ATTENTIONAL PROCESSES IN NORMAL AND IMPAIRED ELDERLY

我们试图了解的心理和生物心理方面的 注意力和注意力的正常和病理老化 流程.我们还关心如何运用这些知识来发展 改善注意力和认知功能的策略。今年 我们报告的调查，补偿变化的持续 注意情况，导致不成比例的改善， 老年人的表现。一个特别强大的变化是 增加刺激的暴露时间-老年人改善了他们的 而年轻人和中年人则不受 增加曝光时间。我们还开始开发一种 注意力转换功能测试，将用于我们的尝试， 提供阿尔茨海默病的早期标志物。

We seek to understand the psychological and biopsychological aspects of normal and pathological aging in terms of attention and attentional processes. We are also concerned with applying that knowledge to develop strategies for improving attentional and cognitive functioning. This year we report on an investigation into compensatory variations in sustained attention situations which result in disproportional improvements in performance in the elderly. A particularly powerful variation was the increase in exposure time of the stimuli-the elderly improved their performance while the young and middle-aged were unaffected by the increase in exposure time. We have also begun the development of an attention-switching functional test which will be used in our attempts to provide early markers of Alzheimer's Disease.
