In infancy and early childhood, the right hemisphere is more active and dominant, and children naturally communicate through body language, music, rhythm, and imitation games, and this capacity for embodied, playful communication is the foundation of human connection before language develops.

Babies learn language through interaction with their caretakers (mothers and primary caregivers), making this dyadic interaction the fundamental mechanism of language acquisition.

The 'Still Face Experiment' from the Harvard Child Development Center demonstrates that babies are hard-wired to engage with caregivers and respond negatively when that engagement is withheld, progressing from attempts to elicit response, to frustration, to hopeless crying.

At the end of three years, babies born to welfare parents had learned 500 words, while babies in professional families knew over 1,000 words—a doubling of vocabulary that corresponds to the 30 million word exposure gap.

Language learning requires interactive engagement with a caregiver; babies placed in front of televisions do not learn language even if they hear words, because it is the interaction—not merely hearing—that is essential.

Very young children, as young as three or four years old, already demonstrate teaching or pedagogical intelligence, as evidenced by the fact that they explain things differently depending on whether they are teaching a younger person (with details, pointing, and slow speech) versus an older person (with elliptical, abbreviated explanations).

Children under nine show the highest sensitivity to being stared at, suggesting it is a deeply rooted biological capacity that may decline with age as conscious rational thinking overrides intuitive sensing.
