The present study was conducted to investigate the effects of background noise and working memory capacity on speechreading performance. The results displayed no differences in speechreading performance (i.e. on a word-test and on a sentence-test) due to background noise. When working memory capacity was correlated with speechreading, only one of the two tests of working memory capacity (i.e. the reading span task) was found to be related to speechreading performance. This relationship applies to both speechreading tests, but only to one specific background noise condition in the tests: meaningful noise. The results are discussed with respect to the demands of simultaneous storage and processing in working memory and how these demands apply to speech-based noise distractors. It was also concluded that although performance was similar across different background noise conditions, they apparently engage different components of the individual's cognitive system.
本研究旨在探讨背景噪音和工作记忆容量对言语阅读表现的影响。结果显示，由于背景噪音，言语阅读表现（即单词测试和句子测试）没有差异。当工作记忆容量与言语阅读相关时，发现工作记忆容量的两项测试中只有一项（即阅读广度任务）与言语阅读表现有关。这种关系适用于两项言语阅读测试，但仅适用于测试中的一种特定背景噪音条件：有意义的噪音。针对工作记忆中同时存储和处理的需求以及这些需求如何适用于基于言语的噪音干扰因素进行了讨论。研究还得出结论，尽管在不同背景噪音条件下表现相似，但它们显然涉及个体认知系统的不同组成部分。
