一个开创性的时间估计的注意模型预测，主观持续时间将与给予时间加工的注意力的量呈正相关。这一预测在预期条件下是成立的，在这种情况下，人们被预先警告，将要求作出时间判断，而不是追溯条件，即要求在相关期间之后作出这种判断，而不需要任何事先警告。在三个实验中，使用了注意力分享的方法。受试者被要求控制他们对双重任务范例中的一个或另一个部分的注意力。第一个实验包括词语分类和时长再现。以下实验基于信号检测理论，要求在视觉(实验2)或听觉(实验3)通道中辨别单个刺激的持续时间和强度。研究结果表明，当注意由被试直接控制时，被试的主观持续时间随着对时间任务的注意减少而缩短。讨论了这些结果对内部定时器可能存在的影响。
A seminal attentional model of time estimation predicts that subjective duration will be positively correlated to the amount of attention given to temporal processing. This prediction holds under prospective conditions, in which one is forewarned that judgements of time will be asked, in contrast to retrospective conditions, in which such judgments are required after the relevant period without any prior warning. In three experiments, an attention-sharing method was used. Subjects were asked to control the amount of attention that they devoted to one or the other component of a dual-task paradigm. The first experiment involved word categorization and reproduction of duration. The following experiments, based on signal detection theory, required discrimination of both the duration and the intensity of a single stimulus, in the visual (Experiment 2) or the auditory (Experiment 3) modality. The results indicate that when the attention is directly controlled by the subject, the subjective duration shortens as the amount of attention devoted to the temporal task diminishes. The implications of these results for the possible existence of an internal timer are considered.
