在众所周知的听觉位置的视觉偏差（别名腹语效应）中，在不同位置呈现的听觉和视觉事件看起来更接近，只要呈现同步。在这里，我们考虑的可能性的匡威现象：跨模态的吸引力的时间维度上的空间接近的条件。参与者判断声脉冲和闪光的发生顺序，分别通过不同的刺激起始时间间隔（SOA）和在相同或不同的位置提供。介绍组织使用随机混合的心理物理楼梯，SOA逐渐减少，直到达到一个点的不确定性。这一点是在更长的SOA与声音在相同的正面位置的闪光比在不同的地方，表明明显的时间分离是有效的第一个条件更长。再加上最近获得的一个类似的情况下的斗争视觉差异，这一结果支持的观点，在这种情况下，输入的时间和空间布局在一定程度上互换的作用，在配对操作的基础上的跨通道的相互作用。(C)2003 Elsevier Science B.V.保留所有权利。
In the well-known visual bias of auditory location (alias the ventriloquist effect), auditory and visual events presented in separate locations appear closer together, provided the presentations are synchronized. Here, we consider the possibility of the converse phenomenon: crossmodal attraction on the time dimension conditional on spatial proximity. Participants judged the order of occurrence of sound bursts and light flashes, respectively, separated in time by varying stimulus onset asynchronies (SOAs) and delivered either in the same or in different locations. Presentation was organized using randomly mixed psychophysical staircases, by which the SOA was reduced progressively until a point of uncertainty was reached. This point was reached at longer SOAs with the sounds in the same frontal location as the flashes than in different places, showing that apparent temporal separation is effectively longer in the first condition. Together with a similar one obtained recently in a case of tactile-visual discrepancy, this result supports a view in which timing and spatial layout of the inputs play to some extent inter-changeable roles in the pairing operation at the base of crossmodal interaction.
