Specialized, bimodal neural systems integrate visual and tactile information in the space near the hand. Here, we show that visuo-tactile representations allow attention to influence early perceptual processing, namely, figure-ground assignment. Regions that were reached toward were more likely than other regions to be assigned as foreground figures, and hand position competed with image-based information to bias figure-ground assignment. Our findings suggest that hand position allows attention to influence visual perceptual processing and that visual processes typically viewed as unimodal can be influenced by bimodal visuo-tactile representations.
专门的、双模态神经系统整合了手部附近空间的视觉和触觉信息。在这里,我们表明,视触表示允许注意影响早期的感知处理,即图形-背景分配。被指向的区域比其他区域更有可能被分配为前景图形,并且手的位置与基于图像的信息竞争以偏向图形-背景分配。我们的发现表明,手的位置允许注意影响视觉感知处理,并且通常被视为单模态的视觉过程可以受到双模态视触表示的影响。
