Auditory rhythms create powerful expectations for the listener. Rhythmic cues with the same temporal structure as subsequent sentences enhance processing compared with irregular or mismatched cues. In the present study, we focus on syllable detection following matched rhythmic cues. Cues were aligned with subsequent sentences at the syllable (low-level cue) or the accented syllable (high-level cue) level. A different group of participants performed the task without cues to provide a baseline. We hypothesized that unaccented syllable detection would be faster after low-level cues, and accented syllable detection would be faster after high-level cues. There was no difference in syllable detection depending on whether the sentence was preceded by a high-level or low-level cue. However, the results revealed a priming effect of the cue that participants heard first. Participants who heard a high-level cue first were faster to detect accented than unaccented syllables, and faster to detect accented syllables than participants who heard a low-level cue first. The low-level-first participants showed no difference between detection of accented and unaccented syllables. The baseline experiment confirmed that hearing a low-level cue first removed the benefit of the high-level grouping structure for accented syllables. These results suggest that the initially perceived rhythmic structure influenced subsequent cue perception and its influence on syllable detection. Results are discussed in terms of dynamic attending, temporal context effects, and implications for context effects in neural entrainment.

您首先听到的就是所得到的:初始的音调提示表示可调节句子处理中的音节检测

听觉节奏对听众产生强烈的期望。与不规则或不匹配的提示相比,具有与后续句子相同的时间结构的节奏提示可以增强处理能力。在本研究中,我们专注于匹配后的音节检测有节奏的提示。在音节(低级提示)或重读音节(高级提示)级别将提示与后续句子对齐。另一组参与者在没有提示的情况下执行了任务以提供基线。我们假设,未重读音节检测在出现低水平提示后会更快,而重读音节检测在出现高水平提示后会更快。在音节检测上没有区别,这取决于句子之前是高阶提示还是低阶提示。但是,结果表明参与者首先听到的提示具有启动作用。。与没有重音节的音节相比,首先听到高音节的音节的发音速度更快,与没有重音节的音节音色识别速度更快。低水平优先参与者在重音节和未重音节的检测之间没有差异。基线实验证实,听到低级提示会首先消除重音节的高级分组结构的好处。这些结果表明,最初感知的节奏结构会影响随后的提示感知及其对音节检测的影响。根据动态参与,时间情境效应以及对神经训练中情境效应的影响对结果进行了讨论。
