PP - abnormality Flashcards
what are the 4 definitions of abnormality
- statistical infrequency
- deviation from societal norms
- failure to function adequately
- deviation from ideal mental health
what is psychopathology
the field of study that deals with mental, emotional and behavioural problems
what is involved in the research in psychopathology
- diagnosis
- classification
- causation
- prevention
- treatment
what is statistical infrequency
statistically rare behaviour based on normal distribution
- most people fall into the middle of the bell curve
- statistically abnormal people fall to either end of the bell curve
example of statistical infrequency
68% in the middle section of IQ - 100 average
+130 = rare
<70 = rare
limitations of statistical infrequency
- difficult to generalise as it groups different types of abnormalities
- unusual characteristics can be seen as positive like high IQ
strengths of statistical infrequency
- real-world application for diagnosis e.g. Beck’s depression inventory
what is deviation from societal norms
- deviating from the unwritten rules of societies view of normal
- those who demonstrate undesirable behaviours are social deviants
limitations of deviation from societal norms
- subjective - everyone has different norms (relies on context of culture, historical time and individual differences)
- unethical to label people - may cause distress and judgement which could worsen a condition
strengths of deviation from societal norms
- real-world application in clinical practice (gives defining characteristics for antisocial personality disorder and schizotypal personality disorder)
what is failure to function adequately
- not being able to cope with the stresses of everyday life
- displays defined characteristics
what are the defining characteristics of failure to function adequately
- unpredictability
- personal distress
- irrationality
- unconventionality
- maladaptive behaviours
- observer discomfort
- violation of moral standards
e.g. hoarding
limitations of failure to function adequately
- it is easy to label non-standard lifestyle choices as abnormal e.g. not having a job may be seen as a ‘failure’ but could be a way of someone’s life
- failure to function can be normal at some points e.g. during times of grief
strengths of failure to function adequately
- represents a sensible threshold for when people need professional help
what is deviation from ideal mental health
- looks for the absence of well-being
- Jahoda said there should be 6 characteristics exhibited to demonstrate normal behaviours
- absence of any of those behaviours indicates abnormality
