Q

diagnosis and classification of schizophrenia

A

serious mental disorder affecting 1% population, more common in males, city-dwellers and lower socioeconomic groups
classification: identify symptoms that go together = a disorder
e.g. DSM-5 one positive symptom must be present, ICD-10 two or more negative symptoms are sufficient for a diagnosis
ICD-10 recognises a range of subtypes of schizophrenia, paranoid/catatonic, whereas current DSM doesn’t, ICD - globally by world health organisation, DSM - primarily used by american psychiatric association
diagnosis: identify symptoms and use classification system to identify the disorder

Q

symptoms of schizophrenia

A

positive symptoms: anything that’s been added to normal behaviour that wasn’t previously there
hallucinations, when you perceive something that isn’t actually there, most common types are auditory but also relate to all senses, unusual sensory experiences e.g. hearing voices
delusions, bizarre irrational beliefs that are clearly untrue e.g. believing to be being a victim of conspiracy
negative symptoms: the absence of normal behaviour
speech poverty, issues with normal communication, dsm recognises as positive, icd neg
avolition, absence of goal directed behaviour, poor motivation to do everyday tasks
catatonia, strange bizarre movements or holds the same position for hours on end
affective flattening, an absence of emotion

Q

not done genetic explanation for schizophrenia (biological)

A

family studies: strong relationship between degree of genetic similarity and shared risk of schizophrenia, gottesman found almost 50% chance of developing schizophrenia when identical twin with schizophrenia, almost 10% with siblings
candidate genes: schizophrenia is polygenetic, requires several genes, 108 separate genes associated with slightly increased risk of schizophrenia
mutation:

Q

*neural correlates of schizophrenia (biological)

A

dopamine hypothesis: originally linked to high levels of dopamine or too many d2 receptors on receiving neurons, d2 receptors effect attention and perception, so firing more likely increases risk of distorted perception like hallucinations, now linked to low levels too
neural correlates: links characteristics or experiences of schizophrenia to specific functions or activities in brain areas
amygdela is smaller in schizophrenics, responsible for basic feelings of fear, lust and anger, smaller means it links to flattening
visual and auditory cortex, same activity in these areas during hallucinations as genuine visual and auditory experiences
- biologically reductionist

Q

*cognitive explanations for schizophrenia (psychological explanations for schizophrenia)

A

dysfunctional thought processing: lower levels of information processing in some areas of the brain suggest cognition is impaired, e.g. reduced processing in ventricle striatum is associated with negative symptoms
metarepresentation: the cognitive ability to reflect on thoughts and behaviour, dysfunction disrupts our ability to recognise our thoughts as our own, leading to hallucinations or delusions
central control: cognitive ability to suppress automatic responses while performing deliberate actions, dysfunction leads to speak poverty as words trigger automatic associations that cannot be suppressed
- could be a symptom rather than a cause, schizophrenia may have caused disturbed thinking, issues with causality
+ support from stirling et al, compared performance in cognitive tasks, those with schizophrenia found it harder to name the front colours due to cognitive impairment

Q

typical antipsychotics (biological therapy for schizophrenia)

A

e.g. chlorpromazine
work by acting as antagonists in the dopamine system and aim to reduce dopamine action, strongly associated with dopamine hypotheses
they block the dopamine d2 receptors in the synapses in the brains that are linked to perception, which reduces dopamine action, initially increases levels but then production is reduced, normalises neurotransmission, reducing symptoms like hallucinations
also has a sedative effect, effects histamine receptors, can be used to calm anxious patients when first admitted to hospital
can be administered through tablets, injections or syrups
+ support for effectiveness, thornley, 13 trials over 1100 patients, drug was better than placebo in reducing symptoms and their severity
- side effects, sleepiness, agitation, weight gain, most serious is neuroleptic malignant syndrome (NMS) when dopamine is blocked in the hypothalamus and can lead to comas or death, can do harm as well as good, patients might avoid taking them

Q

atypical antipsychotics (biological therapy for schizophrenia)

A

e.g. clozapine
aim of developing newer drugs was to maintain/improve effectiveness of drugs in suppressing psychosis symptoms and minimise side effects of the drug used
binds to dopamine, serotonin and glutamate receptors
reduces depression and anxiety as well as improving cognitive functioning, improves mood, reducing schizophrenic suicide rates
e.g. risperidone
developed due to deaths related to clozapine
binds more strongly to dopamine receptors, therefore more effective in smaller doses than most antipsychotics and has fewer side effects, safer
+ have a lower rate of tardive dyskinesia, involuntary movements of the hands, lips, face and feet making patients more likely to take them
+ more effective in treating negative symptoms than typical antipsychotics

Q

*cbt (psychological therapy for schizophrenia)

A

aims to identify and challenge irrational thoughts e.g. delusions and hallucinations
coping strategy enhancement, specific cbt for psychotic symptoms of schizophrenia, based on tarrier research where triggers could be identified ad coping strategies were given e.g. distraction, positive self talk, behavioural strategies, relaxation training
5-20 sessions that can be done individually or in a group
helps patients to understand how their delusions and hallucinations impact their feelings and behaviours, e.g. hearing voices - demons - afraid
normalisation involves explaining to the patient that hearing voices is an ordinary experience
example: turkington et al treated a paranoid client who believed the mafia was trying to kill him, acknowledged the anxiety, explained other, less frightening possibilities and gently challenged his beliefs
- not accessible for everyone, learning disabilities or unable to communicate
+ supporting research, tarrier found reduction in positive symptoms with cbt in comparison to control group

Q

*family therapy (psychological therapy for schizophrenia)

A

aims to reduce levels of expressed emotions, especially negative emotions like anger and guilt that create stress, reducing these reduces the chance of relapse
therapist encourages family members to for a therapeutic alliance, all agree on aims of the therapy, also tries to improve their beliefs and behaviours towards schizophrenia, achieve a balance between caring for the individual with schizophrenia and maintaining their own lives
burbachs model: phase 1 and 2, share information, identify resources family can offer, phase 3 and 4, learn mutual understanding, look at unhelpful patterns of interaction, phase 5, 6 and 7, skill training (e.g. stress management techniques), relapse prevention and maintenance
+ benefits not just the individual, helps the family know how to give support, wider benefits to society and to the individual
+ supporting evidence, mcfarlane found relapse rates reduced by around 50-60%
- doesn’t address underlying cause just prevents relapse

Q

*token economies (management of schizophrenia)

A

ayllon and azrin used a token economy in a schizophrenia ward, a gift token was given for every tidying act, which could then be exchanged for privileges e.g. films
institutionalisation occurs in long term hospital treatments, matson et al identified three categories of institutional behaviour that can be tackled using token economics: personal care, condition related behaviours and social behaviour, modification to this behaviour doesn’t cure schizophrenia but has two benefits
1. quality of life, improve quality of life in the hospital setting
2. ‘normalises’ behaviours, encourages return to ‘normal’ behaviour, making it easier to adapt once out of the hospital
process: tokens given immediately after desired behaviour, target behaviour decided individually, then sapped for rewards, must be given tokens immediately or its less effective
based on operant conditioning, tokens are secondary reinforcers exchanged for primary reinforcers (rewards), generalised reinforcers, tokens that can be exchanged for a range of different primary reinforcers are more effective
- ethical issues, professionals have the power to control people’s behaviour, may make them more distressed by not having pleasures
- not long term, behaviours are likely to return once out of hospital
+ easy to implement, doesn’t require specialists, cheap

Q

*interactionist approach to schizophrenia

A

considers combined effects of biological, psychological and social factors on the development and treatment of schizophrenia
(original) diathesis stress model: diathesis, genetic vulnerability (schizogene), if a person didn’t have this gene they wouldn’t develop schizophrenia, stress, environmental trigger (schizophrenic mother), triggers gene to develop schizophrenia
(new) diathesis stress model: original too simplistic, diathesis, any vulnerability, stress, any kind of trigger
+ tienari et al: investigated combination of genetic vulnerability and parenting style in children adopted from finnish mothers with schizophrenia, adoptive parents assessed on child-rearing style, compared with control of no genetic risk, high levels of criticism and conflict and low levels of empathy lead to development of schizophrenia in children with the genetic risk
+ holistic, integrates multiple factors, more reflective of the complexity
treatment involves combining antipsychotics with a psychological therapy (usually cbt), antipsychotic reduces dopamine activity and cbt helps identify negative thoughts
+ tarrier et al: randomly allocated patients to medication + cbt, medication + supportive counselling group or control group, just medication, patients in experimental groups showed less symptoms than control, approach is beneficial and reduces suffering
- challenging in practice, may find it hard to adhere to both treatments simultaneously, requires collaboration between healthcare professionals from different disciplines

Q

*reliability and validity in classification and diagnosis of schizophrenia

A

reliability: how consistent findings are, in context of schizophrenia, extent to which psychiatrists can agree on the same diagnosis when independently assessing patients (inter-rater reliability), should reach the same diagnosis each time
(ao3): rosenham ‘being sane in insane places’, pseudo patients did not all receive the same diagnosis when in psychiatric hospitals showing the same symptoms, hearing voices and feeling ‘empty’, poor consistency in diagnosis and classification, poor inter-rater reliability
validity: how accurate the results are, consider validity of diagnosis tools, do dsm and icd measure what they are supposed to?
(ao3): cheniaux et al, two psychiatrists independently diagnosed 100 patients using dsm and icd criteria, more likely to be diagnosed with icd than dsm, 68 icd and 39 dsm, lack of criterion validity
(two of) co-morbidity, symptom overlap, gender bias, cultural bias + ao3

Q

*piagets theory of cognitive development

A

children don’t know less, they just think differently, changes through stages, motivation plays an important role in learning and drives how learning takes place
schemas: mental representation of our knowledge of the world, infants born with a few but construct new ones from the start
disequilibrium: when a child cannot make sense of their world due to insufficient schema knowledge, uncomfortable state
equilibrium: pleasant state of balance achieved by exploration and learning, when experiences in the world match the state of our current schema
assimilation: incorporate new experience/information into an existing schema, e.g. new breed of dog fits into dog schema
accommodation: creation of a new schema or major change to an existing schema, e.g. making a new cat schema after thinking it was the same as a dog originally
- underestimated role of other people, contrast with vygotsky, limited explanation
+ revolutionised teaching, readiness, discovery learning, children activity engage in constructing their knowledge, positive impacts

Q

*vygotsky’s theory of cognitive development

A

develop reasoning skills through social processes
cultural differences in cognitive development as we grow up and learn about the world surrounded by our cultural values and beliefs
zone of proximal development: gap between what a child knows and can do alone, and the potential capabilities, following interaction with someone more expert, role of the teacher is to guide us through this gap
advanced reasoning ability: becoming more skilled at reasoning, most advanced reasoning can only be achieved through the help of experts, not just exploration
scaffolding: process of helping a learner across the ZPD and advance as much as possible, typically level of help decreases as the learner progresses across the ZPD, strategies include, demonstration, preparation for child, specific verbal instructions, general prompts and indication of materials
+ real world applications to things such as tutoring, children progressed further in reading than a control when they had tutors, real world value in education
- individual differences, not all children learn best in a social situation, have to consider personality of learner, not applicable to all children

Q

*piaget vs vygotsky

A

piaget: schemas, motivated to learn through disequilibrium, assimilate or accommodate, stage theory
vygotsky: sociocultural context of cognitive development, learn through social interactions with more knowledgeable others, language plays essential role, zpd and scaffolding helps child move through cognitive development
similarities (ao3): children play an active role, piaget - direct interactions with environment for schema adaptation, vygotsky - social interactions, both led to practical applications, piaget - readiness and discovery learning, vygotsky - scaffolding in teaching
differences (ao3): role of culture, piaget - universal stages, similar in all cultures, vygotsky - interactions can be different dependent on the social and cultural environment, when children learn best, piaget - readiness, only understand when cognitively ready, biological maturity, vygotsky - accelerated through social interactions with others

Q

baillargeon’s explanation of infant abilities

A

suggested children have a better understanding of the physical world than piaget proposed, and behaviour is better explained by poor motor skills or distractions
violation of expectation (VOE): technique to compare babies reactions to an expected and unexpected event to make inferences about an infant’s cognitive abilities
study: 24 babies, 5-6 months, shown tall or short rabbit passing behind a screen with a window, expected condition - could see the tall rabbit but not the short, unexpected - neither rabbit was seen, looked for and average of 33s in unexpected, 25s in expected, interpreted as they were surprised at the unexpected, showing object permanence before 6 months
physical reasoning system (PRS): enables us to learn about the world more easily, develops with experience, object persistence - we know objects do not disappear e.g. from birth babies can identify event categories (ways that objects interact), object persistence means they quickly learn that one object can block another (occlusion)
+ validity of VOE research, control of cofounding variable, distraction, more reasonable assumption than piaget saying the object didn’t exist to them
- credibility of physical reasoning, working with newborns makes it hard to distinguish what they are actually thinking or responding to
+ explains why physical understanding is universal, innate, know that if we drop something it will fall to the floor, no cultural differences found

19
Q

*selmans levels of perspective-taking (stages)

A

Eat Ur Shit Idiot Son Real Men Shave Carefully
selman disagreed with piaget, social perspective taking develops separately from other aspects of cognitive development
research: asking children to take the perspective and consider the emotions of different people in a social situation e.g. holly not climbing up trees but seeing a cat stuck up one, seeing how each person would feel if she climbed the tree
EU: egocentric or undifferentiated perspective, 3-6, unaware of any perspective other than own, cannot distinguish between own and others emotions
SI: social informational role taking, 6-8, recognise others have different perspectives because they’ve received information
SR: self reflective role taking, 8-10, know that viewpoints may conflict even when receiving the same information, cannot consider more than one at a time
M: mutual role taking, 10-12, can consider different viewpoints at the same time
SC: social and conventional role taking, 12+, understand another’s perspective by comparing it to the society in which they live
key elements: interpersonal understanding, interpersonal negotiation strategies (having to develop other skills), awareness of personal meaning of relationships (relating social behaviour to the people we’re interacting with)
- only one aspect of social development considered, empathy and external factors are also important, over simplified
+ helps to understand atypical development, children with adhd found the task more difficult, couldn’t identify feelings and consequences, key social deficit found, leading to interventions and specialised support

20
Q

*theory of mind

A

personal understanding (theory) or belief about what other people know, are feeling or thinking, looks at the age this develops
intentional reasoning tasks: test whether children understand and can explain the motives, beliefs and thoughts which cause others to perform certain actions
false beliefs tasks: whether children understand that people can believe something that isn’t true
meltzoff: 18 month old children observed adults placing beads into a jar, the experimental condition involved adults struggling with this and dropping some outside the jar (control - did it successfully), in both conditions toddlers placed the beads in the jar, imitating what the adult intended to do, showing a theory of mind
eyes task: older children with asd can succeed on false belief tasks, so baron-cohen developed a task that involved reading complex emotions from eyes, adults with asd struggled to identify the emotions, ToM is a possible cause of asd
sally-anne experiment
- false belief tasks have low validity, involve other processes like memory, studies with visual aids had greater success for children
- eyes task lacks mundane realism, looking at pictures doesn’t reflect real life
- children who fail false belief tasks can pretend play which involves a ToM, doesn’t measure what it’s supposed to so lacks validity

21
Q

*sally-anne study (theory of mind)

A

baron-cohen
20 children with autism, 14 with down syndrome, 27 without a diagnosis (control group) children were told a story involving two dolls, sally and anne, sally put a marble in her basket and left the room and children were asked where sally would look for the marble after anne moved it to her own box
results: 85% of children in the control group correctly said where sally would look for her marble because they had developed theory of mind as sally would not know the marble had been moved, in the asd group only 20% could identify this, which explains deficits in the theory of mind and how it could explain autism as they struggle to attribute false beliefs to others
- low validity of research tasks, may fail false belief tasks due to others cognitive abilities, such as forgetting parts of the story
- low consistency of results

22
Q

not done mirror neuron system

A

mirror neurons respond to motor activity of others

23
Q

not done *top-down approach to offender profiling

A

behavioural and analytical tool of scene and evidence to predict characteristics of unknown criminals, narrow down likely suspects list, used by professional profilers
usa, 1970s, fbi conducted interviews with 36 sexually motivated killers
pre-established typology, offenders have a signature ‘way of working’
organised: no evidence left, high iq, control and precision, have a ‘type’, usually married sometimes with kids, planned crime
disorganised: overkill, leave evidence or body, impulsive
the construction of an fbi profile has four stages: data assimilation, crime scene classification, crime reconstruction, profile generation
- issues with fbi research, self-report techniques, limited sample
- cannot be generalised to all crimes, burglary, assault
+ support for organised offenders, canter et al, 100 murder cases, 39 characteristics

24
Q

not done*bottom-up approach to offender profiling

A

work up from the crime scene evidence, build hypothesis about characteristics, routines and social backgrounds
investigative psychology: uk, statistical procedures and psychology theories, identify patterns of behaviour and create a statistical database for comparison
smallest space analysis: ‘closeness’ of various traits
interpersonal coherence, forensic awareness
geographical profiling: rossmo, spatial consistency, predict offenders base or future crimes, mark on map, examine spread, build jeopardy surface, predict next strike
circle theory: canter and larkin, marauders, commuters
+ scientific and objective
+ can be applied to more crimes
+ evidence for geographical, canter et al, 66 sexual assaults

25
not done*historical approach, activist form (biological explanation of offending behaviour)
‘genetic throwbacks’, incapable of conforming to modern society norms lombroso: shifted from moral approach to a more scientific, studied 4000 criminals, found that 40% of criminal acts had offenders with activist features they lack evolutionary development physical features: markers for criminals, strong jaw, facial asymmetries, narrow/sloping brows also included unemployment, criminal slang, insensitivity to pain - methodological issues, no control group, physiological conditions - issues of causation, ignores environmental factors, determinist + influential
26
not done*genetic explanation (biological explanation of offending behaviour)
twin and adoption studies suggest genes predispose offenders to crime, candidate genes: tiihonen et al, genetic analysis of about 800 offenders, found two genes that may be associated with violent crime, MAOA gene regulates serotonin and is linked to aggressive behaviour, CDH13 gene linked to substance abuse and adhd, 5-10% of severe violent crime in finland is attributable to these genotypes diathesis-stress model: a tendency to offending behaviour is due to a combination of genetic predisposition and a biological or psychological stressor or trigger e.g. criminal role models or dysfunctional upbringing - twin studies + support for diathesis-stress model
27
not done*eysenck’s theory/personality theory (psychological explanation of offending behaviour)
certain personality traits may lead to offending behaviour extroversion: underactive nervous system, risky behaviours, seek excitement neuroticism: unstable, jumpy psychotism: cold, prone to aggression, manipulative has a biological basis, personality is based on nervous system, emotional responses to events, innate/inherited crime by socialisation, consequences of actions, not socialised effectively scales/tests, esyencks personality questionnaire - oversimplified, digman suggested 5 factor model, openness, agreeableness and contentiousness - cultural differences, hispanic and african american, less introverted + support from eysenck and eysenck, 2000 prisoners, about 2400 controls, high e/n/p
28
not done*cognitive (psychological explanation of offending behaviour)
cognitive factors lead to offending behaviour, lower level of moral reasoning, mistakes in processing kohlbergs model of moral reasoning, stage theory, offenders lower stage, have moral dilemmas and analysed responses and background preconventional morality: conventional morality: post conventional morality: cognitive distortions hostile attribution bias: misinterpret ambiguous situations as hostile, roots in childhood minimisation: downplay or deny the significance of an event or emotion + applications to cbt - descriptive not explanatory, can’t explain why faults exist + support for moral reasoning, palmer/hollin, 126 offenders, dilemmas and questionnaires
29
not done*differential association (psychological explanation of offending behaviour)
social learning theory of crime, learn through association and interactions with important people in our lives learned attitude towards crime: exposed to more pro criminal attitudes, mathematically predict learning of specific criminal acts: techniques, explains why convicts go on to reoffend farrington: longitudinal study over 40 years, 400 males, recorded convictions and self reported crimes, 41% one crime, 7% chronic reoffenders childhood risk factors + sub cultural differences - difficult to scientifically test, one pro is said to outweigh five - individual differences, free will
30
not done psychodynamic (psychological explanation of offending behaviour)
roots of behaviour are formed in childhood blackburn: inadequate superego theory superego, phallic, oedipus/electra complex, moral principles weak superego: same sex parent absent, immoral behaviour deviant superego: internalise superego of our immoral/criminal behaviour over-harsh superego: strict parenting, guilt, unconscious, self punishment maternal deprivation theory, bowlby, warm continuous bond leads to strong adult emotional relationships, failure leads to affectionless psychopathy, delinquency - unfalsifiable + support from bowlby 44 thieves, 14 ap, 12 separation from mother - methodological issues, bias - contradictory points, avoid punishment, same sex parents still lead to crime
31
not done*custodial sentencing (dealing with offending behaviour)
aims of custodial sentencing: deterrence: putting people off committing crime incapacitation: protect the public by removing offenders retribution: revenge against the offender rehabilitation: reform the offenders psychological effects of custodial sentencing: stress and depression, suicide and self harm rates are higher in prison than in the general population, institutionalisation, inability to function outside of prison after adapting to prison life routines and norms, prisonisation, behaviours unacceptable outside prison are encouraged via socialisation into an ‘inmate code’ *recidivism: refers to reoffending, about 45% of uk offenders reoffend within a year - school for crime
32
not done behaviour modification (dealing with offending behaviour)
behaviourist approach, possible to unlearn undesirable behaviour behaviour modification programmes reinforce obedient behaviour whilst punishing disobedience token economy: based on operant conditioning, desirable inmate behaviours e.g. avoiding confrontation, following rules, are rewarded with tokens, but they may also be removed as punishment tokens are secondary reinforcers, tokens are not rewarding in themselves but because they can be exchanged for something desirable (primary reinforcers), e.g. a phone call to a loved one, extra food or cigarettes operationalised: target behaviours are operationalised by breaking them down into component parts (e.g. interactions with other prisoners - not touching others, speaking politely), each ‘unit’ of behaviour should be objective and measurable and agreed by staff and prisoners in advance scoring system: staff and prisoners should be aware if how much each behaviour is worth in tokens, behaviours are hierarchical, some more demanding than others, tokens may be awarded directly or points may be awarded and converted to tokens reinforcements should outweigh punishments by a ratio of 4:1 (gendreau et al) prison staff receive full training, aiming to standardise procedures so all staff reward the same behaviours, keep record if what tokens awarded so progress can be assessed + easy to implement, doesn’t need specialists, cost-effective, can be widely applied - little rehabilitative value, once not in institutions behaviour returns to original, anger management understands causes making it longer lasting - ethical issues, manipulative and dehumanising (moya et al), withdrawal of ‘privileges’ is unethical + support from hobbs and holt,
33
not done anger management (dealing with offending behaviour)
34
not done restorative justice (dealing with offending behaviour)
35
gender bias
universality: claim that observed behaviours apply to all humans, regardless of differences in gender, biology or culture, if a hypothesis isn’t tested on diverse sample, the assumption may not be generalisable bias: psychologists pre-existing beliefs and viewpoints influencing their theories and data interpretation, comes from personal experiences e.g. background, education gender bias: when stereotypical views about male and female behaviour affect researchers theoretical assumptions alpha bias: overemphasis or exaggeration of differences between males and females e.g. psychodynamic theory, freud assumed that girls identification with same-sex parent is weaker beta bias: ignoring or underestimating differences between men and women e.g. milgrams research, women were less likely to be obedient androcentrism: psychology tends to reflect male-centric view of the world, leading to female behaviour being misunderstood, due to most psychologists developing these theories being male - promotes sexism in the research - research challenging the bias may not be published
36
*cultural bias
cultural bias: interpreting and judging human behaviour based on cultural norms and experiences ethnocentrism: a form of cultural bias, superiority of own culture from researchers that’s used as a standard for evaluating other cultures e.g. strange situation, seems secure is most desirable, however japanese babies more likely to be classed as insecurely attached cultural relativism: the principle that behaviour should be understood in the context of the culture where it occurs, taking into account that cultures norms, values and beliefs, helps avoid cultural bias aschs study assumed results applied universally, however other research found other cultures didn’t conform as much some findings argued to be universal but our culture biased, weird, henrich, most likely participants in a study, westernised, educated people from industrialised, rich, democracies, it’s important to use diverse samples to reduce bias
37
not done free will and determinism
what influences our behaviours, most approaches are determist but disagree on the cause free will: able to make own choices, we can reject biological and environmental influences on our behaviour, e.g. humanistic approach hard determinism, all human actions have a cause, soft determinism, have a cause but people have freedom to make choices within a restricted range of options biological determinism environmental determinism psychic determinism science seeks causal explanations
38
*nature-nurture
looks at what behaviour is inherited or is based on experiences nature: nativists (e.g. descartes), human characteristics are innate, result of genes bowlby, innate baby behaviours, evolutionary, genetic, concordance for schizophrenia higher in identical twins nurture: empiricists (e.g. locke), mind is a blank slate at birth, shaped by interactions with the environment social learning theory, bandura, learn behaviour from environment, behaviourism, classical and operant conditioning measuring: concordance, the degree to which two people are similar to a participant interactionist approach: all characteristics are a combination of both, e.g. attachment, quality of parental love, bowlby and child’s temperament, kagan diathesis-stress model: behaviour caused by vulnerability and a trigger, e.g. schizophrenia epigenetics: change in genetic activity but not genetic code, lifestyle and events leave marks on our dna, switching genes on and off, lifelong influence + real world applications for both, nurture, challenging maladaptive thinking by using therapy, ocd, influenced by genes and environment - negative implications, natavists, determinist leading to implications for those of different cultures, genders, empiricists, changing behaviour through alternate environments, society may control and manipulate citizens, taking extreme positions, dangerous consequences so interactionist is preferred
39
not done*holism and reductionism
holism, looks at multiple factors affecting behaviour reductionism, reduces behaviour down to one explanation
40
*idiographic and nomothetic
debate over which position is preferable for psychology, a detailed study of one individual or group to provide in-depth understanding or study of larger groups with the aim of discovering norms, universal principles or laws of behaviour idiographic: number of participants is small, often a single person or group, initially understand the individual, then may be generalised based on findings, generally use qualitative research, roger’s counselling, based on in depth study of his clients from when he was a therapist nomothetic: general principles of behaviour are developed and then applied in individual situations, such as therapy, generally use quantitative research, seek to count human behaviour, data analysed for its statistical significance, skinner’s research, studied animals to discover general laws of learning objective vs subjective: nomothetic seeks standardised methods of assessing people, ensures true replication across samples of behaviour and removes the contamination of bias, idiographic tends not to believe objectivity is possible in psychological research, instead is people’s individual experience or their unique context that is important (subjective) + both approaches work together, idiographic qualitative data compliments nomothetic approach by providing more detail, hm looked at individual first and then researched memory to create general laws - idiographic on its own is ineffective, no baseline for comparison, it’s also subjective, difficult to build general effective theories without any nomothetic research
41
ethical implications of research studies and theory
ethical issues: arise because of conflict between the need for valid research findings and preserving the rights of participants, ethical guidelines, also relate to implications of research socially sensitive research (SSR): must be aware of consequences of the research for those being represented, may have consequences if not implications for the research procedures: consequences should be considered at all stages of the research process research question: phrasing of research question influences how findings are interpreted e.g. alternative relationships suggests homosexuality dealing with participants: informed consent, protection from harm, confidentiality, consideration of all these things how findings are used: have to be considered in advance, might give scientific credence to prejudices + potential benefits for groups studied with SSR, dsm removed homosexuality as a sociopathic personality disorder after research came out suggesting its normal, illustrates importance - however, negative consequences, e.g. criminal gene research may provide an excuse for bad behaviour, need for careful consideration of possible outcomes and consequences

co-morbidity: two or more conditions occurring together, schizophrenia commonly diagnosed with depression, 50%, buckley et al, common with other mental illnesses ao3 - two conditions together challenges validity of classification of both illnesses, could be due to not being able to tell the difference, misdiagnosis symptom overlap: considerable overlap between the symptoms of schizophrenia and other conditions, bipolar - positive symptoms like delusions, negative symptoms like avolition ao3 - may not be two different conditions but instead just one, misdiagnosis gender bias: longnecker found that more men get diagnosed with schizophrenia than women, females typically function better ao3 - women are less likely to be diagnosed as they appear to be coping better culture bias: african americans are more likely to be diagnosed then white people, hearing voices is more acceptable due different cultures ao3 - may not actually be a symptom, psychiatrists are usually white so are less likely to understand other cultures and more likely to misdiagnose and discrimination
