Q

What is statistical infrequency, with example

A

Defining abnormality in terms of number of times it has been observed.
Behaviour that is rarely seen is abnormal.
e.g, average IQ is between 85 and 115. 2% of people score below 70. This 2% would be seen as intellectually abnormal, and be diagnosed with intellectual disability disorder.

Q

What are two negatives of statistical infrequency

A

Abnormal does not always mean negative
IQ scores above 130 are just as rare as below 70, but this is not regarded as undesirable or requiring treatment.

Social stigma
Abnormality through not fitting with the majority could lead to social consequences for the patient.
This means labelling someone as abnormal just because they are statistically unusual

Q

What is a strength of deviation from social norms

A

Flexibility
It is flexible dependent on situation and age.

Q

What is a limitation of deviation from social norms

A

Cultural relativity
Norms vary across cultures.
Hearing voices is acceptable in some cultures, but in the Western world, this is seen as abnormality.
This means it is difficult to judge deviation from social norms across different contexts.

Q

What are 2 advantages of failure to function

A

Behaviour is easily observable
Failure to function adequately can be seen by others around the individual because they may not get out of bed on a morning.
This means that problems can be picked up by others and they can help intervene.

Consideration of how the individual feels
This definition is focused on the individual and how they are managing in everyday life from their perspective.
If someone feels as though they are struggling they will be deemed abnormal and get help.

Q

What is a limitation of failure to function adequately

A

Failure to function may not be a sign of abnormality
In some cases, failure to function is a normal response, for example in bereavement.
It is unfair to give someone a label for reacting normally to difficult circumstances

Q

What are 2 strengths of ideal mental health

A

Comprehensive
Includes a range of criteria for mental health, covering most reasons why someone may need help.
This gives professionals the opportunity to have meaningful discussions with patients on their mental health.

Clear goals
Gives a clear checklist for patients to try to reach in order to have an ideal mental health.
This can help treatment and recovery plans for those with mental disorders

Q

What are 2 limitations of ideal mental health

A

Cultural relativity
Differing value placed on different criteria across different countries.
e.g, in Germany, there is high value placed on independence, while low value placed in Italy.
This means it is difficult to generalise ideal mental health to all people.

Unrealistic standards
Very few people will tick all of Jahoda’s criteria, and almost nobody will maintain them for long.
This makes majority of the population abnormal, which is paradoxical as then that would be normal.

What are emotional characteristics of depression
Lowered mood Anger Lowered self-esteem
26
What is OCD
An anxiety disorder and is characterised by experiencing persistent and intrusive thoughts which occur as obsessions, compulsions or sometimes both.
27
What are behavioural characteristics of OCD
Repetitive compulsions Compulsions reduce anxiety Avoidance of anxiety triggering situations
28
What are emotional characteristics of OCD
Anxiety and distress Depression Guilt and disgust
29
What are cognitive characteristics of OCD
Obsessive thoughts Cognitive coping strategies, like meditation Poor concentration Focus on negatives Absolutist thinking
30
What does behaviourist explanation for phobias believe
That phobias are learned through classical conditioning and maintained by operant conditioning (Mowrer 1960)
31
What is the two process model
Classical and operant conditioning working together to learn and affirm a phobia
32
What is a research support for behavioural explanation for phobias
Watson and Rayner (1920) 'Little Albert' study
33
What was Watson and Rayners study called
'Little Albert' study
34
What was the process of Watson and Rayners study
Whenever Albert played with a white rat, a loud noise was made close to his ear (UCS), creating a fear response (UCR). Rat (NS) did not create a fear response until the noise and rat were paired together several times. Albert showed a fear response (CS) every time he came into contact with the rat (now a CS) Albert also had generalised fear to other white furry objects
35
How does operant conditioning maintain phobias
Avoiding situations with the stimulus negatively reinforces the phobia, e.g a person scared of lifts takes the stairs, which relieves anxiety.
36
What are 2 strengths of the two-process model/behavioural approach to explaining phobias
RWA Idea that phobias are maintained by avoidance helps to explain why exposure therapies work, as it removes the negative conditioning used to maintain phobias. Evidence linking phobias to bad experiences De Jognh et al (2006) found 73% of dental phobics had experienced a trauma to do with dentistry. This suggests that NS of dentistry with the UCS of pain lead to the phobia.
37
What are 2 limitations of the behavioural approach to explain phobias
Unable to explain cognitive aspects of phobias Behavioural explanation is geared towards explaining behaviour, such as avoidance, while ignoring the significant cognitive components like irrational beliefs. Not all phobias are learnt Many people have a phobia of snakes in places where very very few people have any experiences with snakes, e.g UK. Additionally, not all frightening experiences lead to phobias. This means behavioural explanation cannot explain all phobias.
38
What are the two behavioural approaches to treating phobias
Systematic desensitisation (SD) Flooding
39
What is systematic desensitisation based on
Classical conditioning
40
What does systematic desensitisation therapy aim to do
Gradually reduce anxiety through counterconditioning
41
What is the process of systematic desensitisation
Therapist and client design an anxiety hierarchy. Client is taught relaxation techniques like deep breathing. Works through the anxiety hierarchy with the following process for each step. Phobia is learned and becomes the conditioned stimulus (CS) The patient has the CS paired with relaxation, and this feeling becomes the new CR. Relies on reciprocal inhibition.
42
What is reciprocal inhibition
The idea that it is not possible to be afraid and relaxed at the same time, so one emotion prevents the other.
43
What is the anxiety hierarchy
Fearful stimuli arranged in order from least to most frightening, e.g a small spider up to a tarantula
44
What is flooding
Exposing a person with a phobia to the phobic object with no gradual build up.
45
What is an example of flooding
Person with arachnophobia having a tarantula crawl over their hand until they can relax fully.
46
What is a strength of systematic desensitisation (SD)
Evidence of effectiveness Gilroy et al (2003) Followed 42 people who went through SD for arachnophobia. On follow up, those that had SD were less fearful than a control group.
47
What is a limitation of systematic desensitisation
Time consuming Takes a long time to complete all stages, from anxiety hierarchy, breathing techniques and working up the hierarchy. This then means the therapy is more expensive, making it less accessible to lower income patients.
48
What is a strength of flooding
Cost effective and quick Flooding can work in just 1-3 hours, meaning patients do not need to pay as much or donate as much time in comparison to other treatments like SD.
49
What is a limitation of flooding
Can be traumatic Schumacher et al (2015) found that both participants and therapists rated flooding as more stressful than SD. Thus, there can be ethical concerns about willingly causing stress (which can be offset with informed consent). This suggests that therapist may avoid using this treatment.
50
What does the cognitive approach believe to explain depression
Depression is due to irrational thoughts from maladaptive internal mental processes
51
What did Beck (1957) theorise
Negative triads
52
What does Beck believe causes depression
That some people were more prone to depression because of faulty information processing. Negative self schema, which interprets all information about themselves in a bad way.
53
What are the three negative schemas of the negative triad
The self - feeling inadequate or unworthy The world - thinking people are always hostile The future - 'things will always turn out badly'
54
What is Beck's negative triad and when is it developed
Three schemas with an automatic negative bias Developed in childhood to give persistent biases in adulthood, leading to cognitive distortions
55
What are 2 cognitive distortions in depression
Overgeneralisation - the belief that one negative experience causes assumption that same thing will always happen Selective abstraction - mentally filtering out positive experiences and focusing on the negative. e.g, posting on social media and getting lots of positive attention, but focusing on the one negative comment.
56
Who theorised the ABC model
Ellis
57
What does ABC stand for in ABC model
Activating event - can be anything that happens to someone Belief - people without depression have rational beliefs about A, depressed people have irrational beliefs about A. Consequence - rational beliefs lead to positive consequences, irrational leads to negative
58
What is an example of a rational ABC model
A - Break up B - Weren't right for each other, want different things, etc C - Look for new healthy relationship
59
What is an example of an irrational ABC model
A - Break up B - Fundamentally unlovable, never be able to find someone C - Avoid relationships altogether, or get into a new unhealthy one
60
What is mustabatory thinking
Irrational thinking where person does not accept we don't live in a perfect world.
61
What are the three musts in mustabatory thinking
I must do well You must treat me well The world must be easy
62
What is a research support of Becks model
Clark and Beck (1999) Concluded negative vulnerabilities like negative schema are more common in depressed people. Shows there is an association between cognitive vulnerability and depression
63
What is a second strength of Becks model (not research support)
RWA Screening for depression by assessing cognitive vulnerability Understanding this cognitive vulnerability can allow those with high risk of depression to be monitored, and can be applied to CBT to alter these cognitions.
64
What is a strength of Ellis' model
RWA in REBT therapy Rational emotive behaviour therapy can change negative beliefs and relieve symptoms of depression.
65
What are two limitations of Ellis' model
Only explains reactive depression In many cases, depression has no obvious triggers, which is endogenous depression. Places blame on patient Can further depression as patient may feel responsible for their own condition
66
What is reactive depression
A form of depression triggered by activating events.
67
What is endogenous depression
Depression with no clear root trigger
68
What is CBT
Cognitive behaviour therapy Most common psychological treatment for depression Cognitive - challenge irrational thoughts Behaviour - change behaviour so it is more effective
69
What is the process of CBT
Challenge negative thoughts Client encouraged to test reality of irrational beliefs through 'homework' Taught mindful meditation to combat depression
70
What is REBT
Ellis' therapy Rational emotive behaviour therapy Extends ABC model to 'ABCDE' model by adding dispute and effect
71
What is the two parts to REBT therapy
Challenge irrational thoughts: - Empirical argument; disputing evidence to support the irrational belief - Logical argument; disputing whether negative thought actually follows the facts Behavioural activation: When individuals are depressed they tend to avoid difficult situations. Behavioural activation helps to gradually reduce avoidance and isolation, and increase engagement in activities to improve mood
72
What is a strength of CBT
March et al (2007) Evidence of effectiveness Compared CBT against antidepressants and a combination of CBT and antidepressants against a control group. After 36 weeks, 81% of CBT group, 81% of antidepressant group and 86% of combination group were significantly improved. This makes CBT a good choice for first treatment of depression
73
What is 2 limitations of CBT
High relapse rates Ali et al (2017) Assessed depression for one year following a CBT course 42% relapsed in 6 months and 53% relapsed within a year. This means CBT may not be a permanent fix Time and money CBT requires patient to give up at least an hour a week for the duration of the course, and pay usually a large sum of money (unless NHS treatment is taken). This means it may not be possible for everybody.
74
What is the two biological explanations for OCD
Genetic explanation Neural explanation
75
What is the genetic explanation for OCD
Believing that OCD is inherited from our parents through 'candidate genes' that may cause the illness
76
What are the two candidate genes for OCD
COMT gene SERT gene
77
What is the COMT gene
Associated with production and regulation of dopamine.
78
What is different about COMT gene in OCD sufferers
Overactive, producing higher levels of dopamine.
79
What is the SERT gene
Associated with transport of serotonin
80
What is different about SERT gene in OCD patients
Causes lower levels of serotonin
81
What is the neural explanation for OCD
Focus on neurotransmitters and brain structures
82
What neurotransmitters are implicated in OCD
Abnormal levels of dopamine and serotonin
83
What is serotonins function
To regulate mood
84
What levels are dopamine/serotonin at to influence OCD
Serotonin - very low Dopamine - very high
85
How can brain structures influence OCD
Damaged or faulty frontal lobes
86
What is frontal lobe responsible for
Decision making and logical thinking
87
What is a strength of genetic explanation for OCD
Twin studies Nestadt et al (2010) Found concordance rates of 68% in identical twins (MZ) and 31% in non identical twins (DZ) This means people who are genetically similar are more likely to share OCD, supporting idea of genetic vulnerability.
88
What is a limitation of genetic explanation for OCD
Does not account for environmental risk factors Cromer et al (2007) found over 50% of OCD sufferers experienced a traumatic event. This means genetic vulnerability only offers a partial explanation for OCD.
89
What is a strength of neural explanation
Antidepressant research Antidepressants that are based on serotonin (SSRIs) reduce OCD symptoms. This suggests that neurochemical factors, specifically serotonin, is a factor in OCD
90
What is a limitation of neural explanation
Correlation and causality While we can see that brain structures and neurochemical levels are altered in patients with OCD, we cannot know if these changes are due to OCD, or were the cause of it.
91
What does SSRI stand for
Selective serotonin reuptake inhibitors
92
What do SSRIs do
Prevent reabsorption and breakdown of serotonin in the brain. This increases its levels in the synapse and so serotonin continues to stimulate. This compensates for the decrease of serotonin causing OCD
93
What are drug treatments (SSRIs) usually combined with when treating OCD
CBT
94
What are alternatives to SSRIs
Tricyclics SNRIs
95
What are two strengths of drug therapy
Effectiveness Soomro et al (2009) Reviewed 17 studies of SSRIs for treatment of OCD. All 17 studies showed better outcomes following SSRIs than placebos. Typically symptoms were reduced by around 70%. This shows drugs are highly effective and can be used widely Low money and time In general cheaper than psychological treatments, meaning it is good value for the NHS and patients. SSRIs also do not disrupt patients lives as they don't require time and energy like therapy. This means both doctors and patients may prefer drug therapy.
96
What is a limitation of drug therapy
Side effects A minority of people experience no benefit from SSRIs, and have side effects like indigestion and blurred vision, though these are usually temporary. This means that it can reduce quality of life, reducing patients will to carry on with the treatment.
