四个实验探索了时间过程可以被显性或隐性地表示和控制的假设。假设需要明确计时的任务是持续时间辨别、敲击和间歇性画圆圈。相反，假设在连续画圆过程中的定时控制不依赖于显式的时间表征；相反，时间控制是其他控制过程的紧急属性(即，定时被隐式控制)。在敲击和间歇画画任务上的时间一致性是相关的，在听觉时长辨别任务上，这两个任务上的表现与时间敏锐度相关。然而，这3项任务的时序变异性与连续画圆圈的时序变异性并不相关。这些结果支持了外显和内隐时间表征之间的假设区别。
Four experiments explored the hypothesis that temporal processes may be represented and controlled explicitly or implicitly. Tasks hypothesized to require explicit timing were duration discrimination, tapping, and intermittent circle drawing. In contrast, it was hypothesized that timing control during continuous circle drawing does not rely on an explicit temporal representation; rather, temporal control is an emergent property of other control processes (i.e., timing is controlled implicitly). Temporal consistency on the tapping and intermittent drawing tasks was related, and performance on both of these tasks was correlated with temporal acuity on an auditory duration discrimination task. However, timing variability of these 3 tasks was not correlated with timing variability of continuous circle drawing. These results support the hypothesized distinction between explicit and implicit temporal representations.
