研究综合了包括家长执行的测试和基于网络、电话的多种测试后,对年龄在两岁和十六岁间的儿童进行九次分析。
The results, published in the journal Intelligence, revealed that children from wealthier backgrounds with more opportunities scored higher in IQ tests at the age of two, and experienced greater IQ gains over time.
这项发表于《智力》(Intelligence)杂志的研究结果显示,两岁儿童的家庭经济背景越好,其智商获高分的几率越大,日后的智商增长也更大。
Dr Sophie von Stumm, from Goldsmiths, University of London, who led the study, said: 'We’ve known for some time that children from low socioeconomic status (SES) backgrounds perform on average worse on intelligence tests than children from higher SES backgrounds, but the developmental relationship between intelligence and SES had not been previously shown.
来自伦敦金史密斯大学的索菲·冯·斯蒂姆博士是该研究的负责人,他说:“目前我们的认知是:社会经济地位背景低的孩子,其智力测试结果普遍比家庭背景好的孩子差。但我们还未找到智力和社会经济地位的深层关系。
'Our research establishes that relationship, highlighting the link between SES and IQ.
“我们的研究确认了两者存在联系,突出了社会经济地位和智商二者的关系。
'We hope that our findings will drive future research into the specific mechanisms and factors that underpin the link between SES and IQ and thus, contribute to widening the IQ gap.'
