应用《瑞文测验》对哈尔滨市市区1410名小学生进行了智力调查。结果表明,儿童平均智商水平为101.51±14.42,智商呈正态分布,证明从整体上说哈尔滨市学龄儿童的智力发育基本上是正常的。但其中太平区儿童智商较低(89.72±14.30),明显低于其它各区,并低于本智力量表的常模;智商分布向中下水平偏移;在被测试的142名儿童中,智力落后者(IQ≤69)发生率为8.5％,明显高于其它各区;其中未发现智力优秀(IQ120～129)和超优(IQ≥130)者。提示太平区儿童的智力发育受到一定损伤,该区儿童可能存在一定程度的碘缺乏。
The “Raven Test” was used to investigate the intelligence of 1410 primary school students in downtown of Harbin.
