智力发展水平的研究即是一个重要的理论课题又有十分广泛的实际意义。国内以前研究较少,近年来我国先后引进多种量表,但均有不足之处。如Gesell量表只适用于3岁以内小儿,DDST量表仅可为智能定性,而Wechsler量表引进后首先在上海地区进行标准化及效度检验,查测结果相关系数较高,效度满意。 The study of the level of intellectual development is an important theoretical issue and has a very wide range of practical significance. In the past, there were few studies in China. In recent years, our country has introduced many kinds of scales successively, but all have shortcomings. For example, the Gesell scale is only suitable for children under three years of age. The DDST scale can only be qualitatively intelligent. The Wechsler scale was first standardized and validated in Shanghai. The correlation coefficient of the test results was high and the validity was satisfactory.
