ABSTRACT

Twenty six empirical investigations have now established that children and adults with DSM-defined Attention deficit/Hyperactivity disorder (ADHD) of the Hyperactive type (ADHD-H) or, more commonly, Combined Hyperactive/Inattentive types (ADHD-C) manifest a small but significant visual attentional bias to the right side (left subclinical neglect), consistently suggesting the existence of a subtle right hemisphere dysfunction or hemispheric imbalance in hyperactive people. Only one research team has investigated and compared the DSM-defined Inattentive subtype (ADHD-I) to the Hyperactive subtype (ADHD-H), confirming that line bisection is biased to the right in ADHD-H and discovering that it is biased to the left in ADHD-I. We aimed to test whether a similar crossed double dissociation would extend to Rey’s Complex Figure Copy Task (RCF-CT), a simple visuospatial-constructive task. Clinical files of 205 juvenile clients from 6 to 16 years of age from a neuropsychological private clinic specialized in ADHD were analysed. Extreme scores on the Connors-3 Hyperactivity vs Inattention Parent Rating scales associated, respectively, with significant rightward and significant leftward emplacement of the drawing on the page on the RCF-CT. These results replicate previous findings and extend the “energetics” model of hemispheric specialization.

摘要

26 项实证调查现已确定，患有 DSM 定义的注意力缺陷/多动障碍 (ADHD) 的多动型 (ADHD-H) 或更常见的多动/注意力不集中型 (ADHD-C) 的儿童和成人表现出小但明显的视觉注意力偏向右侧（左侧亚临床忽视），始终表明过度活跃的人存在细微的右半球功能障碍或半球失衡。只有一个研究团队调查并比较了 DSM 定义的注意力不集中亚型 (ADHD-I) 与多动亚型 (ADHD-H)，确认线平分在 ADHD-H 中偏向右侧，并发现它偏向于留在 ADHD-I 中。我们旨在测试类似的交叉双解离是否会扩展到 Rey 的复杂图形复制任务 (RCF-CT)，一个简单的视觉空间建设任务。分析了来自专门从事 ADHD 的神经心理学私人诊所的 205 名 6 至 16 岁青少年客户的临床档案。Connors-3 多动症与注意力不集中的父母评分量表的极端得分分别与 RCF-CT 页面上绘图的显着向右和显着向左放置相关。这些结果复制了先前的发现并扩展了半球专业化的“能量学”模型。RCF-CT 页面上的绘图显着向右和显着向左放置。这些结果复制了先前的发现并扩展了半球专业化的“能量学”模型。RCF-CT 页面上的绘图显着向右和显着向左放置。这些结果复制了先前的发现并扩展了半球专业化的“能量学”模型。
