Psychopathology: Definitions of abnormality Flashcards
What are the 4 definitions of abnormality?
- Deviation from social norms
- Failure to function adequately
- Statistical infrequency
- Deviation from ideal mental health
What is a deviation from social norms?
Where behaviour is seen as abnormal if it violates unwritten rules (social norms) about what is acceptable in a particular society. Behaviour may be comprehensive.
Sometimes these are written (explicit) and form laws that govern behaviour. Sometimes though, these norms of behaviour are unwritten (implicit) but generally accepted (e.g. not standing too close to people at a cash machine).
Whether explicit or implicit, social norms allow for the regulation of normal social behaviour. All societies have standards, or norms, for appropriate behaviours and beliefs (expectations about how people should behave and what they should think).
What are 2 examples of deviation from social norms?
Laughing at a funeral (implicit)
Exposing yourself in public (explicitly - defined by law)
A03: Deviation from social norms
+ Practical application
+ Flexible
- Vary between cultures
- Social norms change over time
A03: Deviation from social norms: Practical application
The social dimension of this definition can help both the abnormal individual and the wider society. For example, intervention by society may protect citizens from the potentially dangerous behaviours of abnormal individuals. Further, intervention may also help the abnormal individual (who may not be able to help themself) by teaching them to interact successfully in society and avoid potentially dangerous consequences of abnormal behaviour.
A03: Deviation from social norms: Flexible
Social norms are flexible to account for the individual and situation. For example, throwing tantrums and hitting people is socially normal for a toddler, but would be a sign of mental disorder in adulthood. Similarly, walking around naked in your house might be normal, but walking around naked in the street would be a sign of mental disorder.
A03: Deviation from social norms: Vary between cultures
Social norms differ between cultures and this may be problematic. In British culture, it is considered to be polite to finish the food on your plate at mealtimes. However, in India, to finish all food from your plate is a sign that you are still hungry. This is a limitation because shows that what is considered ‘normal’ in one culture may actually be ‘abnormal’ in another. This means that this definition does not consistently produce an accurate definition of abnormal behaviour.
A03: Deviation from social norms: Social norms change over time
The Social norms definition can be questioned, as social norms change over time and therefore a behaviour that broke social norms and was considered abnormal in 1950 may not be viewed as abnormal today. Being an unmarried mother in the 1940s and 1950s would be breaking social norms and therefore this behaviour was classed as abnormal. Many of these women were sectioned as ‘moral imbeciles’ and society demanded that they “give up” their babies. This is a limitation because as this example shows, it is not the individual who has changed but the classification of the behaviour by society. This brings into question the validity of using this definition alone to define abnormality.
What is statistical infrequency?
A person’s traits, thinking or behaviour are classified as abnormal and rare. It’s a quantitative definition that requires a clear cut-off point usually using a normal distribution curve.
This approach defines abnormality as a behaviour that deviates from the ‘average.’ The idea behind this approach is that the less frequently a behaviour occurs in people, the more likely it is to be abnormal. The difference between normal and abnormal is therefore one of quantity rather than quality the majority of people are normal with the minority of people being abnormal
A03: Statical infrequency
+ Clear definition
- Not always accurate
- Ethnocentric
- Left open to criticism
A03: Clear definition
A strength of the Statistical Infrequency definition of abnormality is that offers the prospect of clear guidelines for identifying behaviours as normal and abnormal. For example, the definition introduces an element of objectivity into the process of defining abnormality so that different mental health care workers can all view the same kind of behaviour in the same kind of way. This is a strength because it offers a more scientific way of measuring abnormality, reducing subjectivity and therefore leading to a more accurate way of defining abnormality.
A03: Not always accurate
A criticism of this definition is that it suggests that anyone who differs from the ‘average’ is technically abnormal. For example, it doesn’t take into account the desirability of behaviours, highly intelligent people are statistically rare and are thus, according to this definition, abnormal. This is a weakness as just because somebody falls outside of the statistically common area of the distribution curve, it doesn’t necessary mean that they are able. Therefore, suggesting that the statistical infrequency definition is not always accurate in defining abnormality.
A03: Ethnocentric
A weakness of this definition is that it can be criticised as being ethnocentric. For example, cultures differ in terms of what they consider normal behaviour. It would be very unusual for someone in Great Britain to take an extended rest period during the working day; however, in other cultures, this is very common. This is a weakness because the definition cannot be applied/generalised to every culture and therefore using this definition may lead to some individuals being inaccurately defined as being abnormal.
A03: Left open to criticism
A further weakness is that the statistical approach definition requires a decision about the point at which behaviour becomes statistically abnormal. For example, it is not clear at which point energetic and excitable behaviour from a child becomes a ‘problem’ behaviour requiring specialist intervention. This is a problem as the definition is left open to criticism, such apparent arbitrariness makes it difficult to accurately define abnormality.
What is deviation from ideal mental health?
Occurs when someone does not meet a set of criteria for good mental health. Jahoda (1958) identified 6 features of ideal mental health.
