本研究探讨了注意力资源是否可以同时分配到几个位置的视觉显示，处理模式（串行或并行）是否可以在一个审判中切换，以及注意力资源集中在一个无效的位置时的成本的性质。受试者被要求确定两个目标字母中的哪一个出现在八个字母的圆形显示器中。在precue条件下，一个主要的和次要的目标位置被指定为目标发病前150毫秒的指标，有效性不同。在对照条件下，没有提供线索。第二个实验验证了在解释实验1的数据时所做的几个假设。Jonides（1983）的双加工模型的修正建议在注意资源的变焦透镜模型。代替两种可选的处理模式，注意力资源被认为能够分布在整个视野中，但具有低分辨率，或者连续地收缩到视野的小部分，伴随着处理能力的增加。
This research investigated whether attentional resources can be simultaneously allocated to several locations in a visual display, whether the mode of processing (serial or parallel) can be switched within a trial, and the nature of the costs when attentional resources are concentrated on an invalid location. Subjects were required to determine which of two target letters was present in eight-letter circular displays. In precue conditions, a primary and a secondary target location were designated 150 ms before target onset by an indicator that varied in validity. In the control conditions no cue was provided. A second experiment verified several assumptions that had been made in interpreting the data of Experiment 1. Modifications in Jonides' (1983) two-process model were suggested in terms of a zoom lens model of attentional resources. Instead of two alternative processing modes, attentional resources are conceived as capable of distribution over the visual field, but with low resolving power, or as continuously constricting to small portions of the visual field with a concomitant increase in processing power.
