Complete video at: http://fora.tv/conference/ideas_economy_information Nicholas Carr, author of The Shallows: What the Internet Is Doing to Our Brains, explains why the human brain struggles to process information that is presented "with the intensity and the quantity and the speed we find ourselves surrounded by today." Revising the 1956 psychology paper, "The Magical Number Seven," Carr explains that our working memory - everything comprising the consciousness at a given moment - can only hold between two and four items at a time. ----- The Ideas Economy: Information is a fresh look at knowledge management for the information age. The Economist will bring together theorists, strategists, and innovators who understand how to harness data to create value and advance individual, corporate, and social good.

However, a new study shows that there is actually one way that the human brain can multitask. Join Trace as he breaks down how this new finding sheds light on our extremely limited ability to multitask.

Why can't we recall being born? It was kind of a big day, so you'd think we'd remember. Anthony looks at how the inner workings of a baby's brain differs from that of a full grown adult.

Why Can't You Remember Being a Baby? http://mentalfloss.com/article/12330/why-cant-you-remember-being-baby "There are probably blackout periods you can't remember at all from your childhood, and the memories you do have are likely hazy and garbled." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!
