Abstract: 目的:考察两种亚型注意缺陷多动障碍(attention deficit hyperactivity disorder,ADHD)儿童大脑左右半球干扰控制功能的表现.方法:采用跨通道干扰的方式,在儿童的左耳或右耳呈现分心刺激,分别与视觉呈现的靶刺激构成一致、不一致和中性关系.结果:当分心刺激在左耳呈现时,ADHD儿童与正常儿童在错误率上的模式明显不同,ADHD儿童表现出显著的冲突效应(效应量为4%),F(1,110)=18.16,P<0.001,即冲突条件下的错误率明显高于一致条件下的错误率,而正常儿童的冲突效应不显著(效应量为1.2%),F(1,110)=1.59,P>0.1;ADHD儿童的抑制效应呈现翻转趋势(效应量为-1.7%),F(1,110)=3.16,0.05<P<0.1,混合型ADHD儿童的抑制效应翻转显著(效应量为-4.1%),F(1,54)=8.31,P<0.01,即中性条件的错误率高于冲突条件的错误率,正常儿童的抑制效应不显著F(1,110)=1.53,P>0.1.结论:ADHD儿童的右半球控制冲突干扰的功能异常,混合型ADHD儿童右半球的功能异常模式还需进一步研究.
