Listeners detected interaural differences of time in trains of high-frequency clicks. The manipulated variables were the number of clicks in the train and the period between clicks. Thresholds were compared to an optimal integrator, where the binaural information accrued from each click in the stimulus train is equivalent. In agreement with data reported in the past, integration is optimal only when the period between clicks exceeds approximately 10 ms and when the duration of the entire stimulus train is less than about 250 ms. The first constraint represents a limitation due to a form of "binaural adaptation" and the second is due to a limited "integration period."
听众能够检测到高频滴答声序列中的双耳时间差异。操作变量为序列中的滴答声数量以及滴答声之间的间隔时间。将阈值与一个最优积分器进行比较,在最优积分器中,从刺激序列中的每个滴答声积累的双耳信息是等效的。与过去报道的数据一致,只有当滴答声之间的间隔超过约10毫秒且整个刺激序列的持续时间小于约250毫秒时,积分才是最优的。第一个限制是由于一种“双耳适应”形式导致的,第二个限制是由于“积分周期”有限。
