In elementary symbolic number processing, the comparison distance effect (in a comparison task, the task is more difficult with smaller numerical distance between the values) and the priming distance effect (in a number processing task, actual number is easier to process with a numerically close previous number) are two essential phenomena. While a dominant model, the approximate number system model, assumes that the two effects rely on the same mechanism, some other models, such as the discrete semantic system model, assume that the two effects are rooted in different generators. In a correlational study, here we investigate the relation of the two effects. Critically, the reliability of the effects is considered; therefore, a possible null result cannot be attributed to the attenuation of low reliability. The results showed no strong correlation between the two effects, even though appropriate reliabilities were provided. These results confirm the models of elementary number processing that assume distinct mechanisms behind number comparison and number priming.
在基本符号数字处理中，比较距离效应（在比较任务中，数值之间的距离越小，任务越困难）和启动距离效应（在数字处理任务中，实际数字与接近的前一个数字的数值距离越近，处理起来越容易）是两个基本现象。虽然主导模型——近似数量系统模型——假设这两个效应依赖于相同的机制，但其他一些模型，如离散语义系统模型，则假设这两个效应根植于不同的发生器中。在一项相关研究中，我们在这里研究了这两个效应之间的关系。关键是，考虑到了效应的可靠性；因此，不可能将可能的零结果归因于低可靠性的衰减。结果表明，即使提供了适当的可靠性，这两个效应之间也没有很强的相关性。这些结果证实了基本数字处理模型，这些模型假设数字比较和数字启动背后存在不同的机制。
