Modality effects in rhythm processing were examined using a tempo judgment paradigm, in which participants made speeding-up or slowing-down judgments for auditory and visual sequences. A key element of stimulus construction was that the expected pattern of tempo judgments for critical test stimuli depended on a beat-based encoding of the sequence. A model-based measure of degree of beat-based encoding computed from the pattern of tempo judgments revealed greater beat sensitivity for auditory rhythms than for visual rhythms. Visual rhythms with prior auditory exposure were more likely to show a pattern of tempo judgments similar to that for auditory rhythms than were visual rhythms without prior auditory exposure, but only for a beat period of 600 msec. Slowing down the rhythms eliminated the effect of prior auditory exposure on visual rhythm processing. Taken together, the findings in this study support the view that auditory rhythms demonstrate an advantage over visual rhythms in beat-based encoding and that the auditory encoding of visual rhythms can be facilitated with prior auditory exposure, but only within a limited temporal range. The broad conclusion from this research is that "hearing visual rhythms" is neither obligatory nor automatic, as was previously claimed by Guttman, Gilroy, and Blake (2005).
使用节奏判断范式研究了节奏处理中的模态效应，在该范式中，参与者对听觉和视觉序列进行加速或减速判断。刺激构建的一个关键要素是，关键测试刺激的预期节奏判断模式取决于序列基于节拍的编码。根据节奏判断模式计算出的基于节拍编码程度的模型测量结果显示，听觉节奏比视觉节奏对节拍更敏感。与没有先前听觉暴露的视觉节奏相比，有先前听觉暴露的视觉节奏更有可能表现出与听觉节奏相似的节奏判断模式，但仅在节拍周期为600毫秒时如此。放慢节奏消除了先前听觉暴露对视觉节奏处理的影响。综合来看，本研究的结果支持以下观点：在基于节拍的编码中，听觉节奏比视觉节奏具有优势，并且先前的听觉暴露可以促进视觉节奏的听觉编码，但仅在有限的时间范围内。这项研究的广泛结论是，“听到视觉节奏”既不是如古特曼、吉尔罗伊和布莱克（2005年）之前所声称的那样是必然的，也不是自动的。
