AGING INFLUENCES ON SUSTAINED ATTENTION AND TASK-UNRELATED IMAGES AND THOUGHTS

这项工作试图确定持续注意力的性质， 确定任务无关图像和想法（TUITS）的参数， 以及相关的心理活动，如洞察力，注意力和持续的 注意力作为现象，它们之间的关系，以及它们之间的关系。 成年后易受衰老的影响。 这些目标是 通过使用受控实验室研究完成， 回顾性问卷调查。 今年的调查结果是（a）扩大了 警戒任务的实践，具有典型的暴露时间，最适合于 双曲函数关系式， 年龄显著影响最终渐近性能的学习 但不影响学习率;（B）TUIT似然性与学习率成反比 与警戒任务的性能相关，反映了能力需求 警戒任务。 对成人中与任务无关的图像和思想的研究，沿着 变量，可以缓和其发生，例如，年龄、智力、任务 结构等，可以帮助我们理解 这是所有思考的基础。 持续的注意力作为一种技能， 长时间保持警觉和专注。 这个技能扮演一个 在日常生活和就业市场中的重要作用，例如，工作 需要检查。 他的研究为我们提供了 影响了技能的使用和获得， 和浓度易受老化影响。

This work attempts to determine the nature of sustained attention and to deter-mine the parameters of task-unrelated images and thoughts (TUITS) as well as related mental activity such as insight, attention and sustained attention as phenomena, their relationships amongst one another, and their susceptibility to the influence of aging in adulthood. These goals are accomplished through the use of controlled laboratory studies and retrospective questionnaires. This year's findings were that (a) extended practice on a vigilance task, with typical exposure times, is best fit by a hyperbolic functional relationship derived from an accumulation model of learning in which age significantly affects final asymptotic performance but which does not affect learning rate; (b) TUIT likelihood is inversely related to performance on a vigilance task an reflects the capacity demands of the vigilance task. The study of task-unrelated images and thoughts in adults, along with variable which may moderate their occurrence, e.g., age, intelligence, task structure, etc., may aid us in understanding the fundamental processes which underlie all thinking. Sustained attention as a skill involves both alertness and concentration over long periods of time. This skill plays an important role in both daily living and in the job market place, e.g., jobs requiring inspection. his research provides us with information on how age influences the use and acquisition of that skill as well as how alertness and concentration are susceptible to aging influences.
