摘要
对97例智力不同的儿童进行了视觉诱发电位、范畴测验、头发微量元素锌、铜、镉的检测。结果表明,视觉诱发电位可作为儿童脑功能、智力状况的判断指标,特异度和灵敏度分别为92%和72.3%。范畴测验作为传统的思维能力判断指标仍有较好的实用性。本实验检测了头发中微量元素含量,在不同智商的两组儿童中无显著性差异。
Using the techinque of visual evoked potential to judge children
brain functions was primarily studied and compaired with hair trace elements
(Cu,Zn,Cd).The diagnostic criterion consists of P_2,N_2 amplitudes,
apperence of P_3 and the form of main components,The sensitivity of criterion
is 72.3%.The results of category test indicate highly negative related to IQ
(γ=-0.65).This indicated that category test can be used to test the think-
ing development of children,There was no significant difference on hair trace
elements for different IQ children in this paper.
