人类受试者表示，当一个短暂暴露的光主观上是直向前在不同程度的不对称收敛。方向知觉明显表现出系统的不稳定性。从恒定的偏离取决于非对称收敛的程度，增加非对称收敛的增加。对不稳定性的来源进行了调查。不稳定性显然是由于眼睛位置的配准不良和视网膜位置刺激的配准不良的组合。由于视网膜区域的配准不良的错误是恒定的，无论测试目标的位置，而由于眼睛位置的配准不良的错误是依赖于不对称收敛的程度。讨论了一种考虑视觉方向的模型。
Human subjects indicated when a briefly exposed light was subjectively straight ahead during various degrees of asymmetric convergence. The perception of direction apparently exhibited systematic underconstancy. The departures from constancy were dependent upon the degree of asymmetric convergence, increasing as asymmetric convergence increased. The source of underconstancy was investigated. The underconstancy was apparently due to a combination of the misregistration of eye position and misregistration of the retinal location stimulated. The errors due to misregistration of retinal area were constant regardless of location of the test target, while the errors due to misregistration of eye position were dependent upon the degree of asymmetric convergence. A taking-into-account model of visual direction was discussed.
