摘要
采用内源性注意和外源性注意实验范式,以判断数字奇偶为任务,材料为1～9的阿拉伯数字,考察内源性和外源性线索不同注意条件下中小学生的数字加工SNARC效应。结果发现:(1)内源性线索和外源性线索条件下,中小学生在数字加工任务中所表现出来的SNARC效应随着年龄增长逐渐增大;(2)内源性线索和外源性线索注意条件下,各年级学生均表现出显著的SNARC效应;(3)内源性线索非注意条件下,中学生能够表现出显著的SNARC效应,但小学生的SNARC效应不明显;外源性线索非注意条件下,高中生能够表现出显著的SNARC效应,但小学生和初中生的SNARC效应不明显,说明外源性注意对中小学生数字加工SNARC效应的影响比内源性注意大,且对SNARC效应的影响主要表现在较大的数字8和9上。
In present study, endogenous and exogenous experimental paradigms were used to investigate primary and middle school students＇ SNARC effect of number processing in attended or unattended conditions. The stimuli were numbers （1 - 9） in Arabic. Subjects＇ task was to decide whether the presented number was odd or even. The results showed that ： （ 1 ） in the endogenous and exogenous cues, the development of the SNARC effect increased with age from primary school to senior high school under the task of number processing. （2） in attended conditions of endogenous and exogenous cues, there were significant SNARC effects from primary school to senior high school students. （3） in unattended condition of endogenous cue, there were significant SNARC effects in middle school students, but not in primary school students; in unattended condition of exogenous cue, there was significant SNARC effect in senior high school students, but not in primary and junior high school students. Moreover, the influence of unattended condition on SNARC effect was mainly found in the large numbers （8, 9）.
