“…Training programs vary in the degree to which the interventions rely on or target visual perceptual skills (Ball et al, 1988) versus cognitive abilities like memory (Rebok & Balcerak, 1989) or reasoning (Baltes & Willis, 1982).…”

Cognitive training improves mental abilities in older adults, but the trainability of persons with memory impairment is unclear. We conducted a subgroup analysis of subjects in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) trial to examine this issue. ACTIVE enrolled 2802 non-demented, community-dwelling adults aged 65 years and older and randomly assigned them to one of four groups: Memory training, reasoning training, speed-of-processing training, or no-contact control. For this study, participants were defined as memory-impaired if baseline Rey Auditory Verbal Learning Test (AVLT) sum recall score was 1.5 SD or more below predicted AVLT sum recall score from a regression-derived formula using age, education, ethnicity, and vocabulary from all subjects at baseline. Assessments were taken at baseline (BL), post-test, first annual (A1), and second annual (A2) follow-up. One hundred and ninety-three subjects were defined as memory-impaired and 2580 were memory-normal. Training gain as a function memory status (impaired vs. normal) was compared in a mixed effects model. Results indicated that memoryimpaired participants failed to benefit from Memory training but did show normal training gains after reasoning and speed training. Memory function appears to mediate response to structured cognitive interventions in older adults.

“…Over the last decade or so, researchers have established a connection between measures of visual attention and driving (Baldock, Mathias, McLean, & Berndt, 2007;Ball, Beard, Roenker, Miller, & Griggs, 1988). Particularly successful has been the Useful Field of View test (UFOV, Ball et al, 1988;Hoffman, McDowd, Atchley, & Dubinsky, 2005). However, while there are significant associations between UFOV and driving performance (Clay et al, 2005), ROC analysis (Bedard, Weaver, Darzins, & Porter, 2008) suggests that as a screening test it would produce unacceptable numbers of false positives (unsafe drivers categorized as safe) and/or false negatives (safe drivers categorized as unsafe).…”

Summary: Existing tests (e.g., useful field of view; UFOV) that are commonly used to evaluate visual attention when predicting at-risk drivers do not have a dynamic component. In this project, we developed a brief computerized test of dynamic visual attention (multiple object tracking; MOT). Estimates of threshold tracking speed from the brief MOT test showed good agreement with those determined by a full psychometric function (n = 41, r = 0.876, p < 0.001). The brief MOT test was then implemented in a clinical driving assessment program; participants with poorer MOT scores had higher error scores on the road test (n = 15, r = -0.670, p = 0.006).

“…Older adults have limited visual field and it may be caused by slow visual processing speed due to ageing [17]. The slow visual processing speed in older adults may affect visual attention as well, which was shown to be associated with mobility problems independently [18].…”

Older adults are more likely to be required to face the problems of deteriorating movement control due to ageing and poor visuomotor adaptation is believed to be one of the important contributors to the problems. Therefore, we assessed motor performance together with gaze behaviors in young and older adults when they were performing computer-based reaching tasks aiming to examine the potential impact of ageing on visuomotor behaviors and adaptation. In this study, visuomotor behaviors in computer-based reaching tasks were quantitatively evaluated under providing online visual feedback or blocking online visual feedback (simulated visual deficiency) conditions. Results revealed that ageing affects motor performance of the reaching tasks significantly in both visual feedback conditions. Older adults performed distinctive gaze behaviors when compared with the young adults. It implies that simulated visual deficiency in the blocking online visual feedback condition may work as a stimulus to cause extra perceptive load during movement execution and, more importantly, ageing induces slower visuomotor adaptation. Therefore, visual deterioration may slow down the process of visuomotor adaptation. Consequently, the results of present study provide us with new insights in how to further improve the Geriatric rehabilitative training methods for older adults in the context of augmenting visuomotor behaviors, for example, by utilizing a welldesigned errorless training methodology to enhance movement automaticity and visuomotor adaption during motor rehabilitation in Geriatric population.
