Can observers access two spatially separated color targets (e.g., red and green) at the same time (i.e., in parallel)? According to the Boolean map theory of visual attention (Huang & Pashler, Psychological Review, 114(3), 599-631, 2007), access to two different features that belong to the same dimension (e.g., red and green targets) is limited and therefore can be held only in a serial fashion. The current study proposes a strong test of the Boolean map theory of attention through the application of two of the most rigorous stochastic approaches to response times modeling-the system factorial technology (Townsend & Nozawa, 1995) and the logical rule models (Fifić, Little, & Nosofsky, Psychological Review, 117, 309-348, 2010). These approaches allowed identification of serial, parallel, and coactive architectures in the processing of multicolor targets. The results showed that multiple-color targets are processed serially when observers are required to process all the targets in the display (i.e., an exhaustive stopping rule), and in parallel or coactively when observers can terminate the search when one of the targets is found (i.e., self-terminating stopping rule). These results are generally inconsistent with predictions of the Boolean map theory. They highlight the role of stopping rules in multicolor visual search, as well as the flexibility of the attentional system in shifting between processing architectures.
观察者能否同时（即并行地）获取两个空间上分离的颜色目标（例如红色和绿色）？根据视觉注意的布尔地图理论（Huang和Pashler，《心理评论》，第114卷第3期，599 - 631页，2007年），获取属于同一维度的两个不同特征（例如红色和绿色目标）是受限的，因此只能以串行方式进行。当前研究通过应用两种最严格的反应时间建模随机方法——系统因子技术（Townsend和Nozawa，1995年）和逻辑规则模型（Fifić、Little和Nosofsky，《心理评论》，第117卷，309 - 348页，2010年），对注意的布尔地图理论进行了有力检验。这些方法能够识别多颜色目标处理过程中的串行、并行和协同激活架构。结果表明，当要求观察者处理显示中的所有目标时（即穷尽停止规则），多颜色目标是串行处理的；而当观察者在找到其中一个目标时就可以终止搜索时（即自终止停止规则），则是并行或协同激活处理。这些结果总体上与布尔地图理论的预测不一致。它们突出了停止规则在多颜色视觉搜索中的作用，以及注意系统在处理架构之间转换时的灵活性。
