不同亚型ADHD儿童的视通道时距估计能力

本研究选取ADHD混合型儿童11名,ADHD注意缺损型儿童13名以及正常儿童15名,通过"平均估计长度"、"平均估计误差百分比"、"估计变异值"三个指标,考察不同亚型ADHD儿童在时距复制和言语估计上的稳定性和精确性。研究发现,在视觉刺激条件下,ADHD儿童的时距估计缺损并不受时距长度的影响;ADHD混合型儿童在多项任务中所表现的稳定性和精确性都差,而ADHD缺损型儿童只是稳定性差,说明ADHD混合型是ADHD中更严重的亚类型;ADHD儿童在时距估计任务中稳定性差,反映了其状态调节能力的落后。

Visual Temporal Estimation Ability In Different Subtypes of Children With ADHD

By testing 39 primary school students (13 ADHD-C,11 ADHD-I and 15 mental normal children) with the target time of 2s、 15s and 45s on visual temporal estimation,the results showed that: (1) the deficit of ADHD on temporal estimation won't be affected by length of intervals; (2) the ADHD-I only showed specific deficit in stability,while the ADHD-C showed deficit both in stability and accuracy.We suggest that the deficit of ADHD on temporal estimation stability showed their deficit on state regulation.
