Sounds interesting, though the IRB has to be involved given the possibility of accidents. There is research on perception of chimeric faces that may be relevant, as in
http://www.jneurosci.org/content/23/9/3820.full.pdf I did a quick little study of such faces with an undergraduate for an undergraduate conference years ago. In general, you find better recognition/impact of emotional expressions in the left visual field, and I do this sometimes as a class demo, having students choose the happier face - one with the smile on the poser's left side vs. the smile on the right. In a classroom it is a robust effect despite the fact that the corpus callosum is intact and the students are free to move their head and eyes at will. The literature on this gets a little complex though as there are also L/R differences (in the real world) between the facial expressions we send from the face. I am wondering how far you can go with this by just having people keep their head stationary while a variety of images/stimuli are presented ... John K ========================== John W.

Hello, TIPSters -- So, today in cognitive we were talking about linguistic capacity and split brain and all that sort of stuff, and one student wondered whether or not she'd be able to blacken half of her contact lenses, say, on the right sides (she's astigmatic and has weighted lenses) and wander around with only her right hemisphere making (initial, pre-callosal) contact with the world. I'm skeptical that she'd notice much, given the size of the connection between the hemispheres, but did promise that I'd try to find out if anyone had ever done such a thing, and if so, what would be a good way to blacken a contact lens that wouldn't also risk eye damage (we discussed and immediately rejected Sharpies). Anyone have thoughts on this?
