Interaction of task difficulty, activation, and work load

H Sjöberg

    Journal of Human Stress
    |March 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Physiological activation impacts reaction task performance. Optimal performance depends on task difficulty, with more complex tasks benefiting from lower activation levels, aligning with the Yerkes-Dodson law.

    Area of Science:

    • Physiology
    • Human Performance
    • Psychology

    Background:

    • The Yerkes-Dodson law suggests an inverted-U relationship between arousal and performance.
    • Understanding optimal activation levels is crucial for tasks requiring rapid responses.

    Purpose of the Study:

    • To investigate the relationship between physiological activation and performance in reaction tasks of varying complexity.
    • To determine if the Yerkes-Dodson law applies to psychomotor performance under different workload conditions.

    Main Methods:

    • Twenty-five subjects performed three reaction tasks with differing complexity levels.
    • Physiological activation was manipulated using five different workloads on a bicycle ergometer.
    • Heart rate and blood pressure were monitored as indicators of physiological activation.

    Main Results:

    • Performance varied across tasks and activation levels.
    • Results supported the Yerkes-Dodson law, showing an optimal activation level for performance.
    • More difficult tasks were associated with better performance at lower physiological activation levels.

    Conclusions:

    • The optimal level of physiological activation for rapid performance is task-dependent.
    • Task complexity moderates the relationship between activation and performance, as predicted by the Yerkes-Dodson law.
