determinism – through Oedipus complex Dancho identified with pianist father
    Possible discussion -contrast with free will position people able to choose how to behaviour
    -soft determinism as compromise between hard determinism & free will -role of
    consciousness & subjective awareness
    -links with broad approaches in psychology eg behaviourism
    -role of single versus multiple causes
    -comparisons of different types of determinism
    -implications for science & emphasis on causes of behaviour–determinism fundamental to scientific focus on investigating causes & being able to predict behaviour
    -implications for child-rearing, eg role of parental expectations &implications for society, eg education, offending behaviour, addiction, economic implications etc
    -studies/theories to support or counter determinism Strengths/limitations of adopting a determinist stance.

Q

Referring to the comments about Ben and Dido, outline Turner’s syndrome and Klinefelter’s syndrome. [4 marks]

A

-Application to Ben -Ben is male – Klinefelter’s syndrome is chromosomal disorder occurring males with extra X chromosome XXY pattern)
-school problems mentioned by Ben’s mum include: problems reading & writing;a tendency to get upset/depressed easily;passivity compared to other boys
-physical differences referred by Ben’s mum include: extra height/long legs,small testes, lacking facial hair.
Application to Dido- Dido is female – Turner’s syndrome is chromosomal disorder occurring females missing X chromosome XO pattern
-effects at school mentioned by Dido’s mum include: good language skills/reading
-physical effects referred by Dido’s mum include: short stature, no breast development, short neck, later infertility.

34
Q

Discuss what psychological research has told us about atypical gender development.
[16 marks]

A

-Possible content:gender identity disorder (gender dysphoria) – mismatch between external sexual characteristics & psychological experience of self as male/female
-social explanations - operant conditioning, reinforcement - identification, imitation, modelling; gender identity individuals lack
stereotypical male role model (Rekers 1995)
-social-psychological explanations –extreme separation anxiety in males (psychoanalytic)
• cognitive explanations - development of non sex-typed schema (dual pathway theory).
• cultural variations e.g. third gender
• genetic explanation – twin evidence approx. 60-70% of variance in cross-gender behaviour
due to genetic factors (Beijsterveldt 2006) (Coolidge 2002); correlation between gender
identity disorder and variant of androgen receptor gene (Hare 2009)
• brain structure explanation - differences in hypothalamic area of gender reassignment
individuals post-mortem (Garcia-Falgueras and Swaab 2008); sexually dimorphic nucleus smaller (as in female brain) in gender dysphoric males; BSTc comparable size to typical female brain (Zhou 1995)
• hormonal explanation - imbalance due to abnormal levels of male hormone from testes in the womb
Possible discussion:
• counter-evidence, eg lack of continuity - counter to biological explanations experience of gender identity disorder for the majority is transient - few years only (Zucker 2008); few hormonal differences between gender identity individuals and other men (Gladue 1985)
• counter evidence e.g. psychoanalytic theory does not explain atypical development in females
• comparisons between explanations
• distinction between cross-gender behaviours and beliefs/behaviours
• issue of cause and effect – research cannot show causal influence
• broader issues, eg biological versus environmental determinism; reductionism of the
biological approach; nature versus nurture
• social implications – increasing acceptance of gender roles outside the traditional
male/female dichotomy
• problems of research – social sensitivity.

35
Q

Briefly discuss two limitations of the family dysfunction explanation for schizophrenia.
[6 marks]

A

-• ethical problems - parents feel responsible for their child’s illness causing even greater
stress and anxiety. Out-dated views that were once accepted are no longer tolerated by
families and are now seen as destructive rather than productive
• unreliability of recall leading to data that may lack validity – patients report childhood
experiences retrospectively. Recall may be inaccurate and distorted by the need to explain.
Prospective evidence is rare
• family dysfunction may be the result of the child’s disturbing behaviour rather than the
cause – impossible to show cause and effect
• discussion of limitations via comparison with alternatives, eg ample evidence that there is a
biological cause
• family dysfunction might act as a trigger but the basic cause is biological (dopamine
hypothesis, genetic evidence)
• counterargument to the limitation given.

36
Q

Outline and evaluate the use of antipsychotic drugs to treat schizophrenia.[8 marks]

A

-Outline:
• typical antipsychotics (eg chlorpromazine) are dopamine antagonists reducing dopamine
activity by blocking dopamine receptors at the synapse. This reduces positive symptoms
such as hallucinations and has a calming/sedative effect
• atypical antipsychotics (eg clozapine and risperidone) block dopamine receptors and also
act on other neurotransmitters eg acetylcholine and serotonin; also address the negative symptoms such as avolition.
Possible evaluation:
• use of evidence re effectiveness in reduction of symptoms and/or relapse rates, eg
Thornley 2003
• side effects – typical antipsychotics: dry mouth, constipation, lethargy and confusion,
involuntary muscle movement - tardive dyskinesia; atypical antipsychotics: weight gain,
cardiovascular problems, agranulocytosis (autoimmune disorder affecting white blood cells)
• comparison of effectiveness, eg atypical antipsychotics v typical antipsychotics, eg Bagnall
2003, Marder 1996
• comparison with other treatments, eg cognitive therapy, family therapy
• need to assess long-term benefits – many studies focus on short-term effects only
• enhanced quality of life: for patients who can live independently/ outside of institutional
care; for family members
• economic implications eg cost in relation to other treatments/ hospitalisation; analysis of benefit re ability of patient to return to work.

37
Q

Briefly explain the top-down approach to offender profiling.

[2 marks]

A

-conceptual categories/templates of organised and disorganised offender are pre-existing in the mind of the profiler
• evidence from the crime scene and other details of the crime/victim/context are then used to fit into either of the pre-existing categories and determine the offender as one type or the other.

38
Q

Explain how the psychologist could continue her investigation by carrying out thematic analysis of the interview recordings.
[2 marks]

A

-use the recordings to make a transcription of the interview
• use coding to initially analyse the transcripts
• review the transcriptions/codes looking for emergent themes/ideas that might be linked to
violent crime eg family violence, parental argument, alcohol misuse

39
Q

Outline the fight or flight response. 3 marks

A

-hypothalamus prepares body for action response release of adrenaline from adrenal gland
-Triggers from parasympathetic to sympathetic activity and back again.
-effects of adrenaline, eg increase heart rate
–constricts blood vessels, increasing rate of blood flow & raising blood pressure
– diverts blood away from skin, kidneys & digestive system
– increases blood to brain & skeletal muscle
– increases respiration and sweating.

Q

Write a brief explanation of inference that would help Adil to understand what his
teacher means. 2 marks

41
Q

Describe and evaluate the social learning theory. Refer to the conversation above
as part of your answer.
AO1 = 6, AO2 = 2 & AO3=4. 12 marks

A

A01 -learning takes place in social context
-learning occurs via observation of behaviour of others & rewards or punishments received for behaviour – vicarious reinforcement
-other people act as models & characteristics of models influence likelihood of imitation of behaviour
-learning & performance are not same activity
-mediational processes, eg attention, retention, motivation, reproduction, affect production of
behaviour
-reciprocal determinism & concept of free will
-concept of identification.
A02- Samira commenting on John’s little sister copied how John uses mobile phone. illustrates number of possible SLT behaviours: observational learning, imitation, modelling, identification & even internalisation
-John commenting on how behaviour can be learned by indirect reinforcement/vicarious reinforcement – seeing someone punished for a behaviour decreases likelihood of behaviour being imitated.
A03-evidence support SLT eg Bobo doll study
-benefits of experimental approach to investigate SLT & issues with experimental evidence might affect validity of results & therefore conclusions drawn
-focus on human traits of consciousness & rationality which can’t be demonstrated with animal research, addresses influence of mediational processes on learning–neglected by behaviourists
-provides explanations relate to behaviours like aggression & intellectual development
-doesnt pay much attention to impact of biological, heredity or maturational factors on
behaviour, evidence from these areas of research show they do have impact.
-can account for cultural differences in behaviour.
-valid comparison with other approaches.

42
Q

How might the biological approach be used to explain Bob’s obsessive-compulsive disorder
4 marks

A

-Neural explanations: neurochemical & neurophysiological –Bob having scan.
-basal ganglia & other circuits been implicated suggesting disturbed communication
in these structures might account for repetitive behaviours seen in Bob’s OCD. OCD linked to abnormality/excessive activity in orbital frontal cortex/thalamus; abnormal functioning of parahippocampal gyrus – related to regulation of unpleasant emotions.
-Low levels of neurotransmitters, eg serotonin - serotonin might be removed too quickly before impulses have passed.
Genetic explanations – Bob’s family history is being looked at.
-Focus on search for gene markers Bob might have inherited – gene 9, COMT, SERT.
-Family studies indicate higher % of first degree relatives, ie parents, have disorder –10% compared to prevalence rate of 2%.

43
Q

A

A01 basic assumptions of behaviourist approach
-theory of classical conditioning
-Pavlov’s research
-theory of operant conditioning
-Skinner’s research.
A03
-focus on environmental causes & experience vs focus on internal influences (nature vs nurture). Discussion of interactionist approach
-approaches to treatment (eg flooding vs drug therapy)
-use of scientific methods
-issue of determinism
- issue of reductionism
-use of animal experiments & extrapolation
-contrasting implications (eg blame responsibility & social stigma).

44
Q

Outline research into the effect of situational variables on obedience and discuss
what this tells us about why people obey.
AO1 = 6 and AO3 = 6 12 marks

A

A01 Proximity - Milgram - teacher & learner were in same room, obedience decreased; touch proximity condition; experimenter leaves room, obedience decreased
-Location Milgram run-down office block vs Yale; Hofling hospital location
-Uniform - Bickman – more likely to obey man dressed as guard. Milgram’s experiment
experimenter wore grey lab coat
A03 Analysis of effects of variations
-Discussion of reasons why rate of obedience changes (agentic/autonomous state; legitimacy of authority; personality/dispositional factors)
-Methodological evaluation of research when used to analyse variables eg demand
characteristics, external validity may be more a feature of some variations than others
-Use of systematic procedures to ensure cause & effect could be established. enables
conclusions to be drawn
-evidence/real-life examples to support or contradict research into effect of variables eg
Mandel (1998) – mass killing of Jews was undertaken in close proximity of victims without protest; Slater’s (2006) study in virtual environment included condition where participant had to shock learner via text from a mobile phone.

45
Q

Using your knowledge of research into the effects of anxiety on eye-witness testimony, explain why Zina’s and Amanda’s statements are different.
4 marks

A
  • When anxiety/arousal is high, as is case for Zina leads to decrease in accuracy/detail compared with Amanda. supported by research, e.g. Johnson & Scott found those in high anxiety condition less likely to accurately identify man; Duffenbacher meta-analysis found high levels of anxiety negatively affected memory of eyewitnesses
  • When anxiety/arousal is high, as is case for Zina, leads to increased accuracy/detail compared with Amanda. supported by research evidence, e.g. Christianson & Hubinette where victims were more accurate than onlookers; Yuille & Cutshall’s study where those witnesses that were close to shooting were accurate, even months later.
46
Q

Describe and evaluate interference as an explanation for forgetting.
AO1 = 6 and AO3 = 6 12 marks

A

A01- Interference where two lots of info become confused in memory
-Proactive interference=where old learning affects recall of new info
-Retroactive interference=where new learning affects recall of old info
-Newer info may overwrite earlier info
-Interference more likely to occur when two pieces of info are similar
- impact of passage of intervening events on forgetting
A03 -research evidence support or contradict role of interference
-Loss of info may only be temporary, therefore interference isn’t true explanation for
forgetting
-Issue of validity - evidence interference can explain forgetting frequently comes from artificial lab experiments using artificial tasks, so interference may not occur to same extent in more real-life settings & scenarios, so challenging interference as explanation of forgetting
-However, everyday/real life situations have shown interference can explain forgetting, eg Baddeley and Hitch Schmidt et al (2000)
-Practical applications, e.g. revision strategies
-Alternative explanations can be used to critique.

47
Q

Outline and evaluate the learning theory of attachment

AO1 = 4 and AO3 = 4. 8 marks

A

A01 Idea of ‘cupboard love’ children learn to become attached to caregiver because they give them food
-Secondary drive/drive reduction in relation to feeding & attachment
-Learning can be due to associations (classical conditioning) – outline how process works in
attachment
-Learning can be due to patterns of reinforcement (operant conditioning) – outline of how process works in attachment
-Dolland & Miller (1950) - Infants learn to associate caregiver with feeling of pleasure when they are fed (classical conditioning) & infants reinforced in behaviours that will produce these desirable responses from others (e.g. being fed when they cry - operant conditioning).
A03 Evidence that underpins theory
-Evidence to refute theory: e.g. Schaffer & Emerson – more than half of infants were not
attached to person primarily involved in their physical care; Harlow – rhesus monkeys attach for comfort not food
-Other factors may act as reinforcers and not food – attentiveness & responsiveness (Ainsworth)
• Comparison with alternative explanations, e.g. Bowlby.

48
Q

Briefly outline one problem associated with alpha bias in psychological research, and one problem associated with beta bias in psychological research.
4 marks

A
  • alpha bias there is a misrepresentation of behaviour researchers exaggerate gender differences.
  • beta bias there is a misrepresentation of behaviour because researchers minimise gender differences.
49
Q

Briefly outline what psychologists mean by ‘levels of explanation’.
2 marks

A

-There are different levels of explanation and the behaviour can be explained at different levels (e.g. social and cultural, psychological or biological).

50
Q

Explain how the researcher might develop the above investigation through taking a nomothetic approach.
6 marks

A
  • Taking a nomothetic approach involve researcher testing larger sample of offenders.
  • Sampling should involve method of sample selection to give representativeness of larger population, eg random sampling of prison population.
  • researcher probably use testable hypothesis, eg violent offenders have more negative thoughts about childhood than non-violent offenders.
  • Taking nomothetic approach involve collection of a large amount of data.
  • Analysis probably involve quantitative methods, eg statistical testing & drawing of conclusions in relation to a wider population.
51
Q

Briefly outline how excitation and inhibition are involved in synaptic transmission. 4 marks

A
  • Neurotransmitters can be excitatory or inhibitory (most can be both but GABA purely inhibitory).
  • If neurotransmitter is excitatory then post synaptic neuron more likely to fire an impulse.
  • If neurotransmitter is inhibitory then the post synaptic neuron is less likely to fire an impulse. -excitatory & inhibitory influences are summed, if the net effect on post synaptic neuron is inhibitory, neuron less likely to ‘fire’ & if net effect is excitatory,neuron be more likely to fire.
52
Q

Outline two features of the cognitive approach. Explain two limitations of the cognitive approach. 8 marks

A

A01- Behaviour influenced by thoughts can be both conscious & non-conscious –internal mental processes.
-Schema-mental representation of experience & knowledge & understanding.
-Mental processes info processing & processing can be compared a computer.
-Models used to provide testable theories about mental processing & these can be
studied scientifically & inferences made.
-Cognition & biological processes can be integrated leading to cognitive neuroscience as a way forward to understanding human behaviour.
-Methodology -controlled experimentation – inference about mental processes on basis of observed behaviour.
A03- approach seen as mechanical in regarding human thinking as processing like computer leaving little room for irrationality seen in emotional behaviours.
-focus on detail of exactly what can be recalled by participants in controlled environments means an understanding of everyday use of memory, eg is missing from explanations.leads to issues of generalisation.
-process of inference may be a ‘leap too far’ in explaining thinking.
-soft determinism & little room for processes other than internal mental events affecting behaviour like biology.
-Research findings indicate factors other than internal mental events as cause of behaviour.
-self-report as method of data collection & issues of reliability.
-focus on individual mental processes like attention,little room for how these mental events work together.

53
Q

Outline and evaluate neural and genetic explanations for obsessive-compulsive disorder. Refer to the conversation above in your answer.
AO1 = 6, AO2 = 2 and AO3 = 4
12 marks

A

A01- Neural explanations include
-Low levels of neurotransmitters eg serotonin. Serotonin may be removed too quickly before it has transmitted its signal.
-basal ganglia system been implicated-communication within these areas is disturbed & might account for repetitive behaviours seen in OCD.
Genetic explanations include-Specific gene markers eg gene 9, COMT gene, SERT gene.
-Looking for gene markers that might have been inherited – like gene 9.
-Family studies indicate higher percentage of first degree relatives have this disorder,
10% compared to prevalence rate of 2%.
A02-Melanie suggests David might have inherited OCD because his mother displays similar behaviours & may have passed on genetic marker to him as first degree relative – genetic cause.
-Emma suggests David could have OCD due to biological factor in his brain –neural cause.
A03-findings from neural explanations problematic as drugs used to affect serotonin like SSRIs may decrease symptom but doesnt mean an imbalance of serotonin was cause in first place.
-Improvement rates from use of drugs only at 50% so must be other causes.
-There is time delay in which drugs affect levels of serotonin within hours/ immediately but the effect on OCD may take up to weeks.
-Some research into brain structure suggested involvement of structural abnormalities like dysfunction in lower grey matter density in people with OCD.
-Neurophysiological factors aren’t consistent with specific areas in brain being implicated.
-Sometimes evidence relates only to one aspect of disorder –compulsions rather than obsessions.
-Findings from family studies could be explained by shared environments as well as shared genes by SLT.

54
Q

Discuss two explanations of resistance to social influence. As part of your discussion, refer to the views expressed by Jack and Sarah in the conversation “Two psychology students were discussing the topic of social influence.
‘I find it fascinating how some people are able to resist social influence’, said Jack. ‘It must be the result of having a confident personality.’
‘I disagree’, replied Sarah. ‘I think resisting social influence depends much more on the presence of others.
AO1 = 6, AO2 = 4 and AO3 = 6 16 marks

A

A01-loc-people with internal loc more likely to resist pressure to conform & less likely to obey than those with an external loc people with internal loc believe they control own circumstances; less concerned with social approval. Credit measurement of loc Rotter
-social support – defiance/non-conformity more likely if others are seen to resist influence; seeing others disobey/not conform gives observer confidence to do so; forms of social support – disobedient role models (obedience), having ally (conformity); explanation of why these produce resistance, eg breaks unanimity of group in conformity situations, challenges legitimacy of authority figure.
A02- Jack suggests dispositional factors in resisting social influence more important
-Sarah indicates situational factors more powerful
-strong personality’ could be read as having internal loc makes someone better able to resist social influence
-what other people are doing at the time’ relates to whether ‘they’ seen to be
conforming/obeying, suggesting social support is influential in resisting social influence.
A03-commentary on two explanations of resistance to social influence
-evidence to support influence of explanations chosen, eg specific studies of defiance/non-conformity and/or variations of Aschs and/or Milgrams basic experiments demonstrated increased resistance
-real-world examples to illustrate explanations
-other social psychological concepts used to support discussion of explanations, eg influence of social support may be explained by reduced normative pressure, minority influence
-comparison/analysis of relative power of explanations
-discussion/analysis of different forms of resistance, eg independent behaviour vs anti-conformity.

-central executive & slave systems– visuo-spatial scratch/sketch pad;
phonological store/loop; articulatory loop/control process; primary acoustic store; episodic buffer
-info capacity & coding of each store
-allocation of resources/divided attention/dual-task performance.
A03-strengths include: explains how cognitive processes interact; memory is active rather than passive; provides explanation/treatments for processing deficits; highlights different memory tasks STM can deal with by identifying separate components; explains results of dual task studies
-limitations include: vague, untestable nature of ce; supported by highly controlled lab studies may undermine validity of model
-evidence to support or refute model

56
Q

Briefly evaluate learning theory as an explanation of attachment.
4 marks

A

A03-strengths: plausible & scientific as founded in established theory, ie likely that association between provision of needs & person providing those needs can lead to strong attachments; reinforcers clearly delineated

  • limitations: reductionist-focus on basic processes (S-R links, reinforcement) too simplistic to explain complex attachment behaviours; environmentally deterministic such that early learning determines later attachment behaviours; theory founded in animal research & problems of inferring on basis of animal studies
  • evidence used support or refute explanation: Schaffer & Emerson –more than half of infants weren’t attached to person primarily involved in their physical care; Harlow – rhesus monkeys attach for contact comfort rather than food; sensitive responsiveness may be more influential in forming attachments (Ainsworth); infants are active seekers of stimulation, not passive responders (Schaffer)
  • comparison with alternative explanations, eg Bowlby’s theory.
57
Q

58
Q

The investigation in question 09 is an example of a ‘naturalistic observation’.
Briefly discuss how observational research might be improved by conducting
observations in a controlled environment.
4 marks

A

A03-controlled environment affords opportunity for control of extraneous variables
-examples of extraneous variables that might be controlled and how/why they could affect
outcome of a study if not controlled
-exclusion of extraneous variables allows for greater inference about cause & effect
-exclusion of extraneous variables means researcher can replicate the observation to
check for reliability of the effect.

59
Q

Discuss research into the influence of early attachment on adult relationships.
AO1 = 4 and AO3 = 4
8 marks

A

A01-Bowlby’s internal working model –early attachment provides blueprint for later (adult) attachment; formation of mental representation/schema of first attachment relationship; affects later relationships & own success as parent
-adult attachment interview (Main et al) continuity between early attachment type & adult classification–procedure & coding system (insecure-dismissing, autonomous-secure, insecure-preoccupied, unresolved)
-studies support or refute relationship, eg Hazan & Schaffer; Quinton; Harlow; Freud and Dann; Koluchova.
A03-discussion of theory, eg Bowlby’s IWM & issue of determinism; negative implications of assumption relationship is cause & effect
-discussion of underpinning evidence re measuring adult attachment type and/or methodological evaluation of studies demonstrate a relationship & how this affects conclusions to be drawn, eg difficulty of establishing cause & effect between early attachment history and adult relationships
-counter-evidence, eg to suggest children can recover from deprivation/privation & form effective adult relationships
-ethical issues, eg associated with use of adult attachment interview
-evidence to support or refute relationship.

61
Q

Discuss the contribution of behaviourist psychologists such as Pavlov and Skinner to
our understanding of human behaviour.
AO1 = 6 and AO3 = 10
16 marks

A

A01-gave appreciation of how behaviour is learnt & environmentally determined
-large scale data gathering & generalisation allowed for development of laws & principles
-theories of learning & laws of learning – classical & operant conditioning theories
-emphasised importance of consequences, ie behaviour thats rewarded likely to be repeated
-emphasised role of reinforcement & punishment –strengthens or weakens learning
-insistence on objectivity & study of overt behaviour –raising psychology’s scientific status.
A03-strict scientific methods, objectivity, controlled research, verifiable findings led to raised status of psychology meant many aspects of human behaviour couldn’t be studied
-implications, eg development of laws & principles enabled prediction & control of behaviour & how these apply to human behaviour
-usefulness for aspects of human behaviour, eg therapy, classroom management etc
-reductionist approach focusing on lower level of explanation, eg S-R links/associations
therefore lacks meaning when it comes to complex human behaviours
-focus just on behaviour neglected whole person, eg in treatment using conditioning only
-strongly deterministic – human behaviour is environmentally determined – what of free will?
-research mainly with animals therefore generalisation to human behaviour could be limited
-discussion about balance between reliability & validity in behaviourist research
-ethical issues, eg as applied to control of human behaviour
-comparison with what other approaches offer in explanations of human behaviour.

Q

Briefly evaluate research using split brain patients to investigate hemispheric
lateralisation of function.
AO3 = 4
4 marks

A

A03-disconnection between hemispheres was greater in some patients than others
-some patients had experienced drug therapy for much longer than others
-comparison groups werent considered to be valid as they were often people with no
history of epileptic seizures
-data were artificially produced as in real life a severed corpus callosum can be compensated for by unrestricted use of two eyes
-research has added to unity of consciousness debate
-research relates to small sample sizes.

65
Q

Briefly explain one reason why it is important for research to undergo a peer review process.
2 marks

A

-prevents dissemination of irrelevant findings/unwarranted claims/unacceptable interpretations/personal views and deliberate fraud – improves quality of research
• ensures published research is taken seriously because it has been independently scrutinised
• increases probability of weaknesses/errors being identified – authors and researchers are
less objective about their own work.

A01-Misleading info including leading questions:
-Loftus & Palmer’s experiment where verb in critical question changed
(smashed, collided, bumped, hit or contacted
-Loftus & Palmer: “Did you see any broken glass?”
-Loftus et al study using red Datsun & Stop or Yield signs.
-Research relating to age also relevant eg Warren et al found adults less likely to be influenced by leading questions than children
-research eg post-event contamination; confabulation; reconstructive memory formation of schemas;confabulation.
Anxiety:
-Loftus’s weapon focus experiment found more participants correctly identified person holding pen 49% than person holding knife covered in blood.
-Loftus Burns found participants who saw violent version of crime where boy was shot in face had impaired recall for events leading up to accident.
-Peters found participants who visited healthcare centre better able to
recognise researcher than nurse who gave an injection. Yuille & Cutshall found witnesses who had been most distressed at time of shooting gave most accurate account 5mths later.
-Christianson & Hubinette found victims of genuine bank robberies more accurate in recall than bystanders.
-research/theory: eg Yerkes-Dodson law of arousal.
Post-event discussion:
-Source monitoring theory; effects of conformity; Bodner et al (2009) – effects of
post-event discussion can be reduced if witnesses are warned of its effects.
AO2
-Links to leading questions – ‘Did you see the knife?’ (as opposed to a knife); question from officer is leading witness who wasn’t sure there was knife in first place.
-Links to anxiety – witness claims she was ‘so scared’ when incident took place; may inhibit or enhance memory depending upon how severe fear was.
-Links to post-event discussion – ‘my friends and I have talked about what happened so many times since that I’m almost not sure what I did see’.
AO3
-validity in lab studies or lack of control in real-life situations
-Methodological issues, sampling, replication & corroboration with other studies
-Ethical issues

A

A03

  • Problem of context affecting behaviour –research should take place in natural setting eg child’s home to increase validity
  • Most research observational so bias in observer interpretation – may be countered by using more than one observer
  • Practical issues eg need for fewer but shorter observation periods because of limited waking periods
  • Taking extra care in relation to ethics so not to affect child/parent in any way eg protection from harm, confidentiality etc.

Q

Discuss the effects of institutionalisation. Refer to the studies of Romanian orphans in your answer.
16 marks

A

A01 Likely effects include: effects identified by Bowlby eg low IQ affectionless psychopathy, delinquency,
-Effects identified in privation studies: eg Harlow’s findings of delinquency, affectionless behaviour
-ERA findings of quasi-autistic symptoms in Romanian orphans, impaired language & social skills; disinhibited attachment; attention seeking, clinginess; lower frequency of pretend play and reduced empathy Kreppner et al more likely to be classified as disorganised attachment type Zeanah et al
-effects of levels of privation in institutions (Gunnar 2000)
-links to theory-lack of internal working model.
A03
-Research enhanced understanding of negative effects – establishment of key workers in institutions
-Evidence that adverse effects of institutionalisation can be overcome with adequate substitute care: eg Rutter,Hodges and Tizard
-Importance of age of adoption & quality/stability of aftercare
-Problems of generalising from Romanian studies as standards of care poor
-Adoption vs control groups werent randomly assigned in ERA studies –more sociable
children may have been selected
-Other studies, eg Bucharest Early Intervention Project, did randomly allocate but ethical issues with this
-Longterm effects on Romanian orphans arent yet clear
-Early studies of institutionalisation poorly controlled/effects extrapolated from animal studies

4 marks

A

A01

  • Adrenaline is released from adrenal medulla in response to activation of sympathomedullary pathway.
  • Adrenaline has range of effects on body
  • Direct effects of adrenaline:increase heart rate,constricts blood vessels, increasing rate of blood flow & raising blood pressure,diverts blood away from skin, kidneys & digestive system,increases blood to brain and skeletal muscle,increases respiration and sweating -general effects of adrenaline:prepare body for action, fight or flight, increase blood supply/oxygen, to skeletal muscle for physical action,increase oxygen to brain for rapid response planning

Q

Discuss how knowledge of hemispheric lateralisation and language centres in the brain has helped our understanding of cases such as Robert’s. Refer to Robert’s case in your answer. 16 marks
AO1 = 6, AO2 = 4 and AO3 = 6

A

A01
-Systematic research from Wernicke & Broca onwards has demonstrated in most people language centres are lateralised to the left hemisphere
-Wernicke’s area seems to be responsible for the interpretation of speech –damage leads to receptive or sensory aphasia
-Broca’s area thought to be responsible for production of speech now thought to involve wider network than just Broca’s area –damage leads to production (expressive) or motor aphasia
A02
-presence of right sided paralysis confirms in cases like Robert’s there’s lateralised damage to left hemisphere
-Robert, can understand speech so we conclude he doesn’t have Wernicke’s, receptive, aphasia; caused by damage to Wernicke’s area in left hemisphere.
-Robert can’t produce speech so we conclude
Broca’s area damaged leading to Broca’s, production or expressive aphasia.
A03
-As language centres are lateralised they can be impaired by damage to left hemisphere, not to right. left hemisphere also controls muscles of right side of body so, when brain damage leads to speech problems combined with paralysis of body muscles,usually right sided paralysis
-Damage to Broca’s area can lead to production/expressive aphasia combined with right sided paralysis
-Damage to Broca’s & Wernicke’s areas may lead to global aphasia (inability to understand or produce speech), combined with right sided paralysis
-research evidence to support explanation
-Problems associated with different types of research evidence

Q

Distinguish between a Type I error and a Type II error.

4 marks

A

A01

  • Type I error occurs when researcher claims support for research hypothesis with significant result when results caused by random variables
  • Type II error occurs when effect researcher was attempting to demonstrate does exist but researcher claims no significance in results accepts null hypothesis
  • difference is in Type I error null hypothesis is rejected when true & in Type II error its retained when its false.
78
Q

Briefly explain one reason why it is important for research to be replicated.
2 marks

A

A01

  • likelihood of same differences occurring twice (or more), by chance alone are much smaller than when they occur first time.
  • Effects that occur in study more likely to be reliable if they occur in repeat of study – replication therefore increases (external) reliability.

-ego: Rational, balancing id & superego (reality principle) formed between 18mo-3yrs, conscious part of mind
-superego: (morality principle) acts as conscience or moral guide, based on parental & societal values, formed between 3-6yrs, unconscious part of mind
-dynamic nature of three components
-experience/conflicts in childhood shape development of 3 parts affecting how person behaves
-levels of consciousness

Q

Explain the process of synaptic transmission

4 marks

A

A01

  • electrical impulses (action potentials) reach presynaptic terminal
  • electrical impulses (action potentials) trigger release of neurotransmitters
  • neurotransmitters cross synapse from vesicles
  • neurotransmitters combine with receptors on postsynaptic membrane
  • stimulation of postsynaptic receptors by neurotransmitters result in either excitation or inhibition of postsynaptic membrane.

A

A01
-fMRI –Uses magnetic field & radio waves to monitor blood flow; measures change in energy released by haemoglobin, reflecting activity of brain (oxygen consumption) to give moving picture of brain; activity in regions of interest can be compared during base line task and during specific activity
-EEGs – electrodes put on scalp & detect neuronal activity directly below where they are placed; differing numbers of electrodes can be used depending on focus of research
-ERPs – electrodes are put on scalp & detect neuronal activity (directly below where they are placed) in response to stimulus introduced by researcher
-post-mortem examinations –brain is examined after death to try & correlate structural abnormalities/damage to behaviour.
A03
-fMRI captures dynamic brain activity as opposed to post-mortem examinations which purely show physiology
-interpretation of fMRI is complex & is affected by temporal resolution, biased interpretation & by baseline task used
-fMRI research expensive leading to reduced sample sizes which negatively impact validity of research
-EEGs and ERPs cheaper so can be more widely used in research
-EEGs and ERPs poor spatial resolution
-post-mortem examinations may lack validity due to small sample sizes (special permission needs to be granted) & due to neuronal changes during & after death
-advantages of investigating brain activity in humans rather than generalising from animal
lesion/single electrode recording studies (validity and ethical reasons)
-comparisons between techniques is effective source of evaluation marks

Q

Describe the process and purposes of peer review.

6 marks

A

A01 process
-other psychologists check research report before deciding whether it could be published
-independent scrutiny by other psychologists working in similar field
-work considered in terms of validity, significance & originality
-assessment of appropriateness of methods & designs used
-reviewer can accept manuscript as it is, accept with revisions, suggest author makes revisions & re-submits or reject without possibility of re-submission
-editor makes final decision whether to accept or reject research report based on reviewers’ comments/recommendations
-research proposals submitted to panel & assessed for merit.
Purposes
-ensure quality & relevance of research, eg methodology, data analysis etc
-ensure accuracy of findings
-evaluate proposed designs (in terms of aims, quality and value of the research) for
research funding.
