本研究采用注意瞬脱实验范式探讨了语义信息在数量表征中的作用。结果发现：（1）在双任务方式中,字母辨认任务对大数（5及以上）的辨认产生干扰,但不影响小数（4及以下）的辨认绩效;（2）数量表征在视野上出现差异性,表现为在小数辨认时,左侧视野呈现绩效高于右侧;大数辨认正好相反,即右侧视野呈现高于左侧。结果表明,语义信息在表征小数和大数中的作用不同：小数的表征无需语言参与;而大数则更多地涉及语义信息,可能需语音回路中无声复述机制的参与。

The role of semantic information on large and small number representations was investigated by the attentional blink （AB） experimental paradigm. The results showed：（1） In the dual task, the letter discrimination task impaired the subsequent large number recognition performance,but did not to the small number task; （2） There was an asymmetry of number recognition perfor- mance in different visual-field, i. e., the better perfor- mance for the small number task was in the left-visual-field but for the large number task was in right-visual- field. The results suggested that the small number con- cept may be independent of language, but the large number concept may be based on semantic representa- tion that number words and Arabic symbols are sub-vo- cally rehearsed in phonological loop.
