psychopathology 1.1 Flashcards
Definitions of abnormality, including deviation from social norms, failure to function adequately, statistical infrequency and deviation from ideal mental health.
the four definitions of abnormality
deviation from social norms
failure to function adequately
statistical infrequency
deviation from ideal mental health
deviation from social norms
a definition of abnormality where a behaviour is seen as abnormal if it violates unwritten rules (social norms) about what is acceptable in a particular society
social norms
a set of unwritten rules to follow
they are specific to the culture we currently live in and are often different for different generations and cultures
e.g in the past homosexuality was deemed as abnormal and now it’s not, homophobia is a crime however in come cultures homosexuality is still abnormal
strengths of deviation from social norms
looks at individuals abnormal behaviour and seeks to protect society from it
definition has a clear indication of what is considered normal and abnormal as most of us understand and are aware of social norms in our own culture
allows for developmental norms e.g. may be normal for one year old to be carried everywhere but abnormal if it was a 50 year old
limitations of deviation from social norms
based on western societal norms and reflects the majority which is a white population - Cochrane (1977) found that black people were more likely to be diagnosed with schizophrenia than white people however this wasn’t the same in countries with a majority black population e.g. Jamaica so there is a diagnostic bias
this definition doesn’t explain abnormality changing over time, homosexuality was not removed from the international classification of diseases until 1990
definition doesn’t make it clear how to deal with cultural differences in normal and abnormal behaviour e.g. walking barfoot in London compared to in a tribal community
doesn’t account for those who don’t conform to social norms but are not abnormal, such as those that are individualistic or eccentric in their behaviour
statistical infrequency
according to this definition, a behaviour is seen as abnormal if it is statistically uncommon, or not seen very often in society
uses statistics to determine the difference between normal and abnormal behaviour
when is a behaviour regarded as abnormal
if it is statistically uncommon i.e. not present often or regularly per society e.g. about 1 in 300 people worldwide have schizophrenia making it an abnormal condition
what type of curve is used to represent the proportions of a population who share a particular characteristic?
distribution curve
where does the mean fall in the distribution curve?
in the centre
where do outliers fall on the distribution curve?
at each end of the curve
strengths of statistical infrequency
uses an objective, standardised measure which means that it is reliable
distribution curves are based on real data and therefore should be unbiased
weaknesses of statistical infrequency
depression is regarded as abnormal behaviour, yet it is so prevalent (1 in 6 adults in the uk have depression) which measn that it isn’t statistically deviant, hence using this as a measure of abnormality is unrepresentative
having an IQ of 130 might be regarded as advantageous rather than as evidence of ‘abnormality’
failure to function adequately
states individuals are abnormal when they are unable to cope with everyday life and this is evident in their behaviour
e.g. distress leading to not being able to function
what did rosenhan and seligman suggest?
that certain elements jointly determine abnormality
features of personal dysfunction (5)
personal distress
maladaptive behaviour
observer distress
unpredictable behaviour
irrational behaviour
