The impact of maternal gaze responsiveness on infants' gaze following and later vocabulary development.

Research has shown that infants' language development is influenced by their gaze following-an ability linked to their cognitive and social development. Following social learning approaches, this pilot study explored whether variations in gaze following and later vocabulary scores relate to early mother-infant interactions by focusing on the role of mothers' gaze responsiveness in infants' attentional and language development. We recruited 15 mother-child pairs in Poland and assessed their engagement in joint attention episodes. Results indicate that mothers foster their infants' gaze-following ability by providing them with numerous opportunities to participate in the task. We also confirmed a correlation between infants' gaze-following ability at 6 months and their vocabulary scores at 24 months. However, combining both infants' gaze following and mothers' gaze monitoring as predictors in one model revealed that maternal gaze monitoring was a stronger predictor of infants' later vocabulary growth. Overall, this study emphasizes that mothers' gaze responsiveness is a crucial feature of scaffolding that impacts on infants' gaze following and language development.
