Developing decision support for cybersecurity threat and incident managers

Cybersecurity threat and incident managers in large organizations, especially in the financial sector, are confronted more and more with an increase in volume and complexity of threats and incidents. At the same time, these managers have to deal with many internal processes and criteria, in addition to requirements from external parties, such as...

Towards user-adapted training paradigms: Physiological responses to physical threat during cognitive task performance

Feedback of physiological responses have a great potential to support virtual training paradigms aimed to increase cognitive task performance under stressful threatening conditions. In the current study, we examined the sensitivity of a range of physiological indicators derived from electrodermal activity (EDA), blood pressure (BP) and heart...

Towards a Mixed Reality Platform for Applied Cognitive Load Evaluation

Physical load experienced by dismounted military has already been studied extensively. Few studies, however, have focused on the cognitive load of dismounted soldiers during military operations in the field. In this project, a cognitive task analysis (CTA) was performed to study the cognitive workload of a troop commander during troop hasty...

Work content influences on cognitive task load, emotional state and performance during a simulated 520-days' Mars mission

In high-risk domains such as human space flight, cognitive performances can be negatively affected by emotional responses to events and conditions in their working environment (e.g., isolation and health incidents). The COgnitive Performance and Error (COPE) model distinguishes effects of work content on cognitive task load and emotional state,...

The effect of task load on the occurrence of cognitive lockup in a high-fidelity flight simulator

Motivation To analyse human errors and determine the underlying reason for these errors, in particular by investigating the error production mechanism cognitive lockup. Research approach A within subjects experiment has been conducted with 16 pilots in a high-fidelity and realistic environment. The independent variables were the cognitive task...

Developing a model of cognitive lockup for user interface engineering

This paper presents the development of a cognitive model of cognitive lockup: the tendency of humans to deal with disturbances sequentially, possibly overseeing crucial data from unattended resources so that serious task failures can appear—e.g., in a cockpit or control centre. The proposed model should support the design and evaluation of user...

Using a knowledge elicitation method to specify the business model of a human factors organization

Concept Mapping was used to structure knowledge elicitation interviews with a group of human factors specialists whose goal was to describe the business model of their Department. This novel use of cognitive task analysis to describe the business model of a human factors organization resulted in a number of Concept Maps on topics such as...

Drivers' reactions to sudden braking by lead car under varying workload conditions; towards a driver support system

At urban intersections drivers handle multiple tasks simultaneously, making urban driving a complex task. An advanced driver assistance system may support drivers in this specific driving task, but the design details of such a system need to be determined before they can be fully deployed. A driving simulator experiment was conducted to...

Measuring cognitive task load on a naval ship: Implications of a real world environment

Application of more and more automation in process control shifts the operator’s task from manual to supervisory control. Increasing system autonomy, complexity and information fluctuations make it extremely difficult to develop static support concepts that cover all critical situations after implementing the system. Therefore, support systems...

Cognitive task load in a naval ship control centre: From identification to prediction

Deployment of information and communication technology will lead to further automation of control centre tasks and an increasing amount of information to be processed. A method for establishing adequate levels of cognitive task load for the operators in such complex environments has been developed. It is based on a model distinguishing three...

Method for development of human behaviour models for simulation based training

There is a growing interest in Human Behavior models for training purposes. The reason for this is twofold: Firstly, the cost of training will drop by using cognitive agents as team members or adversaries, because the number of human participants will decrease. Secondly, cognitive agents can enhance training effectiveness. Therefore a new...

Cognitive task load analysis: Allocating tasks and designing support

We present a method for Cognitive Task Analysis that guides the early stages of software development, aiming at an optimal cognitive load for operators of process control systems. The method is based on a practical theory of cognitive task load and support. In addition to the classical measure percentage time occupied, this theory distinguishes...

Cognitive task load and support on a ship's bridge: Design and evaluation of a prototype user interface

Recently, four cognitive support concepts were developed, that should help to handle high-y demand situations. These concepts are based on a cognitive task load model and can be realised with a specific method for cognitive task load analysis. The model and method describe task load in terms of three behavioural factors: the percentage time...

Cognitive task analysis and innovation of training: The case of structured troubleshooting

Troubleshooting can often be a time consuming and difficult activity. The question how the training of beginning technicians can be improved was the starting point of the research described in this article. A cognitive task analysis was carried out consisting of two preliminary observational studies on troubleshooting in naturalistic settings,...

State-of-the-art review of cognitive task analysis techniques

Training of systematic diagnosis: A case study in electronics troubleshooting

Two studies were carried out with the aim of developing better training methods for Naval maintenance technicians. The first study showed that novices experienced diffi-culties in two areas: 1. accessing relevant domain knowledge in particular problem solving phases (e.g., generating causes, testing causes); 2. keeping track of where they are in...
