This article is a selective theory-driven review that synthesizes recent neuroscience findings concerning mental workload during complex cognition from the perspective of a functional resource theory called 3CAPS, focusing on the concept of capacity utilization . Capacity utilization refers to the proportion of resources that is being consumed in a given time interval in a given cognitive system. This definition integrates the dynamic effects of (a) the computational demand imposed by a task, and (b) the resource supply in an individual that is available to meet that demand. The analysis reveals that the functional relations between capacity utilization and measures of neural activity are similar across three different cognitive systems (language comprehension, visuospatial processing and executive processing). The measures of neural activity include functional neuroimaging, pupillary dilation and event-related potentials. The construct of capacity utilization provides a mapping between a functional architecture of cognition and aspects of its neural implementation.

Neuroergonomics: Research and practice (2003, unknown): “…and oculomotor control, and manual performance—are each discussed from a neuroergonomic perspective in other papers in the two special issues on neuroergonomics in this journal, by Just et al. (2003), Kramer and McCarley (2003) and Karwowski, Siemionow and Gielo-Perczak (2003), respectively.”
Pupil dilation as an index of effort in cognitive control tasks: A review (2018, methodology): “For a comprehensive review of older studies on the topic of pupil dilation and cognition, the reader is referred to earlier work (Beatty & Lucero-Wagoner, 2000; Just et al., 2003).”
Pupil size variations correlate with physical effort perception (2014, background): “Indeed, during mental effort, an increase in pupil diameter has been consistently observed in a very wide variety of tasks (as reviewed in Just et al., 2003), and this increase correlates with the difficulty of the task at hand.”
Beyond eye gaze: What else can eyetracking reveal about cognition and cognitive development? (2016, background): “A more recent comutational framework has proposed that pupil dilation reflects apacity utilization, the balance between task demands and indiidual cognitive resources (Just et al., 2003).”
Eye tracking studies of normative and atypical development (2007, unknown): “Phasic pupillary dilations increase with task difficulty in many other tasks (Beatty, 1982; Beatty & Lucero-Wagoner, 2000; Brown et al., 1999; Granholm, Chock, & Morris, 1998, 2000; Just et al., 2003; Minassian, Granholm, Verney, & Perry, 2004; Nuthmann & van der Meer, 2005; Schlemmer, Kulke, Kuchin”
Understanding changes in mental workload during execution of goal-directed tasks and its application for interruption management (2008, unknown): “Research has shown that pupil dilation is a reliable and valid indicator of mental workload [Beatty 1982; Just et al. 2003; Pomplun and Sunkara 2003; Verney et al. 2004].”
