Q

Statistical infrequency

A

Abnormal behav (characteristics fall outside normal distribution) r rare + those behav found in few people. Mathematical method to define abnormality. Mathematical element is about the idea that human attributes fall in normal distribution in population. Central average/mean - rest of population fall above/below mean symmetrically. Standard deviation measures how far scores on either side from mean. M

Q

Deviation from Social Norms

A

Abnormality when behav doesn’t fit what’s socially acceptable. Dependant on culture behav occurs in. Social norms different in various cultures so abnormality different. How Deeply entrenched that norms is embedded in culture and how important culturally it is - important. slight deviation form norms may not be regarded as abnormal if norm isn’t considered important by society.

Q

Failure to function adequately

A

Abnormal behav is when an indiv not able to cope with everyday life. Acknowledges that people may act differently but if they have basic inability to manage in everyday life their behav is abnormal. Ability to function/cope defined by Rosenhan + Seligman in 7 sections. (E.g observer distress) GAF - global assessment of functioning scale- method to measure how well indiv function in everyday life and considers 7 sections + occupational functioning. An indiv must also be failing to function adequately before diagnosis is given

Q

Deviation from ideal mental health

A

Abnormality defined as deviating from ideal of positive mental health in terms of Jahoda’s (1958) criteria of ideal mental health. Absence form criteria indicates abnormality + potential mental disorder. J suggested 6 criteria need to be fulfilled for ideal mental health and if not, may experience difficulties (e.g accurate perception of reality)

Q

Statistical infrequency evaluation (real life application)

A

P - real life application in diagnosis of intellectual disability disorders
E - a place for statistical deviation in thinking about what r normal + abnormal behav and characteristics. All assessments of patients with mental disorders include some kind of measurement of how severe symptoms r compare to statistical norms.
E - SI is useful part of clinical assessment
I - shows real life application of SI and increase reliability + validity

Q

Statistical infrequency evaluation (subjective)

A

P - SI definition s that cut off points r subjectively determined
E - eg people disagree on what constitutes abnormal amount of sleep
C - but since it’s a symptom of depression, it’s important to know where cut off points lies for diagnosis to be made
E - disagreement about cut off points make it difficult to define abnormality in terms of SI

E - Where someone is living a happy fulfilled life, no benefit to them being labelled abnormal regardless of how unusual they r
E - eg someone with every low IQ may not be distressed + capable of working
I - shows labelling person as abnormal using def could have negative effect of their self view and way others view them

E - means a person from 1 cultural group may label someone from another cultural group as behaving abnormally according to their standards of person behaving in that way
E - eg hearing voices isn’t seen as abnormal in all cultures.
I - problematic to use social norms to define abnormal behav when diagnosing those from other cultures

Q

Failure to function evaluation (subjectivity accepting)

A

P - does attempt to include subjective experience of indiv
E - acknowledges that experience of patient + people around them is important.
E - In this sense failure to function adequately def captures experience of many of people who need help
I - suggests failure to function adequately is useful criticism for assessing abnormalities. Increases usefulness when diagnosing abnormality

Q

Failure to function evaluation
( professional diagnosis)

A

P - someone needs to decide whether this is actually the case
E - sometimes people experience personal distress + recognise their behav is undesirable
E - but sometimes people r content with their behav + it’s others who r distressed by it. whether behav is defined as abnormal or not depends on who is making judgment, may be subjective
I - means not all behav can be diagnosed objectively so decreases validity and reliability of def

Q

Failure to function evaluation
( functionality)

A

P - some apparently abnormal behav can be functional
E - eg depression may lead to extra attention for indiv. Attention is rewarding + therefore functional, even if generally regarded abnormal.
E - failure to function adequately is an incomplete def as fails to distinguish between behav that r dysfunctional + those that have some function for indiv
I - decreases validity of def due to its poor application to all abnormal behav

Q

Deviation from ideal mental health evaluation (very comprehensive)

A

P - very comprehensive
E - covers broad range of criteria for mental health. Some would argue it probably covers most of reasons people seek help from mental health services or referred for help. Sheer range of factors discussed in relation to Jahoda’s ideal mental health def make it good tool for thinking about mental health
C - unrealistic criteria
E - few people would satisfy all criteria all of time. Everyone would be described as abnormal to a degree so need Jahoda’s criteria need to narrowed down - Which specific absences would indicate abnormality

Q

Two process model

A

Mowrer introduced based on behavioural approach to phobias. States phobias learnt by classical conditioning + continue by operant. Whenever we avoid phobic stimuli, successfully escape fear and anxiety suffered if presence there. Reduction in fear is positive reinforcer and
reinforces avoidance behav and so phobia maintained

Q

Two process model evaluation (biological )

A

P - biological preparedness may be better explanation than model of how phobia work
E - eg it’s quite rare to develop a phobia of cars or guns as they’ve existed only recently so we’re not biologically prepared to learn fear responses to them.
E - seligman says animals r genetically prepared to learn associations between fear + stimulus that were life threatening in evolutionary past like snakes
I - Means behavioural explanations alone can’t explain phobia development

Q

Systematic desensitisation

A

Method using classical conditioning to gradually reduce anxiety around phobic stimulus. Aim to replace feelings of anxiety by the relaxation (counterconditioning ) impossible for indiv to be afraid and relaxed at same time. relaxation prevents experiencing fear (reciprocal inhibition)

Q

Flooding evaluation (cost effective/traumatising)

A

P - cost effective method of treatment
E - it’s comparable to other methods of treatments in terms of effectiveness as flooding is faster and efficient solution. Means patient could be treat faster and it could be cost effective for heath card provider
C - it’s traumatising for patients and creates high level of anxiety. Despite signing informed consent form, treatment could be more stressful than anticipated
E - result in patient leaving treatment incomplete, waste of money and time used

E - patients with phobias that aren’t developed thro personal experience - classic conditioning (eg fear of heights) not effectively treated using systematic desensitisation
E - some psychologists believe certain phobias like heights have evolutionary survival benefit and not result of personal experience but of evolution.
I - highlight limitation of systematic desensitisation, ineffective in treating evolutionary phobias

36
Q

Systematic desensitisation evaluation (diversity)

A

P - suitable for diverse range of patients
E - lots of individual who have anxiety disorders like phobias also have learning difficulties - make it very hard for some patients to understand what is happening during alternative to systematic desensitisation like flooding or engage with cognitive therapies that require ability to reflect on what u thinking
E - this increases it’s usefulness within the real world
I - appropriate treatment for many indiv

37
Q

Depression

A

Mental disorder characterised by low mood and energy levels

38
Q

Behavioural characteristics of depression

A

Activity levels - typically have reduced energy levels but oppose effects can occur ( psychomotor agitation- can’t relax)
Disruption to sleep + eating behaviour - might experience insomnia/hyper insomnia. Appetite increase/decrease
Aggression + self harm- irritable leading to aggression. Result in physical aggression directed against self

39
Q

Emotional characteristics of depression

A

Lowered Mood - describing themselves as worthless + empty
Anger
Lowered self esteem - emotional experience of how much we like ourselves

40
Q

Cognitive characteristics of depression

A

Poor concentration
dwelling on negative - ignore positive + focus on negative
Absolutist thinking (black/white thinking) - when situation is unfortunate they see disaster

41
Q

Becks cognitive theory of depression

A

Theory s way people think create vulnerability for depression. Beck s 3 parts to this cognitive vulnerability 

42
Q

Faulty information processing

A

When depressed people focus on negative aspects of situation + ignore positives . Tend to blow small problems out of proportion + think in black/white terms

43
Q

Negative schema

A

Use schemes to interpret the world so negative schemas + self schemas means info is interpreted negatively, including info about ourselves.
Negative schemas help maintain negative triad

44
Q

Negative triad

A

Beck proposed 3 types of automatic negative thinking contributing to becoming depressed (negative views of world, future + self)
Negative views lead interpretation of experiences negatively so more vulnerable to depression . Negative views about world create impression that there’s no hope anywhere as it reduces hopefulness for future + enhance depression, negative feelings about self enhance depressive feelings as confirm existing emotions of low self esteem

45
Q

Ellis’ ABC Model (1962)

A

Based on argument that good mental health is result of rational thinking - thinking allows people to be happy and pain free. Conditions like anxiety/depression r thought to be due to irrational thought - interfere with being happy + pain free
activating event (A) leads to irrational belief (B), consequences of this (C) may be depression
Musturbatory thinking is source of irrational beliefs. Like Utopiansism is belief life should be fair. People holding these beliefs may become depressed. For mental healthiness, these ‘musts’ need to be challenged

46
Q

Becks cognitive theory of depression evaluation(grazioli + terry, 2000)

A

P - supporting evidence for idea depression associated with faulty information processing, negative schemes + triad
E - grazioli + terry (2000) assessed 65 pregnant women for cognitive vulnerability + depression before + after birth. Found those women judged to have been high in cognitive vulnerability more likely to suffer post natal depression.
E - shows that CBT is almost effective treatment for depression
I - support cognitive explanation depression due to mental processing and increases validity due to evidence and application

47
Q

Becks cognitive theory of depression evaluation (useful application)

A

P - useful application for treating depression
E - eg becks explanation has been applied to therapy in form of CBT
E - all cognitive aspects of depression can be identified + challenged in CBT. These included components of negative triad that r easily identifiable. Such therapy consistently been to found best depression treatment
I - if depression is treated by challenging thoughts - have role in causing depression

48
Q

Ellis ABC model Evaluation ( not irrational)

A

P - not all irrational beliefs r irrational
E - eg alloy + Abrahamson (1979) found depressed propel have more accurate estimates of likelihood of disaster than non depressed people - sadder but wiser effect.
E - s depressive realists tend to see things for what they r, rather than seeing things thro rose coloured glasses
I - some irrational beliefs may seem irrational than be irrational

49
Q

Ellis ABC model Evaluation ( reactive)

A

P - some cases follow activating event
E - psychologist call this reactive depression and see it as a different from the kind of depression that arises without any obvious cause
E - Ellis explanation only applies to some kind of depression and therefore only partial explanation for depression
I - decreases validity as an explanation for all depression cases

50
Q

Ellis ABC model Evaluation ( successful therapy)

A

P - explanation led to successful therapy
E - idea that by challenging irrational beliefs a person can reduce depression Is supported by evidence like Lipzky (1980).
E - in turns support basic theory as it suggest that irrational beliefs had some role in depression
I - this led to successful treatment of CBT, which uses a key element of challenging thoughts.

51
Q

Cognitive approach evaluation (genetic factors + neurotransmitters)

A

P - explained in terms of neurotransmitters + genetic factors
E - eg studies have found low levels of neurotransmitters serotonin in depressed people and gene related to this is 10x more common in depressed people
E - may better to take diathesis-stress model approach where development of depression looks at biological + cognitive explanations
together
I - cognitive factors r not only explanation for depression

52
Q

Cognitive approach evaluation (limited explanation )

A

P - don’t explain all aspects of depression
E - some suffers of depression experience hallucinations + bizarre beliefs (cotard syndrome - belief zombies r real)
E - becks theory explains basic symptoms of depression but not more complex ones. Ellis model explains why some people r more vulnerable than other but then doesn’t explain anger some indiv feel or their hallucinations and delusions
I - other explanations may be needed to explain condition in full

53
Q

Becks CBT

A

Aim to identify automatic thought about world, self + future (negative triad). Once identified, thoughts challenged. Patients given hw, used in future sessions by therapist to disapprove negative automatic thoughts + give some responsibility to patients (eg record their emotion in journal)

54
Q

Ellis’ Rational Emotive Behaviour Therapy (REBT)

A

Aims to turn irrational thoughts into rational thoughts and resolve emotional + behav problems. Expanded to ABCDEF, D is disputing irrational thoughts + beliefs. E is effects of disputing + effective attitude to life. F is new feelings that r produced
REBT focuses on vigorous argument to dispute irrational thoughts + replacing them with effective rational beliefs which produce new feelings. Different methods for dispute - logical, empirical + pragmatic disputing r ways of challenging irrational thoughts + beliefs and replacing them with more rational thoughts + beliefs

55
Q

Empirical Argument

A

Disputing whether there is actual evidence to support negative belief

56
Q

Logical argument

A

Disputing whether negative thoughts logically follow the acts

57
Q

Behavioural activation

A

Used in CBT. Involves encouraging patient to be more active + engage in enjoyable activities. Provide more evidence for irrational nature of beliefs

58
Q

CBT Evaluation ( supporting research)

A

P - research shows CBT is effective treatment for depression
E - march (2007) compared effect of CBT with antidepressants drugs and combination of the 2 in 327 adolescents with main diagnosis of depression. After 436 weeks, 81% of CBT group, 81% of antidepressants group + 86% of combined therapy group were significantly improved
E - shows CBT is as effective as medications at treating depression and most effective treatment is combination of biological + cognitive therapy
C - however Also seen more effective with antidepressants so CBT isn’t effective alone

59
Q

CBT evaluation (overemphasised)

A

P - overemphasis importance of cognition
E - risk that because of its emphasis on what is happening mind of individual patient CBT may end up minimising important r of circumstances in which a patient is living
E - eg person suffering from addiction/poverty may need to change their situation rather than focus on thoughts. May focus so heavily on what’s happening in patients mind that they demotivate them to change their situation
I - limits usefulness of CBT as it’s not effective treatment for all real life circumstances and only for a narrow range

60
Q

CBT evaluation ( exercise)

A

P - some other methods r more effective in treating depression
E - research shows exercise can beneficial in alleviating depression. Babyak found aerobic exercise, anti depressant drugs or both together treat depression effectively
E - however there was significantly lower relapse rates following exercise than drug treatment
I - shows exercise used in behavioural activation part of CBT can be highly effective

61
Q

Behavioural characteristics of OCD

A

Compulsive behaviour
Compulsions repetitive - compelled to repeat behaviour
Compulsions reduce anxiety - 10% OCD sufferers show compulsive behav + no obsessions
Avoidance

62
Q

Emotional characteristics of OCD

A

 anxiety + Distress - obsessive thoughts are frightening and anxiety can be overwhelming (urge to repeat to repeat behav)
Depression — low mood and get lack of enjoyment out of activities
Irrational guilt over minor issues
Disgust - direct to external things like dirt/themselves

63
Q

Cognitive characteristics of OCD

A

Obsessive thoughts - 90% of OCD sufferers have, major cognitive feature is repetitive, different to each indiv but always unpleasant
Cognitive strategies - adopted to deal with obsessions + manage anxiety associated with them e.g. praying
Insight into excessive anxiety - aware obsessions + compulsions are irrational (symptom needed for diagnosis)

64
Q

Genetic explanation definition

A

Focus on role that genes play in mental disorder development. As genes make up chromosomes and consist of DNA, codes psychological features. Transmitted from parents of spring (inherited)

65
Q

Neural explanation definition

A

Focus on structure and function of brain and nervous system in mental disorder development

66
Q

Genetic explanation (indiv vulnerability)

A

Involved in individual’s vulnerability to OCD. Lewis (1936) observed his OCD patients - 37% had parents + 21% had siblings with OCD. S runs in families - the genetic vulnerability runs in families than genes to definitely produce OCD. Diathesis dress models s certain genes leave some indiv more likely to suffer mental disorder - not certain. These indiv need some environmental stress trigger OCD

67
Q

Genetic explanation ( candidate genes)

A

Researchers found candidate genes create vulnerability for OCD.  some genes involved in regulating serotonin system development. One gene thought to be involved in OCD vulnerability is 5HTI-D, involved in efficiency of serotonin transport across synapses

68
Q

Genetic explanation (poly genic)

A

OCD is polygenic - it’s caused by one single gene but several. Taylor (2013) analysed previous study findings and found evidence that 230 different genes involved in OCD. These genes are associated with dopamine and serotonin action. Both have a role in regulating mood

69
Q

Genetic explanation (aetiologically heterogeneous)

A

OCD is aetiologically heterogeneous, Origin of OCD has different causes. One group of genes may cause OCD in one person but different groups of genes may cause OCD in another person. Evidence are different types of OCD like hoarding maybe due particular genetic variations

70
Q

Genetic explanation evaluation (flawed genetic evidence)

A

P - flawed twin studies
E - Standard source of evidence for genetic influence but assume identical twins only more similar then non-identical twins according to genes.
E - Overlook identical twins may be similar according to shared environments E.g. non-identical twins might be a boy and girl who have different experiences
I - reduces value of twin studies as evidence doesn’t separate effective nature and nature on OCD reducing supporting evidence for genetic explanation of OCD

71
Q

Genetic explanation evaluation (support of evidence VS environment )

A

P - support is evident from variety of sources that some people more vulnerable to OCD due to genetic make up
E - Nestadt (2010) Reviewed previous twin studies and found 68% of identical twin shared OCD opposed to 31% of non-identical twins.  S that there is a genetic influence on OCD
C -  Evidence environmental factors trigger or increase risk of developing OCD
E - Cromer (2007) Found over half OCD patients in Temple a traumatic event in the past and OCD was more severe in those with more than one trauma. s OCD can’t be entirely genetic origin. more productive to focus on environmental causes as more able to do something about this

72
Q

Genetic explanation evaluation (no gene identification )

A

P - despite twin studies suggesting OCD largely genetic psychologist not successful in identifying genes involved
E - 1 reason for it because several genes involved in OCD and each genetic variation increases OCD by fraction
E - consequence is that genetic explanation unlikely to be useful as provide a little predictive value about whether individual will develop OCD and what type

73
Q

Neural explanations (serotonin system)

A

Some OCD cases explained by reduction in functioning of serotonin system in brain so less produced. Serotonin - neurotransmitter for regulating mood. Low serotonin means normal transmission of mood relevant information between neutrons don’t take place and mood and other processes affected

74
Q

Neural explanations (dopamine levels)

A

Dopamine levels thought to be abnormally. high in OCD patients high dose of drugs that enhance levels of dopamine in animals induce stereotyped movement resembling compulsive behaviour found in OCD patient

75
Q

Neural explanations (lateral frontal lobes)

A

Decision making occurs in lateral frontal lobes. Abnormal functioning in frontal lobes leads to impaired decision-making. Impaired decision-making thought to be responsible for hoarding disorder

76
Q

Neuro explanations (parahippocampal Gyrus)

A

Left parahippocampal gyrus - May be involved in OCD m, area of brain associated with processing unpleasant emotions, found to function abnormally in those with OCD

77
Q

Neural explanation evaluation ( serotonin)

A

P - Evidence for serotonin role in OCD from research examining antidepressants
E - research found drugs increasing level of serotonin are effective in treatment of OCD patients. types of antidepressants that don’t work on serotonin system have no effect on OCD as serotonin is directly involved in OCD
C - serotonin OCD link maybe comorbidity with depression people who suffer OCD may become depressed.
E - depression probably involves disruption to serotonin system, could be that those individuals with OCD have disrupted serotonin system because they are depressed

78
Q

Neural explanation evaluation (unclear neural mechanisms)

A

P - Not clear which neuron mechanisms are involved in OCD
E - cavedini (2002) looked at decision-making, found neural systems involved in decision-making is the same as systems functioning abnormally in OCD patients. S that these Brain areas + their abnormal functioning are implicated in OCD
C - Research also identified other brain systems are involved in OCD sometimes. problem is no brain system found to always play a role in OCD. we don’t know which newer systems are involved in OCD development

79
Q

Neural explanation evaluation (assuming neuromechanisms role in OCD)

A

P - shouldn’t be assumed neural mechanisms cause OCD
E - evidence S various neurotransmitters and brain areas don’t function normally in OCD patients
E - However not same as saying this abnormal functioning causes OCD
