Mental workload is often measured using multidimensional measures which aim to identify a “redline” or region of “overload” when operator performance is jeopardized by overwhelming levels of cognitive demand. This chapter addresses two issues in this field: the role of motivation in mental workload research, particularly with respect to the quantification of workload “red lines,” and the use of composite measures to describe the interaction between performance and neurophysiological activation as an index of neural efficiency. Two studies are summarized where participants experienced various levels of working memory load, from easy to impossible levels of task demand. The first manipulated extrinsic motivation (financial reward) alongside working memory load and measured theta power at the frontal–medial location. The second study assessed brain activation with respect to neurovascular activation (via functional near-infrared spectroscopy) in response to working memory load. Data is provided to demonstrate the sensitivity and potential benefit of neural efficiency as a neuroergonomic index of mental workload.
