【摘要】：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。
[Abstract]:In this study, 34 children with attention deficit hyperactivity disorder (ADHD) and 36 normal children were selected. The task of selective attention was used to investigate the perception load of target stimulation. Attention deficit hyperactivity disorder children with different levels of distraction stimulation, their filtering ability lag behind. The results showed that the ability of children with attention deficit hyperactivity disorder (ADHD) to filter distraction stimuli was backward or not depending on the perceived load of the target stimulus: (1) in the task of low perceptual load, The interference of incompatible distraction stimulation was greater than that of neutral distraction stimulation in both groups. But the children in ADHD group were more disturbed than those in normal group, which indicated that the ability of distraction stimulation in ADHD group was backward and appeared in the late stage of attention selection. (2) in the task of high perception load, all subjects were not affected by the different degree of distraction, that is, filtering neutral distraction stimulation and incompatible distraction stimulation were the same.
