TY - JOUR PY - 2011// TI - A novel approach to the physiological measurement of mental workload JO - International journal of psychophysiology A1 - Miller, Matthew W. A1 - Rietschel, Jeremy C.

SP - 75 EP - 78 VL - 80 IS - 1 N2 - While performing a visuo-motor task under incrementally-varied levels of difficulty, individuals were probed with a variety of novel, task-irrelevant, auditory stimuli. To determine the effect of task load on cerebral-cortical processing of these stimuli, event-related potentials were recorded while participants performed the task. We found that N1, P2, P3 and late positive potential (LPP) component amplitudes were inversely related to task-difficulty. This suggests that a variant of the oddball paradigm--in which the stimulus stream comprises novel sounds--is capable of providing a reliable index of mental workload.
