Fifty subjects were tested to determine the point of intersection between two converging line segments. The angle between the two nonintersecting line segments was 30 degrees. The orientation of the display as well as the distance between the line segments and the point of their intersection was varied. Two-dimensional normal distributions can be accepted to describe the results - the 50 estimates of the point of intersection for each of the five displays presented. The parameters of these distributions are influenced mainly by two factors characterizing the test line segments: (1) proximity to one of the main axes - vertical and horizontal, and (2) distance to the actual point of intersection. The possible mechanisms that might be involved in the estimation of the point of intersection between two converging line segments are discussed.
五十名受试者参与测试，以确定两条汇聚线段的交点。两条不相交线段之间的夹角为30度。显示的方向以及线段与其交点之间的距离均有所变化。可以用二维正态分布来描述结果——即针对呈现的五种显示中的每一种，对交点的50次估计。这些分布的参数主要受表征测试线段的两个因素影响：(1) 与垂直和水平这两个主轴之一的接近程度，以及 (2) 到实际交点的距离。本文讨论了可能参与估计两条汇聚线段交点的潜在机制。
