最近的研究表明，时间定向需要控制注意力（卡皮齐等人，）。然而，目前有争议的时间准备定期节奏的指导下，是否也需要产生内源性的时间预期，或者更确切地说，涉及一种独立于执行控制过程的机制。我们在两个不同的实验中使用双任务范式来研究这个问题。在实验1中，单任务条件下测量的反应时间，以响应由一个规则或不规则的听觉节奏之前的听觉刺激的发作。双任务条件还包括一个工作记忆任务，需要心理计数和更新。在实验二中，同时工作记忆任务是斯滕贝格任务的一个变体。我们假设，如果时间准备诱导的节奏不涉及执行处理，它不会受到干扰的同时工作记忆任务。结果表明，在两个实验中，被试都能在有规律的节奏基础上预测目标出现的时刻，而且这种能力能够抵抗双重任务条件的干扰。这一发现支持的时间准备诱导的节奏，相反，时间定向，不需要执行控制的资源。
It has been recently shown that temporal orienting demands controlled attention (Capizzi et al.,). However, there is current debate on whether temporal preparation guided by regular rhythms also requires the generation of endogenous temporal expectancies or rather involves a mechanism independent of executive control processes. We investigated this issue by using a dual-task paradigm in two different experiments. In Experiment 1, the single-task condition measured reaction time to respond to the onset of an auditory stimulus preceded by either a regular or an irregular auditory rhythm. The dual-task condition additionally included a working memory task, which demanded mental counting and updating. In Experiment 2, the simultaneously WM task was a variant of the Sternberg Task. We hypothesized that, if temporal preparation induced by rhythms did not involve executive processing, it would not be interfered by the simultaneous working memory task. The results showed that participants could anticipate the moment of target onset on the basis of the regular rhythm and, more important, this ability resisted the interference from the double task condition in both experiments. This finding supports that temporal preparation induced by rhythms, in contrast to temporal orienting, does not require resources of executive control.
