Euclidian Orientation vs. Left/Right Landmark
In other science news, I really enjoyed reading this article positing "Never Ask A Gay Man For Directions." The writing style rose well above the usual dry-as-matzo, just-the-facts-ma'am style that usually characterizes science news and moved right on into amusing. The long and the short of it is that there are statistically significant differences in the neural makeup between heterosexual and homosexual brains, but your mileage may vary. Also, lesbians seem to get the short shrift because they (statistically speaking) don't get the verbal skills a woman gets, but also don't get the upsides that hetero males get. Too bad for them.
