Abstract:
A study was conducted to investigate the effects of heat stress on time-sharing performance. Twelve participants performed three dual-task scenarios and a multiple-task scenario for 2 h in each of six climates.

Abstract:
The authors wish to challenge the contemporary stress limits for workers exposed to adverse thermal conditions.
We report an experiment which investigated the performance and workloadeffects associated with the functional grouping of automated displays in a multi-task flight simulation. Eleven rated pilots performed tracking, systems monitoring, and target acquisition sub-tasks in manual conditions and when the targetingtask was automated.

Abstract:
(presented by Joel S. Warm) – The NASA TLX was used to assess subjective workload in the performance of comparative discrimination (simulations) and absolute discrimination (successive) vigilance tasks with high and low discriminability signals.
