7～15岁正常儿童脑电α波形及智力、性格关系探究【摘 要】 目的:探讨不同年龄段正常儿童脑电α波形特点与其智力、性格之间的关系。方法:随机对278例、53例共2批7~15岁正常儿童进行脑电图检奄、韦氏儿童智力测量以及艾森客人格问卷(少年)调查。采用SPSS11.0软件系统对比分析α波波形规则程度、相对功率值以及近似熵值与韦氏儿童智力测量表所得各项分数和艾森克人格问卷E、N、P、L维度间的相关关系。结果:278例儿童中:①α波规则程度与IQ总分存在显著性差异,且为正相关;α波规则程度与IQ言语、操作得分及分项目得分均无明显差异。②α波规则程度与艾森克人格问卷中N、E、L二个维度之间存在显著性差异,且与N、E成负相关,与L成正相关;与P无明显著异。53例儿童中:①α波相对功率值、近似熵值随年龄增加而增大。②α波相对功率值、近似熵值与IQ总分、言语、词汇、理解得分之间存在显著性差异,成正相关;与IQ操作得分及分项目得分均无明显相关性。③α波相对功率值、近似熵值与E存在显著性差异,成负相关;α波相对功率值、近似熵值与N、P、L无明显相关差异。结论:①α波规则程度反映儿童大脑发育成熟程度,与智力有明显相关性,但只是反映大脑整体的成熟,与具体脑功能发育无关。②α波相对功率值、近似熵随儿童年龄增加而进行性增大,说明可反映大脑成熟程度及复杂性。③α波相对功率值、近似熵值与性格存住密切关系,性格越成熟、情绪越稳定、办事越沉稳的儿童,α波越成熟、越规则。 【关键词】 α波 智力 性格 近似熵 脑电功率谱 A study on the relationship between normal child brain α wave and child intelligence and character Pang Qiming,et al 【Abstract】 Objective:To study the relationship between normal child brain α wave and intelligence and characters.Then probed how brain α wave can reflect the degree of brain maturity and types of characters.Methods:EEG and marks of intelligence tests and E、N 、 P、L marks of EPQ in 278 normal children were analysed.In the same time,EEG of α wave power spectra、ApEn and marks of intelligence tests,E、N、P、L marks of EPQ in 53 normal children were analysed.Results:In 278 cases,there was significantly positive relationship between EEG regularity and IQ total marks.There was significant relationship between EEG regularity and E、N、L marks of EPQ;There was positive correlation between EEG regularity and L marks,negativecorrelation between EEG regularity and N 、E marks.In 53 cases,α wave power spectra and ApEn were progressively increased while children became older.There was positive correlation between αwave power spectra or ApEn and total IQ marks,marks of words and understandings;There was significantly negative relationship between α wave power spectra or ApEn and E marks of EPQ.Conclusions:The α wave regularity、power spectra and ApEn can suggest the degree of brain maturitv and complexity.And they have si
