PSYCHOPATHOLOGY
DEFINITIONS OF ABNORMALITY (AO1 + AO3)
Definition 1: Statistical inferquency
- Behaviour that is rarely seen as
normal.
- Defining abnormality in terms of
STATISTICAL
INFREQUENCY
‘statistics’ — the number of
times something has been
done.
- Often given in percentages
EXAMPLE
IQ and intellectual disability
disorder
- The average is 100.
- Individuals below 70 are
diagnosed due to statistical
infrequency (2%).
over the general population.
EVALUATION
• REAL-LIFE APPLICATION - It’s a useful
and required part of clinical assessment.
It’s good for diagnosing a lot of disorders
that include comparison to some statistical
norms.
• POSITIVE INFREQUENCY - Engaging in
rare behaviour styles doesn’t necessarily
mean a person requires treatment (e.g. IQ
of over 130 isn’t undesirable). Shows that
statistical infrequency isn’t enough to make
a diagnosis.
• LABELING - Some people with disabilities
might live normal lives and not need a label
emphasising their shortcomings.
Definition 1: Statistical inferquency
- Based on social context.
- Societies and groups make
DEVIATION FROM
SOCIAL NORMS
collective ‘judgements’ about
‘correct’ behaviours
- Has cultural context as there
are very few behaviours that
are considered universally
abnormal.
- Has historical context (e.g.
homosexuality)
EXAMPLE
Antisocial personality
disorder (APD)
- formerly known as
‘psychopathy’
- failure to conform to ‘lawful
and culturally normative
ethical behaviour’
EVALUATION
• NEVER ENOUGH - Deviation isn’t the sole
explanation to mental disorders (e.g. APD
is an example, but it doesn’t take into
consideration harming others)
• CULTURALLY RELATIVE - what is
considered abnormal varies from culture to
culture (e.g. somewhere it’s ok to hear
voices, in the UK it’s not)
• HUMAN RIGHTS ABUSES - Too much
reliance on this definition can lead to it. The
question of eccentric vs. abnormal.
Diagnoses were sometimes used for social
control (nymphomania = women attracted
to working class men; drapetomania =
black slaves trying to escape)
Definition 3: Failure to function adequately
- Inability to cope with everyday
FAILURE TO
FUNCTION
ADEQUATELY
living and function adequately (e.g.
not being able to keep a job,
relationship, maintain hygiene…)
- Rosenham and Seligman
proposed signs of failure to cope:
1) Personal distress
2) Irrational/dangerous behaviour
3) Disregard interpersonal rules
EXAMPLE
Intellectual disability discorder
- Even if somebody has a
statistically rare low IQ, they
can’t be diagnosed unless
that doesn’t tamper with their
ability to function.
EVALUATION
• PATIENTS’ PERSPECTIVE- Takes into
account the patient’s feelings and experience.
• ECCENTRIC VS ABNORMAL- People who do
extreme sports or live alternative lifestyles may
be considered abnormal this way.
• SUBJECTIVITY - In spite of checklists and
standardised procedure, there’s a question of
whether psychiatrists should be allowed to
judge the distress/suffering of a patient

EVALUATION
EXAMPLE
- Any form of mental state that is
different from the normal/ideal
mental state
- Marie Jahoda provided a list of
Never keeping a job
- May be a sign of deviation
• CULTURALLY RELATIVE- Some of Jahoda’s
HOWEVER…
1. No symptoms or distress
2. Rational and good selfperception
3. Self-actualisation
4. Coping with stress
5. Realistic view of the world
6. Good self-esteem and lack
guilt
7. Independent
8. Successfully work, love, enjoy
leisure
- This could also be a sign of
failure to function adequately.
classifications are specific to Western European
and North American (individualist) cultures
where self-actualisation is valued over
community.
• UNREALISTIC - Most people deviate from ideal
mental health, at times at least.
• REAL-LIFE APPLICATION - Makes it clear to
which ideal people should strive to achieve.
