BACKGROUND Musculoskeletal disorders (MSDs) are a serious problem among the nursing staff. Mental workload is the major cause of MSDs among nursing staff. The aim of this study was to investigate the mental workload dimensions and their association with MSDs among nurses of Alzahra Hospital, affiliated to Isfahan University of Medical Sciences. MATERIALS AND METHODS This descriptive cross-sec...

The present study examined the sensitivity of several candidate metrics of real-time workload within the spatial component of an unmanned aerial vehicle (UAV) task. Advanced Brain Monitoring’s (ABM) wireless B-Alert system was used to collect participant’s EEG workload and engagement data. Eye tracking data was also collected. The UAV simulation required participants to report heading informati...

OBJECTIVE We evaluated a variety of non-invasive physiological technologies and a series of test approaches for examination of aviator performances under conditions of mental workload in order to provide a standard real-time test for physiological and psychological pilot fatigue assessments. METHODS Twenty-one male aviators were selected for a simulated flight in a hypobaric cabin with artifi...

Mental activity is a neglected factor in sleep research. The few investigations on sleep that manipulate prior mental activity are inconclusive with respect to the possible effects of mental activity on recovery. In the present study, the effects of two levels of mental activity on subsequent sleep were studied. Thirteen male subjects (range 18-28 years) participated in one lightly and two heav...

Functional Near-Infrared Spectroscopy (fNIRS) is a brain imaging technique that offers the potential to provide continuous, detailed insight into human mental workload, enabling an objective means of detecting overload conditions during complex tasks. When compared to other brain imaging techniques, fNIRS provides a non-invasive, portable and reliable measure that lends itself towards more ecol...

Modeling learners’ emotional states is a promising tool for enhancing learning outcomes and tutoring abilities. In this paper, we present a new perspective of learner emotional modeling according to two fundamental dimensions, namely mental workload and engagement. We hypothesize that analyzing results from learners’ workload and engagement evolution can help Intelligent Tutoring Systems diagno...

Predicting high pilot mental workload is important to the United States Air Force because lives and aircraft have been lost due to errors made during periods of ;ight associated with mental overload and task saturation. Current research e0orts use psychophysiological measures such as electroencephalography (EEG), cardiac, ocular, and respiration measures in an attempt to identify and predict me...

A market research company (Nielsen) reported that consumers in the Asia-Pacific region have become the most active group in online shopping. Focusing on augmented reality (AR), which is one of three major techniques used to change the method of shopping in the future, this study used a mixed design to discuss the influences of the method of online shopping, user gender, cognitive style, product...
