空间-数字联合反应编码效应的空间参照框架解释

Spatial reference frames account for the SNARC effect

数字认知的研究表明,数字可系统表征到相应的空间位置,即较小数字与左侧空间相关联,较大数字与右侧空间相关联。关于数字与空间联结的主要证据是空间-数字联合反应编码效应(SNARC效应)。当前大量研究证实SNARC效应是普遍存在的,但关于效应的产生机制仍存在着争论。本文在梳理分析相关研究基础上,总结了空间参照框架对SNARC效应的影响,分析了某一特定空间参照框架、空间参照框架组织(多重参照框架、激活次级参照框架)在SNARC效应产生中的重要作用。但空间参照框架是否是SNARC效应产生的必要条件,仍需要进一步的探究。

Investigations of numerical cognition have shown that numbers are systematically mapped onto spatial locations: Smaller numbers are associated with the left side of space and larger numbers with the right side of space. The earliest demonstration of this mapping is the spatial - numerical association of response codes (SNARC) effect (Dehaene,Bossini,& Giraux,1993). However, its mechanism is still the subject of debate. According to the summarization and analysis of the related literatures, we found that the possible role of specific spatial reference frames, multiple reference frames, activating secondary reference frames played important roles in the SNARC effect. As should be evident from this review, a substantial body of evidence now actually existed to highlight the importance that spatial reference frames, have with respect to determining the SNARC effect. Nonetheless, none of this work has served to demonstrate that the presence of such frames represents a necessary condition for the manifestation of this effect,which needs further research.
