Abstract:
According to the arousal-mood hypothesis, changes in arousal and mood when exposed to auditory stimulation underlie the detrimental effects or improvements in cognitive performance. Findings supporting or against this hypothesis are, however, often based on subjective ratings of arousal rather than autonomic/physiological indices of arousal. To assess the arousal-mood hypothesis, we carried out a systematic review of the literature on 31 studies investigating cardiac, electrodermal, and pupillometry measures when exposed to different types of auditory stimulation (music, ambient noise, white noise, and binaural beats) in relation to cognitive performance. Our review suggests that the effects of music, noise, or binaural beats on cardiac, electrodermal, and pupillometry measures in relation to cognitive performance are either mixed or insufficient to draw conclusions. Importantly, the evidence for or against the arousal-mood hypothesis is at best indirect because autonomic arousal and cognitive performance are often considered separately. Future research is needed to directly evaluate the effects of auditory stimulation on autonomic arousal and cognitive performance holistically.
摘要:
根据唤醒情绪假说,当暴露于听觉刺激时,唤醒和情绪的变化是认知表现的有害影响或改善的基础。支持或反对这一假设的发现是,然而,通常基于唤醒的主观评分,而不是唤醒的自主神经/生理指标。为了评估唤醒情绪假说,我们对31项研究心脏,皮肤电,当暴露于不同类型的听觉刺激(音乐,环境噪声,白噪声,和双耳节拍)与认知表现有关。我们的审查表明,音乐的影响,噪音,或者双耳心跳,皮肤电,与认知表现有关的瞳孔测量要么是混合的,要么不足以得出结论。重要的是,支持或反对唤醒情绪假说的证据充其量是间接的,因为自主神经唤醒和认知表现通常是分开考虑的。未来的研究需要从整体上直接评估听觉刺激对自主神经唤醒和认知表现的影响。
