研究选取了注意缺损多动障碍儿童34名,普通儿童36名,采用选择性注意任务,考察在目标刺激的知觉负荷高低两种情况下,注意缺损多动障碍儿童面对不同干扰程度的分心刺激时,对其的过滤能力是否落后。结果发现,注意缺损多动障碍儿童过滤分心刺激的能力是否落后取决于目标刺激的知觉负荷的高低:(1)在低知觉负荷任务中,不相容分心刺激对两组儿童的干扰程度要大于面对中性分心刺激时受到的干扰。但是注意缺损多动障碍组儿童受到的干扰效应要大于普通组儿童,说明注意缺损多动障碍组儿童过滤分心刺激的能力落后,并出现在注意选择的晚期阶段;(2)在高知觉负荷任务中,所有被试都没有因为分心刺激干扰程度的不同而受到不同的影响,即过滤中性分心刺激与不相容分心刺激的模式一样。
34 children with Attention Deficit Hyperactivity Disorder (ADHD) and 36 children (normal children) were selected to investigate the distraction of children with attention deficit hyperactivity disorder at different levels of distraction When stimulated, its filtering ability is backward. The results showed that attention deficit hyperactivity disorder children filtering distraction ability to lag behind depends on the level of perceptual load of the target stimulus: (1) In the low perceptual load task, the extent of the distraction of incompatible distractions on the two groups of children It is greater than the interference in the face of neutral distractions. However, attention deficit hyperactivity disorder in children received more interference effects than children in the general group, indicating that children with attention deficit hyperactivity disorder filtering ability to distract and appear in the attention of the late stages of selection; (2) in the high perceptual load In the task, all the subjects were not influenced by the degree of distracting stimuli differently, that is, filtering neutral distractions and incompatible distractions.
