COGNITIVE AGING IN CONTEXT: ABILITIES, LITERACIES, AND THE SOCIAL ENVIRONMENT

本研究拟采用威斯康星州纵向研究（WLS）对大学生在学习过程中的几个方面进行研究。 研究参与者不断变化的认知功能和不断变化的环境之间的相互作用 孩子们当中.我们建议首先对测量结构进行广泛的评估， WLS认知数据的属性，我们将使用WLS和健康之间的重叠措施 和退休研究（MRS），以描述WLS中的认知功能范围与 来自同一队列和其他感兴趣人群的全国代表性分布。那就 使用相互因果关系模型来估计工作中的社会和智力活动如何， 休闲影响认知功能，并受认知功能影响。我们将研究认知差异是如何在 参与者对最近政策关注的两个与健康有关的决策背景的反应涉及： 他们希望参与有关他们的医疗决定的过程，以及他们的 关于新的和复杂的医疗保险处方药福利的行为。我们还将研究如何 认知功能与受访者使用和受益于互联网的程度和程度有关， 特别是在寻求与他们的健康相关的信息时。最后，我们将探讨和评估 认知功能、社会环境和决策过程 对整个样本和主要亚群中的APOE进行评估，例如由以下定义的亚群： 性别、早期认知能力、教育程度、经济和家庭角色。

This research proposes to use the Wisconsin Longitudinal Study (WLS) to study several aspects of the interplay between the changing cognitive functioning of study participants and the changing circumstances of their lives. We propose first to provide an extensive assessment of the measurement structure and properties of the WLS cognitive data, and we will use overlapping measures between the WLS and Health and Retirement Study (MRS)to depict how the range of cognitive function in the WLS compares to a nationally representative distribution from the same cohort and other populations of interest. Then, we will use models of reciprocal causation to estimate how social and intellectual engagements at work and in leisure affect and are affected by cognitive functioning. We will study how cognitive variation among participants is implicated in their response to two health-related decision contexts of recent policy concern: their desired involvement in the process of making decisions about their medical treatment, and their behavior regarding the new and complicated Medicare prescription drug benefit. We will examine also how cognitive functioning is related to how much and how well respondents use and benefit from the Internet, especially in seeking information relevant for their health. Finally, we will explore and assess variations in cognitive functioning, social environments, and decision-making processes across the life course in relation to an assessment of APOE in the entire sample and in major subpopulations, such as those defined by gender, early cognitive ability, educational attainment, and economic and family roles.
