Recent evidence has highlighted the important role that number-ordering skills play in arithmetic abilities, both in children and adults. In the current study, we demonstrated that number comparison and ordering skills were both significantly related to arithmetic performance in adults, and the effect size was greater in the case of ordering skills. Additionally, we found that the effect of number comparison skills on arithmetic performance was mediated by number-ordering skills. Moreover, performance on comparison and ordering tasks involving the months of the year was also strongly correlated with arithmetic skills, and participants displayed similar (canonical or reverse) distance effects on the comparison and ordering tasks involving months as when the tasks included numbers. This suggests that the processes responsible for the link between comparison and ordering skills and arithmetic performance are not specific to the domain of numbers. Finally, a factor analysis indicated that performance on comparison and ordering tasks loaded on a factor that included performance on a number line task and self-reported spatial thinking styles. These results substantially extend previous research on the role of order processing abilities in mental arithmetic.
最近的证据突出了数字排序技能在儿童和成人算术能力中所起的重要作用。在本研究中，我们证明数字比较和排序技能均与成人的算术表现显著相关，且在排序技能方面效应量更大。此外，我们发现数字比较技能对算术表现的影响是由数字排序技能介导的。此外，涉及一年中月份的比较和排序任务的表现也与算术技能密切相关，并且参与者在涉及月份的比较和排序任务中表现出与包含数字的任务类似的（规范或反向）距离效应。这表明负责比较和排序技能与算术表现之间联系的过程并非数字领域所特有。最后，一项因素分析表明，比较和排序任务的表现加载在一个因素上，该因素包括数轴任务的表现和自我报告的空间思维方式。这些结果极大地扩展了先前关于顺序处理能力在心算中作用的研究。
