When we are trying to understand what someone is saying, we rely a lot on the movement of their face. We pay attention to how their faces move, and that informs our understanding of what is said. The classic example of this is the McGurk effect, where the same sound accompanied by different facial movements…

We can recognize the faces of our friends very quickly from just a snapshot. Within 150 milliseconds of being flashed a photo, brain signals respond differently to photos containing animals than photos with no animals. We can categorize scenes as “beach,” “forest,” or “city” when they are flashed for even shorter periods. But we also…

Take a look at this movie (QuickTime Required): The moving object is exactly the same in each picture, but the background is different. If you’re like most people, you’ll see one object as an ice skater, and the other as a spinning top. This puts the objects in two different classes — animate (something that…

This is a guest post by David Kerns, one of Greta’s top student writers for Spring 2007. As movie special effects technology improves, more and more live-action shots are being replaced with computer animation. Harry Potter flies across the Quidditch field; Spider-Man swings from web to web through the cityscape of New York City, and…

When Greta earned her Ph.D. 13 years ago, Jim was two and a half years old, and Nora was just 10 months old. Jim knew a few words, and Nora couldn’t talk at all. You might think a baby as young as Nora wouldn’t have an appreciation for music or dance. If you can’t walk,…

The pain can be so excruciating that even “passive” activities like sitting up to read a book become intolerable. Whether you work in…

There is a considerable body of research showing that eye contact is a key component of social interaction. Not only are people more aroused when they are looked at directly, but if you consistently look at the person you speak to, you will have much more social influence over that person than you would if…

When we see a familiar face, or even a photo of a favorite car or pet, we’re often flooded with memories from our past. Sometimes just seeing a person or object that’s similar to the ones in our memory will trigger recollections we never knew we had. Maybe you’ve had a memory triggered by a…

Many many studies have repeatedly shown the dangers of driving while using a cell phone. Yesterday, while discussing a new law in Britain imposing heavy penalties not only for driving using a handheld phone, but also while using phones with hands-free kits, commenter Jan claimed that talking to a passenger was less dangerous than talking…

Here in North Carolina, for many sports fans, it’s considered common knowledge that basketball referees don’t call fouls against Duke. The reasons for the supposed bias vary from racism, to payoffs from wealthy alums, to the intimidating atmosphere at Duke’s legendary Cameron Indoor Stadium, but nearly everyone in the state who’s not a Duke fan…
