【摘要】 【目的】探讨Stroop效应在不同亚型注意缺陷多动障碍(attention deficit hyperactivity disorder,ADHD)儿童及对照组儿童的脑反应特征及其差异。【方法】采用1∶1病例对照研究,对6~12岁102例ADHD儿童[注意缺陷型(PI)59例,多动/冲动型(HI)20例,混合型(CT)23例]和102例正常对照组儿童进行Stroop效应测试。【结果】ADHD儿童Stroop效应指标中A、B、C卡片耗时显著高于对照组,B、C卡片正确数显著低于对照组(P<0.05或<0.01);②PI型、CT型ADHD儿童Stroop效应中A、B、C卡片耗时显著高于对照组,B、C卡片正确数显著低于对照组,且PI型、CT型ADHD儿童在B、C卡片耗时显著高于HI型ADHD儿童(P<0.05或<0.01)。【结论】不同亚型ADHD儿童存在明显的信息加工、处理能力不足,执行功能损害,而且各亚型之间的损害程度有所不同。更多还原

【Abstract】 [Objective] To find out response characters and differences of Stroop task among three different subtypes attention deficit hyperactivity disorder(ADHD)and the age-matched normal controls.[Methods] 102 drug-naive ADHD subjects [Predominantly inattentive type(PI):59 cases,Predominantly hyperactive/impulsive type(HI):20 cases,Combined type(CT):23 cases] aged 6 to 12 years were included in this study).All cases of ADHD were diagnosed according to DSM-IV criteria.The Stroop Task was tested for all children.[Results] ①Compared to the normal control group,the ADHD group showed significantly different in the time of reading card A,B,C and reading errors of card B,C(P<0.05 or <0.01).②Compared to every group,PI type and CT type were more in the time of reading card A,B,C and were less in the errors of reading card B,C than the normal control group.And PI type and CT type were more in the time of reading card B,C than HI type(P<0.05 or <0.01).[Conclusions] Children with ADHD have significantly information processing deficiency and executive function impairment,and there are different impairment characters among three different subtypes ADHD.更多还原
