Fixation disparity was measured psychophysically when subjects viewed a central fusion stimulus at 50 cm distance. Reducing luminance and increasing target blur resulted in an exophoric shift of fixation disparity. Fixation disparity was significantly more exophoric in subjects with distant dark vergence, i.e. the resting position of vergence. This was true for the bright and sharp target, as well as for targets impaired by blurring or dimming. These results are interpreted as a bias of fixation disparity towards the individual resting position of vergence not only for degraded stimuli but also for strong central fusion stimuli.
当受试者在50厘米距离观看中央融合刺激物时，通过心理物理学方法测量注视差异。降低亮度并增加目标模糊度会导致注视差异出现外隐斜偏移。在具有远距离暗聚散（即聚散的静止位置）的受试者中，注视差异显著更偏向于外隐斜。对于明亮清晰的目标以及因模糊或变暗而受损的目标而言都是如此。这些结果被解释为，不仅对于退化刺激，而且对于强烈的中央融合刺激，注视差异都偏向于个体的聚散静止位置。
