    • research into atypical sex chromosome syndromes has made contributions to the nature-nurture debate
    • by comparing people who have these syndromes with chromosome typical individuals it becomes possible to see psychological and behavioural differences between the two groups
    • it might be logically inferred that these differences have a biological basis and are a direct result of the abormal chromosomal structure
    • the relationship between the atypical chromosomal patterns associated with Klinefelter’s and Turner’s syndrome and the differences in behaviour seen in this individuals is not causal
    • it may be that environmental and social influences are more responsible for the behavioural differences observed
    • social immaturity seen in females with Turner’s syndrome may arise from the fact that they are treated immaturely by the people around them
    • parents, teachers and others may react to the prepubescent appearance of people with Turner’s in a way that encourages immature behaviour and this may have a direct impact upon their performance at school
    • continued research into atypical sex chromosome patterns is likely to lead to earlier and more accurate diagnosis as well as more positive outcomes in the future
    • an australian study of 87 individuals with Klinefelter’s syndrome showed that those who had been identified and treated from a very young age experienced significant benefits in terms of managing their syndrome
    • in order to identify the characteristics of XXY individuals it is necessary to identify a large number of individuals with the disorder and build a database so we can see the full range of characteristics
    • in general only those people who have the most severe symptoms are identified and therefore the picture of typical symptoms may be distorted
    • Boada et al report that prospective studies have produced a more accurate picture of the characteristics
    • many individuals with Klinefelter’s do not experience significant cognitive or psychological problems and many are highly successfully academically
