Q

What is a common weakness of failure to function adequately, deviation from social norms and deviation from ideal mental health?

A

They are all ethnocentric as they differ culture to culture and do not apply to all cultures

Q

How does classical conditioning induce a phobia?

A

Pairing a neutral stimulus (white rat) with an unconditioned stimulus (loud noise) that after enough pairings creates a conditioned response of fear

Q

How does operant conditioning maintain a phobia?

A

Through negatively reinforcing the phobia. Avoiding the stimulus and removing anxiety acts as a reward so negatively reinforces behaviour

25
What does systematic desensitisation work off of?
Reciprocal inhibition, you cannot be relaxed and stressed at the same time
26
What does systematic desensitisation include
Fear Hierarchy Pairing Relaxation techniques with fear hierarchy Rating fear on a scale of 1-100 Moving up stages once anxiety is low
27
What is depression?
A disorder that includes disabling moods
28
Behavioural characteristics of depression
Activity levels Disruptions to sleep and eating Aggression and self harm.
29
Cognitive characteristics of depression
Poor concentration Attending and dwelling on negative Absolutist thinking
30
Emotional characteristics of depression
Lowered mood Anger Lowered self esteem
31
What are the two explanations of depression?
Becks theory of depression Ellis's ABC model
32
What are the 3 elements of beck theory of depression
negative self schemas cognitive biases the cognitive negative triad
33
What does the cognitive triad consist of?
The self The world The future
34
What is a strength of Becks cognitive theory?
Cohen concluded that assessing cognitive vulnerability allows us to screen young people, identifying most at risk of developing depression for earlier intervention.
35
What is a weakness of Becks cognitive theory?
Ignores biological factors and can be considered a reductionist way of explaining depression
36
What does Ellis ABC model of depression stand for?
A = activating events B= beliefs C= consequences
37
What is a strength of Ellis ABC model?
therapies such as REBT
38
What is a weakness of Ellis ABC model
Only explains reactive depression not endogenous depression
39
What are the two treatments for depression
CBT - Beck REBT - Ellis
40
What does CBT stand for?
Cognitive behavioural therapy
41
What does CBT involve?
Changing irrational thoughts and beliefs to positive ones Involves the client as a scientist to investigate their own thoughts Set homework to change their behaviour to match thoughts
42
A strength and weakness of CBT
Strength = Cost effect and CBT is better than no treatment at all (Robinson) Weakness= CBT seems to lack effectiveness for severe cases and for those with learning disabilities.
43
What does REBT stand for?
Rational Emotive Behavioural Therapy
44
What does REBT include?
ABCDE - Disputing irrational beliefs, noticing the Effects of the dispute. Patients do homework tasks to relate to their disputed thoughts
45
What does OCD stand for?
Obsessive Compulsive Disorder
46
Behavioural characteristics of OCD
Avoidance Compulsions are repetitive Compulsions reduce anxiety
47
Emotional characteristics of OCD
Anxiety and distress Disgust Accompanying depression
48
Cognitive characteristics of OCD
Obsessive thoughts cognitive coping strategies insight into excessive anxiety
49
What genes are involved in the development of OCD
SERT gene (serotonin regulatory gene) COMT gene (regulating the production of dopamine)
50
Cognitive characteristics of OCD
Obsessive thoughts Cognitive coping strategies Insights into excessive anxiety
51
As there are multiple genes involved in OCD what does this mean?
OCD is polygenic
52
How does the SERT gene affect OCD
If the SERT gene is faulty it causes transportation issues and so lower levels of serotonin that impacts OCD like symptoms
53
How does the COMT gene affect OCD
this gene is responsible for the enzyme that breaks down dopamine and when there is a mutation it stops this process = higher levels of dopamine
54
What is the diathesis stress model?
That environmental stressors trigger certain genes to influence OCD.
55
Strengths of the genetic explanation?
Nestadt found that 68% of MZ twins had OCD compared to 31% of DZ twins
56
Weaknesses of genetic explanation of OCD
There are many environmental risks involved in OCD - Cromer found that half of his sample with OCD had gone through trauma in their past suggesting environmental factors affect OCD development rather than being truly genetic in nature.
57
What areas of the brain are involved in the neural explanations for OCD
Caudate nucleus Orbital frontal cortex (OFC)
58
What is the neural explanation for OCD?
The OFC sends a worry signal and the caudate nucleus switches this off. When the SERT and COMT gene are compromised they cause the OFC to send too many worry signals (too much dopamine) and the caudate nucleus cannot send turn it off (because of low levels of serotonin).
59
Strengths of neural explanation for OCD
Development of treatments such as SSRIs
60
Weaknesses of neural explanation for OCD
All evidence for neural explanations are simply correlational which has no causation between neurochemicals and OCD
61
What treatment is used for OCD
SSRIs (Selective serotonin reuptake inhibitors)
62
How do SSRIs work?
They block the reuptake of serotonin on the pre synaptic cell allowing the serotonin to bind to receptors on the post synaptic cell. This usually leads to the chemical message being passed on to help the caudate nucleus switch off the worry circuit.
63
Strength of SSRIs
Soomro - symptoms reduce 70% when using SSRIs
64
Weakness of SSRIs
Side effects
65
What other treatments other than SSRIs can be used to treat OCD
Tricyclics (blocks the transport mechanism that reabsorbs serotonin) and benzodiazepines that slows down activity in the central nervous system by enhancing GABA activity (GABA produces a calming affect)
