PSYCHOPATHOLOGY Flashcards
What is psychopathology?
The scientific study of psychological disorders.
What does the deviation from social norms explanation tell us about abnormality?
Someone is classed as abnormal when they violate societal norms (explicit or implicit).
Give some examples of deviation from social norms
- Showing inappropriate affect may be a symptom of schizophrenia
- Paedophilia and voyeurism
- Psychopathy
Give one strength of the deviation from social norms explanation for abnormality (desirability)
The definition factors in the desirability of the behaviour, which is ignored by other definitions of abnormality. This means that behaviours that are numerically rare can be socially acceptable and therefore not abnormal. For instance, being a genius is statistically abnormal but we wouldn’t want to suggest that it is an abnormal behaviour in terms of psychopathology. This suggests that social norms can be a more useful definition of abnormality than using statistical norms.
Give one limitation of the deviation from social norms explanation of abnormality (times)
Social norms vary as times change. What is socially acceptable now may not have been 50 years ago e.g., homosexuality. This suggests that the definition may lack temporal validity unless changing social norms are taken into account. Therefore, the definition should only be used with caution, and perhaps in combination with a more objective definition of abnormality in order to prevent defining people as abnormal simply because the definition has taken into account changing social norms.
Give one weakness of the deviation from social norms explanation of abnormality (cultural relativism)
The definition suffers from cultural relativism. Social norms are defined by culture. This means that a person from one cultural group may label someone from another culture as behaving abnormally according to their standards rather than the standards of the person behaving in that way e.g., hearing voices. This suggests that the definition may not be externally valid and so shouldn’t be applied outside the culture it was created in without caution. In particular, the definition creates problems for people from one culture living within another culture group as they may be abiding by their cultures social norms but be deviating from the social norms of the culture in which they now live. Therefore, psychologists must be sensitive to such cultural differences when defining abnormality.
What is statistical infrequency in terms of abnormality?
A person’s trait, thinking or behaviour would be considered an indication of abnormality if it was found to be numerically rare. Therefore, it relies on up-to-date statistics. This depends on normal distribution, and any individual who falls outside the ‘normal distribution’, so they occupy the extreme ends of a normal distribution curve are considered to be abnormal.
Give one weakness of the statistical infrequency explanation of abnormality (desirability)
There are many statistically rare behaviours that are desirable. For example, very people have an IQ over 150, but we would not want to suggest that having a high IQ is undesirable or abnormal. Therefore, using statistical infrequency to define abnormality means that we are unable to distinguish between desirable and undesirable behaviours. This suggests that the definition should never be used in isolation to make a diagnosis.
Give a weakness of the statistical infrequency definition of abnormality (cultural relativism)
An issue for the definition is that it is culturally relative. Behaviours that are statistically infrequent in one culture may be statistically more frequent in another. For example, one of the symptoms of schizophrenia is claiming to hear voices, but this experience is common in some cultures. This suggests that the definition may not be externally valid and so shouldn’t be applied outside the culture it was created in without caution. In particular, the definition creates problems for people from one culture living within another culture group as their behaviour may be common in their own culture, but statistically infrequent in the culture in which they are now living. Therefore, psychologists must be sensitive to such cultural differences when defining abnormality.
Give a strength of the statistical infrequency definition of abnormality (clinical assessment)
The definition can be useful as part of clinical assessment. For example, it has real-life application in the diagnosis of IDD. There is therefore a plave for statistical infrequency in thinking about normal and abnormal behavioural characteristics. One of the assessments of patients with mental disorders includes some kind of measurement of the severity of symptoms compared to statistical norms. This suggests that the definition is externally valid as it can be applied to usefully applied to different situations to aid in clinical assessments.
What is the failure to function adequately definition and what does it say about abnormality?
The definition sees individuals as abnormal when their behaviour suggests that they cannot cope with the demands of everyday living. Behaviour is considered abnormal when it is maladaptive, irrational or dangerous, which causes distress, leading to an inability to function properly e.g., disrupting the ability to work or conduct satisfying interpersonal relationships.
What does not functioning adequately cause?
- Distress/suffering for the individual
- Distress to others
Give a weakness for the failure to function adequately definition of abnormality (cultural relativism)
The definition suffers from cultural relativism. In some cultures, women are not expected to maintain a job, or people are expected to go without food for significant periods of time. Using the definition, such people would be classified as abnormal simply because their cultural norms differ from out own. This may explain why lower-class and non-white patients are more often classified as abnormal; their lifestyles are different from the dominant culture and this may lead to a judgement of failing to function adequately.
Give a weakness for the failure to function adequately definition of abnormality (subjective)
When deciding whether someone is failing to function adequately, someone has to judge whether a patient is distressed or distressing others. Some patients may say that they are distressed but may not be judged as suffering. There are methods for making such assessments as objective as possible. However, the principle remains that someone has the right to make this judgement.
Give a strength for the failure to function adequately definition of abnormality (subjective experience)
It attempts to include the subjective experience of the individual. It may not be an entirely satisfactory approach because it is difficult to assess distress, but the definition acknowledges that the experience of the patient is important. Therefore, the definition captures the experience of many who need help. This increases the validity of the explanation of abnormality compared to the other definitions e.g., statistical infrequency.
Who proposed the criteria for deviation from ideal mental health?
Jahoda
What does the deviation from ideal mental health definition suggest (overview)
This definition looks at the positives rather than the negatives - the idea of mental health rather than mental illness.
What are the 6 major criteria for optimal living proposed by Jahoda?
- Self attitudes
- Personal growth and self-actualisation
- Integration
- Autonomy
- Having an accurate perception of reality
- Mastery of the environment
Give one weakness of the deviation from ideal mental health definition of abnormality (difficulties in measuring)
The criteria are quite difficult to measure. For example, how easy is it to assess capacity for personal growth or environmental mastery? This means that this approach may be an interesting concept but not really useable when it comes to identifying abnormality because the criteria are too subjective to be applied consistently by psychologists. This could pose problems for psychologists using the definition as one may identify abnormality where another doesn’t. As such, patients who may benefit from treatment may not be given the opportunity to access it.
Give a weakness for the deviation from ideal mental health definition of abnormality (time)
Perceptions of reality change over time. Once seeing visions was a positive sign of religious commitment, whilst now it would be perceived as a sign of schizophrenia. This suggests that the definition may not be a valid way of identifying abnormality unless such changes are taken into account.
Give a strength of the deviation from ideal mental health definition of abnormality (comprehensive)
The definition is very comprehensive. It covers a broad range of criteria for mental health, and therefore most of the reasons why someone would seek help from mental health services or be referred for help. This suggests that the definition is a useful tool for thinking about mental health, even if it not the most useful for identifying abnormality.
What are the emotional characteristics of phobias?
- Anxiety
- Emotional responses are unreasonable
What are the behavioural characteristics of phobias?
- Panic
- Avoidance
- Endurance
What are the cognitive characterics of phobias?
- Selective attention to the soruce of the phobia
- Irrational beliefs
- Cognitive distortions
What does the behavioural approach emphasise about how phobias are learned?
Emphasises the role of learning in the acquisition of behaviour. It focuses on behaviour we can see, so it is geared towards explaining the behavioural characteristics of phobias, rather than the emotional and cognitive characteristics.
What did Mowrer propse?
The two-process model to explain phobias. This argues that phobias are acquired by classical conditioning, and then maintained because of operant conditioning.
How is a phobia acquired through the two-process model?
A phobia (conditioned response) is acquired through the association of something that we initially have no fear of (a neutral stimulus) with something that already triggers a fear response.
Define one trial learning
This can occur where the phobia is learned after only one pairing of the NS and UCS.
Go through the process of classical conditioning for acquiring phobias
Before conditioning:
- Neutral stimulus (dark) = No response
- Unconditioned stimulus (being mugged) = Unconditioned response (fear)
During conditioning:
- Neutral stimulus (dark) + Unconditioned stimulus (being mugged) = Unconditioned response (fear)
After conditioning:
- Conditioned stimulus (dark) = Conditioned response (fear)
How does operant conditioning suggest that we maintain a phobia?
Whenever we avoid a phobic stimulus, we successfully escape the fear and anxiety that we would have suffered if we had remained there. This reduction in fear reinforces the avoidance behaviour (via negative reinforcement) and so the phobia is maintained as avoidance is more likely to happen again in the future.
Give one piece of supporting evidence for the two-process model (Little Albert)
Watson and Rayner carried out a lab experiment with an 11 month old boy who lived in the hospital where his mother was a nurse. Albert was presented with various stimuli e.g., a white rat and rabbit, and showed no fear reaction to any stimuli. A fear reaction was then induced by striking a steel bar with a hammer behind his head, which made Albert cry. Then, when he reached to touch the rat, the bar and hammer were struck to frighten him. this supports the explanation of phobias, because Albert had a conditioned emotional response. This supports the validity of the theory as an explanation of phobias as some phobias do develop through learning processes.
Give a weakness for the two-process model of phobias (evolution)
Sometimes people develop a phobia and are not aware of having had a related bad experience e.g., phobias of snakes. Such cases are likely to be the result of social learning of evolution (as people would have avoided poisonous snakes so as to avoid harm). This implies that the theory is not completely valid as it cant explain the development of all phobias.
Give a strength of the two-process model of phobias (therapies)
The two-process model has good explanatory power. It explained how phobias could be maintained over time and this has important implications for therapies because it explains why patients need to be exposed to the feared stimulus. Once a patient is prevented from practising their avoidance behaviour, the behaviour ceases to be reinforced and so it declines. As flooding and systematic desensitisation have been found to be effective, this supports the validity of the explanation as it de-conditioning and preventing avoidance are effective, these may have been involved in the development of the phobia. Additionally, as the explanation is useful for creating effective therapies that improve people’s lives, this supports the external validity of the theory
