No two people age the same way. Some become stereotypically absent-minded while others remain just as cognitively sharp as their younger counterparts. Shaping these differences in behavior is a complicated interplay between genes and lifestyle. A growing body of research is teasing out the relative roles of genetics and lifestyle factors in cognition in old […]
I recently found myself in a touch tunnel at a science museum. Basically in pitch darkness in a box, I had to feel my way through a maze of turns. As I did so, I found myself often thinking about my arms’ position relative to not just the tunnel but to each other and the rest of […]
A simple trip to the grocery store can be an exercise in trying to keep your attention focused on a task. You may have a list of items you need to buy but have a constant barrage of sale signs and displays enticing you to reward yourself. How do these incentives affect our attention? A […]
Picking a new dentist or doctor can be harrowing experience. Internet reviews and word of mouth may help, but oftentimes it comes down to first impressions, maybe even just a photo online. A new study shows that these impressions of people’s competence actually affect our anticipation of pain. “The goal of this study was to […]
When babies are born, they undergo a hearing test with a simple little machine. What if one day that test could also predict how well a child will be able to read and identify those children early may need extra help? A new study has taken a crucial first step toward that possibility. In PLOS […]
Pixar’s Inside Out portrays memories as glowing individual spheres that we replay in our minds like a movie on a projector screen. But in real life, neuroscientists have found that memories are not compartmentalized into perfect little bubbles; they are represented over a largely distributed set of brain regions. And the same brain regions at […]
Often thought of in pop culture as a funny quirk (think: Cameron Diaz singing karaoke in My Best Friend’s Wedding), tone deafness is actually a brain disorder. Whereas most of us derive great pleasure from music, someone who is tone deaf may hear music as a noisy din and may even avoid situations where music […]
It’s a hot summer day and you are crammed onto a commuter train. So you may take measures to cope with the uncomfortable closeness of strangers: Perhaps you put in earbuds or read a book, or perhaps you just avoid eye contact and turn away. All of these actions change how we focus our attention […]
We all predict the future every time we listen to someone speak or read a book. If I say “barbed,” for example, what word comes next? How about “undivided”? (see answers below, along with other top word pairings) The ability to predict words helps us take mental shortcuts in language. And a new study finds […]
For one person, chocolate smells pinky and stripy, for another it was a hazy mist. These were not smell associations – the images are how some people actually experience the smell of chocolate. The people drawing the images have a rare form of synesthesia, in which a smell elicits a color. And in a new […]
