区分两个相邻呈现的光盘的大小的能力被认为是光盘大小和其呈现的视网膜轨迹的函数。要求学生报告当两者一起简要介绍时，比较椎间盘是否与标准椎间盘大小相同或更大。结果表明，50%差异辨别所需的和与盘的大小无关，并且在约30弧秒处是恒定的。对于周边介绍，jnd被发现以线性方式增加偏心的介绍。所获得的结果和周边视力数据之间的比较，据推测，在这两种情况下，涉及类似的过程。
Ability to discriminate between the sizes of two adjacently presented discs of light is considered both as a function of the size of the discs and the retinal locus of their presentation. Ss were required to report whether a comparison disc was seen as larger or the same size as a standard disc when the two were presented briefly together. Results showed that the and required for 50% difference discrimination was independent of the size of the disc and was constant at about 30 sec of arc. For peripheral presentations, the jnd was found to increase in a linear manner with increasing eccentricity of presentation. Comparisons are drawn between the results obtained and peripheral visual acuity data and it is speculated that similar processes are involved in both situations.
