Q

What is a strength of statistical infrequency as a definition of abnormality?

A

S- good real world application- helps professionals to diagnose people with a disorder and shows how severe it is. For example, if you score under 70 on an iq test or over 40 on Beck’s depression meter you can be helped more easily

Q

What are limitations of statistical infrequency as a definition for abnormality?

A

L- can give people an unnecessary label- for example if a person has an iq over 135 they are technically abnormal and don’t need a label as it could come with negative stigma. This can also be said with people with an iq under 70.

L- some behaviours are not statistically infrequent but still need treatment- depression effects 27% of elderly people but this doesn’t mean they don’t need help.

L- where is the cut off point?- for example why is an iq under 70 seen as manageable but an iq of 69 means someone requires help

Q

What are the strengths of the behaviourist explanation for phobias?

A

S- real world applications- the two-process model of classical and operant conditioning lead to the development of systematic desensitisation and flooding

S- supporting evidence- Ad De Jongh found that 73% of people with a phobia of thr dentist had past trauma. This compared to people who didn’t have a fear of the dentist who only 21% had had a traumatic experience in the past

Q

What are limitations of the behaviourist explanation of phobias?

A

L- floored design- not all phobias come from a traumatic experience. For example some of the most common phobias in the UK are snakes and sharks but no one has a phobia of cars which kill way more people.

L- states all phobias come from direct experience. Whereas some phobias such as the dark are inherited so have a biological explanation

Q

What are the strengths of systematic desensitisation?

A

S- supporting evidence- Gilroy followed 42 people with a phobia of spiders who had 3x45 mins sessions of SD compared to those who had basic relaxation therapy and 3 years later the people who did SD were less scared than the control group

S- can he used for everyone- ideal for younger children or people with mental disabilities as is more gradual and can be stopped at any time

S- applies to all phobias- virtual reality can be used for fears such as heights.

Q

What are the limitations of SD?

A

Q

What are two strengths of the cognitive theory of depression

A

S- supporting research for Becks’s theory- Cohen tracked the development of 473 adolescents and monitored levels of ‘cognitive vulnerability. The more ‘vulnerable ones’ were more likely to get depression.

S- real world application for Ellis- lead to REBT. Vigorous arguments is effective

42
Q

What are two limitations of the cognitive theory of depression

A

L- ethical issues associated with ABC model (beck)- blames patients ‘irrational thoughts’- this may upset and be unhelpful to a person with depression

46
Q

What are the limitations of CBT therapies

A

L- drugs better- March found that both CBT and drug therapy helped 81% of people and drugs are cheaper and less time consuming

L- not effective- Ali assessed 439 patients every month for 12 months and found - 42% relapsed within 6 months, 53% relapsed within a year

47

21% of people with OCD had a sibling with OCD

51
Q

What did Taylor find about OCD genes

A

There are over 230 genes that cause OCD

52
Q

What are the strengths of genetic explanations of OCD

A

S- supporting evidence- Lewis study- Nestadt found 68% of identical twins shared OCD as opposed to 31% non identical twins

53
Q

What are the limitations of genetic explanations of OCD

A

L- only partly genetic- should be 100% not 68%

L- Cromer found 50% of people with OCD underwent a traumatic event

54
Q

what experiment supports the behaviourist approach to phobias (two-process model)

A

little Albert

55
Q

what was little Albert afraid of after the experiment

A

cotton wool, Watson's hair and a Santa Claus mask

56
Q

what is the two process model

A

phobias are attained by classical conditioning but maintained by operant conditioning

57
Q

how does operant conditioning maintain phobias

A

negative reinforcement when phobic stimulus is avoided

58
Q

what is the cognitive theory of depression

A

assumes that thinking, expectations and attitude (cognitions) direct behaviour. Mental illness is the result of disordered thinking. The issue is not the problem itself, but the way you think about it.

59
Q

what are the three components of Beck's cognitive theory of depression

A

faulty information processing

negative self-schema

negative triad

60
Q

what are the two different types of disputes that can be made in REBT

A

empirical argument

logical argument

61
Q

what is empirical argument

A

'is there any evidence to support your belief'

62
Q

what is logical argument

A

'is your belief logically follow form the evidence'

63
Q

what is the 5HT1-beta gene and how does it link to OCD

A

a mutation of this gene leads to the reuptake of serotonin in synapses causing a person to have lower levels of serotonin

study showed that in two families with this mutation present 6 of 7 had OCD

64
Q

what did Nesdadt find about OCD concordance rates

A

revised twin studies

68% of MZ twins both had OCD

31% DZ twins both had OCD

65
Q

what did Cromer find about OCD (Diathesis stress)

A

50% of people with OCD had suffered a traumatic event

66
Q

what are the neural explanations of OCD

A

neurochemistry

neuroanatomy

67
Q

what is the role of serotonin in OCD

A

many with OCD have lowered serotonin (5HT1-beta) causing lowered mood

68
Q

how do SSRI's (anti-depressants) help OCD (neural)

A

increase levels of serotonin

69
Q

how does the prefrontal cortex link to OCD

A

located in frontal lobes which are associated with logical thinking and decision making

in those with OCD the PFC often functions abnormally (over active) leading to compulsive and repetitive behaviour

70
Q

how does the left parahippocampal gyrus link to OCD

A

PHG linked with processing unpleasant emotions

found to be abnormal those with OCD

71
Q

what are the limitations of neural explanations of OCD

A

comorbidity- OCD and depression often diagnosed together. problem as unclear if lack of serotonin is to do with OCD or just depression

hard to establish cause and effect- unclear if structural abnormalities cause OCD or the other way around

72
Q

how do SSRI's work

A

block receptors which reuptake serotonin, forcing it to diffuse across synapse.

73
Q

what are the effects of combining SSRI's with CBT

A

drugs reduce emotional symptoms such as anxiety and depression which makes the therapy easier

74
Q

what are the alternatives to SSRI's

A

tricyclics

SNRI's

75
Q

what are tricyclics

A

used before SSRI's

work in the same way

more severe side effects (low blood pressure, vomiting, blurred vision etc)

clozapine is an example

76
Q

what are SNRI's

A

work in same way but work on noradrenaline as well

developed in last decade

77
Q

what are the strengths of biological treatments (drug treatments) for OCD

A

supporting evidence- Soomro reviewed 17 studies where SSRI's were compared to placebo's and found- SSRI's worked better than placebo 100% of the time, 70% had reduced symptoms on SSRI's

easier- more cost effective, shorter waiting lists for NHS, some people with OCD may not want to do therapy due too fear of germs etc

78
Q

what are the limitations of biological treatments (drug treatments) for OCD

A

contradictory evidence- Skapinakis found in a meta-analysis that SD and flooding were more effective in treating OCD than SSRI's

side effects- SSRI's can cause blurred vision, indigestion and low sex drive. Tricyclics can cause aggression and heart problems. this decreases quality of life and deters people from taking them

79
Q

why can the behaviourist approach to explaining phobias be seen as overly simplistic (AO3)

A

doesn't explain the cognitive factors such as irrational beliefs and cognitive distortions

80
Q

what is reciprocal inhibition in SD

A

part of relaxation- when a person cannot be both scared and relaxed simultaneously

81
Q

what is the aim of flooding

A

'extinction'

conditioned stimulus present unconditioned stimulus not

82
Q

why is ethical safeguarding important in flooding

A

informed consent vital as traumatic

SD offered as well

83
Q

Why is CBT and REBT not suitable for all (AO3)

A

doesn't work for severe depression as people don't engage

Stevey- 'any form of psychotherapy is unsuitable for those with learning difficulties'

84
Q

why is CBT and REBT suitable for everyone (AO3)

A

Taylor sash it was suitable for those with learning difficulties

lewis said it was suitable for severe depression

85
Q

what is supporting evidence for biological explanations of OCD (AO3)

A

Nesdadt found 68% of peoples who's parents had OCD had OCD and same with 31% with siblings. Stebanicki found if a family member had OCD a person is 4 times more likely to get it


SSRI's work on OCD. also people with Parkinson's show symptoms of OCD (nesdadt)

86
Q

how many months does a person need to take SSRI's for before they are effective for ocd

A

3-4

87
Q

what is the average dosage for SSRI

A

20 mg

88
Q

what are the side effects of cloripramine (AO3)

A

1 in 10 gain weight

1 in 100 have heart problems

89
Q

why is research into drug treatments for OCD biased (AO3)
