How Alonzo Clemons Overcame A Brain Injury To Become A World-Class Sculptor
4 of 50
You've probably dabbled with Play-Doh as a kid. Most people's sculpting experience ends around there, but that wasn't the case for Alonzo Clemons. Severely disabled as a young child, Clemons could barely speak, nor could he feed himself or tie his own shoes. But his disability brought on one important gift—acquired savant syndrome, a condition where high-level, often prodigious skills appear after a brain injury. This gave Clemons an uncanny ability to create hyper-accurate sculptures of animals that started from a young age and only sharpened as he grew up. Today, he can simply glance at a horse on TV and, in just 20 minutes, sculpt a clay figure of that horse that is anatomically correct down to every muscle. Despite his still very limited vocabulary, Clemons has shown his work throughout the world. Hear Clemons speak about his work in the video below.
Recalling A Word On The Tip Of Your Tongue Helps Ensure You'll Forget It Next Time
5 of 50
Have you ever noticed that there are some words you can never remember? According to research out of McMaster University, it's not the words, but the struggle to remember that's to blame. Scientists gave 30 students definitions of words and asked the students to say whether they knew the word, didn't know the word, or it was on the tip of their tongue (what psychologists call a TOT, or tip-of-the-tongue state). If they were in a TOT, researchers randomly assigned them to spend either 10 or 30 seconds trying to remember the word before finally seeing what it was. Two days later, the students were tested on the same words again. Surprisingly, instead of more easily recalling the words they had been shown after their TOT state, those words tended to be on the tips of the students tongues just like they were before. This was even more likely for the students who had spent more time trying to recall them.
