You Still Need Your Brain - 0 views

Lara Cowell on 19 Jun 17Daniel T. Willingham, a professor of psychology at the University of Virginia, notes that while Google is good at finding information, the brain beats it in two essential ways. 1. Context: Champions of Google underestimate how much the meaning of words and sentences changes with context. With the right knowledge in memory, your brain deftly puts words in context. 2. Speed Quick access is supposed to be a great advantage of using the internet. Students have always been able to look up the quadratic equation rather than memorize it, but opening a new browser tab takes moments, not the minutes required to locate the right page in the right book. Yet "moments" is still much slower than the brain operates. That's why the National Mathematics Advisory Panel listed "quick and effortless recall of facts" as one essential of math education. Speed matters for reading, too. Researchers report that readers need to know at least 95 percent of the words in a text for comfortable absorption. Pausing to find a word definition is disruptive. Good readers have reliable, speedy connections among the brain representations of spelling, sound and meaning. Speed matters because it allows other important work - for example, puzzling out the meaning of phrases - to proceed. Using knowledge in the head is also self-sustaining, whereas using knowledge from the internet is not. Every time you retrieve information from memory, it becomes a bit easier to find it the next time.
