Attentional constraints in the perceptual analysis of motion direction were examined using two independent paradigms: redundant target visual search and the analysis of fluctuations in discrimination accuracy at threshold. Results from both methods implied that directions of object motion are analyzed in parallel when those motions are translations, independent of the observer's line of sight. The registration of rotation direction appears to be subject to a qualitatively different protocol, one that is highly capacity limited and serial-like. These results suggest that scene-based descriptions, as opposed to image-based descriptions of motion, mediate the allocation of attention.
冗余目标视觉搜索和阈值处辨别准确性波动分析。两种方法的结果都表明，当物体运动为平移时，运动方向是并行分析的，与观察者的视线无关。旋转方向的登记似乎遵循一种性质不同的模式，一种容量高度受限且类似串行的模式。这些结果表明，与基于图像的运动描述相反，基于场景的描述介导了注意力的分配。
