When stimuli are presented rapidly, repetitions are often undetected--a phenomenon called "repetition blindness" (RB; Kanwisher Cognition, 27, 117-143, 1987). Grouping of nonlinguistic items has been found to prevent RB (Goldfarb & Treisman Psychonomic Bulletin & Review, 18, 1042-1049, 2011). In order to determine whether this effect could be found with letters and words, participants viewed rapid serial visual presentation and brief simultaneous visual presentation streams containing groups of linguistic stimuli and provided judgments of frequency. The collection of reaction times and an explicit question about strategy use allowed for analyses of the participants' processing strategies. Two groups of participants emerged: one that demonstrated RB for groups of stimuli, and another that demonstrated enhanced perception with stimulus grouping. These participant groups did not appear to differ on the basis of explicit processing strategies or reaction times.
当刺激快速呈现时，重复往往未被察觉——这一现象被称为“重复盲视”（RB；Kanwisher，《认知》，第27卷，第117 - 143页，1987年）。已发现非语言项目的分组可防止重复盲视（Goldfarb和Treisman，《心理物理学通报与评论》，第18卷，第1042 - 1049页，2011年）。为了确定这种效应是否也能在字母和单词中发现，参与者观看了包含语言刺激组的快速序列视觉呈现和短暂同时视觉呈现流，并对频率进行判断。收集反应时间以及一个关于策略使用的明确问题，以便分析参与者的加工策略。出现了两组参与者：一组对刺激组表现出重复盲视，另一组对刺激分组表现出增强的感知。这些参与者组在明确的加工策略或反应时间方面似乎没有差异。
