Passage 2
Intelligence: a changed view
1£®Intelligence was believed to be a fixed entity£¬some faculty of the mind that we all possess and which determines in some way the extent of our achievements£®Its Value 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 children according 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 has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself£®There is considerable evidence now which shows the great 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 fortunate classmates£®
3£®There are evidences that support the view that we have to distinguish between genetic intelligence and observed intelligence£®Any deficiency in the appropriate genes will restrict development no matter how stimulating the environment£®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£®
