Useful field of view, a measure of processing speed and spatial attention, can be improved with training. We evaluated the effects of this improvement on older adults' driving performance. Elderly adults participated in a speed-of-processing training program (N = 48), a traditional driver training program performed in a driving simulator (N = 22), or a(More)
The purpose of the present investigation was to examine the impact of speed of processing training on the cognitive and everyday abilities of older adults with initial processing speed or processing difficulty. Participants were randomized to either a speed of processing intervention or a social- and computer-contact control group. Results indicate that(More)
The Useful Field of View test (UFOV(1)) is a measure of processing speed that predicts driving performance and other functional abilities in older adults. In comparison to a number of other visual and cognitive measures, the UFOV measure has consistently been found to be the strongest predictor of motor vehicle crashes of older adults. This measure has(More)
OBJECTIVES To evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision (MVC) involvement in a cohort of older drivers. DESIGN Prospective cohort study. SETTING Motor Vehicle Administration (MVA) field sites in Maryland. PARTICIPANTS Of the 4,173 older drivers invited to participate in the study,(More)
The Useful Field of View test (UFOV) is increasingly used in clinical and rehabilitation settings. To date there have been no normative data for adjusted performance comparisons across demographically-similar, elderly peers. This study examined demographic and cognitive influences on the UFOV in a sample of 2759 participants (65-94 years of age).(More)
BACKGROUND Age-related sensory and cognitive impairments have been related to functional performance in older adults. With regard to cognitive abilities, processing speed in particular may be strongly related to older adults' abilities to perform everyday tasks. Identifying and comparing cognitive correlates of functional performance is particularly(More)
OBJECTIVE To evaluate the relationship between sensory and cognitive decline, particularly with respect to speed of processing, memory span, and fluid intelligence. In addition, the common cause, sensory degradation and speed of processing hypotheses were compared. METHOD Structural equation modeling was used to investigate the complex relationships among(More)
Psychological, social, and health variables were compared in 175 Black and White family caregivers of patients with dementia and 175 Black and White noncaregivers. Caregivers and noncaregivers did not differ within race on demographic variables. Caregiving was associated with increased depression and decreased life satisfaction only in White families.(More)
OBJECTIVE To evaluate assumptions regarding semantic (noun), verb, and letter fluency in mild cognitive impairment (MCI) and Alzheimer disease (AD) using novel techniques for measuring word similarity in fluency lists and a region of interest (ROI) analysis of gray matter correlates. METHOD Fifty-eight individuals with normal cognition (NC, n=25), MCI(More)
OBJECTIVE Mild cognitive impairment (MCI) may involve subtle functional losses that are not detected with typical self- or informant-report assessments of daily function. Information about the nature of functional difficulties in MCI can be used to augment common clinical assessment procedures, and aspects of function that are affected in MCI can serve as(More)
