But what factors predict the early emergence of these deictic gestures? The present study investigated the longitudinal and cross\u2010sectional influence of caregivers' responsiveness and pointing, beginning at 7\u00a0months, on infants' HoG and index\u2010finger pointing gestures at 10\u00a0months, and infants' language abilities at 24\u00a0months. Utilizing a longitudinal design, we assessed 82 typically developing\n                    <jats:italic>German<\/jats:italic>\n                    infants, 42 of whom were randomly assigned to an intervention group targeted to increase caregivers' responsiveness to their infants' communicative signals and object\u2010directed interactions. We hypothesized that in a process of social co\u2010construction caregivers' responsiveness would enhance infants' gesture and language development. In addition, we examined the hypothesis that infants learn about reference by observing caregivers' initiative pointing gestures, in which case we expected positive associations between caregivers' initiative pointing frequency and infants' communicative development. Group comparisons at 10\u00a0months revealed increased HoG frequency in the responsiveness training group. Pointing frequency or subsequent language skills at 24\u00a0months did not differ between groups. Regression analyses revealed a positive association between caregivers' responsiveness at 10\u00a0months and infants' HoG frequency across groups. Analyses revealed no association between caregivers' initiative pointing and infants' communicative development. A predictive relation between infants' pointing frequency and their subsequent language abilities was confirmed. In support of social constructivist positions, these findings indicate that already infants' early deictic gesture use, specifically their HoGs, is influenced by caregivers' responsiveness.\n                  <\/jats:p>","DOI":"10.1111\/infa.70112","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T04:47:33Z","timestamp":1787028453000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Does Caregivers' Responsiveness Influence the Early Development of Deictic Gestures?
