【摘要】：工作记忆缺陷是ADHD理论的一大重要假设，然而很少有研究将重点放在ADHD儿童的视觉空间工作记忆上。本研究采用组群研究的方法，，通过使用九宫格方式，操纵不同干扰类型，以考察不同类型的干扰对ADHD儿童视觉空间工作记忆的不同阶段的影响。本研究包括两个实验。实验1是采用一致性判断任务，考察ADHD儿童在编码阶段的视觉空间工作记忆特点，结果表明，在有干扰的情况下，ADHD儿童在编码阶段的成绩显著落后于正常儿童，而在无干扰情况下，两组被试不存在显著差异。实验2是采用再认任务，考察ADHD儿童在保持阶段的视觉空间工作记忆特点，实验表明在保持效应量上，ADHD儿童与正常儿童之间差异不显著。根据实验结果和分析，本研究主要得到以下几个结论：1）ADHD儿童在视觉空间工作记忆方面不存在缺陷。2)客体干扰对ADHD儿童影响较大，即在有干扰情况下ADHD组儿童的成绩显著落后于对照组。
[Abstract]:Working memory impairment is an important hypothesis in ADHD theory. However, few studies have focused on the visual spatial working memory of ADHD children. In order to investigate the effects of different types of interference on the working memory of visual space in children with ADHD, a cluster method was used to manipulate different types of interference. This study includes two experiments. In experiment 1 the visual spatial working memory characteristics of ADHD children in coding stage were investigated by using consistency judgment task. The results showed that the scores of ADHD children in coding stage were significantly lower than that of normal children in the case of interference. Without interference, there was no significant difference between the two groups. In experiment 2, recognition tasks were used to investigate the visual spatial working memory characteristics of ADHD children during the retention phase. The results showed that there was no significant difference between the retention effect of ADHD children and normal children. Based on the experimental results and analysis, the following conclusions are obtained: 1) there is no defect. 2) object interference has a great influence on ADHD children. The results of ADHD group were significantly lower than that of control group.
