Psychopathology
Definitions of abnormality
Statistical infrequency
Easiest way to determine
Any common behaviour or characteristic can be thought of as ‘normal’ and any
unusual behaviour as abnormal – has changed over time.
e.g. IQ and intellectual disability disorder
- useful when dealing with characteristics that can be reliably measured e.g.
intelligence
- in any human characteristic, the majority of people’s scores will cluster around the
average and the further we go from it, the fewer people will attain it : normal
distribution
Evaluation:
Real-world application
o Useful in clinical practice – formal diagnosis and severity of an
individual’s symptoms
o Example of statistical infrequency used in an assessment tool is the Beck
depression inventory (BDI)
Face validity
o Abnormality is when something does not usually happen
Objective
o Mathematical nature
o No opinion involved so no bias
Unusual characteristics can be positive
o Wouldn’t think of someone as being abnormal for having an abnormally
good level of intellect for example
o One end of the psychological spectrum is not necessarily bad
o Never sufficient as the sole basis for defining abnormality
Cultural differences
Inflexible
o Contradiction between abnormal behaviour according to diagnostic
manuals and criteria for defining mental health issues
Abnormal behaviours can occur frequently
o E.g. mental health problems
Benefits vs problems
o Some people benefit from being classed as abnormal e.g. access to
support services for help
o Not all statistically unusual people benefit from labels – social stigma
attached to labels
Deviation from social norms
, When a person behaves differently from how we would expect according to
societal standards of behaviour
Groups of people choose to define behaviour as abnormal on the basis that I
offends the sense of what is ‘acceptable’ of the norm
Make a collective judgement as a society on what is ‘right’
They are culture-specific… differ between generations and cultures
- Very few behaviours are abnormal for breaching social norms e.g.
homosexuality
e.g. antisocial personality disorder
- makes someone aggressive, impulsive and irresponsible
- according to the DSM-5 (manual used to diagnose mental disorders) a symptom of
antisocial personality disorder is ‘absence of prosocial internal standards associated
with failure to conform to lawful and culturally normative ethical behaviour –
psychopaths are abnormal because they don’t conform to our moral standards
Evaluation:
Real-world application
o Used in clinical practice
o Key defining characteristic of antisocial personality disorder is failure to
conform to culturally acceptable ethical behaviour
o Signs of the disorder are all deviations from social norms
o Schizotypal personality disorder – norms play a part in diagnosis –
‘strange’ is used to characterise their thinking, behaviour and appearance
o Can help the patient
Cultural and situational relativism
o Differing standards of ‘normality’
o E.g. hearing voices is normal in some cultures
o Aggressive and deceitful behaviour in the context of family life is more
socially unacceptable than in the context of corporate deal-making
Human rights abuses
o Carries the risk of unfair labelling and leaves people open to human rights
abuses
o Historically: nymphomania – used to control women, drapetomania – used
to control slaves and avoid debate
PARAPHILIAS
- Psychologists have become less inclined to classify people using a single
definition
- E.g. paraphilias used to be defined as deviations from social norms
- In the DSM-5 system they are only classified as mental disorders if they involve
harm or distress to the person themselves or other people
Flexibility
o Dependent on situation and age
o Range of factors taken into account
Used to justify removal of unwanted persons from society
, o What is normal changes temporally
o E.g. the DSM used to consider homosexuality a disorder
Failure to function adequately
- Person becomes abnormal when they cannot cope with the demands of
everyday life
- They cannot maintain basic standards of nutrition and hygiene, hold down a job
or maintain relationships
- May do irrational things that pose a danger to themselves or others
Rosenhan and Seligman (1989) – signs that someone is not coping are:
1. When a person no longer conforms to standard interpersonal rules e.g. making
eye contact and respecting personal space
2. When a person experiences severe personal distress
3. When a person’s behaviour becomes irrational or dangerous to themselves or
others
e.g. intellectual disability disorder
- diagnosis would not be made solely on the basis of having a low IQ – they must also
be failing to function adequately
Evaluation:
Sensible threshold for professional help
o Around 25% of the UK will experience a mental health problem in any
given year according to Mind
o Many people continue despite severe symptoms
o Treatment and services can be targeted to those who need them most –
those who are unable to function adequately may seek professional help
or be referred by others
Behaviour is observable
o Can be seen by others around the individual
o Useful if they are incapable of helping themselves
Discrimination and social control
o Easy to label non-standard lifestyle choices as abnormal
o In practice it is hard to differentiate between deviating from social norms
and failing to function adequately
o Living ‘off-grid’, favouring high-risk leisure activities, unusual spiritual
practices e.g. base jumpers, spiritualists, new age travellers
o At risk of being unfairly labelled abnormal and their freedom of choice
may be restricted
COUNTERPOINT
o Acknowledges experience of the patient
o Whether they are suffering
Failure to function may not be abnormal
o E.g. in cases of bereavement
o May be unfair to give someone a label that may cause them future
problems just because they react to difficult circumstances
