An Initial Indigenous Comparative Analysis of Cognitive Assessment Tools for Cognitive Load Measurement of Workforce in Industry 4.0 Era

Abstract

With the evolution of industry, the way of working has changed dramatically around the globe. The focus is shifted to consider physical load and cognitive load simultaneously. And to assess cognitive load multiple tools have been used to assess the cognitive load (CL) i.e. performance based, physiological measures and subjective measures. However, in this article, the last one has been discussed. Three popular tools have been carried away named Subjective Work Load Assessment Method (SWAT),  NASA Task Load Index (NASA-TLX), and Cognitive Load Assessment Method (CLAM). On the basis of the results, it is quite evident that CLAM has a well-defined range of components to measure cognitive load which helps to do better cognitive load management. All these three tests have almost similar factors but CLAM has the advantage that it also describes CL caused by the work station design or orientation while SWAT’s main focus seems to be on the psychological and effort whereas NASA-TLX has batter significance while consider the physical and temperamental demand of the task which also have impact on the CL of a person.
