definitions of abnormality Flashcards
statistical infrequency definition
occurs when an individual has a less common characteristic, for example being more depressed or less intelligent than most of the population
deviation form social norms definition
concerns behaviour that is different form the accepted standards of behaviour in a community or society
what is statistical infrequency
any relatively usual characteristic or behvaiour can be thought of as normal and any behvaiour that is unusual is abnormal
example of statistical infrequency- IQ and intellectual disability disorder
any characteristic the majority of peoples scores will cluster around the average, and the further we go above or below that average, the fewer people will have that score. this is called the normal distribution. the average IQ is set at 100. in a normal distribution, most people (68%) have a score in the range form 85 to 115. only about 2% of people fall below 70. those individuals scoring very low are very unusual or abnormal and are likely to be able to receive a diagnosis of a psychological disorder of intellectual disability disorder
when is statistical infrequency used
dealing with characteristics that can be reliably measured
how does statistical infrequency work
any human characteristic the majority of peoples scores will cluster around the average, and the further we go above or below that average, the fewer people will have that score. this is called the normal distribution
what is deviation form social norms
most of us notice people whose behaviour represents a deviation form social norms (when a person behaves in a way that is different form how we expect them to behave). groups of people chose to define behaviour as abnormal on the basis that is offends their sense of what is acceptable or the norm. as a society we decide what is right
deviation form social norms- norms are specific to the culture we live in
social norms are different for every generation and culture, so there are relatively few behaviours that are considered universally abnormal on the basis of breaching social norms. an example is homosexuality was considered abnormal in our culture in the past and continues to be seen as abnormal in some cultures
example of deviation form social norms - antisocial personality disorder
a person with antisocial personality disorder is impulsive, aggressive and irresponsible, according to the DSM-5 one important symptom of antisocial personality disorder is the absence of prosocial internal standards associated with failure to conform to lawful and culturally normative ethical behaviour. we are making the social judgement that psychopaths are abnormal because they don’t conform to our moral standards. psychopathic behaviour would be considered abnormal in a very wide range of cultures
strength of statistical infrequency - real-world application
-usefulness
-statistical infrequency is sued in clinical practice, both as part of formal diagnosis and a way to assess the severity of an individuals symptoms. for example, diagnosis of intellectual disability disorder requires an IQ of below 70 (bottom 2%). an example of statistical infrequency used in an assessment tool is the Beck depression inventory. A score of 30+ (top 5% of respondents) is widely interpreted as having severe depression. this shows that the value of the statistical infrequency criterion is useful in diagnostic and assessment processes
limitation of statistical infrequency - unusual characteristics can be positive
-infrequent characteristics can be positive as well as negative
-for every person with an IQ below 70 there is another person with an IQ above 130. yet we would not think someone with a high IQ is abnormal. similarly, we would not think of someone with a very low depression score on the BDI as abnormal. these examples show that being unusual or at one end of the psychological spectrum does not necessarily make someone abnormal –> means that, although statistical infrequency can form part of an assessment and diagnostic procedures, it is never sufficient as the sole basis for defining abnormality
evaluation of statistical infrequency - benefits vs problems
-some unusual people benefit from being classed as abnormal. for example someone with a very low IQ and is diagnosed with intellectual disability can access support services or someone with a very high BDI score is likely to benefit form therapy
-however, not all statistically unusual people will benefit form labels. someone with a low IQ who can cope with their chosen lifestyle would not benefit form the label. there is a social stigma attached to such labels
strength of deviation form social norms - real-world application
-usefulness
-deviation form social norms is use din clinical practice. for example, the key defining characteristic of antisocial personality disorder is the failure to conform to culturally acceptable ethical behaviour such as recklessness and aggression, violating the rights of others and deceitfulness. these signs of the disorder are all deviation from social norms. such norms are also used in diagnosis of schizotypal personality disorder, where the term strange is used to characterise thinking, behvaiour and appearance of people with the disorder –> shows deviation form social norms criterion has value in psychiatry
limitation of deviation form social norms - cultural and situational relativism
One limitation of deviation from social norms is the variability between social norms in different cultures and even different situations. A person from one cultural group may label someone from another group as abnormal using their standards rather than the person’s standards. For example, the experience of hearing voices is the norm in some cultures (as messages from ancestors) but would be seen as a sign of abnormality in most parts of the UK. Also, even within one cultural context social norms differ from one situation to another. Aggressive and deceitful behaviour in the context of family life is more socially unacceptable than in the context of corporate deal-making. This means that it is difficult to judge deviation from social norms across different situations and cultures.
evaluation of deviation form social norms - human rights abuses
-using deviation form social norms to define someone as abnormal carries the risk of unfair labelling and leaving them open to human rights abuses. historically this has been the case where diagnosis like nymphomania (women’s uncontrollable or excessive sexual desire) have been used to control women, or diagnosis like drapetomania (black salves running away) were a way to control slaves an avoid debate
-on the other hand it can be argued that we need to be able to use deviation form social norms to diagnose conditions such as antisocial personality disorder
