搜索高度可分辨的特征的连词可以是快速的，甚至是并行的。本文基于(A)知觉分离、(B)连接检测器和(C)由两个或多个分心功能单独控制的抑制，探讨了三种可能的解释。颜色、大小、方向和运动方向的连词搜索率与知觉分离的独立衡量标准密切相关。然而，它们似乎与单一单位反应的生理学无关。每个维度对关联搜索率都有额外的贡献，这表明每个维度都是独立于其他维度进行检查的。未知目标似乎只能通过依次对每个目标进行连续搜索才能找到。搜索4组分心物比搜索2组慢。研究结果表明，这是对特征整合理论的一种修改，在特征整合理论中，注意力不仅由单一的“窗口”控制，还由一种基于特征的抑制形式控制。
Search for conjunctions of highly discriminable features can be rapid or even parallel. This article explores three possible accounts based on (a) perceptual segregation,(b) conjunction detectors, and (c) inhibition controlled separately by two or more distractor features. Search rates for conjunctions of color, size, orientation, and direction of motion correlated closely with an independent measure of perceptual segregation. However, they appeared unrelated to the physiology of single-unit responses. Each dimension contributed additively to conjunction search rates, suggesting that each was checked independently of the others. Unknown targets appear to be found only by serial search for each in turn. Searching through 4 sets of distractors was slower than searching through 2. The results suggest a modification of feature integration theory, in which attention is controlled not only by a unitary" window" but also by a form of feature-based inhibition.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
