The reaction time (RT) to an auditory stimulus was measured in 27 subjects during spontaneous breathing and during controlled breathing, which consisted of maintaining a set inspiratory duration. During spontaneous breathing, reaction times were unrelated to the time the stimulus was delivered during the breathing cycle. During controlled breathing, reaction times were longer than during spontaneous breathing. Peak reaction times were observed at the transition from inspiration to expiration. After the end of controlled breathing, reaction times gradually became shorter until they reached their initial level. The findings are discussed in terms of varying allocation of attentional resources to breathing. It is argued that probe RT methodology provides a suitable means for investigating attentional control of breathing.
在27名受试者进行自主呼吸和控制呼吸(包括保持设定的吸气持续时间)期间,测量了对听觉刺激的反应时间(RT)。在自主呼吸期间,反应时间与呼吸周期中刺激传递的时间无关。在控制呼吸期间,反应时间比自主呼吸期间更长。在从吸气到呼气的转换过程中观察到了峰值反应时间。在控制呼吸结束后,反应时间逐渐变短,直到达到初始水平。根据对呼吸的注意力资源分配变化对这些发现进行了讨论。有人认为,探测反应时方法为研究呼吸的注意力控制提供了一种合适的手段。
