Clutter is a fact of life. Wherever you look, there is clutter. Even the tidiest of tidy rooms will contain much visual clutter: some objects will be in front of others, thereby partially obscuring them. So if you need to reach for the cup that’s behind the toaster, then your visual system must work through […]

Finding your office key amidst your building key, the lab key, your house key, the other house key in case you need to cat-sit for a friend is like finding a needle in a haystack. People who have tons of keys develop elaborate organizational systems, clumping together keys for similar places―like the Psychology building―which can […]
You reach for the life-saving glass of water handed to you from the judge’s bench, with a bit of assistance from your co-defendant. You take a sip and the rest is movie history.
