Nowadays a popular technique to improve mood and cognition is auditory beat stimulation (ABS), which is thought to induce a frequency-following response of brainwaves. The main types of ABS are monaural beats (MB) and binaural beats (BB). BB involves the presentation of a specific frequency to one ear and another frequency to the other ear which may induce neural entrainment. A difference between the frequencies of 40 Hz is assumed to improve cognition. The present study examined the effect of 40 Hz binaural beats (BB) and monaural beats (MB) on attention and electroencephalography (EEG). A total of 25 first-year psychology students (11 males, 14 females) performed a Flanker task while EEG was recorded during the 5 min-presentation of pink noise (PN), MB and BB. With respect to attention, as measured by the Flanker task, the number of false responses in the BB condition was smaller than that in the PN condition while the number of false responses in the MB condition was larger as compared to the PN condition. As there was no association of BB with a consistent increase in absolute 40 or 45 Hz power compared to PN or MB, EEG recordings could not confirm the hypothesized neural entrainment in the brain. Overall, the current findings show that listening to 40 Hz BB improves attention but do not show the occurrence of neural entrainment. Future research is recommended to include a larger sample, to use a broader cognitive test battery and to present auditory beats with a longer duration.

双耳和单耳节拍刺激对注意力和脑电图的影响

现在一种流行的改善情绪和认知的技术是听觉节拍刺激(ABS),它被认为可以诱导脑电波的频率跟随反应。ABS的主要类型是单耳节拍(MB)和双耳节拍(BB)。BB 涉及向一只耳朵呈现特定频率,向另一只耳朵呈现另一个频率,这可能会导致神经夹带。假设 40 Hz 频率之间的差异可以提高认知能力。本研究检查了 40 Hz 双耳节拍 (BB) 和单耳节拍 (MB) 对注意力和脑电图 (EEG) 的影响。共有 25 名一年级心理学学生(11 名男性,14 名女性)执行了 Flanker 任务,同时在 5 分钟呈现粉红噪声 (PN)、MB 和 BB 期间记录脑电图。关于注意力,由 Flanker 任务衡量,BB 条件下的错误响应数小于 PN 条件下的错误响应数,而 MB 条件下的错误响应数大于 PN 条件下的错误响应数。由于与 PN 或 MB 相比,BB 与绝对 40 或 45 Hz 功率的持续增加没有关联,EEG 记录无法证实大脑中假设的神经夹带。总的来说,目前的研究结果表明,听 40 Hz BB 可以提高注意力,但没有显示神经夹带的发生。建议未来的研究包括更大的样本,使用更广泛的认知测试电池并呈现持续时间更长的听觉节拍。由于与 PN 或 MB 相比,BB 与绝对 40 或 45 Hz 功率的持续增加没有关联,EEG 记录无法证实大脑中假设的神经夹带。总的来说,目前的研究结果表明,听 40 Hz BB 可以提高注意力,但没有显示神经夹带的发生。建议未来的研究包括更大的样本,使用更广泛的认知测试电池并呈现持续时间更长的听觉节拍。由于与 PN 或 MB 相比,BB 与绝对 40 或 45 Hz 功率的持续增加没有关联,EEG 记录无法证实大脑中假设的神经夹带。总的来说,目前的研究结果表明,听 40 Hz BB 可以提高注意力,但没有显示神经夹带的发生。建议未来的研究包括更大的样本,使用更广泛的认知测试电池并呈现持续时间更长的听觉节拍。
