Is language, like food, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick I 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. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by Frederick。 Nevertheless, some children are still backward in speaking。 Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly。 If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again。 A bird learns to sing and to fly rapidly at right time, but the process is slow and hard once the critical stage has passed。
Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ。 At twelve weeks a baby smiles and makes bowel – 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 born with the capacity to speak。 What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to commect the sight and feel of, say, a toy – bear with the sound pattern “toy – bear”。 And even more incredible is the young brain’s ability to pick out an order in language from the mixture of sound around him, to analyse, to combine and recombine the parts of a language in new ways。
But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child’s babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals,. Sensitivity to the child’s non – verbal signals is essential to the growth and development of language.

Racket, din clamor, noise, whatever you want to call it, unwanted sound is America’s most widespread nuisance。 But noise is more than just a nuisance。 It constitutes a real and present danger to people’s health。 Day and night, at home, at work, and at play, noise can produce serious physical and psychological stress。 No one is immune to this stress。 Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds—sometimes with extreme tension, as to a strange sound in the night。
The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside us。 Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement programs。 The more subtle and more serious health hazards associated with stress caused by noise traditionally have been given much less attention。 Nevertheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair warning that other thing may be happening to us, some of which may be damaging to our health。
Of many health hazards to noise, hearing loss is the most clearly observable and measurable by health professionals. The other hazards are harder to pin down. For many of us, there may be a risk that exposure to the stress of noise increases susceptibility to disease and infection. The more susceptible among us may experience noise as a complicating factor in heart problems and other diseases. Noise that causes annoyance and irritability in health persons may have serious consequences for these already ill in mind or body.
Noise affects us throughout our lives. For example, there are indications of effects on the unborn child when mothers are exposed to industrial and environmental noise. During infancy and childhood, youngsters exposed to high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.
Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise and many disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend to dismiss annoyance as a price to pay for living in the modern world. It may also be because we still think of hearing loss as only an occupational hazard.
