the whole thing is: in her preliminary study, people with more male-hormones (layman term) identify depth by shapes in motion. people with less (or female-hormones, again, very layman terms) get sick when there is no light hinting on that 3d body movement.

You don't even need an oculus to test the hypothesis. it can probably be tested by:

- showing that spinning woman shadow that everyone sees spinning to a different direction, see if women get sick/annoyed/react in any manner faster than men. or;

- put lots of people in a room with a hanging light as the only light source, kick that light in a large pendulum movement. check if the women get sick faster than the men.

I used to work for a company that did simulated driving tests. When looking at the class reviews, more women than men would complain of SAS (simulator adjustment syndrome). I can also say that I get the same problem if I play video games too long or if the lighting is wrong (game and/or room). I know it's anecdotal, but after reading hundreds of class reviews it's interesting to see some science behind it.

I'm no scientist, but off the top of my head, I'd say you would start by finding a group of women who experience simulator sickness with the Rift, and a given simulation, at a significantly higher rate than do men. Then you'd want to modify the simulation, e.g. by adding normal mapping to offer the shading cues boyd discusses, and see whether and how the incidence of simulator sickness changes.
