A tale of four hands: How mother-child dyadic visuo-manual exploration of the physical world supports language development in preterm and full-term children at 24 months.

This thesis explores how mother–child visuo-manual exploration at 24 months—through shared interaction with objects—supports language development, focusing on differences between preterm and full-term children. Using head-mounted cameras and observational methods, the study highlights the crucial role of caregiver responsiveness and object manipulation in fostering effective language learning moments.
