A pattern of differential reaction time (RT) benefits obtained in spatial-precuing tasks has been attributed to translation processes that operate on mental codes formed to represent the stimulus and response sets. According to the salient-features coding principle, the codes are based on the salient stimulus and response features, with RTs being fastest when the two sets of features correspond. Three experiments are reported in which the stimulus and response sets were manipulated using Gestalt grouping principles. In the first two experiments, stimuli and responses were grouped according to spatial proximity, whereas in the last experiment, they were grouped according to similarity. With both types of manipulations, the grouping of the stimulus set systematically affected the pattern of precuing benefits. Thus, in these experiments, the organization of the stimulus set was the primary determinant of the features selected for coding the stimulus and response sets in the translation process.
在空间线索任务中获得的差异反应时（RT）优势模式，被归因于对为表征刺激和反应集而形成的心理代码进行操作的转换过程。根据显著特征编码原则，这些代码基于显著的刺激和反应特征，当两组特征对应时，反应时最快。本文报告了三个实验，其中使用格式塔分组原则对刺激和反应集进行了操纵。在前两个实验中，刺激和反应根据空间接近度进行分组，而在最后一个实验中，它们根据相似性进行分组。通过这两种类型的操纵，刺激集的分组系统地影响了线索提示优势的模式。因此，在这些实验中，刺激集的组织是在转换过程中为编码刺激和反应集而选择的特征的主要决定因素。
