Visual sensitivity was measured during vergence eye movements in order to determine whether a suppression of vision similar to that associated with saccades is also present during vergence. Suppression was evaluated psychophysically by determining sensitivity to briefly presented, full-field decrements of light in a Ganzfeld. Subjects were rougly 0.5 log unit less sensitive when stimuli were presented at the beginning of a 2-3 deg convergent or divergent eye movement, than during steady fixation. Thus, the concept of saccadic suppression must be broadened to include visual suppression that also accompanies nonsaccadic eye movements. These results support the hypothesis that vision is affected by signals that accompany initiation of oculomotor activity.
在双眼运动过程中测量视觉敏感度，以确定在双眼运动期间是否也存在类似于与扫视相关的视觉抑制。通过确定在全视野条件下对短暂呈现的光强递减的敏感度，以心理物理学方法评估抑制情况。当刺激在2-3度的会聚或发散眼动开始时呈现时，受试者的敏感度比在稳定注视期间大约低0.5个对数单位。因此，扫视抑制的概念必须拓宽，以包括非扫视眼动时伴随的视觉抑制。这些结果支持了以下假设，即视觉受动眼活动启动时伴随的信号影响。
