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

这项工作试图确定与任务无关的参数 图像和思想(TUITs、白日梦/走神)以及 相关的心理活动，如洞察力、注意力和持续性 注意力作为现象，它们之间的关系， 以及他们成年后对衰老的影响的敏感性。 这些目标是通过使用受控的 实验室研究和回溯性问卷。今年的 研究结果是：(A)阅读过程中的Tuit频率与之相反 与主题对材料的兴趣有关：(B)吹奏频率 显示了昼夜节律变化，最小值约为午夜和 在上午10时左右达到最大值，(C)在7年内纵向下降 通过回溯性问卷测量白日梦的频率， 以及(D)在高警戒事件任务方面的扩展实践， 典型的暴露时间，不会减少或消除年龄减退 在表演上。

This work attempts to determine the parameters of task-unrelated images and thoughts (TUITs, daydreaming/mindwanding) 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: (a) TUIT frequency during reading is inversely related to subject interest in the material, (b) TUIT frequency shows a circadian variation with a minimum about midnight and a maximum at about 10 am, (c) longitudinal decreases over 7 years in daydreaming frequency as measured by retrospective questionnaire, and (d) extended practice on a high event vigilance task, with typical exposure times, does not reduce or eliminate age decrements in performance.
