Abstract:

Although SWAT and NASA-TLX workload scales have been compared on numerous occasions, they have not been compared in the context of transport operations. Transport pilot workload has traditionally been classified as long periods of low workload with occasional spikes of high workload. Thus, the relative sensitivity of the scales to variations in workload at the low end of the scale were evaluated. This study was a part of a larger study which investigated workload measures for aircraft certification, conducted in a Phase II certified Link/Boeing 727 simulator. No significant main effects were f

Abstract:

PT Muliaglass Float Division, a subsidiary of PT Mulia Industrindo, operates in the glass and ceramic industry with a large production capacity every day. Therefore, it is necessary to analyze the extent of psychological stress and what factors affect it. One way to measure mental workload is NASA-TLX. The National Aeronautics and Space Administration Task Load Index (NASA-TLX) is used to assess emotional mental load. The NASA TLX method is a mental workload measurement method that measures workload by dividing it into six aspects of work elements. NASA-TLX is divided into two phases. That is,

The present study examines the possible impact of the peak-end rule as it applies to the measurement of subjective workload. Researchers presented participants with the same three tasks presented in a different order and asked participants to rate the workload of the entire session using a single item rating scale and the NASA-TLX. One of the three tasks was designed to be more challenging than the other two as confirmed by a manipulation check. When the challenging task was presented last in the session, there were significantly higher ratings on the TLX-mental demand and TLX-effort subscales

Objective: This study reports on an initial test using a validated workload measurement method, the NASA Task Load Index (TLX), as an indicator of joint emergency exercise effectiveness. Prior research on emergency exercises indicates that exercises must be challenging, ie, result in high workload, to be effective. However, this is often problematic with some participants being underloaded and some overloaded. The NASA TLX was used to test for differences in workload between commanders and subordinates and among three different emergency response organizations during a joint emergency exercise

Abstract:

Vigilance refers to the ability of an observer to detect signals over a prolonged period of time. An important component of vigilance is the performance decrement, in which a decline in the correct detection of critical signals occurs as a function of time on task (e.g., Becker, Warm, Dember, & Howe, 1994). Typically, this decline in performance is accompanied by high perceived workload and stress (Warm, Parasuraman, & Matthews, 2008). One problem with traditional measures of mental workload, however, is these measures do not always converge on a single factor of workload. Instead, ana

Objective:The Dunning-Krueger effect is a cognitive bias where individuals tend to overestimate their abilities in areas where they are less competent. The Cordoba Naming Test (CNT) is a 30-item confrontation naming task. Hardy and Wright (2018) conditionally validated a measure of perceived mental workload called the NASA Task Load Index (NASA-TLX). Researchers reported that workload ratings on the NASA-TLX increased with increased task demands on a cognitive task. Anxiety is known as an emotion that can make an individual more susceptible to develop a mental health condition. We examine if t

Analog, full-scope, full-scale simulators with the fidelity to simulate all of the physical and underlying thermodynamics in the real system are representative of training simulators used by current operating nuclear power plants. However, digital simulators are becoming desirable to researchers and utility companies alike due to their increased accessibility and the capability of integrating new system upgrades.

Abstract:

Endoscopic surgery–a procedure wherein a target organ is displayed on a monitor and physicians use graspers to manipulate the tissue - has benefits for patients in terms of reduced blood loss, infection, and pain. However, physicians' informal reports indicate that this type of surgery is challenging to perform. These challenges arise from the need to view the target tissue on a monitor, resulting in reduced depth information as well as a disruption of the normal hand-eye mapping. This study represents the initial experimental effort to assess the workload demands experienced in an endoscopic

Across disciplines, the NASA Task Load Index (TLX) has been used as a subjective measure of workload. It quantifies six dimensions of work (mental, physical, and temporal demands, frustration, effort, and performance) on a scale of 1-100 scale, with scores >55 (i.e. overworked) associated with lesser performance.

Remote ischemic conditioning (RIC), where brief cycles of ischemia–reperfusion in a limb are induced to protect the brain, is a promising treatment for this setting. We assessed the usability of a novel RIC system in a simulated emergency response scenario.

In comparison to laparoscopic surgery, robot-assisted surgery is expected to reduce surgeon fatigue due to ergonomic adjustments, comfortable sitting positions, minimal restriction of instrument movement, and stable visualization.

In the present study, we have modified two of the original six items, Frustration and Performance, to better reflect workload by replacing them with Emotional Demand and Performance Monitoring Demand items. Confirmatory factor analyses indicate the new scale is an improvement but Physical Demand should also be considered for removal; this results in a five-

This study examined the effects of transitions in task demand on vigilance performance and perceived mental workload. Task demand was manipulated through variations in background event rate–the rate of cascade of neutral events which must be monitored in order to detect critical signals. As is typical in vigilance research, overall performance varied inversely with event rate in all phases of the study. The post-transition performance of observers shifted from a fast-to-slow event rate (high-to-low task demand) remained below that of their continuous slow event rate controls, and was thus unaf
