Intelligence: a Changed View1． Intelligence was believed to be a fixed entity (存在, 实体), some faculty of the mind that we all possess and which determines in some way the extent of our achievements． Itsvalue, therefore, was as a predictor of children's future learning． If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious． Intelligence tests could be used for streaming (分流, 分组) childrenaccording to ability at an early age; and at 11 these tests were superior to measures of attainment for selecting children for different types of secondary education．
2． Today, we are beginning to think differently． In the last few years, research hasthrown doubt on the view that innate 内在的) intelligence can ever be measured and onthe very nature of inelligence itself． There is considerable evidence now that shows thegreat influence of environment both on achievement and intelligence． Children with poor home backgrounds not only do less well in their school work and intelligence tests but their performance tends to deteriorate gradually compared with that of their more fortunateclassmates．
3． There are evidences that support the view that we have to distinguish between genetic intelligence and observed intelligence (习得智力)． Any deficiency in the appropriate genes will restrict development no matter how stimulating the environment is． We cannot observe and measure innate intelligence, whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment． Researches have been investigating what happens in this interaction(相互作用)．
4． Two major findings have emerged from these researches． Firstly, the greater part of the development of observed intelligence occurs in the earliest years of life． It is estimated that 50 per cent of measurable intelligence at age 17 is already predictable by the age of four． Secondly, the most important factors in the environment are language and psychological aspects of the parent-child relationship． Much of the difference in measured intelligence between “privileged” and “disadvantaged” children may be due to the latter’s lack ofappropriate verbal stimulation and the poverty of their perceptual (感性的) experiences．
5． These research findings have led to a revision in our understanding of the nature of intelligence． Instead of it being some largely inherited fixed power of the mind, we now see it as a set of developed skills with which a person copes with any environment． Theseskills have to be learned and, indeed, one of them is learning how to learn．
6． The modern ideas concerning the nature of intelligence are bound to have someeffect on our school system． In one respect a change is already occurring． With the mo
