PSYCHOLOGICAL STRESSORS

Cognitive Appraisal Ethical Issues

Level of Arousal Figure 13.2 The Yerkes-Dodson law showing the relationship between level of arousal (induced by stress) and performance. The OLA is shown to be higher for less complex tasks.

Performance Changes with Overarousal Remediation of Psychological Stress

LIFE STRESS

WORKLOAD OVERLOAD

Workload The timeline model Figure 13.3 Timeline analysis. The percentage of workload at each point is computed as the average number of tasks per unit time, within each window. Shown at the bottom of the figure is the computed workload value TR/TA.

Mental Workload Measurement Primary task measures Secondary task methods Physiological measures Subjective measures Workload dissociations

FATIGUE AND SLEEP DISRUPTION

Vigilance and Underarousal Causes of the vigilance decrement Time Event salience Signal rate Arousal level Vigilance Remediations

Sleep Disruption Sleep Deprivation and Performance Effects Circadian Rhythms

Figure 13.5 Graph plotting mean sleep latency (top), circadian rhythms (body temperature), and sleep duration (Bottom) against time for two day-night cycles. The bars around sleep duration represent the variability.

Figure 13.6 Graph showing how performance on four kinds of tasks varies as a function of circadian rhythms, shown for a one day cycle.
