Rationale: The purpose of this study was to understand the effects of motor and lexical impairment on communicative gesturing in children with specific language impairment (SLI). This was studied by examining (1) the temporal coordination of speech and gesture and gesture duration in children with and without SLI and (2) the effects of word frequency on these measures.
Methods: Ten children with SLI and 12 typically developing children produced a narrative. Gesture-speech pairs were identified and coded for synchrony between gesture and speech onset (gesture-speech coordination, GSC) and gesture duration (GD).
Results: No significant group differences were found for GSC or GD. Both measures were significantly affected by word frequency, but not significantly different between the two groups.
Conclusions: Children with SLI produce communicative gestures that are temporally well synchronized with their speech, suggesting that gestures are not affected by motor and lexical deficits. This finding contributes to literature hypothesizing that manual communicative gesturing is an area of strength in SLI.
