The Relationship

Abstract Objective Over the past fifty years, many traditional paper-and-pencil neuropsychological tests have been translated to new computerized devices (Canini et al., 2014). Virtual reality offers neuropsychologists an opportunity to observe patients’ neurocognitive functioning in an immersive, lifelike environment, rich in visual stimuli (Morganti, 2004), yet relatively little is known about the relationship between visual memory and performance on learning and memory tasks in virtual reality environments. The purpose of this study was to investigate, among older adults, the relationship between visual memory, as measured by a traditional paper-and-pencil test, and procedural learning and memory performance in a virtual reality environment simulating meal preparation tasks. Methods Older adults (N = 73) ages 55-90 (M = 72.77, SD = 7.87) were administered the Weschler Adult Intelligence Scale-Fourth Edition (WMS-IV) Visual Reproduction Immediate Recall and the Virtual Kitchen Protocol (VPK), a virtual reality-based measure of learning and memory for meal preparation tasks. Results Participants performance on the immediate portion of WMS-IV, visual reproduction, correlated with their performance on the VPK teaching trial (r = .65, p = 0.01), immediate recall (r = .51, p = 0.01), delayed recall (r = .58, p = 0.01), and forced choice recognition ( r = ..54, p = 0.01) of Job Sim. Conclusion Results suggest that visual memory aids healthy older adults in procedural learning and memory tasks in the Virtual Kitchen Protocol, a virtual reality environment simulating meal preparation tasks. These results suggest that visual memory ability is germane to performance in virtual reality environments that are rich in visual stimuli.

The Relationship

Abstract Background In older adults, the linkage between laboratory-assessed ‘motor capacity’ and ‘mobility performance’ during daily routine is controversial. Understanding factors moderating this relationship could help developing more valid assessment as well as intervention approaches. We investigated whether the association between capacity and performance becomes evident with transition into frailty, that is, whether frailty status moderates their association. Methods We conducted a cross-sectional analysis of the observational Arizona Frailty Cohort Study (ClinicalTrials.gov identifier: NCT01880229) in a community-dwelling cohort in Tucson, Arizona. Participants were N = 112 older adults aged 65 years or older who were categorized as non-frail (n = 40), pre-frail (n = 53) or frail (n = 19) based on the Fried frailty index. Motor capacity was quantified as normal (NWS) and fast walking speed (FWS). Mobility performance was quantified as 1) cumulated physical activity (PA) time and 2) everyday walking performance (average steps per walking bout; maximal number of steps in one walking bout), measured by a motion sensor over a 48 h period. Hierarchical linear regression analyses were performed to evaluate moderation effects. Results Unlike in non-frail persons, the relationship between motor capacity and mobility performance was evident in pre-frail and frail persons, confirming our hypothesis. A moderating effect of frailty status was found for 1) the relationship between both NWS and FWS and maximal number of steps in one bout and 2) NWS and the average steps per bout. No moderation was found for the association between NWS and FWS with cumulated PA. Conclusion In pre-frail and frail persons, motor capacity is associated with everyday walking performance, indicating that functional capacity seems to better represent mobility performance in this impaired population. The limited relationship found in non-frail persons suggests that other factors account for their mobility performance. Our findings may help to inform tailored assessment approaches and interventions taking into consideration a person’s frailty status.
