为了探讨口译经验如何影响青年人的执行功能，本研究采用Flanker任务，对具有不同口译经验的大学生进行了两项ERP研究。实验一发现，口译经验越丰富的被试在一致和不一致条件下的N1和N2波幅越大，这分别说明口译在早期注意加工和注意监控方面具有优势。对于反应时数据，口译经验越多的组干扰效应越小，表现出抑制的优势。P3的结果是相当混合的，前半P3时间窗的结果主要支持监测优势，后半的结果主要支持抑制优势。实验2重复实验1与两个参与者组更密切匹配的年龄和L2 AoA。结果的模式与实验1中的模式相似，不同之处在于来自P3组分的抑制优势出现得更早，并且RT数据中的抑制优势仅略微显著。这两个实验的结果都可以沿着加工的时间进程整合成一个连贯的整体，表明口译经验可以增强早期注意加工、冲突监控和干扰抑制，后两者是抑制控制的一部分。
To explore how interpreting experience may modulate young adults' executive functioning, the present study conducted two ERP studies using the Flanker task, and recruited university students of more or less interpreting experience. Experiment 1 revealed that participants of more interpreting experience exhibited larger N1 and N2 amplitudes in both congruent and incongruent conditions, which, according to previous research, are respectively evidence for advantages in early attentional processing and monitoring. As for the response time (RT) data, a smaller interference effect for the group of more interpreting experience was obtained, showing an advantage in inhibition. The P3 results were quite mixed, with the results of the first half P3 time window mainly supporting a monitoring advantage, and the results of the second half mainly supporting an inhibition advantage. Experiment 2 replicated Experiment 1 with two participant groups more closely matched in age and L2 AoA. The pattern of the results was similar to that in Experiment 1, except that the inhibition advantage from the P3 component appeared earlier, and that the inhibition advantage in RT data was only marginally significant. Both experiments have produced results that can be integrated into a coherent whole along the time course of processing, indicating that interpreting experience may enhance early attentional processing, conflict monitoring and interference suppression, with the latter two as parts of inhibitory control.
