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...

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...
