提出了一种视觉注意的计算理论。基本理论（TVA）结合了偏置选择模型的单刺激识别与固定容量的独立种族模型（FIRM）的选择，从多元素显示。TVA组织了大量的视觉识别和注意力任务的实验结果。最近的发展（CTVA）结合TVA与感知分组的理论接近。CTVA解释了感知分组和多元素显示中项目之间的空间距离的影响。本文提出了一种新的空间聚焦解释。该帐户提供了一个框架，理解视觉搜索之间的相互作用，串行和并行的过程。
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.
