我们研究了通常在空间相容性任务中观察到的跨通道一致性效应是否也会影响基于区分刺激身份的任务的表现（即，非空间维度）。在一个4-选择节奏辨别任务中，向参与者的眼睛、耳朵和/或手呈现两种节奏。刺激身份和刺激方式正交变化。当目标和干扰物节律以不同的感觉模态呈现时，在所有条件下都观察到显著的跨模态一致性效应（即，在不一致的干扰试验中的表现比一致的干扰试验更容易出错）。与以往的研究结果相比，这些跨通道干扰效应既不是基于刺激的空间兼容性，也不是基于刺激身份的抽象语义匹配，而是基于目标节奏的身份。有趣的是，作为目标模态的函数，跨模态一致性效应的大小不同，但不受干扰物模态的影响。(C)2010爱思唯尔有限公司版权所有。
We investigated whether the crossmodal congruency effect, normally observed in spatial compatibility tasks, would also affect performance on a task based on discriminating stimulus identity (i.e., a non-spatial dimension). Two rhythms were presented to participants' eyes, ears, and/or hands in a 4-alternative rhythm discrimination task. Stimulus identity and stimulus modality were varied orthogonally. When the target and distractor rhythms were presented in different sensory modalities, significant crossmodal congruency effects were observed in all conditions (i.e., performance on the incongruent distractor trials was significantly more error-prone than on the congruent distractor trials). In contrast to the results of previous studies, these crossmodal distractor effects were neither based on the spatial compatibility of the stimuli nor on an abstract semantic matching of stimulus identity, but instead on the identity of the target rhythm. Intriguingly, the magnitude of the crossmodal congruency effects differed as a function of the target modality, but were unaffected by the modality of the distractor. (C) 2010 Elsevier B.V.
