【摘要】：采用Posner的内源性和外源性线索实验范式,材料为1~9的阿拉伯数字(不包括5),以判断目标数字是否大于5为任务,考察视觉选择性注意中的内源性注意和外源性注意对注意缺陷型多动障碍儿童(ADHD)数字加工距离效应的影响。结果发现:(1)内源性和外源性注意条件下,正常儿童在数字判断加工任务中的反应时短于ADHD儿童;(2)内源性有效线索提示条件下,ADHD儿童和正常儿童均表现出显著的数字距离效应;而无效线索提示条件下,ADHD儿童的大小数字距离效应均不明显,正常儿童仍然表现出显著的数字距离效应;(3)外源性有效线索提示条件下,ADHD儿童的小数字距离效应显著,但大数字距离效应不明显,正常儿童则表现出显著的大小数字距离效应;而无效线索提示条件下,只有正常儿童表现出显著的数字距离效应,ADHD儿童的数字距离效应不显著。
[Abstract]:Using the endogenous and exogenous cues experimental paradigm of Posner, the Arabic numerals (excluding 5) with material 1 / 9 were used to determine whether the target number was greater than 5, the task of which was to determine whether the target number was greater than 5. The effects of endogenous and exogenous attention on the distance effect of ADHD in children with attention deficit hyperactivity disorder (ADHD) were investigated. The results showed that under the condition of endogenous and exogenous attention, the response time of normal children in the task of digital judgment processing was shorter than that of children with ADHD. However, the size and size of ADHD children were not significant under the condition of invalid cues, but normal children still showed significant digital distance effect. (3) the small digital distance effect of ADHD children was significant under the condition of exogenous effective cues. But the large digital distance effect was not obvious, the normal children showed significant size digital distance effect, but under the condition of invalid clue, only the normal children showed significant digital distance effect than the ADHD children's digital distance effect was not significant.
