受试者执行重复的手动敲击任务，尝试匹配给定的听觉刺激脉冲速率，首先是脉冲可听（同步），然后关闭脉冲（继续）。 在不同的会话中，刺激间期（ISI）从175至825毫秒的范围内选择，步长为25毫秒，不同的ISI值以随机顺序呈现。 在这个范围的ISI条件下，反应间期（IRI）表现出交替的正偏差（太慢）和负偏差（太快）。 我们解释这种模式的偏见在一个离散的，或分类，定时机制在电机定时。 范畴时间产生可以被看作是对Wing（Wing & Kristofferson，1973a，1973b）的运动计时双过程模型中计时器概念的扩展，并且可能与Kristofferson（1980）提出的多时钟系统有关，后者用来解释持续时间辨别中变异性测量的范畴模式。
Subjects performed a repetitive manual tapping task, attempting to match a given rate of auditory stimulus pulses, first with the pulses audible (synchronization) and then with the pulses turned off (continuation). In different sessions, the interstimulus interval (ISI) was selected from the range 175 to 825 msec in steps of 25 msec, with different ISI values presented in a random order. Across this range of ISI conditions, interresponse intervals (IRIs) exhibited alternating positive bias (too slow) and negative bias (too fast). We interpret this pattern of bias in terms of a discrete, or categorical, timing mechanism in motor timing. Categorical time production can be viewed as extending our conception of the timekeeper in Wing's (Wing & Kristofferson, 1973a, 1973b) two-process model of motor timing and may be related to the system of multiple clocks proposed by Kristofferson (1980) to explain a categorical pattern of variability measures in duration discrimination.
