扩展了先前关于注意力跨听觉和视觉形态转移的证据，而没有混淆起源于不同位置的两种形态(Turatto等人。2002)，我们研究了听觉和触觉通道之间的注意转移，以及触觉和视觉通道之间的注意转移。两个刺激(S1和S2)，无论是相同的或不同的模式，都来自相同的空间源，并由可变的时间间隔分开。S1与任务无关，而S2需要快速辨别。结果表明，只要S1和S2之间的时间滞后足够短，以至于在S2发出之前没有时间切换注意，那么通道转换是有害的，不受刺激通道的影响。我们观察到自动的、通道驱动的注意力捕获，同通道试验比交叉通道试验导致更快的反应时间。目前的结果不能用空间伪影、反应启动或标准转移来解释，而是被解释为空间无关的跨感觉通道注意转移的结果。
Extending previous evidence for attentional shifts across auditory and visual modalities without the confound of the two modalities originating at different locations (Turatto et al. 2002), we investigated attention shifts between auditory and tactile modalities, and between tactile and visual modalities. Two stimuli (S1 and S2), either in the same or in different modalities, were delivered from the same spatial source and were separated by a variable temporal gap. S1 was task irrelevant, whereas S2 required a speeded discrimination. Results showed that modality switching is detrimental independently of the stimulated modality as long as the temporal lag between S1 and S2 is short enough that there is not time to switch attention before S2 is delivered. We observed automatic, modality-driven, attentional capture, with ipsimodal trials leading to faster response times than crossmodal trials. The present results cannot be accounted for by spatial artifacts, response priming or criterion shifts, and are interpreted as the consequence of a space-independent attentional shift across sensory modalities.
