Process Entropy and Cognitive Control: Mental Load in Internalised Thought Processes

  • Peter Hamilton
Part of the NATO Conference Series book series (NATOCS, volume 8)

Abstract

‘Traditional’ information theory still has a good deal to offer us in our consideration of mental workload. It is clear even from early work on perceptual-motor skill that subjective expectations, coding strategies, learned S-R compatibilities and the like will remain the private province of the subject. In consequence the Holy Grail of an absolute measurement of task load remains unattainable. However, I believe that in the short term the rule does hold that mental workload is some function of the uncertainty the subject must resolve, and the rate at which he attempts to resolve it in pursuit of his goal.
