I recently spotted a paper (pdf) in the July 2008 issue of the influential journal Psychological Science with the following title: "Objects on a Collision Path With the Observer Demand Attention."
Hey, you think I should pay attention to that thing headed for my face? Leave it to scientists to require grant funding to figure out what they were supposed to pick up in gym class by like first grade.
Seriously, those guys would not stand at chance at Mentalball.
(Super-seriously, there are some new findings in the paper. Don't let the cool kids tell you science is not cool.)
