How can our brains decipher even garbled nonsense?

A key factor could be context.

 

How cn yuor brian rd ths? Apparently, context is key!

 

You might not realize it, but your brain is a code-cracking machine.

NEWS: Window Installed Into a Live Brain

 

Passages like these have been bouncing around the Internet for years. But how do we read them? And what do our incredibly low standards for what's legible say about the way our brains work?

According to Marta Kutas, a cognitive neuroscientist and the director of the Center for Research in Language at the University of California, San Diego, the short answer is that no one knows why we're so good at reading garbled nonsense. But they've got strong suspicions.

"My guess is that context is very, very, very important," Kutas told Life's Little Mysteries.

We use context to pre-activate the areas of our brains that correspond to what we expect next, she explained. For example, brain scans reveal that if we hear a sound that leads us to strongly suspect another sound is on the way, the brain acts as if we're already hearing the second sound. Similarly, if we see a certain collection of letters or words, our brains jump to conclusions about what comes next. "We use context to help us perceive," Kutas said.

It's not a perfect system, however. In the above passages, Kutas suspects that you probably didn't get every single word right just from knowing what came before it. You only thought you were reading the passage perfectly, because you automatically (and subconsciously) went back and filled in any gaps in your knowledge based on subsequent context — the words that came later.

Additionally, in the case of the first example (the words with jumbled middle letters), it helps that your brain processes all the letters of a word at once, rather than one at a time. Thus, the letters "serve as contexts for each other," Kutas said.
