To Talk

The process of learning language begins long before birth, as fetuses experience sounds within the womb. By 24 weeks, the inner ear is developed, allowing them to hear the mother's heartbeat and external sounds, especially her voice. Research shows that a mother's voice makes the fetus's heart beat faster, initiating communication and laying the groundwork for language familiarity.

Newborns are ready to communicate, primarily through crying, which elicits immediate responses and teaches them about communication. Even a 12-hour-old infant prefers their native language's rhythms. Six-week-old Rebecca demonstrates responsiveness to her mother's voice, highlighting babies' innate ability to distinguish speech sounds. Dr. Reva Shi's experiment reveals that even at birth, babies can distinguish words that convey meaning (nouns and verbs) from prepositions and articles.

By three months, babies like Phoenix vocalize more, with conversation developing through facial expressions, gaze, and mirrored interactions. Dr. Darwin Muir's experiments show that babies, as young as five months, interpret direct communication, emotional congruence between voice and face, and eye gaze as crucial for interaction, getting upset if these signals are disrupted.

Babies are born "universal linguists," capable of distinguishing all language sounds. However, between 6 and 10 months, their brains begin to filter out sounds not present in their native language, becoming "culture-bound language specialists." Studies by Pat Kuhl show that exposure to a second language like Mandarin during this sensitive period can maintain their ability to discriminate those new sounds. The unique cadence of "motherese" aids in acoustic mapping and early word learning.

Babbling, initially universal, narrows to native language sounds by nine months, serving as practice for speech. Gestures, especially pointing, signify a significant mental leap, as infants understand the connection between the pointer and the object. Dr. Amanda Woodward's research shows that learning new words requires both following pointing and the speaker's gaze. Imitation is a primary learning engine, demonstrated by Dr. Andrew Meltzoff's experiments where toddlers mimic actions and understand turn-taking, forming the basis of communication.

After age one, babies transition from sounds to words, acquiring 50-100 active words by 18 months and understanding many more. Common first words often include nouns and universal terms like 'all gone' and 'uh oh.' A "language explosion" occurs between 18 months and 2 years, as children grasp that everything has a name. Research indicates that focusing on shape is crucial for rapid word learning. By two years, children typically use over 300 words and understand about a thousand, their inner world becoming visible through speech and play.
