最近我们发现，在平滑追踪眼动（SPEMs）过程中，对色度和高空间频率亮度刺激的敏感性得到增强。在这里，我们研究了这种增强是否是慢眼运动的一般特性。除了SPEM，还有另外两类眼球运动在相似的眼速范围内运作：光动性眼球震颤（OKN）是由宽视场视觉运动引起的快速和缓慢交替眼球运动的反射模式，而前庭眼反射（VOR）在头部运动期间稳定凝视。在自然环境中，这三种类型的眼球运动协同作用，在自我和物体运动时允许清晰的中央视觉。为了测试在所有这些眼动过程中是否会出现同样的色敏性改善，我们测量了在OKN期间人类对色和亮度线刺激的检测性能，以及在相同速度下VOR和SPEM期间人类对对比敏感度的检测性能。为了比较，在注视过程中测试了相同任务的表现。在OKN慢期，我们发现与SPEM相似的色度检出率增强，而VOR未观察到色度检出率增强。这一结果表明慢相OKN和SPEM有相似之处，与VOR不同。
Recently we showed that sensitivity for chromatic- and high-spatial frequency luminance stimuli is enhanced during smooth-pursuit eye movements (SPEMs). Here we investigated whether this enhancement is a general property of slow eye movements. Besides SPEM there are two other classes of eye movements that operate in a similar range of eye velocities: the optokinetic nystagmus (OKN) is a reflexive pattern of alternating fast and slow eye movements elicited by wide-field visual motion and the vestibulo-ocular reflex (VOR) stabilizes the gaze during head movements. In a natural environment all three classes of eye movements act synergistically to allow clear central vision during self- and object motion. To test whether the same improvement of chromatic sensitivity occurs during all of these eye movements, we measured human detection performance of chromatic and luminance line stimuli during OKN and contrast sensitivity during VOR and SPEM at comparable velocities. For comparison, performance in the same tasks was tested during fixation. During the slow phase of OKN we found a similar enhancement of chromatic detection rate like that during SPEM, whereas no enhancement was observable during VOR. This result indicates similarities between slow-phase OKN and SPEM, which are distinct from VOR.
