Q: Describe and evaluate the concepts of abnormal behaviour

When we talk about abnormal behaviour it is not always clear what we mean, as the definition of abnormality seems to change every 20 years or so. Not to mention the fact that different cultures have there own ever changing ideals on the subject. Is mental illness to do with gods and demons, is it simply chemical imbalances in the brain or is it, as Thomas Szasz puts it; just eccentricities, with the term mental illness being thought up by the state, as a way of controlling the masses?

     As both the elements and definitions of abnormality are ever changing, it would be an impossible task to talk about all the different theories and explanations for mental illness. So in this essay I will be focusing on the 7 elements of abnormality as described by Rosenhan and Seligman and the 4 definitions of mental abnormality fond in the “New Webster’s English Dictionary”. I will also have a brief look at Thomas Szasz’s claim that, “there is no such thing as abnormal behaviour; it is societies way of controlling people.”

      The 4 definitions of abnormality are: a statistical infrequency, any defect from the social norm, not to have mental health and an inability to function adequately in society. In the first part of this essay, I will be looking at these definitions and I will be examining both their strengths and weaknesses.

        The science of psychology and mental illness is based mainly on the behaviour of the majority. This behaviour being seen to be normal, and anyone who strays outside of these relatively narrow boundaries being considered abnormal, hence the expression “statistical infrequency”. Simply put, someone who does not fit the general rule is not normal. There are obvious problems with this as a definition of mental illness e.g. having a high IQ goes against the statistical, norm but you wouldn’t say that someone with a high IQ was mentally ill. Why that would be a frankly ridiculous accusation. However based on this definition of mental illness it would be perfectly reasonable to suggest so. Although if you take this to be a definition simply of mental abnormality and not of mental illness then yes, having a high IQ is a mental abnormality, but surely this argument would also lead to the point that mental illness and mental abnormality are two completely different things and should in no way be linked together. Just like having six toes is physically abnormal but is not a physical disability and physical abnormalities are in no way linked to physical disabilities.  

      Another problem with this definition is what happens when the majority are abnormal. In America 52% of people have suffered/are suffering from depression but depression is still seen as a mental abnormality. Not being depressed although not being the statistical norm is still considered a normal state. To say that not being depressed is a mental abnormality would completely undermine the whole statistical infrequency idea.

     Despite all of this people still use statistical infrequence to diagnose mental abnormalities. The main reason for this being, it is a very easy, cheap and quick way to see if someone is mentally abnormal. All you need is a couple of graphs. Of course this also raises the problem of whether the data being used is fair representation of the population, dose it take cultural differences into account e.g. a graph of women’s shoe sizes in china would have completely different results to that of the same graph for women in England.

   The other problem that arises from using only a graph to diagnose mental abnormality is; where do you draw the line between abnormal and normal. Is it bang on the median result? Or is it 10 or 20 places either side of that result? Once you have distinguished the difference between normal and abnormal, when does someone become mentally ill? You could go to one doctor and be told you were just abnormal and then go to another one who uses slightly different proportions and be told that you were mentally ill!

     Using statistical infrequencies to distinguish between normal and abnormal is a very mathematical way of diagnosing mental illness. The fact is, people are not as one dimensional as numbers so surely this in not the correct way to diagnose something so serious and life changing. After all a graph can only take into account a couple of pieces of information, whilst our lives are ever more complicated. Surely the view that we can be correctly diagnosed as being abnormal or normal based on two bits of information is frankly ridiculous when there are thousands upon thousands of things ...
