Q

Biochemical explanation to OCD?

A

OCD responds well to seretonin

OCD seems to be related to low levels of seretonin (neurotransmitter) > SSRI anti depressants reduce OCD symptoms

Q

Neurophysiological explanation?

A

basal ganglia in OCD responsible for innate psychomotor functions

rapport and wise - hypersensitivity of the basal ganglia gives rise to repetitive motor behaviours e.g. ocd (compulsion)

Q

Evaluation/problems of biological?

A

genetic findings can be explained by environmental studies too
e.g. ocd sufferers with relatives > SLT observation and imitation

SSRI > only 50% improvement suggesting there is more than one explanation for OCD

therapeutic effect of SSRI doesn’t explain OCD

improvement in treatment won’t be noticed straight away

basal ganglia findings are inconsistent
aylward = no significant difference between OCD and control patients’ basal ganglia
> explains compulsion but not obsessions

Q

What’s the behavioural explanation of OCD?

A 
mower's two process theory of avoidance learning
classical condition (learnt) > operant conditioning (maintained)

Q

evaluation of OCD (behavioural)

A

two process theory can easily explain obsession and compulsion
short term > reduces anxiety
longterm > avoidance behaviour is learnt
avoidance conditioning theory > successful behavioural treatment
doesn’t explain how obsessions arise in first place

Q

evaluation of cognitive explanation for ocdv

A
  • cognitive bias (hyper vigilance) gives good account of individual differences
  • treatment of hyper vigilance > successful
  • concentrates on internal thoughts and -ignores socials factors that might contribute
  • ignores biological factors such as genetic or physiological basis

Q

psychodynamic explanation of ocd

A

psychosexual theory of development:
obsessions and compulsions come from unconscious conflict > id and ego > defense mechanism employed (compulsions): reaction formation (thinking and acting in opposite way to actual impulse)

dominant id - aggressive instincts (obsessions)

Q

salzman: psychodynamic approach of ocd?

A

salzman - ocd is a result of trauma > repressed into the unconscious > anxiety manifests via intrusive thoughts
obsessional thoughts > repressed memories surfacing into consciousness > compulsions are attempts to reduce anxiety by the consciousness

Q

evaluation of psychodynamic explanation of ocd

A

ocd relies on limited number of case studies > low validity as cannot generalise
no empirical evidence
moulded by childhood > defence mechanisms to defend ourselves from anxiety
not effective in treatment

Q

when do social phobias develop?

A

late childhood/early adolescence - affecting 11% men 15% women (kessler)

29
Q

types of agoraphobia?

A

as a complication of a panic attack - anxious about having a panic attack in public places where they will not be able to escape/find carerwithout panic attacks - spreading fear of the environment outside of the safety of their own home (housebound)

30
Q

types of explanations!! -

A

biologicalbehaviouralcognitivepsychodynamic

31
Q

Fyer’s study?

A

Fyer - first degree relative with phobias tend to be more likely to have one too. high concordance with specific phobiasno concordance with social

32
Q

problem with Fyer’s study?

A

social learning theory suggests that relative may be ablest observe and imitate behaviour therefore it is hard to separate biology from environment

33
Q

torgesen study?

A

investigated identical twins and fraternal twins - one of the pair was agoraphobic.higher likelihood the other twin had the same phobia in identical than fraternal suggesting genetic basis

34
Q

problem with torgesen study?

A

social learning theory - can’t separate environment from biologyobservation and imitation

35
Q

discuss vulnerability

A

eysenck - some people are more easily frightened by certain hints than others - high autonomic reactivity making them more likely to develop a phobia

36
Q

prepardness theory

A

seligman - phobias are from dangers/threats to us from 1000’s of years ago.preparedness to be sensitive to certain stimuliinnate tendency to develop phobias to harmful thingsbiologically prepared from birth

37
Q

problem with preparedness theory?

A

some people have phobias of something that poses no danger whatsoevercomes from conditioning animals to fear things in labs - low eco validity

38
Q

strength of preparedness theory

A

cook and mineka - monkeys acquired phobia of toy snakes easily compared to chairs suggesting there’s a genetic reason behind this

39
Q

problems with vulnerability theory?

A

different anxiety disorders have different reactions suggesting reactions in the autonomic system are more complicated than the theory suggests

40
Q

what’s the behavioural explanation to phobias

A

phobias are learnt by classical conditioning

41
Q

what’s the biological explanation to phobias

A

some people seem more susceptible to developing phobias than others suggesting there is a genetic basis to it

42
Q

what is the two process theory by mower?

A

learned phobia through classical conditioning which is maintained by operant conditioning - fear is reduced by avoiding the stimulus.two factory theory as it is incorporating classical and operantknown as avoidance conditioning

43
Q

study supporting behavioural explanation?

A

Watson’s study - albertrat and loud noise

44
Q

problems with little albert study?

A

-difficult to reproduce results mores with adults-findings have been inconsistent and small

45
Q

problems with behavioural explanation?

A

-doesn’t show how all fears are acquired-fear of dogs study di nardo-some phobias cannot be traced to bad experiences-sometimes occurs with no direct contact (hard to explain using conditioning theory)-just because no recollection of experience doesn’t mean there’s no environment involved = SLT suggests it can be learned vicariously through models

46
Q

what is the Di Nardo study?

A

dogs. 60% dog phobias are a result of a bad experience but the rest had no recollection of this.some people had a bad experience but did not acquire a phobia lol

47
Q

what is the cognitive approach on phobias?

A

fearful emotional response due to interpretation or appraisal of events-interpretation is distorted-automatic negative thoughts (ott)-over-generalising - one bad experience means all experiences will be bad

48
Q

three factors of cognitive explanation of phobias?

A

sensitisation = anxiety becomes associated with object/situation and triggers responseavoidance = sensitisation > avoidance of object > rewarding for imagenegative self talk/images = three distortions–overestimating –castastrophising–underestimating ability to cope

49
Q

cognitive approach to agoraphobia

A

-hypersensitivity to spacial layout-hypersensitive to being far away from a caretakerif access to home/carer is blocked > fear is induced > go home straight away

50
Q

how are social phobias maintained in the cognitive approach?

A

develop schemas > mental representationserving as a guide> includes mental thoughts of people being negative towards it> hypersensitivity to picking up cues from others they interpret negatively> behaviour is unacceptable and others will reject them> less able to socially interact and cycle occurs

51
Q

evaluation of cognitive explanation for phobias

A

practical therapeutic applicationstreatments are highly effectiveaccepts conditioning but also emphasises on persons thoughtsnot only driven by cognitions - maintained by inappropriate behaviour/avoidance

52
Q

psychodynamic explanation of phobias?

A

when ID impulses are repressed ad anxiety if displaced onto object. (oedipal and electra complex can be involved)

53
Q

examples of psychodynamic explanation on phobias?

A

Hans - freud.unresolved childhood issue > horses linked to fear of father and castrationSperling > fear of spiders is fear of sexual natureAbraham > fear of spiders symbolises fear os sexual genitalia

54
Q

evaluation of psychodynamic explanation of phobias

A

hans phobia is complicated? it’s not - there’s a simpler explanation > classical conditioninglacks methodical rigour > low validity as it is subjective and a case study (one person that cannot be used to generalise everything)freud suggested phobias were linked to sexual problems > WRONG

55
Q

drug therapy?

A

SSRI (selective sertonin reuptake inhibitors - anti depressant medications eg prozac.

56
Q

what does the SSRI do?

A

increases levels of seretonin in the brain by preventing reabsorption from happening at synapses so fast

57
Q

is SSRI effective? what if it isn’t?

A

good with panic and agoraphobia and generalised social phobia ( depressed accompanies OCD a lot)MAO - older anti depressants used when SSRI doesn’t work

58
Q

evaluation of drug therapy?

A

safe for patientsnot additivequick and cheapside effects - headaches nausea4-12 weeks for results > people may abandon themMAOI’s are panic blocking!!side effects for MAOI are :( weight gain etc

59
Q

behaviour therapies?

A

systematic desensitisationVRET (virtual reality exposure therapy)flooding

60
Q

what is systematic desensitisation?

A

Wolpe - fear is replaced with relaxation - anxiety heir achy ? relaxing at each stagein vivo - exposure in realityOCD is effective - if compulsions follow

61
Q

VRET?

A

virtual world version based on systematic desensitisation

62
Q

flooding

A

overwhelming patient with fear/ocd so they realise no harm comes to themimplosion therapy - imaginationexposure and response prevention - ocd version > not given chance to carry out compulsion

63
Q

evaluation of behaviour therapy?

A

systematic can be used when phobia is identified > cost effective > no good for OCD >doesn’t generalise to everyday lifeflooding > ethical implications > stress/anxiety levels > in vivo is more effective than exposure and responseexposure > more effective for ocd than medicationfret - like systematic desensitisation > expensive equipment > nausea

64
Q

cognitive therapy

A

replace unrealistic thoughts with realistic mental habits > identify, challenge and place counterproductive thoughts with more constructive ones

65
Q

what is the CBT study by graziano and mooney?

A

fear of dark with no treatment condition > taught to relax and praised for efforts > behavioural and cognitive approaches were used so….

66
Q

evaluation of cognitive therapy?

A

empirical evidence for cog therapy for anxiety when combined with behavioural techniquesmarks > ocd isn’t effected by cog muchany cognitive change could be helping so therapist man not be the reason??

67
Q

psychodynamic therapy

A

cause insight on why they have this phobia /ocdego defence mechanisms are taken away

68
Q

what are the ways of lifting ego defence mechanisms?

A

free association > conflict can be brought to surface if ego isn’t restraining thoughtshypnotisingdream analysis > ‘royal road to unconscious’ > repressed ideas are likely to come up in dreams to be interpreted > manifest content and stuff

69
Q

evaluation of psychodynamic therapy?

A

often ineffective making worseanxiety can be reduced without finding causeexpensive and time consumingtraumatic for patients > catharsis
