摘要
采用内源性注意和外源性注意实验范式,材料为小数(1～4)和大数(6～9)的阿拉伯数字,以判断数字是否大于5为任务,考察内源性和外源性线索不同注意条件下SOA对数字距离效应的影响。结果发现:(1)内源性线索条件下,随着SOAs增加,大小数的距离效应逐渐增大,当SOA为900ms时,大小数的距离效应最明显;(2)外源性线索条件下,当SOA为300ms时,大小数的距离效应最显著,随着SOAs增加,大小数的距离效应逐渐减小。
In the present study, endogenous and exogenous experimental paradigms were used to investigate the number distance effect in attended or unattended conditions when SOAs were different. The stimuli weresmall numbers （1-4） and large Arabic numbers （6 -9）. The subjects＇ task was to decide whether the presented number was larger or smaller than 5. The results showed that （ 1 ） in the endogenous cue, with SOAs increasing, the distance effects of large and small numbers gradually increased. When SOA was 900ms, the distance effect of large or small numbers was most significant; （2） in the exogenous cue, when SOA was 300ms, the distance effect of large or small numbers was most significant. With the increasing of SOAs, however, the distance effect of large and small numbers gradually decreased.
