摘要：  大量研究证实数字空间联结是一种稳定存在的表征形式。而关于数字空间联结的机制目前仍存在较大争论, 本文在系统整理了大量有关长时记忆“心理数字线”难以解释的研究后, 分析总结了工作记忆在数字空间联结中的重要作用。基于多个研究任务分析了工作记忆不同成分, 即中央执行、语音环路和视空模板等, 在数字空间联结中的重要作用, 并系统介绍了对数字空间联结的工作记忆序列位置的解释。总之, 数字空间联结的工作记忆机制仍有较多需要解决的问题, 具有进一步探索的广泛空间。

Abstract:  The SNARC (Spatial-Numerical Association of Response Codes) effect, first reported by Dehaene, Bossini, and Giraux in 1993, means that individuals, when completing basic number processing tasks, typically react faster with their left hands to relatively smaller numbers and faster with their right hands to relatively larger numbers. The SNARC effect has been shown to be stable and robust, but its mechanism is still the subject of debate over the past 20 years. As a Mental Number Line (preexists in long-term memory) account cannot capture the complexity of observations reported in the literature, we aimed to explore the working memory account for the SNARC effect. According to the summarization and analysis of the related literatures, we found that the central executive, phonological subsystems, and the visual subsystems all played important roles in the SNARC effect, and the ordinal position in the sequence in working memory was also a an influential factor of the SNARC effect. However, additional neuroimaging studies are needed to examine the mechanism underlying the SNARC effect.

Key words:  SNARC effect, inhibitory control, phonological subsystems, visual subsystems, ordinal position effect
