This study provides new longitudinal evidence on two major types of gesture–speech combination that play different roles in children’s early language. We analysed the spontaneous production of 10 Italian children observed monthly from 10–12 to 23–25 months of age. We evaluated the extent to which the developmental trends observed in children’s early gesture–word and word–word productions can predict subsequent verbal abilities. The results indicate that “complementary” and “supplementary” gesture–speech combinations predict subsequent language development in a different manner: While the onset (...) of “supplementary” combinations predicts the onset of two-word combinations, the use of “complementary” combinations at 12 and 18 months predicts the vocabulary and the ability to produce more words utterances at 2 years of age. Moreover, the results suggest that both “complementary” and “supplementary” crossmodal combinations are good predictive indexes of early verbal skills during the second year of age. (shrink)

This study explores the use of deictic gestures, vocalizations and words compared to content-loaded, or representational gestures and words in children’s early one- and two-element utterances. We analyze the spontaneous production of four children, observed longitudinally from 10–12 to 24–25 months of age, focusing on the components of children’s utterances, the information encoded, and the temporal relationship between gestures and vocalizations or words that were produced in combination. Results indicate that while the gestural and vocal modalities are meaningfully and temporally (...) integrated form the earliest stages, deictic and representational elements are unevenly distributed in the gestural vs. the vocal modality, and in one vs. two-element utterances. The findings suggest that while gestural deixis plays a primary role in allowing children to define and articulate their vocal productions, representational skills appear to be markedly more constrained in the gestural as compared to the vocal modality.
