除了精细空间敏锐度之外， 视觉能力的存在，人们可以期望， 可靠的不同。 其中一种能力， 注意力不足是暂时的敏锐度， 解决随时间推移而呈现的刺激。 结果 第一阶段小企业创新研究（SBIR）研究建立 新的人的绩效衡量的技术基础 以测量视觉效果为目的的产品 一系列测试的时间敏锐度 研究 第二阶段研究的目标是收集数据， 有必要把实验室演示的时间 将视觉中的现象提升到实验室之外的水平， 将时间敏锐度测量从当前组移动到 新的和更快的计算机硬件;开发和测试新的 候选措施的时间视力;发展的 综合表现任务（一项任务， 组件，需要警惕和快速反应，以良好的视觉 细节嵌入在一个大的和可变的视野）;收集 与时间敏锐度成套测验（TAB）测量相关的数据， 在综合任务上的表现;发展可靠性与 时间权衡功能和制定实践准则 直到稳定性和长期可靠性;收集数据， 其它实验室空间和时间视觉测试（例如，静态 和动态对比敏感度），以用作 进行研究，评估酒精和 老化的时间敏锐度;汇集从所有收集的数据 进行电池因素分析的研究;以及 建立原型电池。 该项目旨在生产 一个评估系统，为考试管理员提供 对实地研究进行有用的数据解释和预测， 在工作场所。 这样的系统可以帮助我们 了解如何提高时间视力 在某种程度上，这种能力是必要的， 工作、任务、休闲活动以及如何确定时间 视觉显示方面，以促进理解， 工程设计

Over and above fine-spatial acuity, a substantial number of visual capabilities exist on which persons can be expected to differ reliably. One such capability which has received insufficient attention is temporal acuity, the capability to resolve stimuli which are presented over time. Results of the Phase I Small Business Innovation Research (SBIR) study establish the technical basis for a new human performance measurement product that has as its purpose the measurement of visual temporal acuity with a battery of tests. The research objectives of the Phase II study focus on collecting data necessary to bring laboratory demonstrations of temporal phenomena in vision to a level useful outside the laboratory by moving the temporal acuity measures from the present battery to the new and faster computer hardware; developing and testing new candidate measures of temporal visual acuity; developing the synthetic performance task (a task with substantial visual components, requiring vigilance and quick response to fine visual detail embedded in a large and variable visual field); collecting data relating Temporal Acuity Battery (TAB) measures to performance on the synthetic task; developing reliability vs. time trade-off functions and establishing guidelines for practice until stability and long-term reliability; collecting data from other laboratory spatial and temporal visual tests (e.g., static and dynamic contrast sensitivity) to serve as correlates of the TAB; conducting studies assessing the effects of alcohol and aging on temporal acuity; pooling the data collected from all studies to perform Factor Analysis of the battery; and establishing the prototype battery. The project aims to produce an assessment system that provides test administrators with useful data interpretations and prediction on field studies and in the workplace. Such a system can contribute to our understanding of how to improve temporal visual acuity performance to the extent that such abilities are required for jobs, tasks, leisure activities and how to identify temporal aspects of visual displays so as to advance understanding in engineering design.
