A quick eye-exercise can improve your performance on memory tests (but only if you're right-handed) - http://scienceblogs.com/cogniti...
"Several studies have confirmed this bizarre proposition: If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start. Really." - Casey Muller
Did they control it against stuff like closing your eyes for 30 seconds, I wonder? - Robin Barooah
I buy this. Moving your eyes from side to side activates both brain hemispheres. Left-handed people get plenty of left brain stimulation anyway. Right-handed people may not get plenty of right-brain stimulation. I'd be interested in seeing the breakdown by gender. - Daniel Dulitz
I wonder how wide the error bars are on the graphs, and what confounding factors have been controlled for in the samples. The second graph seems to indicate that, without eye movement, strongly right-handed people have more than three times the false alarm rate as non-strongly right-handed people. - Simon
Dang - I'm a strong lefty. Won't help. - Hutch Carpenter
