Abstract: In the present study, Posner's endogenous and exogenous experimental paradigms were used to investigate ADHD and normal children's number distance effect of number processing. The stimuli were 1~9 Arabic numbers(not including 5). Subjects' task was to decide whether the presented number was larger or smaller than 5. The results showed that: 1)In the endogenous and exogenous attentions, ADHD children performed slowly than normal children on the behavioral performance. 2)In valid condition of endogenous attention, both ADHD and normal children showed significant number distance effect, but in invalid condition of endogenous attention, just normal children performed significant number distance effect, not ADHD children. 3)in valid condition of exogenous attention, ADHD children showed significant small number distance effect, and large number distance was disappeared; normal children showed significant both small and large number distance effect. But in invalid condition, only did normal children perform significant number distance effect, not ADHD children.

Key words: endogenous attention, exogenous attention, number processing, number distance effect, ADHD

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。
