时间预期依赖于不同的预测信息，如规律的节奏和符号提示，将注意力引导到未来的某个时刻，以优化行为。然而，是否存在差异的时间预期驱动的规则的节奏和象征性的线索还没有明确确立。在这项研究中，20名参与者执行了两项时间预期任务，其中节奏线索或符号线索表明（70%的预期）目标将在500 ms（短），1，500 ms（中）或2，500 ms（长）的间隔后出现。我们发现，在短时间内，节奏线索任务比符号线索任务的提示效果更大，这表明节奏线索在提高成绩方面更有效。此外，在较长的时间间隔内没有发现显著差异，反映了两种形式的时间期望之间的行为差异可能会随着时间间隔的增加而减少。因此，我们推测，由节奏线索驱动的时间期望不同，由符号线索驱动的时间期望仅在有限的时间范围内，然而，这两种形式的时间期望的潜在机制的趋势变得更加相似，随着时间尺度的增加。
Temporal expectation relies on different predictive information, such as regular rhythms and symbolic cues, to direct attention to a future moment in time to optimize behaviour. However, whether differences exist between temporal expectations driven by regular rhythms and symbolic cues has not been clearly established. In this study, 20 participants performed two temporal expectation tasks in which a rhythmic cue or a symbolic cue indicated (70% expected) that the target would appear after an interval of 500 ms (short), 1,500 ms (medium), or 2,500 ms (long). We found larger cueing effects for the rhythmic cued task than for the symbolic cued task during the short interval, indicating that rhythmic cues were more effective in improving performance. Furthermore, no significant difference was found during the longer interval, reflect that the behavioural differences between the two forms of temporal expectations were likely to diminish as the time interval increased. Thus, we speculate that the temporal expectation driven by rhythmic cues differs from that driven by symbolic cues only in the limited time range; however, the mechanisms underlying the two forms of temporal expectations trend to become more similar over increasing temporal scales.
