启动是一个有用的工具，可以用来确定以前的经历在什么情况下影响行为。以前，我们使用分层刺激，证明了选择性地注意到听觉刺激的一个时间尺度可以改善对重复的(与改变的)时间尺度的后续注意，即，我们展示了试验间听觉时间水平启动。在这里，我们扩展了这些结果，以解决水平启动是依赖于绝对时间信息还是相对时间信息。相对和绝对时间信息在听觉感知中都很重要：语音和音乐可以在不同的时间尺度上识别，但当呈现得太快或太慢时，听者就无法理解。我们首先证实了时间水平启动在新的时间尺度上的推广。其次，在多个时间尺度的背景下，我们发现时间水平启动主要基于相对的时间信息，而不是绝对的时间信息。这些发现是在期望和听力关系不变性的背景下讨论的。
Priming is a useful tool for ascertaining the circumstances under which previous experiences influence behavior. Previously, using hierarchical stimuli, we demonstrated that selectively attending to one temporal scale of an auditory stimulus improved subsequent attention to a repeated (vs. changed) temporal scale, i.e., we demonstrated inter-trial auditory temporal level-priming. Here, we have extended those results to address whether level-priming relied on absolute or relative temporal information. Both relative and absolute temporal information are important in auditory perception: speech and music can be recognized over various temporal scales, but become uninterpretable to a listener when presented too quickly or slowly. We first confirmed that temporal level-priming generalized over new temporal scales. Second, in the context of multiple temporal scales, we found that temporal level-priming operates predominantly on the basis of relative, rather than absolute, temporal information. These findings are discussed in the context of expectancies and relational invariance in audition.
