目的:探讨注意缺陷多动障碍(ADHD)儿童的抑制控制和转换功能。方法:采用图形选择测验、威斯康星卡片分类测验(WCST)、昼夜Stroop测验和字色Stroop测验,以23例ADHD儿童和22例普通对照儿童为研究对象,对其抑制控制能力、转换能力进行测试比较。结果:1.ADHD儿童完成图形选择测验转换任务时间较普通对照组儿童明显延长,犯错误数明显增多;2.ADHD儿童完成威斯康星卡片分类测验的错误应答数、持续性错误数明显比普通儿童多,差异极其显著;3.两组儿童完成昼夜Stroop测验时冲突任务平均时上有显著性差异,ADHD儿童的反应时多于普通儿童;4.ADHD儿童完成字色Stroop测验的干扰任务反应时较普通对照组儿童显著延长。结论:ADHD儿童的抑制控制能力和转换能力显著低于普通儿童。
Objective: To investigate the inhibitory control and conversion of children with attention deficit hyperactivity disorder (ADHD). Methods: Twenty-three children with ADHD and 22 children with normal control were studied by graph selection test, Wisconsin Card Sorting Test (WCST), day and night Stroop test and character Stroop test, and their inhibition and control ability were tested and compared . ADHD children completed the task of graphics selection test conversion task significantly longer than the average control group children, making mistakes significantly increased; 2. ADHD children to complete the Wisconsin card classification test error response number, the number of persistent errors significantly more than the average child , The difference was extremely significant; 3. When the two groups of children finished the day and night Stroop test, the conflict task averaged significant difference, ADHD children responded more than normal children; 4. ADHD children completed the character Stroop test interference task response Children in the normal control group were significantly prolonged. Conclusion: Children with ADHD have significantly lower inhibitory control and conversion ability than ordinary children.
