跨模式对知觉组织的影响是通过一个结合了听觉流分离刺激和视觉表观运动模拟的显示器来展示的。这两种现象都会引起对1个或2个物体的感知，这取决于刺激的呈现速度。在较慢的速率下，1个对象被感知，而2个对象以较快的速率被感知。受试者指出了在每个通道中发生知觉转移的连续刺激之间的刺激起始异步性(SOA)。然后同时呈现视觉和听觉刺激，受试者对目标通道序列做出反应。对于非靶刺激，使用了两个组间分离。根据在目标序列的流分离点分别代表1个和2个目标的受试者S校准数据来选择距离。当非目标刺激指示2个目标而不是代表1个目标时，在较大的SOA处发生分离。对于视觉和听觉目标序列都是如此。
Cross-modal influences on perceptual organization were demonstrated using a display that combined a stimulus for auditory stream segregation with its visual apparent movement analog. Both phenomena give rise to the perception of either 1 or 2 objects, depending on the rate of presentation of the stimuli. At slower rates, 1 object is perceived, while 2 are perceived at faster rates. Subjects indicated the stimulus onset asynchrony (SOA) between successive stimuli at which the perceptual shift occurred in each modality. Then visual and auditory stimuli were presented concurrently and subjects responded to the target modality sequence. Two intergroup separations for the nontarget stimuli were used. Distances were chosen, based on the subject''s calibration data, which represented 1 and 2 objects, respectively, at the stream segregation point for the target sequence. Segregation occurred at larger SOA when the nontarget stimulation indicated 2 objects than when it represented one. This was true for both visual and auditory target sequences.
