在2个实验中研究了注意力资源是否可以同时分配到视觉显示中的几个位置，处理模式（串行或并行）是否可以在一次试验中切换，以及注意力资源集中在无效位置时的成本性质。在每个实验中，6名大学生被要求确定2个目标字母中的哪一个出现在8个字母的圆形显示中。在precue条件下，一个主要和次要的目标位置被指定为目标发病前150毫秒的有效性不同的指标。在对照条件下，没有提供线索。实验II验证了在解释实验I的数据时所做的几个假设。在J. Jonides的（见记录1984-08558-001）2-过程模型的修改建议在注意资源的变焦透镜模型。注意力资源被视为能够分布在整个视野中，但分辨率较低，或者连续收缩到视野的小部分，伴随着处理能力的增加，而不是2种替代处理模式。(38参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Investigated in 2 experiments 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 resouces are concentrated on an invalid location. In each of the experiments, 6 college students were required to determine which of 2 target letters was present in 8-letter circular displays. In precue conditions, a primary and a secondary target location were designated 150 msec before target onset by an indicator that varied in validity. In the control conditions no cue was provided. Exp II verified several assumptions that had been made in interpreting the data of Exp I. Modifications in J. Jonides's (see record 1984-08558-001) 2-process model are suggested in terms of a zoom lens model of attentional resources. Instead of 2 alternative processing modes, attentional resources are seen 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.(38 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
