At the Society for Neuroscience annual meeting in San Diego Nov. 10, 2013, Brown University scientists presented research showing what happens in the brain during sleep to lock in learning of a visually oriented “Where’s Waldo”-like task.

PROVIDENCE, R.I. [Brown University] — As any indignant teacher would scold, students must be awake to learn. But what science is showing with increasing sophistication is how the brain uses sleep for learning as well. At the annual meeting of the Society for Neuroscience in San Diego Nov. 10, 2013, Brown University researchers discussed new research describing the neural mechanism by which the sleeping brain locks in learning of a visual task.

Training Improves Recognition of Rapid-Fire Objects

“Attentional blink” is the term psychologists use to describe our inability to recognize a second important object if we see it less than half a second after a first one. It always seemed impossible to overcome, but in a new paper in the Proceedings of the National Academy of Sciences, Brown University psychologists report they’ve found a way.

PROVIDENCE, R.I. [Brown University] — So far it has seemed an irreparable limitation of human perception that we strain to perceive things in the very rapid succession of, say, less than half a second. Psychologists call this deficit “attentional blink.” We’ll notice that first car spinning out in our path, but maybe not register the one immediately beyond it. It turns out, we can learn to do better after all. In a new study researchers now based at Brown University overcame the blink with just a little bit of training that was never been tried before.
