有序组织信息的加工是串行顺序工作记忆和数字认知的一个特征。在工作记忆中，列表中项目的序列位置遵循有序组织，而数字则基于存储在长期记忆中的有序结构。我们检验了长时数字顺序表征支持工作记忆中临时序列位置信息编码的假设。在实验1中，学到的单词-数字协会似乎有一个负面的，而不是一个积极的影响，立即串行回忆性能相对于控制条件。实验2表明，这种效果是由于一个更强的机会，学习协会的话，在控制列表中的串行位置相比，实验列表。实验3表明，当控制这些位置的学习效果，有没有可靠的影响，学习的单词数量协会立即系列回忆性能。本研究表明，数字代码并没有发挥主要作用，在编码序列的位置信息的工作任务。与此同时，强大的项目位置学习效果表明，长期项目位置协会的贡献，立即记忆的顺序。
The processing of ordinally organized information is a characteristic of both serial-order working memory and numerical cognition. Serial positions of items presented within a list follow an ordinal organization when stored in working memory, whereas numbers are based on an ordinal structure stored in long-term memory. We tested the hypothesis that long-term numerical ordinal representations support the coding of temporary serial position information in working memory. In Experiment 1, learned word-number associations appeared to have a negative instead of a positive impact on immediate serial recall performance relative to control conditions. Experiments 2 showed that this effect was due to a stronger opportunity for learning associations of words to serial positions in the control lists as compared to the experimental lists. Experiment 3 showed that when controlling for these positional learning effects, there was no reliable effect of learned word-number associations on immediate serial recall performance. This study indicates that numerical codes do not play a major role in coding serial position information in working tasks. At the same time, the robust item-position learning effects demonstrate a contribution of long-term item-position associations to immediate memory for order.
