What happened to the child in Frederick’s experiment?
Is language a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the experiment of Frederick in the thirteenth century it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the infants died before the first year.
Today no such drastic deprivation exists. Nevertheless, some children are still backward in speaking. Most often the reason is that the mother is insensitive to the signals of the infant. There are critical times when children learn more readily. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again.
Linguists suggest that speech milestone is reached in a fixed sequence and at a constant age. At twelve weeks a baby smiles and utters vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1,000 words which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar.
Recent evidence suggests that an infant is born with the capacity to speak. What is special about man’s brain is the complex system which enables a child to connect the sight and feel. And even more incredible is the young brain’s to pick out an order in language from the hubbub of sound around him, to analyze, to combine and recombine the parts of a language in novels.
But speech has to be triggered, and this depends on interaction between the mother and child. Insensitivity of the mother dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s non-verbal cues is essential to the growth and development of language.
选项
A、Their brains have been input with too much language at once.
B、They do not listen carefully to their mothers.
C、Their mothers are not intelligent enough to help them.
D、Their mothers do not respond to their attempts to speak.
答案
D
解析
本题为细节题。从句子“Nevertheless, some children are still backward in speaking. Most often the reason is that the mother is insensitive to the signals of the infant”可知,如果母婴之间语言互动交流太少,婴儿的语言能力就会发展迟缓。因此选D。
