Yes.  This has been a topic of interest for decades.  You should be
able to find references easily by doing a literature search.  You're
at a university; go to your research library and find a librarian who
can help you.  If you have access to STAR and IAA, look in category 8.
Workload is a standard keyword.

We've done a lot of work in handling qualities on this, usually with
adding extraneous tasks (repeating numbers, punching buttons when
lights come on, and so on).  Obviously, any measurement is going to be
a second-order measurement.  I'd suggest a search through the
proceedings of the AIAA Guidance, Navigation, and Control and
Atmospheric Flight Mechanics conference proceedings for papers on the
topic.  You might also contact Calspan, STI, AFWAL, and NASA Ames
Research Center.

On the X-15 we measured heart rate and, maybe, GSR.  I believe the US
Navy also measured heart rate.
