物体特征可以通过各种物理属性或图形线索的差异来表现。在这项研究中，我们提供的证据表明，从不同的图形线索产生的运动信号可以结合起来，产生一个连贯的移动（异质线索）模式的感知。此外，是真实的，为连贯的线索模式，相似性沿着尺寸的对比度（我们介绍的对比度等价的想法）和空间频率决定是否连贯的运动被感知。这些结果是根据最近的生理证据表明，在皮层视觉区MT中的许多神经元的方向选择性是不变的，在图形的线索，定义了移动的刺激（“形式线索不变性”）的变化。
Object features can be made manifest by differences in a variety of physical attributes or figural cues. In this study we provide evidence that motion signals arising from different figural cues can be combined to produce a percept of a coherently moving (heterogeneous-cue) pattern. Moreover, as is true for homogeneous-cue patterns, similarity along the dimensions of contrast (we introduce the idea of contrast equivalence) and spatial frequency determines whether coherent motion is perceived. These results are in accordance with recent physiological evidence demonstrating that directional selectivity of many neurons in cortical visual area MT is invariant over changes in the figural cue that defines the moving stimulus (“form-cue invariance”).
