中国科学院心理研究所茅于燕同志,用三年时间对二十九个婴幼儿智力发展作了追踪研究,获取了大量的第一手资料。茅于燕同志将其中的三个问题撰写了三篇文章,以助于广大家长科学地育儿。我们觉得这种做法值得提倡,希望更多的专家将自己的研究成果贡献给渴求科学育儿知识的中青年父母们。 Comrade Mao Yuyan, Institute of Psychology, Chinese Academy of Sciences, made a follow-up study on the intelligence development of 29 infants and young children in three years and obtained a large amount of first-hand information. Comrade Mao Yuyan wrote three articles on three of these issues to help the majority of parents scientifically raise their children. We think this approach deserves promotion. We hope that more experts will contribute their research results to young and middle-aged parents who crave scientific parenting knowledge.
