Q

How does classical conditioning induce a phobia?

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

Q

What is depression?

A

A disorder that includes disabling moods

28
Q

Behavioural characteristics of depression

A

Activity levels
Disruptions to sleep and eating
Aggression and self harm.

29
Q

Cognitive characteristics of depression

A

Poor concentration
Attending and dwelling on negative Absolutist thinking

30
Q

Emotional characteristics of depression

A

Lowered mood
Anger
Lowered self esteem

31
Q

What are the two explanations of depression?

A

Becks theory of depression
Ellis’s ABC model

32
Q

What are the 3 elements of beck theory of depression

A

negative self schemas
cognitive biases
the cognitive negative triad

33
Q

What does the cognitive triad consist of?

A

The self
The world
The future

34
Q

What is a strength of Becks cognitive theory?

A

Cohen concluded that assessing cognitive vulnerability allows us to screen young people, identifying most at risk of developing depression for earlier intervention.

35
Q

What is a weakness of Becks cognitive theory?

A

Ignores biological factors and can be considered a reductionist way of explaining depression

36
Q

What does Ellis ABC model of depression stand for?

A

A = activating events
B= beliefs
C= consequences

37
Q

What is a strength of Ellis ABC model?

A

therapies such as REBT

38
Q

What is a weakness of Ellis ABC model

A

Only explains reactive depression not endogenous depression

39
Q

What are the two treatments for depression

A

CBT - Beck
REBT - Ellis

40
Q

What does CBT stand for?

A

Cognitive behavioural therapy

41
Q

What does CBT involve?

A

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
Q

A strength and weakness of CBT

A

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
Q

What does REBT stand for?

A

Rational Emotive Behavioural Therapy

44
Q

What does REBT include?

A

ABCDE - Disputing irrational beliefs, noticing the Effects of the dispute.
Patients do homework tasks to relate to their disputed thoughts

45
Q

What does OCD stand for?

A

Obsessive Compulsive Disorder

46
Q

Behavioural characteristics of OCD

A

Avoidance
Compulsions are repetitive
Compulsions reduce anxiety

47
Q

Emotional characteristics of OCD

A

Anxiety and distress
Disgust
Accompanying depression

48
Q

Cognitive characteristics of OCD

A

Obsessive thoughts
cognitive coping strategies
insight into excessive anxiety

49
Q

What genes are involved in the development of OCD

A

SERT gene (serotonin regulatory gene)
COMT gene (regulating the production of dopamine)

50
Q

Cognitive characteristics of OCD

A

Obsessive thoughts
Cognitive coping strategies
Insights into excessive anxiety

51
Q

As there are multiple genes involved in OCD what does this mean?

A

OCD is polygenic

52
Q

How does the SERT gene affect OCD

A

If the SERT gene is faulty it causes transportation issues and so lower levels of serotonin that impacts OCD like symptoms

53
Q

How does the COMT gene affect OCD

A

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
Q

What is the diathesis stress model?

A

That environmental stressors trigger certain genes to influence OCD.

55
Q

Strengths of the genetic explanation?

A

Nestadt found that 68% of MZ twins had OCD compared to 31% of DZ twins

56
Q

Weaknesses of genetic explanation of OCD

A

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
Q

What areas of the brain are involved in the neural explanations for OCD

A

Caudate nucleus
Orbital frontal cortex (OFC)

58
Q

What is the neural explanation for OCD?

A

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
Q

Strengths of neural explanation for OCD

A

Development of treatments such as SSRIs

60
Q

Weaknesses of neural explanation for OCD

A

All evidence for neural explanations are simply correlational which has no causation between neurochemicals and OCD

61
Q

What treatment is used for OCD

A

SSRIs (Selective serotonin reuptake inhibitors)

62
Q

How do SSRIs work?

A

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
Q

Strength of SSRIs

A

Soomro - symptoms reduce 70% when using SSRIs

64
Q

Weakness of SSRIs

A

Side effects

65
Q

What other treatments other than SSRIs can be used to treat OCD

A

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)
