Investigations of the processing of brief visual displays, and the explanation of such processing in terms of iconic memory, are reviewed. It is concluded that the concept of a pre-categorical sensory memory for visual material remains tenable. The ability to report material from brief visual displays is seen as depending upon parallel (and perhaps unlimited) transfer from iconic memory to a post-categorical memory mode, followed by a limited (and perhaps serial) transfer to an output stage. Decisions about, or responses to, items can only be made when they are in the output stage. Because transfer out of the post-categorical mode can be performed on the basis of pre-categorical stimulus features, pre-categorical information about items in the post-categorical mode must be accessible. One way in which this would be possible is if the transfer of an item into the post-categorical mode takes the form of the creation, to represent the item, of a temporary file of information including both pre-categorical and post-categorical features of the item. Any such feature can be used as the basis for selecting the item for transfer from the post-categorical mode to the output stage, for subsequent decision or report.
本文回顾了对简短视觉显示处理的研究,以及根据图像记忆对这种处理的解释。得出的结论是,视觉材料的前分类感觉记忆概念仍然成立。从简短视觉显示中报告材料的能力被视为取决于从图像记忆到后分类记忆模式的并行(可能是无限制的)转移,随后是到输出阶段的有限(可能是串行的)转移。只有当项目处于输出阶段时,才能对其做出决策或做出反应。由于可以基于前分类刺激特征执行从后分类模式的转移,因此必须能够访问后分类模式中项目的前分类信息。实现这一点的一种可能方式是,如果项目转移到后分类模式采取创建一个临时信息文件的形式,以代表该项目,该文件包括项目的前分类和后分类特征。任何此类特征都可以用作从后分类模式选择项目转移到输出阶段的基础,以便随后进行决策或报告。
