We utilized the event-related potential (ERP) technique to study neural activity associated with different levels of working memory (WM) load during simultaneous interpretation (SI) of continuous prose. The amplitude of N1 and P1 components elicited by task-irrelevant tone probes was significantly modulated as a function of WM load but not the direction of interpretation. Furthermore, the latency of the P1 increased significantly with WM load. The WM load effect on N1 latency, however, did not reach significance. Larger negativity under lower WM loads suggests that more attention is available to process the source message, providing the first electrophysiological evidence in support of the Efforts Model of SI. Relationships between the direction of interpretation and median WM load are also discussed.
我们利用事件相关电位 (ERP) 技术研究了连续散文同声传译 (SI) 过程中不同工作记忆 (WM) 负荷水平相关的神经活动。任务无关的音调探测刺激诱发的 N1 和 P1 成分的振幅随着 WM 负荷的变化而显著调节，但与口译方向无关。此外，P1 的潜伏期随着 WM 负荷的增加而显著增加。然而，WM 负荷对 N1 潜伏期的影响并未达到显著水平。在较低 WM 负荷下的更大负性表明，有更多的注意力可用于处理源消息，为 SI 的努力模型提供了第一个电生理证据支持。还讨论了口译方向与 WM 负荷中位数之间的关系。
