The relationship between motor control and phonology in dyslexic children.

@article{citeulike:2915251, abstract = {BACKGROUND: The goal of this study was to investigate the automaticity/cerebellar theory of dyslexia. We tested phonological skills and cerebellar function in a group of dyslexic 8-12-year-old children and their matched controls. Tests administered included the Phonological Assessment Battery, postural stability, bead threading, finger to thumb and time estimation. RESULTS: Dyslexic children were found to be significantly poorer than the controls at all tasks but time estimation. About 77\% of dyslexics were more than one standard deviation below controls in phonological ability, and 59\% were similarly impaired in motor skills. However, at least part of the discrepancy in motor skills was due to dyslexic individuals who had additional disorders (ADHD and/or DCD). The absence of evidence for a time estimation deficit also casts doubt on the cerebellar origin of the motor deficiency. About half the dyslexic children didn't have any motor problem, and there was no evidence for a causal relationship between motor skills on the one hand and phonological and reading skills on the other. CONCLUSION: This study provides partial support for the presence of motor problems in dyslexic children, but does not support the hypothesis that a cerebellar dysfunction is the cause of their phonological and reading impairment.}, address = {Institute of Cognitive Neuroscience, University College London, UK. ramus@lscp.ehess.fr}, author = {Ramus, F. and Pidgeon, E. and Frith, U. }, citeulike-article-id = {2915251}, issn = {0021-9630}, journal = {Journal of child psychology and psychiatry, and allied disciplines}, keywords = {cerebellar, dyslexia}, month = {July}, number = {5}, pages = {712--722}, posted-at = {2008-06-22 16:11:51}, priority = {2}, title = {The relationship between motor control and phonology in dyslexic children.}, url = {http://view.ncbi.nlm.nih.gov/pubmed/12831115}, volume = {44}, year = {2003} }
