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.

拟议研究的目的是进行为期七年的跟踪调查。 测试具有广泛的智力和认知能力 对150名年龄在58岁至73岁之间的老年人进行测试 他们最初在1980年至1981年进行测试时的年龄。数据将是 收集与图形知觉速度因素相关的变量， 象征性知觉速度、言语理解、归纳推理 选择反应时间和Sternberg反应时间。所获得的数据将 用于检验关于因素结构中年龄变化的假设，均值 因素水平，并评估与性别、主观健康的关系 和受教育程度。 继续研究被计划为逻辑扩展和部分 复制在前一个供资期间进行的研究。 在拟议研究的第一年，最终数据分析和报告 之前这项研究的写作将被完成。还有，文件 将完成组织和测试监督员培训。在第一次 本年度，将开始招聘、安排和复试。测试、评分 计算机文件录入将持续16个月。数据减少， 分析和报告撰写工作将在过去九个月内完成 在授权期内。 这项研究的总体目的是加深对 老年人能力因素结构和平均因素水平的年龄变化 也是为了更好地了解这种变化的前因。
