The integration between Gestalt grouping cues has been a relatively unexplored issue in vision science. The present work introduces an objective indirect method based on the repetition discrimination task to determine the rules that govern the dominance dynamics of the competition between both intrinsic (Experiment 1: proximity vs. luminance similarity) and extrinsic grouping cues (Experiment 2: common region vs. connectedness) by means of objective measures of grouping (reaction times and accuracy). Prior to the main task, a novel objective equating task was introduced with the aim of equating the grouping strength of the cues for the visuomotor system. The main task included two single conditions with the grouping cues acting alone as well as two competing conditions displaying the grouping factors pitted against one another. Conventional aggregated analyses were combined with individual analysis and both revealed a consistent pattern of processing dominance of: (1) luminance similarity over proximity, and of (2) common region over connectedness. Interestingly, the individual analyses showed that, despite the heterogeneous responses to the single conditions, the pattern of dominance between cues was robustly homogenous among the participants in the competing conditions.

格式塔分组线索之间的整合一直是视觉科学中一个相对未探索的问题。目前的工作引入了一种基于重复判别任务的客观间接方法，以确定控制内在（实验 1：接近度与亮度相似性）和外在分组线索（实验 2：公共区域与亮度相似性）之间竞争的优势动态的规则。 . 连通性）通过客观的分组测量（反应时间和准确性）。在主要任务之前，引入了一个新的客观等效任务，目的是使视觉运动系统的线索的分组强度相等。主要任务包括两个单一条件，分组线索单独起作用，以及两个竞争条件显示分组因素相互对抗。传统的聚合分析与个体分析相结合，两者都揭示了处理优势的一致模式：(1) 亮度相似性而非邻近性，以及 (2) 公共区域而非连通性。有趣的是，个体分析表明，尽管对单一条件的反应不同，但在竞争条件下的参与者之间，线索之间的优势模式是完全同质的。
