Towards a model of stress and human performance

Sleep loss may cause malfunctioning of arousal and activation. If this malfunctioning is not corrected by effort, there is a decrement in the performance.

“Sleep loss may cause malfunctioning of arousal and activation. If this malfunctioning is not corrected by effort, there is a decrement in the performance (Sanders, 1983).”

Generally, reaction time variability decreases during faster event rates for all children.

“Generally, RTV decreases during faster ERs for all children [41,83,84].”

The effort system is under the control of an evaluation mechanism that scans the momentary state of the arousal and activation levels.

“The effort system is under control of an evaluation mechanism (with many features in common with executive control systems in other models), which scans the momentary state of the arousal and activation levels.”

When task duration is short and subjects are motivated, stimulus degradation, set-size, and response compatibility manipulations affect the stimulus encoding, central processes, and motor preparation stages in predictably different ways.

“For instance, when the task duration is short and when subjects are motivated, stimulus degradation, set-size, and response compatibility manipulations affect the stimulus encoding, central processes and motor preparation stages in predictably different ways.”
