项目摘要

In the first year, research efforts were directed to the selection of an appropriate task. The results suggested that reaction times might not be a good choice, since it might be contaminated by the processes that were not related to the mechanisms and workings of spatial attention (i.e., direct facilitation or priming of response initiation and programming). Therefore, a perceptual task seemed to be a better choice. A survey of the Literature suggested that the multiple-item sequential presentation method developed by Weiselgartner and Sperling (1987) would satisfy the requirements. The methodpresented multiple items successively at the same location in short time interval. The method was considered to be suitable for the purpose of the present research, because it could avoid automatic attention capturing, allowing only for the working of controlled attention processes and did not depend on reactiontime measures.In the second year, the hypothesis that the gap effect would facilitate not only saccadic latency but also that of attention shifts was tested with this method. The results of two experiments, one with naive subjects and the other with two trained subjects, could not confirm the hypothesis. However, since Mackeben and Nakayama (1993) recently reported the gap effects for spatial attention shifts using a vernier acuity task, it was felt that the clarification of this contradiction would help reveal the mechanisms with which spatial attention facilitates our visual functions.

在第一年，研究工作是针对选择适当任务的。结果表明，反应时间可能不是一个不错的选择，因为它可能被与空间注意力的机制和起作用无关的过程污染（即直接促进或响应启动和编程的启动）。因此，感知任务似乎是一个更好的选择。对文献的调查表明，Weiselgartner和Sperling（1987）开发的多项序列呈现方法将满足要求。该方法在短时间间隔在同一位置依次将多个项目延长。该方法被认为适合本研究的目的，因为它可以避免自动关注捕获，仅允许进行受控注意力的过程而不依赖于反应时间措施。第二年，差距效应不仅促进了Saccadic延迟，而且通过这种方法测试了注意力转移。两个实验的结果，一个具有幼稚的受试者，另一个具有两个受过训练的受试者的结果，无法证实该假设。然而，由于Mackeben和Nakayama（1993）最近报道了使用Vernier Acuity任务的空间注意力转移的差距效应，因此人们认为对这种矛盾的澄清将有助于揭示空间注意力促进我们的视觉功能的机制。
