Possibly a holy grail for CTML and CTL researchers in the near future will be the quest to find evidence of three separate cognitive load processes (essential, extraneous, generative) and how to measure them reliably (Brünken, Plass, & Leutner, 2003; Antonenko, Paas, Grabner, and van Gog, 2010). A recent study by Antonenko & Niederhauser (2010) found that measuring overall cognitive load with self-reports may not be adequate. Instead, they suggest that cognitive load should be viewed as a dynamic process and assessed with EEG-based measures to provide a more complete picture for explaining the causes and effects of cognitive load.
