Jeff Raskin's book (The Humane Interface) lists a bunch of scientific results, so does "Designing with the Mind in Mind" and "97 things every designer needs to know about people".
I'm copy-pasting the reference list of my own Software Ergonomy class back from Uni, it's an academic website, so perhaps some of them could be academical:

Otherwise, when I was researching UX in British Library (bl.uk), there were some other journals about interface design, human-computer interaction desing as well. Look around here (this is the exact interface which you have inside BL as well):

Eg. this is a list of journals about ergonomics, some of them HCI (Human-Computer Interaction)
