Q

Why is it a disadvantage that statistical infrequency doesn’t take cultural differences into account ?

Q

What are the disadvantages of the deviation from mental health explanation?

What is positive reinforcement?
You are encouraged to repeat something by reward
26
What is negative reinforcement?
You are encouraged to repat something by removing the stimulus
27
What are the behavioural characteristics of phobias?
Panic Avoidance Endurance if they cannot get away
28
What are the cognitive characteristics of phobias?
Irrational thought processes Person knows that their fear is excessive Cognitive distortions Selective attention
29
What are the emotional characteristics of phobias?
Anxiety/fear out of proportion Unpleasant state of high arousal Prevents sufferer from relaxing
30
What is the two process model of phobias?
Phobias are developed due to classical conditioning but is maintained through operant conditioning
31
What is step one of the two process model?
Phobia is initially learned via classical conditioning
32
What is step two of the two process model?
Phobia is maintained via operant conditioning
33
What is a supporting study of the two process model?
Watson and Rayner-Little Albert Gains the fear of rats via CC but is maintained via OC, given cuddles when cries (Positive reinforcement)
34
What are the advantages of the two process model?
Practical application, flooding and sytematic desensitisation Has face validity Supporting study-Little Albert
35
What are the disadvantages of the two process model?
Theory has poor explanatory power, ignores the role of cognition Biological approach would disagree Bounton - Some phobias aren't learned but innate e.g. spiders
36
What is the behavioural approach to treating phobias?
Systematic desensitisation Flooding
37
What are the 3 steps to systematic desensitisation?
1. Anxiety hierarchy, phobic stimulus in order of most anxiety inducing 2. Patients are taught to relax 3. Patient is exposed to the bottom of the hierarchy an moves up
38
Who supports systematic desensitisation?
Gilroy - followed 42 patients, they had 3 45 minute sessions of systematic desensitisation. Spider phobia was assessed by a questionnaire. A control group was treated by relaxation without exposure. Experimental group were less fearful then the control.
39
What are the advantages of systematic desensitisation?
Supporting evidence-Gilroy Empowering for patient-control of the hierarchy Deal with the cause of the phobia rather than just medicating
40
What are the disadvantages of systematic desensitisation?
Require 1-1 sessions with a trained specialist therapist All of these factor lead to a greater waiting time
41
What is flooding?
Immediate exposure to the phobic stimulus Longer but fewer sessions
42
What are the advantages of flooding?
Deals with the cause Wolpe-Flooded a girls car phobia successfully by driving her around for hours
43
What are the disadvantages of flooding?
Difficult to access Wolpe-Found stress from flooding can put you in hospital Flooding isn't suitable for vulnerable people
44
What is OCD?
OCD is an anxiety related condition Have obsessional thoughts, repetitive compulsions
45
What is the behavioural characteristics of OCD?
Avoidance of situations that trigger obsessive thoughts Repetitive behaviours to reduce anxiety
46
What is the cognitive characteristics of OCD?
Obsessive, irrational thought Awareness that thoughts are irrational
47
What are the emotional characteristics of OCD?
Unpleasant emotions Depression Irrational guilt
48
How does statistical infrequency explain OCD?
Top/bottom 2% is considered abnormal
49
How does deviation from social norms explain OCD?
Its not normal to do some of these compulsions so falls into deviation
50
How does failure to function explain OCD?
Cannot preform daily task due to the compulsions and irrational thoughts
51
How does deviation from ideal mental health explain OCD?
Low self-esteem can stop individuals from meeting ideal mental health
52
What is the biological explanation of OCD?
Genes are involved in individuals vulnerability to OCD, OCD is quite common in families
53
How do genes cause OCD?
Mutated receptor cells leads to inefficient serotonin transmission
54
Is OCD just down to one gene?
No, OCD is polygenic - this means that several candidate genes contribute to the development of the condition
55
What study supports OCD being polygenic?
Taylor
56
How did Taylor support OCD being polygenic?
In a meta-analysis Taylor found that up to 230 genes may be involved in developing OCD
57
What is a supporting study of OCD being genetic?
Lewis, 37% of parents of participants had OCD but also 21% had siblings with OCD Suggests OCD runs in families
58
How does Nestadt support genetic explanation of OCD?
Twin study 68% concordance rate with MZ twins 31% concordance rate with DZ twins
59
What are the strengths of a genetic explanation of OCD?
Practical applications - SSRIS increase serotonin uptake Lewis supporting Nestadt supporting
60
What are the weaknesses of a genetic explanation of OCD?
Evidence from twin studies don't show 100% concordance SLT - OCD may develop due to modelling, explain family patterns Humanism - we have free will and OCD patients can simply change their behaviour
61
What is the neural explanations of OCD?
Abnormal levels of neurotransmitters - dopamine Abnormal brain structure
62
How can damage to lateral frontal lobes cause OCD?
Can lead to irrational decisions
63
What are the advantages of the neural explanations of OCD?
SSRIS - Increase serotonin levels OCD patients and their families had structural abnormalities
64
What are the disadvantages of the neural explanations of OCD?
Poor explanatory power - Whether OCD causes brain damage vies versa SLT - OCD may be learnt via modelling
65
How does drug therapy treat OCD?
Aim to increase levels of serotonin Blocks re-uptake receptors Serotonin continues to be active for longer
66
What are the advantages of drug therapy on OCD?
Soomro - Found SSRIs are significantly more effective than placebos Prescription fee is cheaper than a psychologist People are not on a long waiting list for treatment
67
What are the disadvantages of drug therapy on OCD?
Leads to other health problems - insomnia etc Treats symptoms rather than dealing with the cause of OCD Tolerance increases may need to up the dosage
68

Destroys links between brain structures
69
What are the behavioural characteristics of depression?
Shift in activity level Change in appetite Aggression
70
What are the cognitive characteristics of depression?

71
What are the emotional characteristics of depression?

72
Who explains is in the cognitive explanation of depression?
Beck Ellis

75
What is Ellis's ABC model of dperession?
Depression is a result of irrational thought A - Activating event B - Beliefs C - Consequences
76
What are the advantages of the cognitive explanation of Depression?
Practical applications - CBT and REBT Supporting Studies - O'Hara & March & Boury
77
What did O'Hara claim?
Meta analysis of risk factors for post-partum depression Cognitive vulnerability were predictors of depressive symptoms
78
What did March find?
Different treatments of depression CBT - 81% effective Anti-depressants - 81% effective Mixed group - 86% effective
79
What did Boury find?
Found that patients with depression are more likely to interpret things negatively
80
What are the disadvantages of the cognitive explanation of depression?
Cognitive is only correlational, don't know is depression causes negative thoughts or vice versa Ellis - Not everyone experiences an active event Biological - faulty genetics etc
81
What are the strengths of CBT?
March Can be used to on a range of patients Can be used in different ways - group, online, one-to-one
82
What are the weaknesses of CBT?
May not work on severe patients - lack of motivation Rosenzweig - relationship between patient and therapist is more important than techniques Ignores social circumstances - domestic violence
