"The Simple Reason Some Kids Learn to Talk Earlier"
Originally Published 1 year ago — by ScienceAlert
A recent observational study involving over 1,000 children under the age of four found that the amount of adult talk a child hears is strongly linked to their own speech development, regardless of gender, socioeconomic status, or exposure to multiple languages. The study, conducted across 12 countries and 43 languages, used wearable recorders to collect over 40,000 hours of recordings and found that for every 100 adult vocalizations heard by a child within an hour, the child produced 27 more vocalizations. This suggests that promoting more adult talk around children may prove beneficial for their language development. However, the study's coarse-grained approach may have overlooked some finer details, and further research is needed to understand the intricacies of language development in children.
