近似数字系统(ANS)是一种固有的认知模板,可以在心理上表征近似的大小,并且与符号数字知识和数学能力的联系存在争议。最近的一系列研究发现,利用 ANS 的近似算术训练(AAT)任务可以提高数学技能,这不仅支持了这种联系的存在,而且表明它可能是因果关系。然而,尚未报道对任何 ANS 测量的直接转移效应,这引发了对数学改进可能出现的机制的质疑。本研究调查了 7 天 AAT 的影响,并成功地将先前报告的转移效应复制到数学中。此外,我们的探索性分析提供了初步证据,表明某些 ANS 相关技能也可能容易受到培训。我们得出的结论是,AAT 对数学成绩具有可重复的影响,并为未来的研究提供了进一步探索潜在机制的途径,特别是数学改进和 ANS 技能改进之间的联系。
The approximate number system (ANS) is an innate cognitive template that allows for the mental representation of approximate magnitude, and has been controversially linked to symbolic number knowledge and math ability. A series of recent studies found that an approximate arithmetic training (AAT) task that draws upon the ANS can improve math skills, which not only supports the existence of this link, but suggests it may be causal. However, no direct transfer effects to any measure of the ANS have yet been reported, calling into question the mechanisms by which math improvements may emerge. The present study investigated the effects of a 7-day AAT and successfully replicated previously reported transfer effects to math. Furthermore, our exploratory analyses provide preliminary evidence that certain ANS-related skills may also be susceptible to training. We conclude that AAT has reproducible effects on math performance, and provide avenues for future studies to further explore underlying mechanisms - specifically, the link between improvements in math and improvements in ANS skills.
