Measure Of Performance

BackgroundCognitive and visual impairments are common in Parkinson’s disease (PD) and contribute to gait deficit and falls. To date, cognition and vision in gait in PD have been assessed separately. Impact of both functions (which we term ‘visuo-cognition’) on gait however is likely interactive and can be tested using visual sampling (specifically saccadic eye movements) to provide an online behavioural measure of performance. Although experiments using static paradigms show saccadic impairment in PD, few studies have quantified visual sampling during dynamic motor tasks such as gait.This article describes a protocol developed for testing visuo-cognition during gait in order to examine the: 1) independent roles of cognition and vision in gait in PD, 2) interaction between both functions, and 3) role of visuo-cognition in gait in PD.Methods Two groups of older adults (≥50 years old) were recruited; non-demented people with PD (n=60) and age-matched controls (n=40). Participants attended one session and a sub-group (n=25) attended two further sessions in order to establish mobile eye-tracker reliability. Participants walked in a gait laboratory under different attentional (single and dual task), environmental (walk straight, through a door and turning), and cueing (no visual cues and visual cues) conditions. Visual sampling was recorded using synchronised mobile eye-tracker and electrooculography systems, and gait was measured using 3D motion analysis.Discussion This exploratory study examined visuo-cognitive processes and their impact on gait in PD. Improved understanding of the influence of cognitive and visual functions on visual sampling during gait and gait in PD will assist in development of interventions to improve gait and reduce falls risk. This study will also help establish robust mobile eye-tracking methods in older adults and people with PD.

Written Description

The purpose of the present study was to assess the benefits of providing on-line training for an automatic teller machine (ATM). An ATM simulator was developed for the study, and older adults (65-80) served as the subjects. Subjects were assigned to one of two conditions. Half of the subjects were given a written description of how the ATM worked. The other half went through an on-line tutorial, which showed them how to perform transactions on the simulator. After performing 30 transactions on the simulator, subjects were transferred to a new ATM simulator that was topographically different. The subjects who received the on-line tutorial performed more transactions correctly during acquisition, and were better able to transfer their skills to a different ATM simulator and to novel transactions.

Anxiety Condition

Abstract Objectives Older adults anxious about falling will often consciously process walking movements in an attempt to avoid falling. They also fixate their gaze on the present step rather than looking ahead to plan future actions. The present work examined whether conscious movement strategies result in such restricted visual planning. Methods A total of 18 community-dwelling older adults (agemean = 71.22; SD = 5.75) walked along a path and stepped into two raised targets. Repeated-measures analyses of variance were used to compare gaze behavior and movement kinematics when participants walked: (a) at baseline (ground level); (b) under conditions designed to induce fall-related anxiety (walkway elevated 0.6 m); and (c) in the absence of anxiety (ground level), but with explicit instructions to consciously process movements. Results Participants reported increased conscious movement processing when walking both on the elevated walkway (fall-related anxiety condition) and at ground level when instructed to consciously process gait. During both conditions, participants altered their gaze behavior, visually prioritizing the immediate walkway 1–2 steps ahead (areas needed for the on-line visual control of individual steps) at the expense of previewing distal areas of the walking path required to plan future steps. These alterations were accompanied by significantly slower gait and increased stance durations prior to target steps. Conclusions Consciously processing movement (in the relative absence of anxiety) resulted in gaze behavior comparable to that observed during conditions of fall-related anxiety. As anxious participants also self-reported directing greater attention toward movement, this suggests that fall-related anxiety may disrupt the visual control of gait through increased conscious movement processing.

Previous research showed associations between personality traits and eye movements of young adults in the laboratory. However, less is known about these associations in real life and in older age. Primarily, there seems to be no paradigm to assess eye movements of older adults in real life. The present feasibility study thus aimed to test grocery shopping as a real-life assessment paradigm with older adults. Additionally, possible links between personality traits and eye movements were explored. The sample consisted of 38 older individuals (M = 72.85 years). Participants did their grocery shopping in a supermarket while wearing an eye tracker. Three key feasibility issues were examined, that is (1) wearability of the eye tracker during grocery shopping, (2) recording, and (3) evaluation of eye movements in a real-life context. Our real-life assessment paradigm showed to be feasible to implement and acceptable to older adults. This feasibility study provides specific practical recommendations which may be useful for fu-ture studies that plan to innovatively expand the traditional methods repertoire of personality science and aging research by using eye tracking in real life.

Perfect Storm

Abstract COVID-19 created a “perfect storm” for financial exploitation directed at older adults. We invited adults aged 60 and older enrolled in gerontology research registries at Virginia Tech, Florida State University, Wayne State University, and University of Pittsburgh to complete an on-line survey about experiences with financial exploitation by strangers. The 997 respondents ranged in age from 60 to 98 (M = 71.3; SD = 6.8); most identified as White (93.4%), female (64.2%) and living with a spouse/partner (58%). Approximately one-half of respondents (56.87%) reported experiencing a scam attempt about COVID-19 issues. Most contact by scammers was electronic (49%) and frequently occurred two or more times (40%). Most respondents ignored the request (i.e., hung up phone, deleted text/email, threw away mail). However, 9% sent the requested payment, and 4% gave the scammer their personal information. Confidence in financial matters and having attended financial educational programs protected older adults from being scammed.
