Definitions of abnormality Flashcards
what is statistical infrequency?
- someone is mentally abnormal if their condition is rare in the population
- rarity is judged using objective stats
- comparing the individuals behaviour to the rest of the population
what is a normal distribution curve?
- populations average spread of characteristics
- mean median and mode all at highest point= most common
- at each end there are fewer ppl with those charcateristics
how to use a normal distribution curve to find abnormal behaviour?
- compare individuals to the population and identify those at extreme ends
Evaluating statistical infrequency: strength, those being assessed have been evaluated objectively
- individuals who are assessed as being abnormal have been evaluated objectively
- better than subjective opinion of a clinician
- deciding if a client is coping or not is a vague concept, 2 observers may disagree
Evaluating statistical infrequency: limitations, the psychological community decides the cutoff for what is statistically infrequent
- get to decide what is rare enough to be statistically infrequent to be abnormal
- this is a subjective decision with real implications
- defining intellectual disability as 70 IQ and under
- means those just above 70 dont get support
Evaluating statistical infrequency: limitations, theres a range of common psychopathologies
- anxiety and depression= common psychopathologies
- NHS found 17% of people surveyed met the criteria for common mental health disorders
- definition isnt appropriate in considering societies high incidence of mental health disorders
Evaluating statistical infrequency: limitations, not all statistically infrequent traits are negative
- this definition would include those who are on the other end of the scale
- 130 IQ is just as statistically rare as 70 IQ
- good definition of abnormality shouldnt include people with high intelligence
- saying they have psychopathology and need additional support
what is the failure to function adequately?
- abnormal if they cant cope in their daily lives
- including their ability to interact with the world and meet their challenges
Rosenhan and Seligman’s features of failure to function adequately:
- maladaptive behaviour
- personal anguish
- observer discomfort
- irrationality
- unconventionality
what is maladaptive behaviour?
- individuals behave in ways that goes against their long-term interests
what is personal anguish?
- the individual suffers from anxiety and distress
what is observer discomfort?
- individuals behaviour causes distress to those around them
what is irrationality?
- difficult to understand the motivation behind the individuals unexpected behaviour
what is unconventionality?
- behaviour doesnt match what is commonly expected by society
Evaluating failure to function adequately: limitations, decision as to whether someone is coping is subjective
- it is based off the clinicians opinion
- their judgement may be biased
- two observers my not agree if someone is managing
