测定儿童智力的传统方法是使用智力测验。智力水平的高低用智商(IQ)表示。传统的智力测验计算智商的公式是:智商=心理年龄/实足年龄×100。例如,一个10岁的儿童能顺利地通过测表中10岁年龄组的试题(但不能通过11岁年龄组的题目),那么他的心理年龄就等于10岁。运用以上公式(IQ=10/10×100),便可求得他的智商为100。另一名10岁儿童能成功地通过13岁年龄组的试题,则他的心理年龄为13岁,所求得的智商是130。通常,把智商在90～110之间(平均数为100)的人称为“中等智力”的正常人,这
The traditional method of measuring children’s intelligence is to use intelligence tests. The level of intelligence with IQ (IQ) said. The traditional IQ test formula is IQ: IQ = mental age / full age × 100. For example, a 10-year-old can successfully pass the 10-year-old test (but can not pass the 11-year-old test), and his mental age is equal to 10. Using the above formula (IQ = 10/10 × 100), we can find his IQ of 100. Another 10-year-old could successfully pass the 13-year-old test, and his psychological age was 13 and his IQ was 130. Normally, a person who has an IQ between 90 and 110 (an average of 100) is referred to as a normal person with “moderate intelligence”
