The linguistic and writing performance of children with Developmental Dyslexia, with and without handwriting problems (dysgraphia), were compared to that of children with Typical Development. The quantitative kinematic variables of handwriting were collected by means of a digitizing tablet. The results showed that all children with Developmental Dyslexia wrote more slowly than those with Typical Development. Contrary to typically developing children, they also varied more in the time taken to write the individual letters of a word and failed to comply with the principles of isochrony and homothety. Moreover, a series of correlations was found among reading, language measures and writing measures suggesting that the two abilities may be linked. We propose that the link between handwriting and reading/language deficits is mediated by rhythm, as bot...

Some researchers have suggested that children with bilateral perisylvian polymicrogyria mentally fail to reach the syntactic phase and do not acquire a productive morphology. This patient achieved a mean length of utterance in signs/gestures of 3.4, a syntactic phase of completion of the nuclear sentence and the use of morphological modifications. We discuss the link between gesture and language and formulate hypotheses on the role of gestural input on the reorganization of compensatory synaptic circuits.
