How Big Is That Goalpost?

An interesting article in Wired about perception says that your perception of an obstacle to performance -- the width of a goal post, for example, or the length of a circuit on a track -- may be affected by your prior performance in the task. The more often you make the kick successfully, the wider the posts appear; the more you miss, the narrower. So when a batter says, after striking out, that the pitcher's throwing aspirins, that may be exactly how it looks to him. Intruiging.
