Evidence for sequential associative word learning in the auditory domain has been identified in infants, while adults have shown difficulties. To better understand which factors may facilitate adult auditory associative word learning, we assessed the role of auditory expertise as a learner-related property and stimulus order as a stimulus-related manipulation in the association of auditory objects and novel labels. We tested in the first experiment auditorily-trained musicians versus athletes (high-level control group) and in the second experiment stimulus ordering, contrasting object-label versus label-object presentation. Learning was evaluated from Event-Related Potentials (ERPs) during training and subsequent testing phases using a cluster-based permutation approach, as well as accuracy-judgement responses during test. Results revealed for musicians a late positive component in the ERP during testing, but neither an N400 (400-800 ms) nor behavioral effects were found at test, while athletes did not show any effect of learning. Moreover, the object-label-ordering group only exhibited emerging association effects during training, while the label-object-ordering group showed a trend-level late ERP effect (800-1200 ms) during test as well as above chance accuracy-judgement scores. Thus, our results suggest the learner-related property of auditory expertise and stimulus-related manipulation of stimulus ordering modulate auditory associative word learning in adults.
在听觉领域，已经发现婴儿具有顺序联想词汇学习的证据，而成年人则表现出困难。为了更好地理解哪些因素可能促进成年人的听觉联想词汇学习，我们评估了听觉专长作为学习者相关属性的作用，以及刺激顺序作为刺激相关操作在听觉物体和新标签关联中的作用。我们在第一个实验中测试了受过听觉训练的音乐家与运动员（高水平对照组），并在第二个实验中测试了刺激顺序，对比了物体-标签与标签-物体呈现。使用基于聚类的置换方法，从训练和随后的测试阶段的事件相关电位（ERP）评估学习，以及在测试期间使用准确性判断反应进行评估。结果表明，音乐家在测试期间的 ERP 中出现了一个晚期正成分，但在测试中既没有发现 N400（400-800 毫秒），也没有发现行为效应，而运动员则没有表现出任何学习效应。此外，只有物体-标签顺序组在训练期间表现出了明显的关联效应，而标签-物体顺序组在测试期间表现出了晚期 ERP 效应的趋势水平（800-1200 毫秒），以及高于机会的准确性判断分数。因此，我们的结果表明，听觉专长作为学习者相关属性和刺激顺序作为刺激相关操作，调节了成年人的听觉联想词汇学习。
