We quantified EEG signals associated with the selective attention processing of experienced simultaneous interpreters using phase-lock responses induced from a 40-Hz-ASSR, which is robust to environmental changes. We divided our participants into two groups based on simultaneous interpretation experience: S-rank (n = 7) with over 15 years and C-rank (n = 15) with less than 1 year. We extracted the phase-locked responses induced by the 40-Hz-ASSR signals and calculated the value of the inter-trial coherence (ITC) and compared the simultaneous interpretation (SI) and shadowing (SH) conditions. On the anterior electrodes, the ITC value of the S-rank on the SI condition was significantly higher than the value of the SH condition, and no significant difference was detected on the C-rank between the conditions. Since the difference between SI and SH reflects the attention processing related to multiple language control of SI, we argue that the 40-Hz-ASSR method adequately verifies the continuous change of the selective attention processing of SI under real environments.

使用EEG锁相响应的经验丰富的同声传译者的选择性注意测量

我们使用从40 Hz-ASSR感应到的锁相响应来量化与经验丰富的同声传译员的选择性注意处理相关的EEG信号，该信号对环境变化具有鲁棒性。根据同声传译经验，我们将参与者分为两组：S级（n = 7）超过15年，C级（n = 15）不到1年。我们提取了由40 Hz-ASSR信号引起的锁相响应，并计算了试验间相干性（ITC）的值，并比较了同声传译（SI）和阴影（SH）条件。在前电极上，SI条件下S等级的ITC值显着高于SH条件下的ITC值，并且在两个条件之间在C等级上未检测到显着差异。
