当被试对多模态视听刺激进行判断时，听觉信息在时间判断中占主导地位，而视觉信息在空间判断中占主导地位。然而，时间判断并不独立于空间特征。例如，在Kappa效应中，当两个标记刺激来自空间上遥远的来源而不是来自同一来源时，它们之间的时间间隔显得更长。我们研究了伴随无关视觉刺激的听觉标记的Kappa效应。标记的空间来源是不同的，使得它们在不同的模态中是一致的或不一致的。在两个实验中，我们证明了视觉刺激的空间布局影响感知听觉间隔时间。这种效果发生，虽然视觉刺激被指定为任务无关的持续时间再现任务在实验1中，甚至当视觉刺激不包含足够的时间信息，以执行两个时间间隔比较任务在实验2中。我们的结论是，视觉和听觉标记刺激被整合到一个组合的多感官刺激，包含时间以及任务无关的空间方面的刺激。通过这种多感觉整合过程，视觉空间信息甚至影响了通常由听觉模态主导的时间判断。
When participants judge multimodal audiovisual stimuli, the auditory information strongly dominates temporal judgments, whereas the visual information dominates spatial judgments. However, temporal judgments are not independent of spatial features. For example, in the kappa effect, the time interval between two marker stimuli appears longer when they originate from spatially distant sources rather than from the same source. We investigated the kappa effect for auditory markers presented with accompanying irrelevant visual stimuli. The spatial sources of the markers were varied such that they were either congruent or incongruent across modalities. In two experiments, we demonstrated that the spatial layout of the visual stimuli affected perceived auditory interval duration. This effect occurred although the visual stimuli were designated to be task-irrelevant for the duration reproduction task in Experiment 1, and even when the visual stimuli did not contain sufficient temporal information to perform a two-interval comparison task in Experiment 2. We conclude that the visual and auditory marker stimuli were integrated into a combined multisensory percept containing temporal as well as task-irrelevant spatial aspects of the stimulation. Through this multisensory integration process, visuospatial information affected even temporal judgments, which are typically dominated by the auditory modality.
