>psychopathology - definitions of abnormality Flashcards
4 definitions of abnormality?
-statistical infrequency
-deviation from social norms
-failure to function adequately
-deviation from ideal mental health
what is meant by statistical infrequency?
-defines abnormality as how common something is/how often behaviour is observed
-statistics eg mean, mode, median are used to define typical -> can then be applied to behaviour
-anything uncommon/not often in society -> socially abnormal
examples of statistical infrequency?
-IQ scores
-show size
-typical age to have a baby
explain what it would look like if IQ scores were graphed on a statistical infrequency graph:
-majority of human characteristics are evenly distributed, most clustering around the mean
-further away from the mean -> more uncommon behaviour is
-%=y, IQ=x
how would you estimate where a particular behaviour falls on a statistical infrequency graph?
look at percentages of SD, figure out from there
advantages of statistical infrequency?
-model has real world application, used in diagnosis of intellectual disabilities, Becks depression inventory (top 5% = severe depression)
-objective -> statistics determine abnormal behaviour, eliminates human bias -> more reliable, however cut off point between normal + abnormal may be subjectively determined
disadvantages of statistical infrequency?
-unable to distinguish desirable + undesirable behaviours, eg high IQ = abnormal but not undesirable, depression = common but not desirable
what is meant by deviation of social norms?
-‘norms’ tell individuals what is socially acceptable behaviour
-can be implicit/written in law
-anyone that doesn’t follow these norms classed as abnormal
examples of deviation from social norms?
-clothing: wearing a bikini top to school, dressing inappropriately to a formal black tie event
-unfortunately, in some cultures/countries, homosexuality is viewed as against social norms, some even written in law
-anti-social personality disorder (psychopathy) is classed by DSM as absence of prosocial internal standards -> don’t conform to moral standards/norms
advantages of deviation from social norms?
-able to distinguish between desirable + undesirable behaviours, allowing people to live together in a society in harmony
disadvantages of deviation from social norms?
-can lead to abuse of human rights, anyone who doesn’t follow social norms is deemed as mentally ill to exclude non-conformists. some psychologists say that some modern mental illness categories are abusing peoples right to be different
-norms vary over time + across cultures, what may have been historically a norm is no longer a norm, one norm in a certain culture may not be the norm for another culture eg hearing voices in african tribes
what is meant by failure to function adequately?
-inability to cope with the demands of everyday life eg not being able to hold down a stable relationship/job, not washing clothes regularly, not eating regularly
-may cause distress to the individual due to their inability to cope
-one of the definitions that considers FFA can cause discomfort/distress to others, eg individual with schizophrenia may be unaware of symptoms themselves, but concerns family + friends
Seligman + Rosenhans criteria?
-not conforming to standard interpersonal rules (eg eye contact, personal space)
-experiencing severe personal distress
-behaviour may be irrational/dangerous to themselves + others
-depression may manifest as FFA eg lack of motivation to get up in the morning, also may cause distress/discomforts to family + friends as well as themselves
-some disorders eg intellectual disability disorders require observance of FFA to gain diagnosis
advantages of FFA?
-takes into account subjective view of patient, more accurate, close + personal diagnosis
-considers feelings of not just individual, but those surrounding them
disadvantages of FFA?
-abnormality depends on person making judgement, some may not recognise that they are failing the function, therefore judgement is based on their subjective opinion. however can be made objective eg checklists
-some dysfunctional behaviours may actually be deemed as functional eg in depression, individual may gain attention/help from due to their symptoms, making behaviour functional
