Abstract
Background: The ageing workforce is increasing in today's work environments, bringing unique challenges related to productivity and workload management especially in adapting into modern technology and high cognitive workload demands. The demands of modern work systems often worsen workload levels among ageing office workers, potentially affecting their performance and well-being.
Objectives: This study explores the potential of Cognitive Ergonomic-Driven Technology (CEDT) as an intervention to mitigate workload and enhance work performance in ageing office workers.
Method: The experiment involved the application of CEDT during task performance for both managerial and supporting staff. Performance metrics, Heart Rate measures, electroencephalogram (EEG) based Beta-Alpha Ratio (BAR)-measuring cognitive workload, and NASA Task Load Index (TLX)-measuring overall workload, all workload metrics were measured before and after the intervention. BAR is measuring the thirty participants involved in this study, evenly split between managerial and supporting staff.
Result: The results demonstrate significant improvements in performance scores (PS) and reductions in strain indicators such as heart rate and BAR following the CEDT intervention. Correlation analysis revealed that effort demand (r = -0.542, p < 0.05) was a key factor influencing arithmetic task (task II) outcomes for managerial staff, while performance demand (r = -0.718, p < 0.01) was more critical for supporting staff in typing task (task I).
Conclusion: These findings indicate that CEDT can enhance work performance and reduce workload among ageing workers, with varying impacts depending on the job role. Practical implementation may face challenges, including potential resistance to technology and cost implications, especially among ageing workers. Future research should explore long-term effects, particularly regarding cognitive fatigue and adaption over time, as well as the customization of CEDT for different job roles.
背景：在当今的工作环境中，老龄化的劳动力正在增加，给生产力和工作量管理带来了独特的挑战，特别是在适应现代技术和高认知工作量需求方面。现代工作系统的要求往往会加重老年上班族的工作量水平，潜在地影响他们的工作表现和幸福感。目的：本研究探讨认知工效学驱动技术（认知工效学驱动技术，CEDT）作为一种干预手段，减轻老年上班族的工作量并提高其工作绩效的潜力。方法：对管理人员和后勤人员在任务绩效中的应用进行了实验研究。表现指标、心率测量、基于脑电图（EEG）的β - α比（BAR）测量认知工作量和NASA任务负荷指数（TLX）测量总体工作量，在干预前后测量所有工作量指标。BAR正在测量参与这项研究的30名参与者，平均分为管理人员和支持人员。结果：结果显示，在CEDT干预后，表现得分（PS）显著提高，心率和BAR等应变指标降低。相关分析显示，努力需求（r = -0.542, p r = -0.718, p）能够提高老龄员工的工作绩效，减少工作量，但其作用因工作角色的不同而不同。实际实施可能面临挑战，包括对技术的潜在抵制和成本影响，特别是在老龄工人中。未来的研究应该探索长期影响，特别是关于认知疲劳和适应随着时间的推移，以及为不同的工作角色定制CEDT。
期刊介绍：
WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal''s subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
