通过在单个干扰流（实验 1）或不同流（实验 2-6）中简要呈现单词，使用 53 毫秒/项目的快速串行视觉呈现来调查 2 个书面单词之间的注意力竞争。刺激开始异步 (SOA) 从 0 到 213 毫秒变化。所有 SOA 都存在激烈的竞争，但哪个词更有可能被报道却在 SOA 中发生了显着变化。在 13-53 毫秒范围内的 SOA 中，第二个单词更有可能被报告，但在 213 毫秒时，优势转向第一个单词，如注意力眨眼中那样。提出了一种 2 阶段注意力竞争模型，其中对检测到的目标的注意力在第 1 阶段不稳定。当识别出一个目标时，第 1 阶段结束，启动巩固该目标的串行第 2 阶段过程。
Competition for attention between 2 written words was investigated by presenting the words briefly in a single stream of distractors (Experiment 1) or in different streams (Experiment 2-6), using rapid serial visual presentation at 53 ms/item. Stimulus onset asynchrony (SOA) was varied from 0 to 213 ms. At all SOAs there was strong competition, but which word was more likely to be reported shifted markedly with SOA. At SOAs in the range of 13-53 ms the second word was more likely to be reported, but at 213 ms, the advantage switched to the first word, as in the attentional blink. A 2-stage competition model of attention is proposed in which attention to a detected target is labile in Stage 1. Stage 1 ends when one target is identified, initiating a serial Stage 2 process of consolidation of that target.
