This article examines the order in which people recognize and respond to different levels of structure within a visual display. Certain previous experiments have been interpreted as showing that information about global characteristics of an array is extracted by the visual system before information about local characteristics. Results from a task in which the observer must attend to both global and local information demonstrate that local information has a large influence on reaction time even when information at the global level is sufficient to determine the response. This finding implies that local information becomes available to decision processes with a time course similar to that of global information. Effects previously attributed to the order in which different levels of structure are recognized may result from differential ease of directing attention to these different levels and selecting responses based on them.
本文研究了人们识别视觉展示中不同结构层次并做出反应的顺序。之前的某些实验被解释为表明视觉系统在提取关于阵列局部特征的信息之前，先提取了关于其全局特征的信息。在一项观察者必须同时关注全局和局部信息的任务中得到的结果表明，即使全局层面的信息足以确定反应，局部信息对反应时间仍有很大影响。这一发现意味着局部信息在与全局信息相似的时间进程内可供决策过程使用。先前归因于不同结构层次识别顺序的效应，可能是由于将注意力导向这些不同层次并基于它们选择反应的难易程度不同所致。
