我们测试了优先效应作为回声-咔哒延迟和咔哒率在先行咔哒和滞后咔哒位置突然切换后的函数。以三种速率点击火车，1/秒。2/秒和4/秒，延迟在2到20毫秒之间，在消声室中呈现给受试者。在位置切换后的咔哒声持续时间为12秒，并在此期间评估回声咔哒声感知能力。听到的回声滴答声的数量是一个随延迟增加的单调函数。受试者报告说，在每次延迟后，不管频率如何，在一定数量的点击后，回声点击会“淡出”。这一结果被解释为持续的咔哒声产生的回声抑制的积累。前导咔哒声来自右侧时，对回声的抑制比来自左侧时更强。
The precedence effect was tested as a function of echo-click delay and click rate after an abrupt switch in location between leading and lagging clicks. Click trains at three rates, 1/sec. 2/sec, and 4/sec, with delays ranging between 2 and 20 msec, were presented to subjects in an anechoic chamber. Duration of the click train after the switch in location was 12 sec, and echo click perceptibility was assessed throughout this period. The number of echo clicks heard was an increasing monotonic function of delay. The subjects reported a "fade-out" of echo clicks after a set number of clicks at each delay, regardless of rate. This result was interpreted as a buildup in inhibition of echoes produced by the ongoing click train. Suppression of echoes was stronger when the leading click originated from the right side than from left side.
