Abstract
This chapter investigates the effect of stress on cognitive load measurement using GSR as a physiological index of CL. The experiment utilises feelings of lack of control, task failure and social-evaluation to induce stress. The experiment described demonstrates that mean GSR can be used as an index of cognitive load during task execution, but that this relationship is obfuscated when test subjects experience fluctuating levels of stress. Alternate analysis methods are then presented that show how this confounding factor can be overcome.
