Shadow,
back in my day we had large buildings at our Uni called
libraries.
These buildings were full of books and journals which were published to disseminate the writings of learned (and sometimes, not-so-learned) people who did experiments and such.
I am sure you are all over it but please tell me that 'research' at University these days does not consist of participating in a thread on an anonymous forum???
I am pretty sure your library access will include heaps of Aviation psych journals covering exactly this topic. You will probably find that there is online access through your Uni library to these journals, too.
No substitute for doing the legwork yourself
