LONGITUDINAL STUDIES OF ADULT COGNITIVE DEVELOPMENT

西雅图纵向研究(SLS)调查了认知 成年人的发育超过28年将延长到 另一个七年的间隔，包括获得第六波 面板。核心项目支持面板和数据的维护 档案馆。这四个次级项目将研究扩展到新的方向； (1)一项家庭相似性研究将招募900名儿童和600名儿童 现任和前任SLS参与者的兄弟姐妹进行调查 能力状态在几代人之间的代际变化，并检查 认知能力中的亲子关系和兄弟姐妹关系，而不是 在成年人身上进行了检查。(2)健康史研究涉及 二次数据分析：(A)疾病、 智力的稳定和衰退，以及(B)两者之间的关系 老年人疾病的发生与认知训练的有效性 对智力衰退的补救。将更新健康历史记录 1983-85年度评估的所有科目以及 将在拟议的1990-92年度周期内评估的纵向课题。(3) 认知功能长期影响的七年随访研究 培训和实践将调查这些干预措施如何影响 认知老化的水平和速度。大约300名参与者 将接受5个小时的归纳推理认知培训或 空间定位以及5小时的前测/后测电池。 将用大约200个配对对照来评估练习效果 参与者。队列效应在认知训练中的有效性 简要的助推器培训程序和将培训转移到REAL 生活任务也将被审查。(4)纵向第六波 对认知功能的研究将有助于进一步研究 人口统计学变化对成人认知发展的影响 婴儿潮前和婴儿潮时期的人群。在这项研究中，大约有1000人 纵向受试者将被重新测试，一个由650名受试者组成的新小组 将在5小时的心理测试中进行初步评估。这 研究将产生适用于七年评估的数据 青壮年能力因素结构的纵向变化 度过了晚年。

The Seattle Longitudinal Study (SLS) which has investigated cognitive development in adults over a 28 year period is to be extended over another seven-year interval including the acquisition of a sixth wave panel. The core project supports the maintenance of panels and data archives. The four subprojects extend the study into new directions; (1) A family resemblance study will recruit 900 children and 600 siblings of current and former SLS participants, to investigate generational shifts in ability status across generations, and to examine parent-offspring and sibling correlations in cognitive abilities, not heitherto examined in adults. (2) A health history study involves secondary data analyses of the relationship between (a) disease, intellectual stability and decline, and (b) of the relationship between the occurrence of disease and effectiveness of cognitive training in the remediation of intellectual decline. Health histories will be updated for all subjects assessed in the 1983-85 cycle, as well as for the longitudinal subjects to be assessed in the proposed 1990-92 cycle. (3) A seven-year follow-up study on the long-term effects of cognitive training and practice will investigate how such interventions affect both level and rate of cognitive aging. Approximately 300 participants will receive 5 hours of cognitive training on Inductive Reasoning or Spatial Orientation as well as a 5 hour pretest/ posttest battery. Practice effects will be assessed with approximately 200 matched control participants. Cohort effects in cognitive training, the effectiveness of brief booster training procedures and transfer of training to real life tasks will also be examined. (4) A sixth wave of the longitudinal study of cognitive functioning will permit further investigation of the impact of demographic changes upon adult cognitive development in the pre-babyboom and babyboom cohorts. In this study approximately 1000 longitudinal subjects will be retested, and a new panel of 650 subjects will be initially assessed on a 5 hour psychometric test battery. This study will generate data suitable for the seven-year assessment of longitudinal changes in ability factor structure from young adulthood through advanced old age.
