Movements of the chest wall during the interval between an acoustic stimulus and the subject's vocal response were examined and timed in eight normal males. The reaction-time interval was divisible into two phases, a latency period with duration independent on chest wall status at the time of stimulus and an adjustment period during which the rib cage and abdomen usually moved oppositionally to achieve a prephonatory postural set. The time required for this adjustment varied significantly with lung volume, but was independent of the ventilatory phaze previously in progress.
对8名正常男性在声音刺激与受试者发声反应之间的间隔期内胸壁的运动进行了检查并计时。反应时间间隔可分为两个阶段，一个是潜伏期，其持续时间与刺激时的胸壁状态无关，另一个是调整期，在此期间胸廓和腹部通常反向运动以达到发声前的姿势准备。这种调整所需的时间随肺容量有显著变化，但与先前进行的通气阶段无关。
