Definitions of abnormality Flashcards
Why do we need to be able to identify abnormal behaviours
In order to recognize and diagnose psychological disorders we must be able to identify behaviours that are abnormal
What are four ways of defining abnormality
Statistical frequency, Deviation from social norms, faliure to function adequately and deviation from ideal mental health
What is deviation from statistical norms
When we measure how frequently a behaviour occurs within a population, and behaviours which occur the most rarely (appear on the far left or right of a normal distribution curve) are defined as abnormal
What is a strength of devaition from statistical norms
It provides an objective clear cut off point for abnormal behaviours, which is useful when diagnosing conditions. For example, any individual whose IQ is two standard deviations below the mean is judged to have a mental disorder. However, these decisions are often made in conjunction with faliure to function adequately, suggesting this is a tool to be used alongside others
How is cultural bias an issue in abnormality as deviation from statistical norms
Behaviours which occur infrequently in one culture may be statistically frequent in another. For example, hearing voices is common experience in some cultures whilst in the west it’s a symptom of Sz. This means there is no universal measure for abnormal behaviour
What is an issue for measuring all infrequent behaviours as abnormal in abnormality being statistical deviation
Not all abnormal behaviour is undesirable, for example having an insane IQ is considered desirable, and in contrast, not all normal behaviours are desirable, such as depression, which is relatively common and would be considered normal behaviour under this anlysis. This means this method is unable to distinguish between desirable and indesirable behaviours
What are social norms
Social norms are norms created by a group of people and they exist within a society. These are acceptable behaviours defined by the group, and are adhered to by those socialised into that group
What is deviation from social norms as an explination for abnormality
It defines anyone who deviates from social norms and behaviours as abnormal.
What are implicit versus explicit rules
Explicit rules are often governed by the law whereas implicit rules are usually determined by social rejection
Why are many social norms created
They are funcitonal, such as politeness, which helps improve interpersonal relationships
Why is time an issue for defining abnormality as deviation from social norms
What is acceptable socially changes constantly, with behaviours currently acceptable being seen as abnormal in the past. Homosexuality was included under sexual and identity disordders in past DSM’s, whereas now it’s acceptable in most countries.
With social changes so frequent, what did Thomas Szasz claim the concept of mental illness was
He claimed mental illness was simply a way to exclude nonconformists from society
Who claimed that mental illness was simply a way to exclude nonconformists from society

What is a strength of defining abnormality as deviation from social norms
It can differentiate between desirable and undesirable behaviours. This method takes into account the behaviours effect on other people, as ideally social rules are established in order to help people live together. Therefore in this definition abnormal behaviour will be behaviour which is harmful to others. This makes the definiton useful as undesirable behaviours will be more likely to alert others that the person may need help
Why is culture bias an issue for defining abnormality as deviation from social norms
The norms of a society are defined by their culture. Classification systems like the DSM are based almost entirely off of norms of the dominant western culture. When these criteria are applied to both different western subcultures as well as different cultures overall, it creates invalid classifications.
