Researchers are increasingly interested in manipulating the environment early in children’s lives when they are perceived to be at risk for impoverished intelligence. In a program conducted in North Carolina by Craig Ramey and his associates, pregnant women with IQs averaging 80 were recruited for a study. After their babies were born, half of the infants were cared for during the day at an educational day-care centre and half were reared at home by their mothers. Both groups of children were given medical care and dietary supplements, and their families were given social services if they requested them.
At the age of 3, the children who attended the educational day-care centre had significantly higher IQs than did the home-reared children. This difference was likely due to the decline in the IQs of the home-reared children during the period from 12 to 18 months of age. By the time the children were 5 years old, 39percent of the home-reared children had IQs below 85 but only 11 percent of the educational day-care children had IQs this low. In the most recent evaluation of this project, positive effects of educational day-care on the intellectual development and academic achievement of the children were evident at age 12.
Some parents, such as those in Ramey’s study, have difficulty providing an adequate environment for the intellectual needs of their infants. Once these difficulties are a recurring part of the family system, changing efforts probably will be more difficult and costly. Early intervention in the family system is directed at changing parental adaptive and responsive functioning so that permanent negative effects are minimized.
In another investigation, the Infant Health and Development(IHD)Program, early intervention with low birth weight children revealed that both home visitation(探望)and an educational child curriculum improved the children’s IQs, decreased behaviour problems, and improved the home environment. The intervention was more effective with mothers with low educational attainment than those with high educational attainment, more effective for African-American than White children, and effective for most at-risk children.
Intervention programs have the most positive effects on children’s well-being when they(A)begin as early as possible,(B)provide services to parents as well as to the children,(C)have a low child-teacher ratio,(D)have high parental involvement, and(E)have frequent contacts. In one review of family intervention studies, intervention was more effective when there were eleven or more contacts between the intervener and the family. While eleven sessions is a somewhat arbitrary number, it does indicate that a certain duration of contact is necessary for intervention success. [br] It is implied in the passage that the babies at the day-care centre______.
选项
A、were bom of mothers with higher IQs
B、were more closely attended to by their mothers
C、were reared under a more favourable environment
D、were given more medical care than those at home
答案
C
解析
根据题干中的children和day-care centre可将本题出处定位于第2段首句。该段首句提到,在day—care centre抚养的孩子的智商比在家里抚养的孩子的智商要高,而第3段首句说有的家长不能在家提供能满足孩子智力发展需要的环境,由此可知,相对于家里,日托所对于孩子智力发育更有好处,故答案为C)。文章首段提到,这两类孩子都被给予了同样的医疗照顾,妈妈的智商都差不多(平均为80),因此A)、D)均错误。B)在文中未提及。
