what is abnormality?
behaviour which is deviant from what is considered normal
what are definitions of abnormality?
ways to identify if a person’s behaviour deviates from normal behaviour
what are the four definitions of abnormality?
-statistical infrequency
-deviation from social norms
-failure to function adequately
-deviation from ideal mental heath
what does the statistical infrequency definition argue?
that behaviours that are statistically rare should be seen as abnormal
when is something classed as statistically rare?
it depends on normal distribution:
-most people will be around the mean for the behaviour, with declining amounts of people away from the mean
-any individual who falls outside ‘the normal distribution (usually about 5% of the population) are perceived as being abnormal
how is abnormality determined?
(statistical infrequency)
abnormality is determined by looking at the distribution of a particular behaviour within society
IQ is…
an example of an abnormality that can be defined with statistical infrequency
statistical infrequency: IQ
-if we took a representative sample of adults in the UK, we would find approx 65% of adults with an IQ score somewhere between 85 and 115 (considered normal as it is what most people score)
-only 2.5% of the sample would have scores that fall at either extreme of the normal distribution curve
(eg: there would be 2.5% with a very low score and 2.5% with a very high score)
ends of the IQ spectrum:
-both ends of the spectrum would be considered “abnormal” because so few people achieve these scores
-those in the bottom 2.5% are likely to be labelled as having intellectual disability disorder (mental retardation)
IQ - statistical infrequency
(percentages)
-around 68% of people fall between 15 points of 100
-around 95% of people fall between 30 points of 100
-less than 5% are at the extremes
strength of statistical infrequency as a definition of abnormality:
an objective measure of abnormality and a useful assessment tool
ao3 / strength - an objective measure of abnormality and a useful assessment tool
P - an objective measure of abnormality and a useful assessment tool
E - due to its mathematical nature, it’s clear what’s defined as abnormal (2.5%)
↳ it allows for those with severe symptoms of a mental illness to be identified by comparing to statistical norms / eg: the Beck depression inventory (BDI), a score of 30+ (top 5% of respondents) is widely interpreted as indicating severe depression
L - this is a strength because statistical deviation is a useful part of clinical assessment and it is not based on subjective opinion so it is free from bias
criticisms of statistical infrequency as a definition of abnormality:
-the definition fails to distinguish between desirable and undesirable behaviours (not all infrequent behaviours are abnormal)
-not all abnormal behaviours are infrequent
-there is no consideration of cultural differences
ao3 / criticism - the definition fails to distinguish between desirable and undesirable behaviours
P - not all infrequent behaviours are seen as abnormal
E - IQ scores over 130 are just as unusual as those below 70, but we wouldn’t think of super-intelligence as an undesirable characteristic that needs treatment
↳ just because certain characteristics are statistically abnormal doesn’t mean they require treatment to return to normal
L - this is a serious limitation to the concept of statistical infrequency and means it would never to used alone to make a diagnosis
ao3 / criticism - not all abnormal behaviours are infrequent
P - not all abnormal behaviours are infrequent
E - some behaviours are seen as abnormal even though they are statistically frequent
↳ (eg: depresssion) 27% of elderly people are thought to suffer from depression and 25% of the population will experience depression or mental illness at some point in their lives
L - therefore the statistical infrequency definition of abnormality is not always accurate as it can’t always identify abnormal behaviour
ao3 / criticism - there is no consideration of cultural differences
P - there’s no consideration of cultural differences
E - beliefs about abnormality differ between cultures, what is acceptable in one culture may be seen as abnormal in another
↳ this definition argues that the population of the world are contained within the normal distribution
↳ this means that an abnormality could be seen as widespread in one culture because of its comparison with the rest of the world (eg: hearing voices of spirits is highly valued in some cultures but a western society would view this as abnormal behaviour)
L - therefore the definition of statistical deviation is culturally relative
what are social norms and who are they set by & followed by?
rules that society has about how people should think and behave
↳ set by that social group, and followed by those socialised in that group
what two things can social norms be?
explicit (set down as conducts or laws, breaking these rules may result in punishment)
implicit (understood but not stated formally)
what is cultural relativism?
the idea that social norms and values are culture specific and no-ones culture is superior to another culture
↳ this means there are few behaviours would be considered universally abnormal on the basis that they breach social norms
what is deviation from social norms as a definition of abnormality?
any behaviour that deviates from social norms in that community may be seen as abnormal to that community
what is the difference between statistical infrequency and deviation from social
norms?
the deviation from social norms definition distinguishes between socially desirable and undesirable behaviours
what is an example of deviation from social norms?
antisocial personality disorder (or psychopathy)
how does a person with antisocial personality disorder act?
the person is impulsive, aggressive and only pleases themselves
an important symptom of antisocial personality disorder:
iin the DSM:
an absence of prosocial internal standards and a failure to conform to lawful or culturally ethical behaviour
