This work is a first exploration of the temporal relationship existing in 1 ges-ture/ 1 word utterances, produced in crossmodal combination (with semantic relation), distinguished between "synchronous" or "asynchronous" combina-tions in the spontaneous production of 10 single full-term and 2 preterm chil-dren without neurological damage, during the second year of life. We collected, for each child, spontaneous productions in interaction with their mothers through video recordings on a monthly basis, from 10-12 to 23-25 months of age, in accordance with the standard methodology used in studies on the collec-tion and analysis of spontaneous production. In full-term children with typical development synchronous crossmodal combinations that prevail over asyn-chronous combinations, proving that they know how to co-articulate gesture and speech both on the semantic and temporal planes. Data on preterm chil-dren suggest an initial prevalence of use of asynchronous combinations, and a developmental risk in these children. The use of a non coarticulation multimod-al communication in the first development could affect next acquisitions. The results of this study represent a confirmation with respect to evidence of dis-harmonious development profiles among preterm children without neurological damage, since the first acquisitions.
