However, visuospatial attention measures during walking remained under-explored. Current studies introduced a newly-developed Standing and Walking Visual Attention Field (SWAVF) task to assess visuospatial attention during walking and examined its reliability, validity, and stability. Thirty young adults completed a traditional computerized Attention Visual Field (AVF) task while sitting, and the SWAVF task under walking and standing settings. Nine participants also performed the SWAVF task under additional distraction conditions. Results showed good split-half reliability during standing (r = 0.70) and walking (r = 0.69), moderate concurrent validity with the sitting AVF task (r = 0.42), moderate convergent validity between the standing and walking settings (r = 0.69), good construct validity, and moderate rank-order stability (r = 0.53). Overall, the SWAVF task showed good psychometric properties. Potential applications to the evaluation of prosthetic and other exoskeleton devices, smart glasses, and ground-level traffic lights or signs were discussed.}, journal={APPLIED ERGONOMICS}, publisher={Elsevier BV}, author={Yuan, Jing and Bai, Xiaolu and Driscoll, Brendan and Liu, Ming and Huang, He and Feng, Jing}, year={2022}, month={Oct} }

Prostheses wearers’ adaptation processes are subjective and the efficiency largely depends on one’s mental processes. Therefore, beyond physical motor performance, prosthesis personalisation should consider the wearer’s preference and cognitive performance during walking. As a first step, it is necessary to examine the current measures of cognitive performance when a wearer walks with an LL prosthesis, identify the gaps and methodological considerations, and explore additional measures in a walking setting. In this protocol, we outlined a scoping review that will systematically summarise and evaluate the measures of cognitive performance during walking with and without LL prosthesis.Methods and analysisThe review process will be guided and documented by CADIMA, an open-access online data management portal for evidence synthesis. Keyword searches will be conducted in seven databases (Web of Science, MEDLINE, BIOSIS, SciELO Citation Index, ProQuest, CINAHL and PsycINFO) up to 2020 supplemented with grey literature searches. Retrieved records will be screened by at least two independent reviewers on the title-and-abstract level and then the full-text level. Selected studies will be evaluated for reporting bias. Data on sample characteristics, type of cognitive function, characteristics of cognitive measures, task prioritisation, experimental design and walking setting will be extracted.Ethics and disseminationThis scoping review will evaluate the measures used in previously published studies thus does not require ethical approval. The results will contribute to the advancement of prosthesis tuning processes by reviewing the application status of cognitive measures during walking with and without prosthesis and laying the foundation for developing needed measures for cognitive assessment during walking. The results will be disseminated through conferences and journals.}, number={2}, journal={BMJ OPEN}, author={Yuan, Jing and Cline, Emily and Liu, Ming and Huang, He and Feng, Jing}, year={2021} }

Despite established effectiveness, in-person on-road assessment and rehabilitation are expensive, and limited professional service may not be readily accessible; simulator-based training may not fit every driver due to simulator sickness. In comparison, computerized training is easier to implement and could be delivered with little cost to older drivers with computer access. Based on the Drive Aware Task, a validated measure of attentional processes in hazard detection, we developed a computerized cognitive training method with a focus on hazard detection. In this study, we examined the effectiveness of this newly-developed interactive training program in improving older drivers’ detection of road hazards. Methods Using a matched-pair design, nine triads of three older drivers (aged 65 or above) with matched pretest performance and gender were formed. For each triad, each participant was randomly allocated to one of the three groups: 1) active training group to receive the two training sessions (1.5–2.5h per session); 2) passive training group to receive two video-watching sessions (i.e., watch the video of training session performance from the corresponding paired participant); 3) no-contact control group. Older drivers’ performances on hazard detection and simulated driving were measured before and after training. Results The active training group showed significant training effects on the computerized hazard detection task and simulated driving performance, while there were only marginal effects in the passive training group and no effects in the no-contact control group. A post-training survey suggested older drivers were receptive to the Drive Aware training program. Conclusions The computerized Drive Aware training program has the potential to be used as a prevention and intervention tool to improve older drivers’ hazard detection performance. Future studies should examine the effectiveness of this tool in more diverse samples and in long-term outcomes.}, journal={TRAFFIC INJURY PREVENTION}, author={Yuan, Jing and Crowson, Aaron and Richardson, Geoffrey and Feng, Jing}, year={2021}, month={May} }
 @article{yuan_gruhn_2021, title={Time Effects of Informal Caregiving on Cognitive Function and Well-Being: Evidence From ELSA}, volume={61}, ISSN={["1758-5341"]}, DOI={10.1093/geront/gnaa114}, abstractNote={Abstract
               
                  Background and Objectives
                  As informal caregiving becomes prevalent, its consequences for caregivers’ cognitive and socioemotional functioning gain more importance for society. There are inconsistent findings regarding the direction of the impact of caregiving—whether caregiving maintains or compromises functioning—and the impact of time—whether the effects accumulate or are stable. In this study, we elucidated 3 time effects of caregiving—concurrent, cumulative, and lagged effects—on cognitive and socioemotional functioning.
               
               
                  Research Design and Methods
                  We used data from Wave 1 (2002–2003) to Wave 8 (2016–2017) in the English Longitudinal Study of Ageing (ELSA) and latent growth curve models with the time-varying predictor to investigate 3 time effects of caregiving on cognitive function (memory and executive function) and well-being (life satisfaction and quality of life).
               
               
                  Results
                  Over and beyond age effects, current caregiving (concurrent effect) was related to worse well-being and better delayed recall. Little robust cumulative effect was found on cognition and well-being. In addition, there were significant and differential lagged effects of caregiving after controlling for concurrent and cumulative effects; that is, caregiving was related to worse well-being and better memory functioning 2–4 years later.
               
               
                  Discussion and Implications
                  The differential concurrent and lagged effects of caregiving on cognitive and socioemotional functioning suggest separate mechanisms for different domains of functioning. The nonsignificant cumulative effects but significant lagged effects imply that even one-time caregiving has long-term (2–4 years) consequences for the caregiver’s future functioning, and the mechanism of long-term caregiving effects may be more qualitative than quantitative.
