Most research investigating auditory perception is conducted in controlled laboratory settings, potentially restricting its generalizability to the complex acoustic environment outside the lab. The present study, in contrast, investigated auditory attention with long-term recordings (> 6 h) beyond the lab using a fully mobile, smartphone-based ear-centered electroencephalography (EEG) setup with minimal restrictions for participants. Twelve participants completed iterations of two variants of an oddball task where they had to react to target tones and to ignore standard tones. A rapid variant of the task (tones every 2 s, 5 min total time) was performed seated and with full focus in the morning, around noon and in the afternoon under controlled conditions. A sporadic variant (tones every minute, 160 min total time) was performed once in the morning and once in the afternoon while participants followed their normal office day routine. EEG data, behavioral data, and movement data (with a gyroscope) were recorded and analyzed. The expected increased amplitude of the P3 component in response to the target tone was observed for both the rapid and the sporadic oddball. Miss rates were lower and reaction times were faster in the rapid oddball compared to the sporadic one. The movement data indicated that participants spent most of their office day at relative rest. Overall, this study demonstrated that it is feasible to study auditory perception in everyday life with long-term ear-EEG.

移动耳脑电图研究日常生活中的听觉注意力

大多数调查听觉感知的研究都是在受控的实验室环境中进行的,这可能会将其普遍性限制在实验室外的复杂声学环境中。相比之下,本研究使用完全移动的、基于智能手机的耳中心脑电图 (EEG) 设置,对参与者的限制最小,研究了在实验室外进行长期录音(> 6 小时)的听觉注意力。十二名参与者完成了一项古怪任务的两种变体的迭代,他们必须对目标音调做出反应并忽略标准音调。任务的快速变体(每 2 秒一次,总时间 5 分钟)在受控条件下在早上、中午和下午全神贯注地进行。零星的变体(每分钟发出一次音调,总时间 160 分钟)在上午和下午进行一次,而参与者遵循他们正常的办公日例行程序。记录和分析 EEG 数据、行为数据和运动数据(使用陀螺仪)。对于快速和零星的古怪球,观察到响应于目标音调的 P3 分量的预期增加幅度。与零星的相比,快速古怪的球的失误率更低,反应时间更快。运动数据表明,参与者在办公日的大部分时间里都处于相对休息状态。总体而言,这项研究表明,通过长期耳脑电图研究日常生活中的听觉感知是可行的。并记录和分析运动数据(使用陀螺仪)。对于快速和零星的古怪球,观察到响应于目标音调的 P3 分量的预期增加幅度。与零星的相比,快速古怪的球的失误率更低,反应时间更快。运动数据表明,参与者在办公日的大部分时间里都处于相对休息状态。总体而言,这项研究表明,通过长期耳脑电图研究日常生活中的听觉感知是可行的。并记录和分析运动数据(使用陀螺仪)。对于快速和零星的古怪球,观察到响应于目标音调的 P3 分量的预期增加幅度。与零星的相比,快速古怪的球的失误率更低,反应时间更快。运动数据表明,参与者在办公日的大部分时间里都处于相对休息状态。总体而言,这项研究表明,通过长期耳脑电图研究日常生活中的听觉感知是可行的。运动数据表明,参与者在办公日的大部分时间里都处于相对休息状态。总体而言,这项研究表明,通过长期耳脑电图研究日常生活中的听觉感知是可行的。运动数据表明,参与者在办公日的大部分时间里都处于相对休息状态。总体而言,这项研究表明,通过长期耳脑电图研究日常生活中的听觉感知是可行的。
