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...

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 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...
