摘要: <正> 我們的前一个实驗研究曾經証明:輻合在30米左右的距离判断中仍起着一定作用,这就与前人认为輻合只在20米范围內起作用的結論有所不同。我們在前一个实驗中利用偏光鏡使两眼分别看两个相同的标准刺激物,通过双眼融合作用知觉成一个刺激物,然后变化两个标准刺激物间的水平距离便能改变輻合角度(如图1)。但是在計算

Abstract: The relationship between convergence and distance judgment, with interocular distance as a variable, was experimentally studied. 32 persons with interocular distances ranging from 56 mm to 70mm served as observers. Two conditions were used: (1) Convergence was controlled by means of polaroids, so as to produce a fuscd image artificially at different distances, while the physical distance of the stimuli remained constant; (2) Convergence varied in a natural manner with the physical distances of the stimuli.The results showed:(1) Convergence plays an important role in distance perception. In condition I) distance judgtnents fall very near to the calculated values of the convergence distances. In condition 2) distance can be perceived quite accurately by using convergence cues within a certain distance range.(2) Under our experimental conditions, convergence serves as a cue for distance as far as 35—45 metres, which is much greater than the commonly held opinion of 20 metres.(3) Observers with different interocular distances showed difference in the accuracy of distance judgments. The greater the interocular distance the more accurate is the judgment of distance.
