The aim of this study was to examine the involvement of the short-term memory system in complex mental addition by manipulating the phonological and visual similarity of two numbers to be added. The phonological similarity of the problems appeared to have a major effect on both speed and accuracy. However, the manipulation of visual similarity failed to have any measurable impact. This suggests that the phonological loop, rather than the visual-spatial sketch pad, would be used preferably for temporary storage of addends. An interpretation of these results in terms of the nature of the internal code underlying this task is discussed.
本研究的目的是通过操纵两个要相加数字的语音和视觉相似性，来检验短期记忆系统在复杂心算中的参与情况。问题的语音相似性似乎对速度和准确性都有重大影响。然而，视觉相似性的操纵未能产生任何可测量的影响。这表明，语音回路而非视觉空间画板，更适合用于临时存储加数。本文讨论了根据该任务潜在内部代码的性质对这些结果的解释。
