本研究探讨了模式规则性在近似数值处理中的作用。实验1表明，刺激大小的变化对随机和规则模式的适应后效有明显的影响。对于常规模式，适应大模式并用小模式进行测试比反向处理产生更强的后效，在反向处理中，参与者适应小模式并用大模式进行测试。对于随机模式，不存在这种效应。实验2揭示了一个显着的连接性效应的随机和规则模式的数字化处理。对于随机模式，参考刺激被认为包含较少的项目时，点连接的线比当他们没有连接，和项目的数量在连接的参考被进一步低估时，参与者适应不连接的模式与相同数量的点。对于常规模式，这种效应是不存在的。因此，不同的机制建议的随机和规则模式的数量编码。对于随机模式，主要纹理特征的变化将从数量处理中提取出来，而连通性可以通过影响数字单位个性化的处理来影响这种编码。对于规则的图案，通用的数值处理被抑制，数值判断似乎是从纹理特征的视觉处理结果，如点的大小或相邻点之间的距离推断。
This study investigated the role of pattern regularity in approximate numerical processing. Experiment 1 demonstrated that the change in stimulus size has a distinct effect on the adaptation aftereffect for random and regular patterns. For regular patterns, adapting to large patterns and being tested with small patterns caused stronger aftereffects than the reverse treatment, in which the participants adapted to small patterns and were tested with large patterns. For random patterns, this effect was absent. Experiment 2 revealed a distinct connectedness effect on the numerosity processing of random and regular patterns. For random patterns, reference stimuli were perceived to contain fewer items when the dots were connected by lines than when they were not connected, and the number of items in the connected reference was further underestimated when the participants adapted to unconnected patterns with the same number of dots. For regular patterns, this effect was absent. Distinct mechanisms were thus suggested for the numerosity coding of random and regular patterns. For random patterns, the change in primary texture features would be abstracted from numerosity processing, while connectedness could affect this coding by affecting the processing of numerical unit individuation. For regular patterns, generic numerosity processing is inhibited, and numerical judgments appear to be inferred from the visual processing results of texture features such as dot size or the distance between adjacent dots.
