It is often assumed that boys and girls with more severe motor difficulties are more likely to have cerebral dysfunction and thus more problems with neuropsychological functioning. In order to explore this issue we examined the responses of a cohort of 10 year-old boys and girls with low and very low motor proficiency levels on written and oral forms of the Symbol Digit Modalities Test (SDMT). This test is used to assess neuropsychological functions including attention, impaired visual scanning, visual-perceptual ability and speed of motor processing.
