Listening to white noise may facilitate cognitive performance, including new word learning, for some individuals. This study investigated whether auditory white noise facilitates the learning of novel written words from context in healthy young adults. Sixty-nine participants were required to determine the meaning of novel words placed within sentence contexts during a silent reading task. Learning was performed either with or without white noise, and recognition of novel word meanings was tested immediately after learning and after a short delay. Immediate recognition accuracy for learned novel word meanings was higher in the noise group relative to the no noise group, however this effect was no longer evident at the delayed recognition test. These findings suggest that white noise has the capacity to facilitate meaning acquisition from context, however further research is needed to clarify its capacity to improve longer-term retention of meaning.
听白噪声可能会促进某些人的认知表现，包括学习新单词。本研究调查了听觉白噪声是否有助于健康的年轻成年人从语境中学习新的书面单词。69 名参与者需要在默读任务中确定置于句子语境中的新单词的含义。在学习过程中，要么使用白噪声，要么不使用白噪声，并且在学习后立即和短暂延迟后测试对新单词含义的识别。在噪声组中，学习的新单词含义的即时识别准确率高于无噪声组，但是在延迟识别测试中，这种效果不再明显。这些发现表明，白噪声有能力促进从语境中获取意义，但是需要进一步的研究来阐明其改善意义的长期保留能力。
