Questions 10-20Long before they can actually speak, babies pay special attention to the speech theyhear around them. Within the first month of their lives, babies' responses to the sound ofthe human voice will be different from their responses to other sorts of auditory stimuli.Line They will stop crying when they hear a person talking, but not if they hear a bell or the(5) sound of a rattle. At first, the sounds that an infant notices might be only those words thatreceive the heaviest emphasis and that often occur at the ends of utterances. By the timethey are six or seven weeks old, babies can detect the difference between syllablespronounced with rising and falling inflections. Very soon, these differences in adult stressand intonation can influence babies' emotional states and behavior. Long before they(10) develop actual language comprehension, babies can sense when an adult is playful orangry, attempting to initiate or terminate new behavior, and so on, merely on the basis ofcues such as the rate, volume, and melody of adult speech.Adults make it as easy as they can for babies to pick up a language by exaggeratingsuch cues. One researcher observed babies and their mothers in six diverse cultures and(15) found that, in all six languages, the mothers used simplified syntax, short utterances andnonsense sounds, and transformed certain sounds into baby talk. Other investigators havenoted that when mothers talk to babies who are only a few months old, they exaggeratethe pitch, loudness, and intensity of their words. They also exaggerate their facialexpressions, hold vowels longer, and emphasize certain words.(20) More significant for language development than their response to general intonation isobservation that tiny babies can make relatively fine distinctions between speech sounds.other words, babies enter the world with the ability to make precisely those perceptualdiscriminations that are necessary if they are to acquire aural language.Babies obviously derive pleasure from sound input, too: even as young as nine months(25) they will listen to songs or stories, although the words themselves are beyond theirunderstanding. For babies, language is a sensory-motor delight rather than the route toprosaic meaning that it often is for adults.
