Here we present two experiments investigating the implicit orienting of attention over time by entrainment to an auditory rhythmic stimulus. In the first experiment, participants carried out a detection and discrimination tasks with auditory and visual targets while listening to an isochronous, auditory sequence, which acted as the entraining stimulus. For the second experiment, we used musical extracts as entraining stimulus, and tested the resulting strength of entrainment with a visual discrimination task. Both experiments used reaction times as a dependent variable. By manipulating the appearance of targets across four selected metrical positions of the auditory entraining stimulus we were able to observe how entraining to a rhythm modulates behavioural responses. That our results were independent of modality gives a new insight into cross-modal interactions between auditory and visual modalities in the context of dynamic attending to auditory temporal structure.
在此，我们展示了两项实验，这些实验通过与听觉节奏刺激同步来研究随时间推移注意力的内隐定向。在第一个实验中，参与者在听一个等时的听觉序列（作为同步刺激）的同时，执行针对听觉和视觉目标的检测与辨别任务。在第二个实验中，我们使用音乐片段作为同步刺激，并通过视觉辨别任务来测试由此产生的同步强度。两项实验均将反应时间作为因变量。通过在听觉同步刺激的四个选定节拍位置上操纵目标的出现情况，我们能够观察到与节奏同步如何调节行为反应。我们的结果与模态无关，这为在动态关注听觉时间结构的背景下，听觉和视觉模态之间的跨模态交互提供了新的见解。
