Catastrophe Models for Cognitive Workload and Fatigue

  title={Catastrophe Models for Cognitive Workload and Fatigue},
  author={Stephen J. Guastello and Henry Boeh and Curt Shumaker},
We reconceptualised several problems concerning the measurement of cognitive workload – fixed versus variable limits on channel capacity, work volume versus time pressure, adaptive strategies, resources demanded by tasks when performed simultaneously, and unclear distinctions between workload and fatigue effects – as two cusp catastrophe models: buckling stress resulting from acute workload, and fatigue resulting from extended engagement. Experimental participants completed a task that was… CONTINUE READING
