We rarely listen to just one stream of information at a time. Whether we are at a dinner party, on a crowded bus, or talking on the phone while walking down a busy street, more often than not there are multiple voices that compete for our attention. People are generally very good at focusing on […]

Certain songs have a way of getting into your head and staying there for a while. We’ve covered the cognitive side of earworms before. These songs that haunt us tend to have a recognizable tempo or beat—usually one that we can move to. Lady Gaga has given us a number of earworms, including Poker Face, […]
As we go about our daily lives, we are constantly exposed to new information―news reports from a foreign country, politicians’ statements about domestic policy, a friend’s description of a new restaurant, and celebrity gossip. Some of that information is true and some is false. How do we remember which statements are true and which are […]
Noise can be annoying. It is also by far the most common preventable cause of hearing impairment. Unsurprisingly, noise levels in the workplace are therefore subject to occupational health regulations. Workers must wear headphones to protect themselves against noise from chainsaws, jet engines, or any other loud device. No such standards exist for recreational noise, […]
Clutter is a fact of life. Wherever you look, there is clutter.

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 […]
Put Tom Cruise and Dustin Hoffman together and you get Rain Man, the Academy-Award winning story of an autistic savant—played by Hoffman who received the Best Actor award for his performance—who turns out to have many unexpected talents. The clip below shows one famous scene, in which Hoffman knows within seconds that the waitress dropped […]
Have you ever met anyone who dislikes magic tricks? No, me neither. Magicians and magic tricks seem to be universally appreciated in western culture. Whether it is at corporate events, kids’ birthday parties, or simply at the pub down the road, magic is fun and attracts an appreciative audience of all ages. One question that […]
It is rare that we can do two things at once—if someone asks you to rub your stomach and pat your head, odds are that you’ll rub your head. A better strategy for a lot of different cognitive tasks is to switch between them. Switching typically comes at a cost, however. Switching can even negatively […]
