Narrative Abilities at Age 3 Are Associated Positively With Gesture Accuracy but Negatively With Gesture Rate

Abstract

Purpose: Though the frequency of gesture use by infants has been related to the development of different language abilities in the initial stages of language acquisition, less is known about whether this frequency (or “gesture rate”) continues to correlate with language measures in later stages of language acquisition, or whether the relation to language skills also depends on the accuracy with which such gestures are produced (or reproduced). This study sets out to explore whether preschoolers' narrative abilities are related to these two variables, namely, gesture rate and gesture accuracy. Method: A total of 31 typically developing 3- to 4-year-old children participated in a multimodal imitation task, a context-based gesture elicitation task, and a narrative retelling task. Results: Results showed that there was a significant positive correlation between the children's narrative scores and their gesture accuracy scores, whereas higher rates of gesture use did not correlate with higher levels of narrative skill. Further multimodal regression analysis confirmed that gesture accuracy was a positive predictor of narrative performance, and moreover, showed that gesture rate was a negative predictor. Conclusions: The fact that both gesture accuracy and gesture rate are strongly and differently linked to oral language abilities supports the claim that language and gesture are highly complex systems, and that complementary measures of gesture performance can help us assess with greater granularity the relationship between gesture and language development. These findings highlight the need to use gesture during clinical assessments as an informative indicator of language development and suggest that future research should further investigate the value of multimodal programs in the treatment of language and communication disorders.
