Document Summary

The first two or three years set the pace for language and cognitive development during the rest of childhood and can affect adult abilities. The most important predictor of ultimate language attainment is the amount of time the infant spends in social exchanges with caregivers and other older family members. It is estimated that 2-19 percent of children experience early language difficulties. Less is more hypothesis the proposal that working memory constraints help infants focus on the relevant cues to segmenting the speech stream. At four months of age, infants mainly look at the caregiver"s eyes but in the following months they shift their attention more toward the mouth only to shift back to the eyes sometime after their first birthday. Infant directed speech is generally appealing to babies. As infants begin to recognize stretches of the speech stream as recurring sequences, they develop abstract representations of these word forms.
