The development of speech in human children is a lengthy process influenced by social interactions. From infancy, infants emit vocalizations in the company of others, providing valuable feedback on effective communication techniques. However, for feedback to materialize, children's speech must induce alterations in the brains of their caregivers.
Researchers employed dual-brain functional near-infrared spectroscopy (fNIRS) to observe real-time communication between caregivers and their 2- to 3-year-old children (n = 56). The study revealed that children's vocalizations selectively influenced caregivers' brain activity. Specifically, parents' brains exhibited a swift response to children's production of speech that was more advanced than their babbling.
This implies that an essential aspect of learning to talk involves understanding how to elicit one's communication partner's attention. Consequently, early conversations likely offer continuous opportunities for feedback, guiding children toward advancements in spoken language.
