随着认知听觉科学的出现，人们越来越多地关注认知功能的个体差异及其在解释噪声中言语加工中听者间差异的解释力。工作记忆是近年来备受关注的心理结构。经验证据确实证实了在老年听力受损的听众中WM容量（WMC）和SiN识别之间的关联。然而，一些理论模型提出，WMC的变化是所有听众在不利感知条件下语音处理能力变化的重要预测因素，并且这个概念在该领域内已被广泛接受。为了评估WMC是否也发挥作用时，没有听力损失的听众在不利的听力条件下处理语音，我们调查了已发表和未发表的研究，其中阅读广度测试（广泛使用的WMC测量）与SiN识别的措施一起管理，使用听力学和听力研究中常用的句子材料。一项荟萃分析显示，对于听力正常的年轻听众，WMC的个体差异估计平均占SiN识别分数的方差不到2%。这一结果警告反对（直观上吸引人的）假设，WMC的个体变化是独立的年龄和听力状态的听众的SiN识别的预测。
With the advent of cognitive hearing science, increased attention has been given to individual differences in cognitive functioning and their explanatory power in accounting for inter-listener variability in the processing of speech in noise (SiN). The psychological construct that has received much interest in recent years is working memory. Empirical evidence indeed confirms the association between WM capacity (WMC) and SiN identification in older hearing-impaired listeners. However, some theoretical models propose that variations in WMC are an important predictor for variations in speech processing abilities in adverse perceptual conditions for all listeners, and this notion has become widely accepted within the field. To assess whether WMC also plays a role when listeners without hearing loss process speech in adverse listening conditions, we surveyed published and unpublished studies in which the Reading-Span test (a widely used measure of WMC) was administered in conjunction with a measure of SiN identification, using sentence material routinely used in audiological and hearing research. A meta-analysis revealed that, for young listeners with audiometrically normal hearing, individual variations in WMC are estimated to account for, on average, less than 2% of the variance in SiN identification scores. This result cautions against the (intuitively appealing) assumption that individual variations in WMC are predictive of SiN identification independently of the age and hearing status of the listener.
