Abstract

The SPoARC (spatial-positional association of response codes) effect refers to a mental spatialization of ordinal information in working memory. In the present study, we investigated how spatialization can be modulated by the number of items to be maintained in working memory. In Experiment 1, 139 participants performed a spatialization task with sequences of either two, three, four, or five items using a between-subjects design. The results showed a significant spatialization effect for all sequence lengths except for sequences of five items. In Experiment 2, 96 participants performed the same spatialization task for sequences of three, four, and five items, but using a within-subject design. The results confirmed the absence of a SPoARC effect for sequences of five items, and showed a greater effect for sequences of four items. Overall, our findings suggest that working memory load is a moderator of the spatialization effect. In addition, we found that spatialization was in part modulated by participants' spatial abilities.

反应代码的空间位置关联受工作记忆中项目数量的调节。

SpoARC（反应代码的空间位置关联）效应指的是工作记忆中顺序信息的心理空间化。在本研究中，我们探讨了工作记忆中的项目数量如何调节空间化。在实验 1 中，139 名被试采用被试间设计完成了一项空间化任务，该任务包含两个、三个、四个或五个项目的序列。结果显示，除五个项目的序列外，所有长度的序列都有明显的空间化效应。在实验 2 中，96 名被试针对三个、四个和五个项目的序列进行了同样的空间化任务，但采用的是被试内设计。结果证实，五个项目的序列不存在 SPoARC 效应，而四个项目的序列则显示出更大的效应。总之，我们的研究结果表明，工作记忆负荷是空间化效应的调节因素。此外，我们还发现空间化在一定程度上受到参与者空间能力的调节。
