Robust visual attentional responses are produced by the sudden onset of a visual cue, but the properties of cues that best elicit an attentional response are not fully known. We used the line-motion illusion (Hikosaka et al., 1991) to investigate the optimal cue properties that evoke visual attention. We found that visual attention is driven primarily by the luminance contrast of the cue. Furthermore, by manipulating the spatial, chromatic, and contrast properties of cues, we found that magnocellular (M) stream biased cues always override the response to parvocellular (P) stream biased cues, even when the P stream biased cues are presented first. Our data suggest that cues that preferentially excite the M pathway predominantly capture visual attention.
视觉线索的突然出现会产生强烈的视觉注意力反应，但能最有效地引发注意力反应的线索特性尚未完全明确。我们利用线运动错觉（日高坂等人，1991年）来研究引发视觉注意力的最佳线索特性。我们发现，视觉注意力主要由线索的亮度对比度驱动。此外，通过操纵线索的空间、颜色和对比度特性，我们发现大细胞（M）通路偏向的线索总是会压倒对小细胞（P）通路偏向线索的反应，即使P通路偏向的线索先呈现。我们的数据表明，优先激发M通路的线索主要捕获视觉注意力。
