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.
四项实验探究了时间进程可能以显性或隐性方式被表征和控制这一假设。被假定需要显性计时的任务包括时长辨别、敲击以及间歇性画圈。相比之下，假定连续画圈过程中的计时控制并不依赖于显性的时间表征；相反，时间控制是其他控制过程的一种涌现属性（即计时是被隐性控制的）。敲击任务和间歇性画圈任务的时间一致性是相关的，并且这两项任务的表现都与听觉时长辨别任务中的时间敏锐度相关。然而，这三项任务的计时变异性与连续画圈的计时变异性并无关联。这些结果支持了关于显性和隐性时间表征之间假定差异的观点。
