AGE CHANGES IN INTELLECTUAL ABILITIES IN THE ELDERLY

拟议研究的目的是进行为期七年的跟踪调查。 通过一系列智力和认知能力测试， 对150名年龄在58至73岁之间的老年人进行了测试 1980年至1981年首次测试时的年龄。 数据将 收集与图形感知速度因素相关的变量， 符号感知速度、言语理解、归纳推理、 选择反应时和斯滕贝格反应时。 获得的数据将 用于检验有关因素结构中年龄变化的假设， 因素水平，并评估与性别，主观健康 和教育状况。 继续研究计划作为逻辑延伸和部分 重复上一个供资期进行的研究。 在拟议研究的第一年，最终数据分析和报告 之前的研究报告都要完成。 另外，file 组织和测试普罗克特培训将完成。 在第一 2009年，将开始招募、安排和重新测试。 测试、评分 而电脑档案输入将持续十六个月。 数据简化， 分析和报告编写将在最后9个月内完成 的补助期。 研究的总体目的是加深对以下方面的了解： 老年人能力因素结构和平均因素水平的年龄变化 人，并更好地了解这种变化的先行者。

The purpose of the proposed study is to carry out a seven year follow-up testing with an extensive battery of intellectual and cognitive abilities tests on a sample of 150 elderly persons ranging in age from 58 to 73 years of age when they were originally tested in 1980 to 1981. Data will be gathered on variables related to factors of Figural Perceptual Speed, Symbolic Perceptual Speed, Verbal Comprehension, Inductive Reasoning, Choice Reaction Time and Sternberg Reaction Time. The obtained data will be used to test hypotheses concerning age changes in factor structure, mean factor levels, and to evaluate relationships with sex, subjective health and educational status. The continuation study is planned as a logical extension and partial replication of the study carried out in the previous funding period. During the first year of the proposed study, final data analyses and report writing from this previous study are to be completed. Also, file organization and test proctor training will be completed. During the first year, recruitment, scheduling and retesting will begin. Testing, scoring and computer file entry will continue for sixteen months. Data reduction, analyses and report writing will be completed during the last nine months of the grant period. The overall purpose of the study is to achieve an enhanced understanding of age changes in ability factor structure and mean factor levels in elderly persons, and also to better understand antecedants of such change.
