在最近的一项研究中，Gevers和他的同事（2010,Journal of Experimental Psychology: General, Vol. 139, pp. 180-190）表明，在成人中，SNARC（反应编码的空间数字关联）效应不仅来自于量级的空间编码（例如，心理数轴假设），也来自于言语编码。因为孩子们在教室里被尺子、数轴等东西包围着，所以直觉上很有吸引力地认为，他们首先使用他们的心理数轴来表示数字，只有在后来的发展中，才会发生对大小信息的口头重新编码。然而，这个假设从未被验证过。本研究的目的是在解释SNARC效应时定义空间和语言两种描述的发展模式。为此，9岁和11岁的孩子接受了一项大小比较任务的测试。令人惊讶的是，在两个年龄组中都观察到了量级信息的语言编码清晰而有力的证据。我们的研究结果表明，在正规学校教育的早期，使用语言编码信息的能力就已经很强了。(C) 2011爱思唯尔公司版权所有。
In a recent study, Gevers and colleagues (2010, Journal of Experimental Psychology: General, Vol. 139, pp. 180-190) showed that the SNARC (spatial numerical association of response codes) effect in adults results not only from spatial coding of magnitude (e.g., mental number line hypothesis) but also from verbal coding. Because children are surrounded by rulers, number lines, and the like in the classroom, it is intuitively appealing to assume that they first use their mental number line to represent numbers and that only later in development a verbal recoding of magnitude information takes place. However, this hypothesis has never been tested. The goal of the current study was to define the developmental pattern of both accounts (spatial and verbal) in explaining the SNARC effect. To this end, 9- and 11-year-olds were tested in a magnitude comparison task. Surprisingly, clear and robust evidence for verbal coding of magnitude information was observed in both age groups. Our results imply that the ability to use verbal coding of magnitude information is robustly present early in formal schooling. (C) 2011 Elsevier Inc. All rights reserved.
