Definitions of abnormality Flashcards
(30 cards)
Define psychopathology
Study of the causes of mental mind diseases
Define abnormality
Something undesirable and needing treatment
-hard to diagnose mental illness
What are the 4 definitions of abnormality
Statistical infrequency
Deviation from social norms
Failure to function adequately
Deviation from ideal mental health
What is statistical infrequency?
when an individual has a characteristic that’s rare enough to be classed as abnormal
-mathematical definition using quantitative data
What does statistical infrequency assume?
-assumes that human characteristics which can be measures will form a normal distribution curve and most will cluster round the mean then reduce in frequency the further away from mean we go
Give an example of being considered ‘abnormal’ in statistical infrequency definition
Having an IQ of over 130 is considered to be a genius, but this definition suggests that this is a psychological disorder that needs treating
(Does it?)- some Beh can be statistical infrequent but desirable such as athletic ability
Give 2 strengths of statistical infrequency
Useful application
Representative of the population
How does statistical infrequency have useful application?
-We can use it for all 4 definitions
Eg, we can diagnose people with IQ under 70 with intellectual disability disorder as they’re 3 SD below average
-Means definition useful in clinics as been diagnosed as having intellectual disability means they can get help
How is statistical infrequency representative
It takes the whole population into account meaning its representative of the population so we can generalise the findings
Give 2 limitations of statistical infrequency
Some statistically rare behaviours are desirable
No consideration for cultural/gender diffs
How is some statistically rare behaviours being desirable a limitation?
Eg- Einstein had statistically rare IQ of 145 but we would class this is a very good thing rather than a psychological problem.
-Def assumes any statistically rare behaviours is problematic
Define failure to function adequately
Where a persons no longer able to cope with the ordinary demands of day to day living
What does FFA cause?
Personal distress and suffering
Observer discomfort
What did Rosenhan propose?
(FFA)
3 additional signs that can determine when someone’s unable to cope
- No longer conforming to standard interpersonal rules (eg, personal space)
- Experiences severe personal distress
- Behaviour is irrational or dangerous to themself or others
What does GAF stand for and what does it measure?
-Global assessment of functioning scale
-It enables us to see when someone starts to fail to function
What Are the 4 levels of the GAF scale
0-10, Persistent danger, scusidal
21-30, delusions, hallucinations
41-50, serious symptoms in every day life
81-90, minimal/absent symptoms
Give 2 strengths of Failure to function
-Considers the individual
-Face validity
How does the failure to function consider the individual? Why is this a strength?
Its the only definition to consider the patients experience therefore the individual may be happier with diagnosis
Give a counter to the FFA considering the individual
2 people could have the same symptoms and get different diagnoses
EG- one may feel they’re coping with everyday life but one may not with the same symptoms
Leading to a lack of consistency to diagnose people
Give a limitation of failure to function adequately
Symptoms could only be short term
-eg someone may not be able to cope post bereavement but not have depression as it’s normal to be sad for a short time
Define deviation from social norms
Defines abnormality based on a person’s behaviour diverging from the expectations of a society.
Define implicit
We make a collective judgement as a society what is right
What is antisocial personality disorder
-having an absence of prosocial internal standards
-associated with failure to conform to lawful and normative ethical behaviour
Give a strength of deviation from social norms
Useful definition- It’s used to diagnose people with psychological disorders like ASPD where the term strange is used to characterise behaviour
