A computational theory of visual attention is presented. The basic theory (TVA) combines the biased-choice model for single-stimulus recognition with the fixed-capacity independent race model (FIRM) for selection from multi-element displays. TVA organizes a large body of experimental findings on performance in visual recognition and attention tasks. A recent development (CTVA) combines TVA with a theory of perceptual grouping by proximity. CTVA explains effects of perceptual grouping and spatial distance between items in multi-element displays. A new account of spatial focusing is proposed in this paper. The account provides a framework for understanding visual search as an interplay between serial and parallel processes.
提出了一种视觉注意的计算理论。基本理论(TVA)将单刺激识别的偏向选择模型与用于从多元素显示中进行选择的固定容量独立竞争模型(FIRM)相结合。TVA整理了大量关于视觉识别和注意任务表现的实验结果。最近的一项进展(CTVA)将TVA与基于接近度的知觉分组理论相结合。CTVA解释了多元素显示中知觉分组和项目间空间距离的影响。本文提出了一种关于空间聚焦的新解释。该解释为理解视觉搜索作为串行和并行过程之间的相互作用提供了一个框架。
