Language learning begins with listening.
Children are greatly different in the amount of listening they do before they
start speaking, and later starters are often long listeners. Most children will
“obey” spoken instructions some time before they can speak, though the word
“obey” is hardly accurate as a description of the eager and delighted
cooperation usually shown by the children. Before they can speak, many children
will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from
the noises babies make to their first spoken words leads to considerable
difficulties. It is agreed that they enjoy making noises, and that during the
first few months one or two noises sort themselves as particularly expressive
as delight, pain, friendliness, and so on. But since these can’t be said to
show the baby’s intention to communicate, they can hardly be regarded as early
forms of language. It is agreed, too, that from about three months they play
with sounds for enjoyment, and that by six months they are able to add new words
to their store. This self-imitation(模仿) leads on to deliberate(有意的) imitation of sounds made or words spoken to them by other people.
The problem then arises as to the point at which one can say that these
imitations can be considered as speech.
It is a problem we need to get our teeth
into. The meaning of a word depends on what a particular person means by it in
a particular situation; and it is clear that what a child means by a word will
change as he gains more experience of the world. Thus the use, at seven months,
of “mama” as a greeting for his mother cannot be dismissed as a meaning-less
sound simply because he also uses it at another time for his father, his dog,
or anything else he likes. Playful and meaningless imitation of what other
people say continues after the child has begun to speak for himself. I doubt,
however, whether anything is gained when parents take advantage of this ability
in an attempt to teach new sounds.
