The paper is aimed at studying the perceived strain in professional air-traffic controllers both through self-evaluation and physiological indicators from the autonomic nervous system (ANS). The number of aircraft to be monitored was the main independent variable and could evolve at random within 1 and 10. Five ANS variables were recorded continuously in 25 participants while they handled real ...

Mental workload and mind-wandering are highly related to driving safety. This study investigated the relationship between mental workload and mind-wandering while driving. Participants (N = 40) were asked to perform a car following task in driving simulator, and report whether they had experienced mind-wandering upon hearing a tone. After driving, participants reported their workload using the ...

Significant research has been dedicated to the development of creativity support tools, tools intended to amplify human creativity in the arts, sciences, and design disciplines. While examples of such tools abound, instruments are generally lacking to systematically and reliably assess these tools’ impact on the creative process. Without these instruments, it is difficult to identify what aspec...

Virtual models are a common instructional tool used in chemistry education to help students learn about the 3D structure of molecules. The present study examined effects of two interface design features on participant performance during a molecule orientation task. The features examined were 1) colocation of the visual and haptic workspace and 2) stereoscopic viewing. The results indicate that ...

This paper examines various control locations in heavy mining vehicles. Three trucks have been tested on a skid pad in both clockwise and anticlockwise directions. The skid lengths were measured after each trial. The primary focus of the study was the positioning of various controls and their relevance to various skid lengths. Some additional measures such as NASA-TLX scales were also used to m...

The purpose of this study was to identify the influence of situation complexity and driving experience on subjective workload and driving performance, and the less costly and the most effective strategies faced with a hazard pedestrian crossing. Four groups of young drivers (15 traditionally trained novices, 12 early-trained novices, 15 with three years of experience and 15 with a minimum of fi...

Research seeking to improve the measurement of workload requires the use of established task load manipulations to impose varying levels of demand on human operators. The present study sought to establish task load manipulations for research utilizing realistically complex task environments that elicit distinct levels of workload (i.e. low, medium, and high). A repeated measures design was used...

Intrusion detection systems are common in contemporary enterprises. These systems are sometimes operated by a single individual as a part time activity; they are sometimes operated by cyber security operation centres in which a group of technology experts with the sole task of monitoring, detecting, analysing and responding to threatening events in the computer network. In either case, human fa...

The role of humans in aviation and other domains continues to shift from manual control to automation monitoring. Studies have found that humans are often poorly suited for monitoring roles, and workload can easily spike in offnominal situations. Current workload measurement tools, like NASA TLX, use human operators to assess their own workload after using a prototype system. Such measures are ...

The research was conducted to compare the impacts of problem-based learning (PBL) and example-based learning (EBL) on the learning performance in an engineering domain. The research was implemented by means of experimental design. Specifically, a two-group experiment with a preand post-test design was used in this research. A total of 37 students were randomly assigned to PBL and EBL groups. A ...
