使用目标选择范例研究了用于平滑追踪和扫视眼球运动的颜色和亮度的视觉处理。在两个实验中，刺激沿着颜色和亮度维度变化，并在追踪和扫视中比较更显着目标的选择。最初的追求偏向于亮度分量的方向，而眼跳则显示出对颜色的相对偏好。早期对亮度的追求反应通常会在后来的扫视中逆转为颜色。在两个对照实验中获得的观察者对刺激显着性的感知判断明显偏向于亮度。感知数据中的这种选择偏差意味着最初的短延迟追求反应与感知判断一致。相比之下，眼跳的潜伏期比追踪更长，它似乎不遵循显着性的感知判断，而是表现出对颜色更强的相对偏好。目标选择中的这些显着差异意味着追踪和扫视眼球运动的目标选择过程对颜色和亮度刺激使用明显不同的权重。
Visual processing of color and luminance for smooth pursuit and saccadic eye movements was investigated using a target selection paradigm. In two experiments, stimuli were varied along the dimensions color and luminance, and selection of the more salient target was compared in pursuit and saccades. Initial pursuit was biased in the direction of the luminance component whereas saccades showed a relative preference for color. An early pursuit response toward luminance was often reversed to color by a later saccade. Observers' perceptual judgments of stimulus salience, obtained in two control experiments, were clearly biased toward luminance. This choice bias in perceptual data implies that the initial short-latency pursuit response agrees with perceptual judgments. In contrast, saccades, which have a longer latency than pursuit, do not seem to follow the perceptual judgment of salience but instead show a stronger relative preference for color. These substantial differences in target selection imply that target selection processes for pursuit and saccadic eye movements use distinctly different weights for color and luminance stimuli.
