为了有效地分析复杂场景，人类视觉系统根据场景中视觉元素的各种特征（例如颜色和运动）进行感知分组。尽管之前的研究表明这种分组可以基于单个特征（例如颜色或运动信息），但在这里我们表明视觉系统还基于两个特征的组合来执行场景分析。我们向受试者展示了向不同方向移动的红点和绿点的混合体。尽管颜色和运动信息之间的配对在点上是可变的（例如，一个红点向上移动，而另一个红点向右移动），但当随机配对的点两侧是具有一致颜色运动配对的附加点时，受试者对颜色运动配对的感知存在显着偏差。这些结果表明，视觉系统使用周围环境中的明确配对来解决颜色运动配对中的局部模糊性，展示了一种基于两种特征线索组合的新型场景分析。
To analyze complex scenes efficiently, the human visual system performs perceptual groupings based on various features (e.g., color and motion) of the visual elements in a scene. Although previous studies demonstrated that such groupings can be based on a single feature (e.g., either color or motion information), here we show that the visual system also performs scene analyses based on a combination of two features. We presented subjects with a mixture of red and green dots moving in various directions. Although the pairings between color and motion information were variable across the dots (e.g., one red dot moved upward while another moved rightward), subjects' perceptions of the color-motion pairings were significantly biased when the randomly paired dots were flanked by additional dots with consistent color-motion pairings. These results indicate that the visual system resolves local ambiguities in color-motion pairings using unambiguous pairings in surrounds, demonstrating a new type of scene analysis based on the combination of two featural cues.
