以往的研究表明，词汇/语义因素对即时序列识别的影响与对即时序列回忆的影响不同。这被认为是语言知识在回忆的再整合过程中有助于言语短期记忆的证据。与此观点相反，我们发现词汇量、频率和可想象性都会影响匹配广度。标准的匹配跨度任务，需要改变被检测的项目顺序，比一个涉及检测音素顺序从而改变项目身份的新任务更不容易受到词汇/语义因素的影响。因此，在即时识别和即时序列回忆中，词汇/语义知识对项目识别的贡献大于对项目顺序记忆的贡献。任务敏感性，而不是缺乏显性回忆，可能是之前未能显示这些变量在即时识别中的影响的基础。我们还比较了纯和不可预测的单词和非单词混合列表的匹配广度。词汇性对纯粹列表的即时识别比混合列表的影响更大，这与即时序列回忆的研究结果一致。列表组成对音素的检测有影响，但对匹配广度中项目顺序的变化没有影响；同样，回想一下，混合列表产生更频繁的单词音素迁移，而不是整个项目的迁移。这些结果表明，即时序列回忆和识别之间有很强的相似性。词汇/语义知识可能有助于这两个任务的语音稳定性。
Previous studies have reported that, in contrast to the effect on immediate serial recall, lexical/semantic factors have little effect on immediate serial recognition. This has been taken as evidence that linguistic knowledge contributes to verbal short-term memory in a redintegrative process at recall. Contrary to this view, we found that lexicality, frequency, and imageability all influenced matching span. The standard matching span task, requiring changes in item order to be detected, was less susceptible to lexical/semantic factors than was a novel task involving the detection of phoneme order and hence item identity changes. Therefore, in both immediate recognition and immediate serial recall, lexical/semantic knowledge makes a greater contribution to item identity than to item order memory. Task sensitivity, and not the absence of overt recall, may have underpinned previous failures to show effects of these variables in immediate recognition. We also compared matching span for pure and unpredictable mixed lists of words and nonwords. Lexicality had a larger impact on immediate recognition for pure than for mixed lists, in line with findings for immediate serial recall. List composition affected the detection of phoneme but not item order changes in matching span; similarly, in recall, mixed lists produce more frequent word phoneme migrations but not migrations of entire items. These results point to strong similarities between immediate serial recall and recognition. Lexical/semantic knowledge may contribute to phonological stability in both tasks.
