definitions for abnormality - statistical infrequency (weaknesses)

A

not all infrequent behaviours are abnormal e.g. high IQ is desirable

not all abnormal behaviours are infrequent - some frequent behaviours are abnormal e.g. 10% of the population have depression

Q

definitions for abnormality - deviation from social norms (weaknesses)

A

people regularly break social norms but seen as ‘eccentric’ instead

norms change over time e.g. homosexuality seen as mental illness till 1990 - can’t truly define act as abnormal as society changes so must our behavioural beliefs

Q

Social Phobia

A

social anxiety disorder
fear of social situation through thought they may be judged / embarrised

20
Q

Agrophobia

A

irrational fear of being in places where escape if difficult
e.g. crowded spaces, leaving home

21
Q

Specific Phobias

A

phobia of specific object

22
Q

Phobia - emotional characteristics

A

anxiety / panic
excessive / unreasonable fear to stimulus

23
Q

Phobia - behavioural characteristics

A

freezing / fainting
avoidances interfering with life

24
Q

Phobia - cognitive characteristics

A

irrational thinking
resistant to logical thinking
awareness of own irrationality

25
Q

The Behaviourist Explanation for Phobias:

A

Little Albert
white rate = neutral stimulus and elicits neutral response
bang unconditioned it naturally produces fear
bang & rat paired
rat becomes conditioned stimulus which elicits conditioned response (fear)

26
Q

Behaviourist Approach to Treating Phobias: Flooding

A
  1. Relaxation (taught e.g. breathing exercises, visualisation, progressive muscle relaxation)
  2. Flooding/Intense Exposure (introduced to phobic stimulus at its worst whilst using relaxation techniques called reciprocal inhibition) (2-3 hour sessions gives fear response chance to pass) (once calm, neural experience with phobic stimulus so unlearns association) (involve vitro (imagined) or vivo (contact)
27
Q

Behaviourist Approach to Treating Phobias: Systematic Desensitisation

A
  1. Relaxation
  2. Desensitisation Hierarchy/Gradual Exposure (gradually introduced to phobic stimulus whilst using relaxation techniques) (hierarchy series of agreed progressive steps) (usually vitro then move onto vivo) (several shorten sessions online or self-administered)
28
Q

Evaluation of the behaviourist treatment to phobias: Flooding

A

+ similar effectiveness to alternate therapies
+ Choy et al: some evidence better than SD
- very intense not appropriate for everyone
- risk exposure backfire + make worse
- unethical: traumatic - risk people won’t turn up because of intensity wasting resources
- difficult and unethical to run alone/online

29
Q

Evaluation of the behaviourist treatment to phobias: Systematic Desensitisation

A

+ McGrath et al: 75% success rate
+ Choy et al: vivo more effective
+ works in long-run (Gilroy et al: patients less afraid of spiders than control group at 3-year follow-up after 45’ session)
- not appropriate for all phobias (ancient fears best treated by flooding)
+ allows patient buy-in since they agree on steps - their pace so little distress or drop-outs
+ self-administered & done online - cheap & widens access to those who can’t access conventional therapy

30
Q

Obsessive Compulsive Disorder

A

anxiety disorder
obsessions: reoccurring + persistent thoughts
compulsions: repetitive behaviours

behavioural: compulsions
cognitive: obsessions
emotional: anxiety, disgust, shame

31
Q

Genetic Explanation to OCD

A

genetic basis: heritable
investigated through family (fam rates of OCD to calculate risk), twin (look at twin with OCD to calculate concordance rates), gene (study DNA sequences to identify which variant (mutation) of particular gene

32
Q

Evidence for the Genetic Explanation of OCD

A

Nestadt et al: those with first degree relatives have 5x risk - meta-analysis: MZ concordance rate 68% vs DZ 31%

specific genes discovered: COMT (controls production of COMT regulates dopamine (COMT mutation -> high dopamine -> OCD)) SERT gene (regulates serotonin transport (SERT mutation -> low serotonin -> OCD))

33
Q

OCD treatment: Selective Serotonin Reuptake Inhibitors (SSRIs)

A

OCD = low serotonin levels

tries to increase serotonin - CNSSRIs inhibit reuptake of serotonin - restores normal functioning of the OFC + caudate nucleus - relieves anxiety + obsessions

34
Q

OCD treatment: tricyclic antidepressants

A

inhibit reuptake of serotonin + noradrenaline TMT they remain in synapse increasing levels of serotonin + noradrenaline

more effective than SSRI but greater side effects e.g. insomnia, headache, upset stomach, loss of appetite

35
Q

OCD treatment: anti-anxiety drugs (benzodiazepines)

A

BZ alter GABA receptor function, GABA action enhanced

GABA has calming effect TMT BZ slow down neural signals + relax nervous system

work by increased chloride channel efficiency, enabling greater influx of chloride ions (negative) which decrease membrane potential + prevent firing

side effects: drowsiness, depression, vision problems

36
Q

evaluate strengths for drug therapy

A

evidence for effectiveness (show SSRI reduce symptom + improve QOL) (Soomro et al: reviewed 17 studies comparing SSRI to placebos - all showed sig better outcomes for SSRI) (symptoms reduce 70%) WEAKNESS (Skapinakis et al: systematic review of outcome + concluded both cog + beha therapies more effective in treatment)

cost-effective and non-disruptive (cheap compared to psychological treatments bc thousands of tablets/liquid doses can be manufactured in time it takes to conduct 1 session of psychological therapy - good value for public health systems (NHS)) (non-disruptive to lives)

37
Q

evaluate weaknesses for drug therapy

A

serious side effects (indigestion, blurred, loss sex drive) (those taking ticyclic clomipramine side-effects more common e.g. more than 1 in 10 people experience erectional problems + weight gain)

38
Q

cognitive explanation for depression

A

have schemas (about themselves or other people) that would affect how we process the world

39
Q

cognitive explanation for depression: Ellis’s ABC model

A

American psychologist who founded REBT (form of therapy)

if we react rationally, experience health emotions e.g. acceptance
if we react irrationally, experience unhealthy emotions e.g. hopelessness, worthlessness

Ellis proposed activating events interpreted with irrational belief, causes unhealthy consequence of depression - faulty belief: maladaptive thinking

40
Q

cognitive explanation for depression: Beck’s Cognitive Triad

A

-tive schemas acquired (often in childhood from rejection) provide -tive framework for viewing events pessimistically

these become biases: overgeneralisation, magnification, selective perception, absolutist think

41
Q

evaluate cognitive approach to depression

A

strengths:
+ supported by research (Hammen & Krantz: depressed people make logical errors in thinking tasks reinforcing cognitive bias of behaviour)
+ real world application (CBT)

weaknesses:
- ignores other approaches (genetics has evidence)
- correlation between -tive thoughts + depression but no causation

42
Q

alternative approaches to cognitive explanation for depression

A

Lewinsohn: operant conditioning - depression caused by removal of +tive reinforcement - reduction in activity + moods tends to cause others to express sympathy + give attention, -tively reinforcing depressed behaviour

monamine hypothesis of depression argues it results from low levels of serotonin

role of genetic factors: genes that influence activity of serotonin have been linked to depression (Zhang et al) - most researchers believe only creates vulnerability for depression - Caspi et al: depression only emerge if vulnerable individual experiences significant life stress

43
Q

cognitive approach to treating depression: CBT

A

identify -> challenge -> replace
identify dysfunctional thoughts -> challenge them -> test reality of irrational beliefs

set homework to record when enjoy event or someone nice to them, ‘patient as scientist’ investigation reality of -tive beliefs

behavioural activation (therapist encourages patient more active + engage enjoyable activities - provide more evidence for irrational nature of beliefs)

rationale: maladaptive thinking explains depression, psyc treat by working with patients to change thinking called ‘cognitive restructuring’ change way people interpret + process things by identifying, challenge, replacing - effortful + long-term solution

44
Q

research support for CBT: cognitive approach to treating depression

A

Ellis: 90% success rate for Rational Emotive Behavioural Therapy (REBT) - 27 sessions - not always effective

REBT & CBT done well in outcome of depression - Cuijpers et al: 75 studies CBT superior to no treatment

45
Q

cognitive approach to treating depression: CBT - individual differences (weaknesses)

A

less suitable for people high level irrational beliefs that are resistant to change (Elkin et al)

less suitable in situations high levels stress in individual reflect realistic stressors that therapy can’t resolve (Simons et al)
