We very much welcome and will support new investigator-led projects. For active and planned projects below, please contact the lead investigators, Scott Hofer or Andrea Piccinin, if you are interested in participating on a particular project. The lead investigator will maintain updates to each project, including the addition of coauthors based on the confirmation of collaborating studies. SP1-SP3 refer to specific subprojects of the current NIH P01 grant (AG043362). Please contact Scott Hofer (firstname.lastname@example.org) or Andrea Piccinin (email@example.com) if you would like to propose a new project.
Projects are generally organized into one of three subprojects:
SubProject 1: Health Conditions, Biomarkers, and Cognitive Aging (PL: Piccinin, Muniz)
This subproject examines changes in cognitive function in the context of health, including health status (i.e., morbidity, comorbidity) and changes in health. We investigate the effects of health on cognition, at the individual (i.e., within-person) level and in terms of the heterogeneity of diseases and other factors affecting aggregate change in populations differing in nation and birth cohort, by means of coordinated analyses of multiple longitudinal studies of aging.
SubProject 2: Personality and Well-Being Trajectories, Health, and Mortality (PL: Mroczek)
This is the largest-scale effort to date to perform Integrated Data Analysis (IDA) on longitudinal personality data. This project evaluates general patterns of population average and individual variation in change across distinct personality and well-being constructs. We also investigate the influence of personality on physical health, well-being, and longevity. A key focus is elucidation of mechanisms that explain the personality-health-longevity association, particularly health behaviors but also physiological mechanisms.
SubProject 3: Social Determinants of Change in Cognitive and Physical Functioning (PL: Hofer, Clouston)
This subproject takes advantage of opportunities for comparison of longitudinal studies in an international context to clarify the role of historical social and demographic trends on aging-related differences and changes in cognitive and physical function. We evaluate the role of social change across successive birth cohorts and the impact of work-related demands, age of retirement, and social class on change in cognitive and physical functioning.
