Psychpath- The 4 definitions of abnormality Flashcards
what are the 4 definitions of abnormality
- Deviation from social norms
- Statistical infrequency
- Failure to function adequately
- Deviation from ‘ideal mental health’
- what does deviation from social norms mean?
- How does it make others feel?
- What does ‘Deviant’ mean and entail
- Who sets the standards for society?
- Deviation from social norms, is when someones behaviour and thinking is classed as abnormal due to it violating the (unwritten) rules of what is acceptable behaviour in a social group.
- Their behaviour could confuse others or make them feel threatened
- Deviant behaviour is being anti-social or undesirable behaviour from the view of the majority of society
- The standards of acceptable behaviour is set by the social group
What are the 2 strengths of Deviation from social norms
1- A strength is that it is flexible dependent on situation and age. A social norm is to wear full clothing whilst out shopping, but a bikini is acceptable on a beach. It is also socially acceptable to drink milk out of a bottle with a teat if you are a baby, but not as an adult.
2- Adhering to social norms means that society is ordered and predictable which helps society function. This is argued to be advantageous because it distinguishes the difference between desirable and non-desirable behaviours
What is a weakness of Deviation from social norms
A weakness is that it lacks Temporal validity because what is socially acceptable today, may not have been 50 yrs ago. For example, homosexuality was regarded as insane and was sent to a mental institute, but now it is accepted in society. Therefore, defining abnormalities in terms of deviation from social norms, is a danger in creating morals that could change in the future
- What is Statistical infrequency
2.What do use to measure Statistical infrequency and why
- Statistical infrequency is a mathematical way of defining abnormality. This works on the idea that ‘abnormality’ is based on infrequency, so if a particular person’s behaviour occurs rarely in society, it is abnormal.
This is because human attributes fall into a normal distribution within the population. - Standard deviation is what we use to measure Statistical Infrequency because it is necessary to be clear about, how rare a trait needs to be before we class it as ‘abnormal’
What is an example of someone having Statistical Infrequency
AN example is someone with very high IQ because they are so unusually intelligent that it is rare and abnormal but that doesn’t mean it is a negative thing to have high IQ
What does statistical infrequency have - n_ cu______ b____
and what does it apply to - mul____ ge________
It has no cultural bias
and it applies to multiple generations
Explain what standard distribution is and how the ‘mean’ works
The mean is the central average (mean), where the rest of the population falls symmetrically above and below that mean.
Standard Deviation, as a measure informs us how far scores fall on either side away from that mean.
Explain how SD works when using IQ as an example
IQ is a characteristic that falls into a normal distribution.
So, 68% of the population fall within one standard deviation from the mean.
95% of the population fall within two standard deviations from the mean.
As the mean of IQ is 100 and the standard deviation for IQ is 15 that means that 68% of the population will score between 85- 115 on an IQ test and 95% of the population will score between 70 and 130.
SD states that the 5% of the population that fall More than 2 Standard deviations from the mean are ‘abnormal’.
So, in the IQ example people who score Below 70 and Above 130 are Abnormal.
What is a strength of Statistical Infrequency
A strength is that it is appropriate when using the criterion to define what abnormality is.
For example, any individual whose IQ is more than 2 Standard Deviations (SD) Below the mean, is judged as someone having a mental disorder, but only if or when they are failing to function adequately.
What is another strength of Statistical Infrequency
-A strength is that SD looks at the whole picture, because it takes all the population into account, so it can give a useful insight into the whole picture of a particular characteristic.
-The mathematical nature of this definition means that it is clear what is defined as abnormal and what is not. There is No opinion involved which means there is No Bias.
What is a weakness of Standardised infrequency
1- SD is inf______ Scores in the top and bottom 2._% of po_______ are ab________ but some mental ill_____ wouldn’t fit. E.G 3%of the population suffer from ___D and some won’t be seen as abnormal because they are in _ SD away from the m____.
This means the defini____ and the current crit_____- for defining me_____ h______ issues are at odds with each other.
2- Furthermore, some abnormal behaviours can occur f_________ E.G. d_______, as 2_% of pop may experience it in their lifetime. some are so frequent, it no longer is shown as a______ on SD.
3- No cons______ for cul_____ di________ as it says the normal distribution is the w______ population. Meaning that a________ could be wid_________ in on_ cu___, compared to the rest of the world
1- However, SD is quite inflexibility. It states that scores in the top and bottom 2.5% of the population are abnormal, but but some mental illness that would not fit within that definition. For example 3% of pop suffers from OCD but some may not be seen as abnormal because they are within 2 standard deviations of the mean. This means that the definition and the current criteria for defining mental health issues are at odds with each other.
2- Furthermore, some abnormal behaviours can occur frequently, Depression is an example, where it is argued that 25% of the population will experience a mental health issue at some point in their lives, which demonstrates that some mental illnesses are so frequent in humans, that it no longer is counted as abnormal.
3- There is no consideration of cultural differences at all as it argues that the population of the world are contained within the normal distribution. This ultimately means that abnormality could be widespread in one culture because of its comparison with the rest of the world.
What is the definition of ‘Failure to function adequately’
and what is an example
The inability to come with everyday life
E.G. They can’t keep a job, maintain jobs or relationships, hygiene or nutrition
Who researched ‘Failure to function adequately’
what did they propose
Rosenhan and Seligman (198_)
They proposed the signs of failure to cope:
- No longer conform to interpersonal rules (communications and relationships in an organization)
- They experience personal distress
- They behave in a Irrational way
Name the disorder that is an example of Failing to function adequately
Intellectual Disability Disorder- having a low IQ is statistically infrequent, as well as not being able to cope with demands of everyday life.
