Abstract

A replication of Cohen (1973) was conducted in an attempt to substantiate the claim for serial processing in the left hemisphere and parallel processing in the right hemisphere for visual information. Subjects made same or different judgments to hemispherically projected visual arrays of two, three, or four letters and reaction times were measured. No support for a serial vs. parallel hemispheric processing distinction was obtained, but strong support for overall left hemisphere superiority for visual search was found with both the reaction time and error percentage data. The implications for an information processing strategy for this task as well as various methodological considerations are discussed.

摘要

为了证实关于左半球对视觉信息进行串行处理以及右半球对视觉信息进行并行处理的说法，进行了一项对科恩（1973年）研究的复制实验。受试者对半球投射的由两个、三个或四个字母组成的视觉阵列做出相同或不同的判断，并测量反应时间。未获得对半球串行与并行处理差异的支持，但在反应时间和错误百分比数据方面都发现了对视觉搜索中左半球总体优势的有力支持。讨论了该任务信息处理策略的影响以及各种方法学上的考虑因素。
