Results were insignificant after adjusting for secondary task performance.
We also used mixed models (PROC MIXED) to test the effects of driving demands on the overall NASA-TLX and ratings for secondary task performance.
Risks will be calculated for engaging in secondary tasks, looking away from the road, being drowsy and driving riskily.
Some control frameworks are not optimal, that is they do not find the optimal solution for the secondary tasks.
Situation awareness regarding patient data, workload, responses to system failures, and performance on secondary tasks was measured for two groups of experienced ED staff (nurses, and clerks) across two display conditions and two patient volume conditions.
They reinforced text presented in the informed consent form where it was stated that the monetary award for performing the secondary tasks could be up to $10; in reality, all participants received equal compensation regardless of performance.
For the secondary task but not for the prioritized motor task, these relative single case effect sizes proved to be positively (and significantly) correlated with the number of met-alleles on the COMT-genotype, rs = .553; p = .004.004
The approach centers on the integration of two computational behavioral models, one for the primary task and another for the secondary task.
In this system, the participants' performance both for the main task (simulated by simple arithmetic problems) and for the secondary task (a simulation of a production process) can be measured in a more fine-grained manner than has been the case for existing research in this field.
Specifically, Marchand and Courty define different secondary tasks for controlling a camera in virtual environments [9].
