Abstract: It is usually thought that numbers are represented on a mental number line on which the progression of smaller to larger numbers occurs from left to right suggesting a spatial representation of numbers. The present research using Dehaene′s paradigm, ″thousand″ as the baseline, a rectangle-frame was firstly displayed in the center of the screen as fixation, then a counting unit was displayed in the center of fixation. The participant should classify the counting unit as quickly and accurately as possible. The results showed that:(1)There are the same mechanism to the Counting unit and digital processing, participants responded faster to the left-side decision for the small counting unit and faster to the right-side decisions for big counting unit. The data showed that SNARC effect appeared in the present experiment.(2)SNARC effect could arise not only in the numerical magnitude information processing of spatial representation; it also could appear in the order of representation on the space. These results suggested that the counting units are mapped onto the mental number line.

Key words: counting unit, mental number line, SNARC effect

摘要: 采用Dehaene等人的研究范式,以计数单位中的“千”为基线,要求被试快速作大于“千”还是小于“千”的分类判断,考察计数单位在心理数字线上的空间表征方式。结果表明:(1)计数单位和数字有着相同的加工机制,小计数单位表征在心理数字线的左侧,大计数单位表征在心理数字线的右侧,存在显著的SNARC效应。(2)SNARC效应不仅仅出现在数量的空间表征上,同样能够出现在顺序信息的空间表征上。
