Q

limitations of statistical deviation

A

abnormality is sometimes desirable e.g higher IQ levels

cut off pointe are subjectively determined e.g based on self reports .

if somebody is happy and fulfilled there is no benefit in labelling them as abnormal may negatively effect them.

Q

strengths of statistical deviation

A

it uses scores on well established standardised tests so it is more objective and scientific

it uses an objective point of two standard deviations to define abnormal behaviour

Q

limitations of deviation from social norms

A

social norms vary over time e.g homosexuality was a mental disorder until 2000

norms are culturally relative

ethnocentric bias might effect perceptions of normality within a society that has ethnic minorities

Q

define failure to function adequately as a definition of abnormality

A

an individual can be classified as abnormal when they can no longer cope with the demands of every day life

(Rosenhan and seigman personal dysfunction features - conformity , personal distress , irrational/dangerous behaviour to them self or others)

Q

limitations of failure to function adequately as a definition of abnormality

A

difficult to say when somebody is failing to function when they are just deviating from social norms e.g people live alternative lifestyles , classifying them as abnormal could discriminate against some groups

some abnormal behaviour can be functional

Q

limitations of deviation from ideal mental health as a definition of abnormality

A

sets unrealistically high standards for mental health - unobtainable for a lot of people how many does a person need to lack before being “abnormal”

definition is specific to western european and north american culture

subjective judgments are required to assess the functioning , what is a realistic view of the world ?

A

phobias are an anxiety disorder , they are all characterised by excessive fear and anxiety and are triggered by an object , place or situation . The extent of fear is out of proportion to any real danger presented by the phobic stimulus

Q

what are cognitive characteristics

A

refers to the process of thinking knowing and perceiving

27
Q

what are behavioural characteristics of phobias

A

PANIC- (cry scream , run away , freeze , cling , tantrums)

Avoidance or stimulus

endurance (remain in the presence of it but experience high anxiety, only possible when avoidance is not possible)

28
Q

what are emotional characteristics of phobias

A

anxiety (unpleasantly high state of arousal)

fear when in contact or thinking about phobic stimulus (immediate and unpleasant response)

unreasonable emotional response

29
Q

what are the cognitive characteristics of phobias

A

irrational beliefs

cognitive distortions (e.g seeing the stimulus as alien ugly disgusting or agressive looking)

selective attention to phobic stimulus

30
Q

what is the two process model in terms of being a behavioural explanation for phobias

A

the two process model is based on the behavioural approach to phobias , a phobia is acquired through classical conditioning and maintained through operant conditioning.

31
Q

how are phobias acquired according to a the two process model , a behavioural explanation

A

acquisition of phobias is through classical conditioning

Learning to associate something of which we initially have no fear (neutral stimulus) with something that alrwady triggers fear (an unconditioned stimulus)

UCS- produced a fear response
UCS associated with NS
NS becomes a CS
CS produces a CR of fear when presented

e.g little albert study

32
Q

how are phobias maintained according to the two process model , a behavioural explanation for phobias.

A

maintenance of phobias takes place through operant conditioning

operant conditioning takes place when our behaviour is reinforced or punished , Reinforcement increases the likelihood behaviour will continue , in negative reinforcement an unpleasant stimulus is removed or avoided which results in a desirable consequence.

  • Mowrer suggested that whenever we avoid a phobic stimulus we successfully escape the fear and anxiety that we would have suffered if we remained there , this reduction in fear reinforces the avoidance of the behaviour so the phobia is maintained.
33
Q

give a strength of the two process model of phobias

A

phobias are maintained through avoidance of thr phobic stimulus and negative reinforcement , we therefore know when treating the phobia we need to come into cons for with the stimulus rather than avoiding it. helps us develop treatments e.g flooding and systematic desensitisation

34
Q

give another strength of two process model as an explanation for phobias

A

there is supporting evidence little albert study

35
Q

limitation of two process model as an explanation of phobias

A

conditioning is not the only way feaes are acquired some phobias havw an evolutionary aspect - biological preparedness

36
Q

what are the two behavioural treatments for phobias

A

systematic desensatisation (SD)

flooding

37
Q

explain how systematic desensitisation works as a behavioural treatment for phobias

A

sysetmatic desensitisation works through reciprocal inhibition .
Anxiety hierarchy- list of situations ranked for how much anxiety they produce.

Relaxation- including imagery and breathing techniques or sometimes medication.

Exposure- gradual exposure to phobic stimulus whilst relaxed at each stage of the hierarchy.

works through classical conditioning if the sufferer can learn to relax in the presence of their phobic stimulus they will be cured.

38
Q

define reciprocal inhibition

A

reciprocal inhibition is the idea you cant be physiologically scared and relaxed at the same time.

39
Q

explain how flooding works as a behavioural treatment for phobias

A

flooding involves immediate exposure to the phobic stimulus.

flooding: works though extinction.

Exposes patients to a very frightening situation without a build-up.

Learned response is extinguished when CS is encountered without the UCS. It will then no longer produce the CR of fear.

Ethical safeguards- patients must give informed consent to and be prepared for flooding.

40
Q

outline one strength of systematic desensitisation as a behavioural treatment for phobias

A

it can be a very effective treatment

Barlow et al found success rates of between 60-90% for specific types of phobias when individuals committed to the phobias and stuck to the regime.

positive because this therapy is effective at removing the symptoms of a disorder without the need for potentially damaging drugs (anti-anxiety drugs would be given within the Biological approach) which often cause many side effects (e.g. drowsiness, risk of addiction).

41
Q

outline one limitation of systematic desensitisation as a behavioural treatment for phobias - ethical issues

A

it is more ethical than flooding but may still cause some distress .
clients are subjected to their most feared situations in techniques such causing some clients to experience very high levels of distress.

This is a weakness because clients may not stay in therapy and may actually leave the therapeutic situation in a worse state than when they began due to the potential for high levels of distress.

42
Q

outline one strength of flooding as a behavioural treatment for phobias - cost effective

A

it is cheaper than systematic desensitisation , evidence suggested by craske et al found SD and flooding have similar effectiveness.

flooding requires less sessions so is cheaper and more favourable as iy is more cost effective.

43
Q

outline one limitation of flooding as a behavioural treatment for phobias - susbsitution

A

)Removing symptoms of a phobia does not mean removal of the cause- symptom substitution can occur.

44
Q

outline one limitation of flooding as a behavioural treatment for phobias - ethical issues

A

can be more traumatic than sd , not a gradual exposure its immediate , if the client cant stick to trhe regime the phobia may acc become worse.

45
Q

define OCD

A

Obsessive compulsive disorder is characterised by either obsessions and/or compulsive behaviours. Most people with a diagnosis of OCD havw both obsessions and compulsions

46
Q

outline the emotional characteristics of OCD

A

anxiety and distress - unpleasant overwhelming feelings

accompanying depression -

guilt and disgust - irrational guilt

47
Q

outline the cognitive characteristics of OCD

A

obsessive thoughts - eg reoccurring thoughts , always unpleasant

cognitive strategies to deal with obsessions - to help manage anxiety

insight into excessive anxiety - they are aware their obsessions and compulsions are not rational . tend to be hyperviggilant

48
Q

outline the behavioural characteristics of OCD

A

Compulsions :

  • compulsions are repetitive - feel compelled to repeat a behaviour
  • compulsions reduce anxiety - vast majority of compulsive behaviours are carried out to manage anxiety produced by obsessions

Avoidance :

  • sufferers of OCD tend to try and manage their OCD by avoiding situations that trigger it
49
Q

outline the genetic behavioural approach to explaining OCD

A

-Lewis found that 37% of OCD patients had parents with OCD and 21% had siblings with OCD- this shows genetic vulnerability is passed through generations

  • candidate genes create vulnerability for OCD
    e. g 5HT1-D beta - involved in regulating the development of the serotonin system .
  • Taylor found OCD is polygenic - up to 230 genetic variations
  • aetiologically heterogeneous- one grouo do genes may cause OCD in one person but another group of genes may cause the disorder in another person .
  • according to the diathesis-stress-model certain genes leave some people more likely to suffer a mental disorder but it is not certain , some environmental stress (experience)is necessary to trigger the condition
50
Q

outline the neural behavioural approach to explaining OCD

A

low levels of serotonin are associated with OCD

  • some forms of OCD have been associated with impaired decision making and difficulty processing unpleasant emotions -
    abnormal functioning in lateral side frontal lobes
    left parahippocampal gyrus may be malfunctioning - difficulty processing unpleasant emotions
51
Q

outline one strength of the biological approach to explaining OCD - supporting study

A

nestadt found that 68% of identical twins shared OCD whereas 31% of non identical twins shared it

this strongly suggests genetic influence on OCD

52
Q

outline one limitation of the biological approach to explaining OCD - predictive value - number of genes

A

psychologist have not been successful at understanding all or the genes involved in OCD .

there are several genes involved and waycg only increases the risk of OCD by a fraction

the genetic explanation is unlikely to be useful as it provides little predictive value - not useful for developing treatments

53
Q

outline one strength of the biological approach to explaining OCD - antidepressants

A

antidepressants that work on the serotonin system eg SSRI , to increase level of serotonin are effective in reducing OCD symptoms

this shows that the serotonin system is involved in OCD

54
Q

outline one limitation of the biological approach to explaining OCD - is it a result of OCD or a cause

A

suggesting that various neurotransmitters and structures of the brain do not function normally in patients with OCD is not the same as saying they cause OCD

these biological abnormalities could be as a result of OCD rather than a cause

55
Q

outline one limitation of the biological approach to explaining OCD - diathesis stress model

A

the diathesis stress model shoes environmental factors can trigger or increase risk of developing OCD

Cromer found that over half the OCD patients had traumatic past events and OCD was more severe in those with more than one trauma .

this shows it cannot be entirely genetic in origin it might be better to focus on environmental causes because we can do something about them

56
Q

outline biological treatments for OCD

A

biological explanations for OCD imply that biological treatments may be successful , most obviously through drug treatments that target abnormal neurotransmitter levels

people with OCD havw low serotonin levels
SSRI - are used

57
Q

What does SSRI stand for

A

selective serotonin reuptake inhibitors

58
Q

how do SSRIs work to biologically treat OCD

A

low levels of serotonin are associated with OCD

Neurotransmitters (serotonin) is released to the synapse to travel to the next neuron . the serotonin left begging can either be reabsorbed by the presynaptic neuron or be destroyed by enzymes

by preventing the re - absorption and breakdown of serotonin - SSRI effectively increase its levels in the synapse and continue to stimulate the postsynaptic neuron

59
Q

how are SSRI’s used to treat OCD inc dosage

A

they are antidepressants that prevents the reabsorption ans breakdown of serotonin

the typical dose of fluoxetine is 20mg a day but this can be increased

drugs are capsules or liquids

it can take up to 3 - 4 Months for them to work- when a SSRI is not effective after this time the dose can be increased to 60mg a day fluoxetine or combined with other drugs

they can also be combined with CBT to reduce a patients emotional symptoms of OCD e.g depressed/anxious

60
Q

outline two drug alternatives that may be used if SSRIS don’t work

A

tricyclics
- older type of antidepressant e.g clomipranine - has the same effect on the serotonin system as SSRIs but has more severe side effects so it is kept for patients who don’t respond to SSRIS

SNRIs
-serotonin-nonadrenaline inhibitors . - different class of antidepressants, they increase levels of serotonin as well as another different neurotransmitter, nonadrenaline
61
Q

outline one strength of the biological approach to treating OCD - supporting evidence

A

soomro et al reviewed studies comparing SSRI’s to placebo effects

concluded that all 17 studies showed SSRIS had significantly better results for the SSRIs than the placebo

effectiveness was greatest when SSRIs were combined with CBT.

typically symptoms decline for around 70% of patients taking SSRI

62
Q

outline one strength of the biological approach to treating OCD - cost effective and non disruptive

A

drugs are cheap compared to psychological treatments , which is good value for public services (NHS) they are also non disruptive to patients lives , you could fake drugs until your symptoms decline and not engage with the hard work of psychological therapy

63
Q

outline one limitation of the biological approach to treating OCD - side effects

A

SSRI can havw side effects such as ;

indigestion
blurred vision
loss of sex drive

although they are temporary they may put people off using them

clomipramine side effects are more common and more serious :

more than 1 in 10 parents suffer 
weight gain 
erection problems 
tremors 
disruption to blood pressure and heart rhythm

such factors reduce effectiveness because people stop taking the medication.
