We argue that molecular visualization is a process that includes constructing a mental model. Current qualitative research has shown that participants working on a mental molecular visualization/rotation task invoke components of a mental model. Four of the components are static representations: referents, relations, results, and rules/syntax. The fifth component is dynamic: operation. Two exam...
The objective of this study was to assess an empirical approach to the characterisation of mental models in a multitasking scenario. A virtual reality task was used, in which participants were required to attend to and detect multiple types of perceptual events occurring randomly in time while carrying on steady physical activity (walking on a treadmill). Based on a cognitive task analysis, dif...
Mental workload is a key factor influencing the occurrence of human error, especially during piloting and remotely operated vehicle (ROV) operations, where safety depends on the ability of pilots to act appropriately. In particular, excessively high or low mental workload can lead operators to neglect critical information. The objective of the present study is to investigate the potential of fu...
Both physical and mental effort are thought to affect vigilance. Mental effort is known for its vigilance declining effects, but the effects of physical effort are less clear. This study investigated whether these two forms of effort affect the EEG and subjective alertness differently. Participants performed a physical task and were subsequently presented with a mental task, or vice versa. Ment...
