Language, the organization of thought and social communication in boys and girls with an extra X chromosome
The presence of an extra X chromosome may profoundly affect cognitive and behavioural development, although to a variable degree. Language difficulties are typically found in boys with an extra X chromosome. Although many studies have reported specific language dysfunctions, the consequences of these impairments in terms of social development and risk for psychopathology, have received very little attention. Also, it has remained unclear to what degree girls with an extra X chromosome (Triple X syndrome) have a similar cognitive and behavioural phenotype as boys with an extra X chromosome (Klinefelter syndrome).
This project focuses on the role of language in the organization of thought and the effect of dysfunctions in these areas on social communication skills and risk for psychopathology. We investigate this in boys as well as girls with an extra X chromosome.
