OBJECTIVE We examined the influence of a broad spectrum of life experiences on longitudinal cognitive trajectories in a demographically diverse sample of older adults. METHOD Participants were 333 educationally, ethnically, and cognitively diverse older adults enrolled in a longitudinal aging study. Mixed-effects regression was used to measure baseline(More)
OBJECTIVES Poor quality of early life conditions has been associated with poorer late life cognition and increased risk of dementia. Early life physical development can be captured using adult measures of height and head circumference. Availability of resources may be reflected by socioeconomic indicators, such as parental education and family size. We(More)
Background/Objectives: Physical function indicators, including gait velocity, stride time and step length, are linked to neural and cognitive function, morbidity and mortality. Whereas cross-sectional associations are well documented, far less is known about long-term patterns of cognitive change as related to objective indicators of mobility-related(More)
OBJECTIVE The objective was to determine whether neuropsychological tests provide an equivalent measure of the same psychological constructs in older adults with low versus higher levels of education. METHOD Confirmatory factor analysis was used to evaluate the fit of a three-factor model (Verbal Ability, Visuospatial Ability, Long-Term Retention) to(More)
BACKGROUND We evaluated the utility of the telephone-administered Mental Alternation Test (MAT, an oral variant of the Trail-Making Test) for remote assessment of cognitive functioning in older adults. We examined (1) the sensitivity of MAT scores to cognitive change across 4 age groups, (2) practice effects associated with repeat administration, and (3)(More)
Administration mode, age, education, and practice effects were examined for the Mental Alternation Test (MAT), a brief orally administered measure of executive function. Participants (N = 135) between the ages of 65 and 85 years completed the MAT twice in person, twice over the telephone, or once in person and once over the telephone. MAT scores did not(More)
