On average, older people remember less and walk more slowly than do younger persons. Some researchers argue that this is due in part to a common biologic process underlying age-related declines in both physical and cognitive functioning. Only recently have longitudinal data become available for analyzing this claim. We conducted a systematic review of(More)
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)
This case study describes the process of fusing the data from several wind tunnel experiments into a single coherent visualization. Each experiment was conducted independently and was designed to explore different flow features around airplane landing gear. In the past, it would have been very difficult to correlate results from the different experiments.(More)
OBJECTIVE Numerous studies show that depressive symptoms measured at a single assessment predict greater future stroke risk. Longer-term symptom patterns, such as variability across repeated measures or worst symptom level, might better reflect adverse aspects of depression than a single measurement. This prospective study compared five approaches to(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)
OBJECTIVE To determine whether neuropsychological tests and the Hachinski Ischemic Score (HIS) can differentiate incident vascular dementia (VaD) from Alzheimer's disease (AD) in nondemented older adults within 5 years of initial testing. METHODS The Canadian Study of Health and Aging (CSHA) included three waves: CSHA-1 (1991-1992), CSHA-2 (1996-1997),(More)
Previous research has demonstrated sex differences in face processing at both neural and behavioural levels. The present study examined the role of handedness and sexual orientation as mediators of this effect. We compared the performance of LH (left-handed) and RH (right-handed) heterosexual and homosexual male and female participants on a face recognition(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)

The Immersive Virtual Human Exploration (IVHE) activity is exploring the potential of using fully immersive, 3D virtual environments to further exploration of the solar system. By producing interactive virtual environments based on collected sensor data, IVHE could expand human exploration to areas that are currently inaccessible to humans, promote(More)
