Research suggests that listening to white noise may improve some aspects of cognitive performance in individuals with lower attention. This study investigated the impact of white noise on new word learning in healthy young adults, and whether this effect was mediated by executive attention skills. Eighty participants completed a single training session to learn the names of twenty novel objects. The session comprised 5 learning phases, each followed by a recall test. A final recognition test was also administered. Half the participants listened to white noise during the learning phases, and half completed the learning in silence. The noise group demonstrated superior recall accuracy over time, which was not impacted by participant attentional capacity. Recognition accuracy was near ceiling for both groups. These findings suggest that white noise has the capacity to enhance lexical acquisition.
研究表明，在注意力较低的个体中，听白噪声可能会改善认知表现的某些方面。本研究调查了白噪声对健康年轻成年人新单词学习的影响，以及这种影响是否受到执行注意技能的调节。80 名参与者完成了一次学习课程，以学习 20 个新物体的名称。课程包括 5 个学习阶段，每个阶段后进行一次回忆测试。还进行了最后一次识别测试。一半的参与者在学习阶段听白噪声，另一半则在安静的环境中完成学习。随着时间的推移，噪声组的回忆准确性更高，而参与者的注意力能力对其没有影响。两个组的识别准确性都接近上限。这些发现表明，白噪声有能力增强词汇习得。
