Abstract
This study empirically investigated the effects of static postural loading on the performance of basic short-term/working memory (STM/WM) tasks. Four posture groups varying in the magnitude of postural loading were considered. Each group corresponded to one of the four action categories of the OWAS posture classification scheme and consisted of three postures belonging to the action category. Three STM/WM tasks, the Corsi block-tapping, digit span, and 3-back tasks, were considered to examine the visuo-spatial sketchpad, phonological loop, and central executive sub-systems of WM. Thirty participants conducted the STM/WM tasks while statically holding each of the twelve postures. Friedman test results revealed that postural loading significantly affected the STM/WM task performance for each of the three experimental tasks (p < .001). The current study findings may help understand the impacts of postural loading on the worker's concurrent cognitive task performance in various physical-cognitive dual task situations.
期刊介绍:
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
