Q

statistical infrequency definition

A

behaviour that is numerically rare
being abnormal means it is far from the mean, median or mode

far extremes of normal distribution curve

2 or more standard deviations considered abnormal
example - intellectual disability disorder, IQ below 70 is rare

failure to function adequately

A

inability to cope with demands of everyday life

Q

failure to function adequately evaluation

A

+ real world application, can help people and considers patients perspective

Q

behavioural explanation for phobias

A

Mowrer’s Two process model
- learnt by classical conditioning
- NS paired with UCS, causes fear, NS becomes CS, leads to phobia
- maintained by operant conditioning
- negative reinforcement, avoiding phobia leads to relief of anxiety, makes phobic behaviours more likely
Little Albert

Q

behavioural explanation study (evidence)

A

Little Albert
association of white rusted with loud bangs
white rats became a CS when paired with UCS, loud bangs, causing CR, fear
generalised t other objects, white and fluffy

Q

evaluation of behavioural explanation

A

+ real world application, therapy, systematic desensitisation and flooding, prevents avoidance, effective
+ people can remember the cause of their phobia, conditioning
- not all bad experiences lead to phobias, Di Nardo et al 56% didn’t develop phobia
- phobia can develop without trauma, Di Nardo

Q

systematic desensitisation

A

counter conditioning - new positive associations
works by reciprocal inhibition - conflicting emotions can’t exist
eventual extinction

  1. learn relaxation techniques such as meditation
  2. hierarchy developed, most to least scary version
  3. gradual exposure, proceed up hierarchy once fully calm

Q

flooding

A

immediate, extreme exposure to phobic stimulus
fear response is exhausted (patient runs out of energy) and becomes extinct
prevents avoidance

18
Q

evaluation of systematic desensitisation

A

+ Gilroy et al, relaxation vs SD, updated at 3 and 33 months, SD group less fearful, shows it is effective long term

  • timely and costly, needs many sessions, disruptive
19
Q

flooding evaluation

A

+ cost effective as quicker, one long session
- less effective for social behaviours, so doesn’t help everyone
- Schumacher - therapist and pateint rate it significantly more stressful

20
Q

2 biological explanations for OCD

A

genetics and neural

21
Q

genetic explanation for OCD

A

inherited in genes
candidate genes predispose someone to OCD - gene 9 and SERT
OCD is polygenic - many genes involved which increase likely - Taylor, found 230 genes
etiologically heterogeneous - different groups of genes cause it is different people

22
Q

genetic explanation evaluation

A

+ Nestadt et al - MZ 68%, DZ 31% concordance rates
- too many candidate genes, not useful is predicting OCD
- not 100% for MZ
- environmental impacts, Cromer et al, 54% patients had trauma, OCD worse in those with multiple traumas

23
Q

neural explanation for OCD

A

abnormal levels of neurotransmitters such as low serotonin
or high dopamine

abnormal brain activity
scans show brain activity in OCD sufferers
hoarding linked to abnormal functions in lateral lobes
basal gangia = repetitive actions (compulsions)

24
Q

neural explanation evaluation

A

+ real world application, led to effective treatment of SSRIs, increase serotonin, Soomro et al, 17 studies show SSRIs more effective than placebo
- correlation doesn’t mean causation, OCD may cause abnormal levels (symptom not a cause)
- serotonin level may be low as they are also depressed

25
Q

biological treatments for OCD

A

drug therapy
increases levels of serotonin in synapse
SSRIs prevent reabsorption of serotonin, meaning more is transmitted
can be combined with CBT

26
Q

biological treatment evalauation

A

+ Soomro et al, 17 studies show SSRIs more effective than placebo, effective
+ cheaper and less disruptive than CBT
- drugs may have side effects such as blurred vision
- evidence may be biased as funded by drug companies who want to prove it works
- Cromer et al, OCD follows trauma, biological treatments wouldn’t work

27
Q

cognitive explanations for depression

A

Beck’s negative triad
depression caused by negative beliefs about world, self and future
negative self schema
depressed due to faulty information processing

Ellis’ ABC model
Activating event
leads to
Beliefs
has
Consequences
irrational beliefs leads to consequences such as depression

28
Q

evaluation of cognitive explanation

A

+ Grazoli and Terry, 65 pregnant women, those with faulty information processing more likely to develop PND, good supporting evidence
+ real world application, CBT
- reductionist, ignores other explanations such as biological and role of neurotransmitters
- depression doesn’t always follow an event

29
Q

cognitive treatments for depression

A

aims to change irrational thoughts

CBT
identify negative thoughts - ‘thought catching’
challenge the thoughts with help of therapist - hypothesis testing
test whether there are true - patient as scientist, given homework such as a diary
Cognitive reconstructing - reinforcement of positive thoughts

Ellis - ABCDE
Dispute = therapist challenges belief
Effect = irrational belief changed

30
Q

evaluation of cognitive treatments

A

+ March et al, 81% improved with CBT and 86% improved with CBT and drugs, shows its effective
+ self help strategy, in charge of own treatment, less ethical issues
- longer and more costly then drugs, Ellis averaged 27 sessions

31
Q

Rosenhan and Seligman

A

criteria to indetify if stone is unable to cope (FTFA)
includes personal and observer distress

32
Q

Jahoda

A

criteria needed for good psychological wellbeing
includes resistance to stress, self actualisation and self esteem

33
Q

Little Albert

A

given phobia of white rats (CS) by associating them with loud bangs (UCS) causing fear (CR)
generalised to white fluffy objects
supports behavioural explanation for phobias

34
Q

Di Nardo et al

A

56% of participants with bad experience of dogs didnt develop phobia
limitation of behavioural explanation, shows not all trauma leads to phobias

also not all patients can recall trauma leading to phobia

35
Q

Gilroy et al

A

relaxation vs SD
checked in at 3 and 33 months
SD group less fearful
support systematic desensitisation as shows it has long term benefits

36
Q

Schumacher

A

therapist and patient rate flooding significantly more stressful than SD
- limitation of flooding, traumatic

37
Q

Taylor

A

found OCD has 230 genes
show it is polygenic

38
Q

Nestadt et al

A

MZ twins - 68%
DZ twins - 31%
concordance rates of OCD in twins
supports that there is a genetic influence on OCD

  • however not 100%
39
Q

Cromer et al

A

54% patients had trauma
showed OCD was worse in those with multiple traumas
limitation of genetic explanation and treatment, shows there is an environmental influence and drug won’t work

40
Q

Soomro et al

A

17 studies show SSRIs more effective than placebo
supports biological treatments for OCD

41
Q

Grazoli and Terry

A

showed pregnant women with faulty information processing were more likely to develop post natal depression
supports cognitive explanation of depression

42
Q

March et al

A

81% improved with CBT
86% improved with CBT and drugs
supports cognitive treatment for depression
