Psychopathology Flashcards
What are the 4 definitions of abnormality?
- Statistical infrequency
- Deviation from the norm
- Failure to function adequately
- Deviation from ideal mental health
What is statistical infrequency?
Where abnormality is defined as those behaviours that are extremely rare. For example, any behaviour found in very few people is considered to be abnormal. It is usually measured using a bell shaped curve or a distribution graph. We usually define people at either end of the graph as abnormal as this means they are more than 2 standard deviations away from the norm and so only represent 2% of the population.
Why should duration and frequency be considered when looking at statistical infrequency?
Because traits like hearing voices would be considered more extreme if it happened every single day.
What is the double evaluation about abnormal behaviours actually being desirable and then cultural differences?
The main issue is that there are many abnormal behaviours that are actually quite desirable.
For example, very few people have an IQ over 150 so it is considered to be abnormal. However, this trait is actually desirable and does not lead individuals to need any additional help. Equally, there are many undesirable behaviours that are considered to be ‘normal’. For example, depression is fairly common amongst the population which means it is considered to be within 2 standard deviations from the norm. This means that it can be overlooked when individuals with depression do actually require additional help and to be treated.
Therefore, using statistical infrequency to define abnormality means that we are unable to distinguish between desirable and undesirable behaviours.
Furthermore, behaviours that are considered to be ‘abnormal’ in some cultures may be an important part and even a desired characteristic in other cultures. For example, hearing voices is a symptom of schizophrenia and so it is considered abnormal in western cultures and a sign of poor mental health. However, in African cultures, this trait is very normal and even praised due to religious beliefs.
Therefore, this definition of abnormality should not be equally applied to all cultures and culturally relative considerations should be made instead.
What is the evaluation about statistical infrequency being sometimes appropriate to use?
In some situations, it is appropriate to use statistical criterion to define abnormality.
For example, intellectual disability disorder is defined in terms of normal distribution using standard deviation to establish a ‘cut-off’ point for abnormality. Any individual with and IQ more than 2 standard deviations away from the mean, is considered to have a mental disorder. However, a diagnosis is only made in conjunction with failure to function adequately.
Therefore, this suggests that statistical infrequency is only used as one of a number of tools.
What is the definition of failure to function adequately?
It is where individuals are judged on their ability to go about their everyday lives. If they cannot do this and they are also experiencing distress (or others are distressed by their behaviour) then it is considered a sign of abnormality.
Who proposed characteristics of someone who is not functioning adequately?
And what are 4 examples?
Rosenham and Seligman 1989.
1. Maladaptive behaviour = where an individuals behaviour goes against their long term goals.
2. Observer discomfort= when the individuals behaviour causes distress to those around them by breaking the rules of societal expectations.
3. Irrationality= when it is difficult to understand the motivations behind someone’s unpredictable behaviour.
4. Personal anguish = where an individual is suffering with distress and anxiety.
What is the evaluation about who makes the judgment of functioning adequately?
Who decides what is meant by failure to function adequately?
It may be that the individuals themselves can recognise that something is not quite right and that their behaviour has become undesirable and is causing them distress so they seek help. On the other hand, some individuals may be content with their situation and/or may be unaware they are not coping. In this case, others around them may be made to feel uncomfortable by their behaviour and so deem it to be abnormal. For example, some schizophrenics may be potentially dangerous but a symptom of schizophrenia is that they do not believe anything is wrong with them. A real life example of this is Peter Sutcliffe the ‘Yorkshire Ripper’.
Therefore, the limitation of this definition of abnormality is that the judgment depends on who is making it, meaning that it can be subjective.
What is the evaluation about some behaviours actually being functional in failure to function adequately?
Another limitation is that some behaviours which are apparently ‘dysfunctional’ can actually be adaptive and functional for some people.
For example, some mental disorders like eating disorders and depression can manifest in ways which draw extra attention to those individuals. However, this attention can be adaptive as it can help them recognise a problem, get the help they need and find the root cause of the behaviours. These unusual behaviours may be used as coping mechanisms by those who are going through particularly difficult times in their lives. Additionally, transvestitism is considered a mental disorder, however those individuals probably regard it as being perfectly functional for them.
Therefore, failure to distinguish between functional and dysfunctional behaviours may mean that this definition is incomplete.
What is the evaluation about WHODAS in failure to function?
It should be noted that on the positive side, this definition can be a useful means to judge abnormality.
For example, the DSM includes an assessment of ability to function called WHODAS (world health organisation disability assessment). It involves individuals rating items including things like ‘can dress self’ and ‘can prepare meals’ on a scale of 1 to 5 with a final score out of 180. Listing behaviours and rating them on a scale provides a quantitative measurement of functioning meaning an objective judgment can be made as to whether someone requires treatment. Furthermore, this assessment allows the subjective experience of the patients to be recognised as they give a rating that they identify with the most.
This definition of abnormality therefore, has a certain sensitivity and practicality to it.
What is the definition of deviation from ideal mental health?
Abnormality is defined in terms of mental health, behaviours that are associated with competence and happiness. Ideal mental health would include a positive attitude towards the self, resistance to stress and an accurate representation of reality.
Who proposed the 6 criteria for ideal mental health and what are the 3 points about her?
Marie Jahoda 1958
- Pointed out that physical illness is defined by the absence of signs of physical health like not having a normal temperature or blood pressure, and she suggested that we also apply this to mental illness.
- She reviewed things that had been said about good mental health and used them to devise 6 characteristics that enable people to be happy and behave competently.
- Her definition is from a humanistic perspective as it looks at how we can improve ourselves and become better people rather than on dysfunctional behaviours.
What are Marie Jahoda’s 6 criteria for ideal mental health?
- Self attitude= Having a high self esteem and strong sense of identity.
- Personal growth and self actualisation= The extent to which a person develops their full capabilities.
- Integration= Being able to cope with stressful situations.
- Autonomy= Being independent and self regulating.
- Having an accurate perception of reality.
- Mastery of environment= The ability to ‘love’, function at work and in interpersonal relationships, adapt to new situations, and solve problems.
What is the evaluation about Jahoda’s criteria being positive and humanistic?
One strength of Jahoda’s definition is that it takes a positive and holistic view.
Firstly, the definition focuses on positive and desirable behaviours rather than negative and undesirable traits. Jahoda’s criteria has real world applications. For example, it can be used as a basis for therapy and treatments with emphasis on the self as a whole and working towards goals such as self actualisation and integration. Her ideas were also used by Rogers 1959, who influenced counselling to take a more client centred approach.
Therefore, the strengths of this definition can be seen within its influences on humanistic approaches and the positive psychology movement.
What is the evaluation about everyone being abnormal according to Jahoda?
One of the major criticisms of this definition is that according to the ideal mental health criteria, most of us would be abnormal.
It would be very difficult to achieve this criteria all the time. And according to Jahoda, most people would be diagnosed as abnormal as it is so unrealistic. For example, we all experience negativity and stress at times, especially if grieving a loved one for example. However, this definition suggests that these people would all be classified as abnormal irrespective of the circumstances. Furthermore, this criteria seems quite difficult to measure. For example, how easy would it be to assess capacity for personal growth?
Therefore, due to the high standards set by this criteria, the number of characteristics needed to be absent for a diagnosis should be questioned.
What is the definition of phobias?
A group of mental disorders characterised by high levels of extreme anxiety produce in response to a stimulus or group of stimuli. They are instances of irrational fears that produce conscious avoidance of the feared object or situation.
What are three examples of phobias?
- Agoraphobia= the fear of being trapped in a public space with no escape. Common in middle age.
- Social phobias= anxiety related to social situations like speaking to a new group or people or going to a party.
- Specific phobias= Phobias of specific objects like spiders or snake, or of specific situations like heights or the dark.
All phobias are more common in women.
What are the behavioral characteristics of phobias (3)?
- Avoidance= Physically avoiding phobic objects. E.g leaving the room that a spider is in.
- Panic= Uncontrollable physical response usually when the feared object or situation appears suddenly. E.g screaming or hyperventilating.
- Failure to function= Avoidance interfering with a person’s normal routine, work and relationships. This distinguishes phobias from less severe everyday fears.
What are the emotional characteristics of phobias? (2)
- Fear= The intense emotional state linked with the fight or flight response which causes the body to be unpleasantly alert for long and persistent periods. Likely to be excessive and uncontrollable.
- Anxiety= An uncomfortably high and persistent state of arousal making it difficult to relax. Usually heightened when individual is likely to encounter phobia.
These are both usually out of proportion to actual danger posed.
What are the cognitive characteristics of phobias? (3)
- Irrational beliefs= Negative mental processes that include exaggerated beliefs about the harm that the phobic object could cause them. E.g a person with aerophobia would not feel better knowing flying is the safest form of transport.
- Reduced cognitive capacity= Where people with phobias cannot concentrate on everyday tasks like work due to the excessive attentional focus on phobic objects and the constant fear about the danger they are in.
- Cognitive distortions
What is the behavioural explanation of phobias and who proposed it?
The 2 process model proposed by Mowrer 1947.
The 2 process model says that phobias are acquired through classical conditioning (learning through association) and are maintained through operant conditioning (learning through consequences).
Who is the key study for the acquisition of a phobia?
Watson and Rayner 1920
‘Little Albert’.
- They used an 11 month old infant who had no reaction to white furry objects to begin with.
UCS (banging a metal bar with a hammer behind his head to startle him)—> UCR (crying)
NS (rat) + UCS (banging bar every time he reached for the rat) ——> UCR (crying)
- They repeated this pairing 3 times and then again a week later.
CS (rat)———> CR (crying)
- They realised that the conditioned fear response could be generalised to other white furry objects.
- They also realised that the fear did not disappear overtime.
How does operant conditioning lead to the maintenance of phobias?
Classical conditioning explains the acquisition, but can not explain why people continue to feel fearful and even avoid the phobic object.
Operant conditioning says: the likelihood of the behaviour being repeated is increased if the outcome is rewarding.
In terms of phobias, people will avoid the feared object or situation which reduces anxiety.
This reduced fear and anxiety is a pleasant sensation to negatively reinforces the belief that they should avoid the feared object. This strengthens the phobia and makes it more likely that they will avoid it again in the future.
What is the evaluation about biological preparedness for phobias?
The fact that phobias do not always develop after a traumatic experience may be explained in terms of biological preparedness.
For example, Martin Seligman 1970 argued that animals, including humans are genetically programmed to rapidly learn associations between potentially life threatening stimuli and fear. These stimuli are known as ‘ancient fears’, things that would have been dangerous in our evolutionary past like heights, spiders and the dark. It would have been adaptive to rapidly learn to avoid such stimuli. This may explain why we are less likely to develop phobias of more modern objects such as toasters and cars which pose much more danger than a spider. But these objects were not a danger in our evolutionary history so we don’t.
Therefore, this suggests that the behavioural approach cannot fully explain all phobias.
