Three experiments were conducted examining unimodal and crossmodal effects of attention to motion. Horizontally moving sounds and dot patterns were presented and participants' task was to discriminate their motion speed or whether they were presented with a brief gap. In Experiments 1 and 2, stimuli of one modality and of one direction were presented with a higher probability (p = .7) than other stimuli. Sounds and dot patterns moving in the expected direction were discriminated faster than stimuli moving in the unexpected direction. In Experiment 3, participants had to respond only to stimuli moving in one direction within the primary modality, but to all stimuli regardless of their direction within the rarer secondary modality. Stimuli of the secondary modality moving in the attended direction were discriminated faster than were oppositely moving stimuli. Results suggest that attending to the direction of motion affects perception within vision and audition, but also across modalities.
进行了三项实验，研究对运动的注意的单通道和跨通道效应。呈现水平移动的声音和点模式，参与者的任务是辨别它们的运动速度或是否出现短暂间隙。在实验1和实验2中，一种模态和一个方向的刺激呈现概率（p = 0.7）高于其他刺激。预期方向移动的声音和点模式比意外方向移动的刺激辨别得更快。在实验3中，参与者必须仅对主要模态中一个方向移动的刺激做出反应，但对较罕见的次要模态中所有方向的刺激都要做出反应。次要模态中朝被注意方向移动的刺激比相反方向移动的刺激辨别得更快。结果表明，注意运动方向不仅会影响视觉和听觉内的感知，还会影响跨模态的感知。
