Previous research has demonstrated that auditory rhythms affect both movement and physiological functions. We hypothesized that the ecological sounds of human breathing can affect breathing more than artificial sounds of breathing, varying in tones for inspiration and expiration. To address this question, we monitored the breath duration of participants exposed to three conditions: (a) ecological sounds of breathing, (b) artificial sounds of breathing having equal temporal features as the ecological sounds, (c) no sounds (control). We found that participants' breath duration variability was reduced in the ecological sound condition, more than in the artificial sound condition. We suggest that ecological sounds captured the timing of breathing better than artificial sounds, guiding as a consequence participants' breathing. We interpreted our results according to the Theory of Event Coding, providing further support to its validity, and suggesting its possible extension in the domain of physiological functions which are both consciously and unconsciously controlled.
先前的研究表明，听觉节奏会影响运动和生理功能。我们假设，人类呼吸的自然声音比人工呼吸声音对呼吸的影响更大，人工呼吸声音的吸气和呼气音调不同。为了解决这个问题，我们监测了处于三种条件下的参与者的呼吸时长：(a) 呼吸的自然声音；(b) 具有与自然声音相同时间特征的人工呼吸声音；(c) 无声音（对照）。我们发现，与人工声音条件相比，在自然声音条件下参与者的呼吸时长变异性降低。我们认为，自然声音比人工声音能更好地捕捉呼吸的时机，从而引导参与者的呼吸。我们根据事件编码理论来解释我们的结果，为其有效性提供了进一步支持，并表明其可能在有意识和无意识控制的生理功能领域得到扩展。
