Poor working postures and task demands are common factors that affect human performance in a workplace , particularly in the industrial sector (i.e., assembly tasks). These factors can lead to performance deterioration and introduce musculoskeletal disorders (MSDs). The current research study examines the interaction effects of working postures and assembly task demands on human performance and...

The present work is a quality-quantitative study of cause-effect type. The objective of this study was to investigate the effect of a Labor Gym (LG) program in mental workload of workers from rectory of the Universidade Estadual do Oeste do Paraná (Unioeste) Cascavel. The sample consisted of 35 employees. For data collection, it was used the NASA-TLX questionnaire to evaluate the mental workloa...

Dietary components may affect brain function and influence behaviour by inducing the synthesis of neurotransmitters. The aim of the present study was to examine the influence of consumption of a whey protein-containing breakfast drink v. a carbohydrate drink v. control on subjective and physiological responses to mental workload in simulated work. In a randomised cross-over design, ten healthy ...

A series of three field experiments were conducted to evaluate the level of autonomous mobility for the Army’s Experimental Unmanned ground Vehicle (XUV), during which an assessment of operator mental workload was performed. Workload data collection methods employed were the “NASA Task Load Index”, the “Overall Workload” scale, and experimenter observation during partially autonomous operations...

This study investigates the effects of thinking aloud on cognitive effort in translation as a function source-text difficulty level. It does so by considering time task, duration different phases (i.e., orientation, draft, revision), processing source and target texts, quality. Twenty participants took part an English–Chinese experiment, which comprised two matched sessions – translating while ...

A preliminary set of analyses are presented, where workload was examined in 32 adults infected with the human immunodeficiency virus (HIV). Like current COVID-19 pandemic (caused by SARS-CoV-2 virus), HIV can produce a wide variety symptoms, including various levels cognitive dysfunction. In fact, recent meta-analysis estimates that 39 million globally HIV, 42.6% exhibit some form HIV-associate...

Criminal investigative work entails a diverse array of tasks and responsibilities, ranging from interviewing suspects victims to managing the paperwork necessary follow-ups for each case. The present study sought evaluate workload impacts police investigators in metropolitan agency. NASA-Task Load Index (NASA-TLX), well-established human factor measure workload, was administered on 759 as quant...
