The brain seeks meaning and patterns. It would be very adaptive to do so in nature, because you need to know how to predict danger and to develop social ties. So our brains are very good at recognizing patterns, but also at creating them, even when they're not there. - Dr. Jay Giedd, Chair of Child Psychiatry at Rady Children's Hospital - San Diego…

Studies show that, especially for young children, if you prematurely wake them up and deprive them of that much needed sleep, it becomes detrimental to their proper cognitive development further down in life. I just wonder about the amount of damage we're doing to kids with 7:20 AM school start times. - Ilian Daskalov, senior undergraduate student …

Global Workspace Theory is probably oversimplified, just like the Newtonian theory of the planets and their orbits. And that's what framework theories usually do. You don't want to go to them for the details, you want to go to them for the overview. And Global Workspace is really an overview. – Dr. Bernard Baars, originator of Global Workspace Theo…

"I think in terms of consciousness, it seems to me that these Feelings of Knowing are perhaps the conscious tip of the iceberg for this huge amount of unconscious processing that's going on of all this information in our environment, where maybe I couldn't tell you why I know there's danger, but I know." - Alea Skwara, PhD Candidate in the Percepti…

"One of the major features of the Global Workspace hypothesis began with limited capacity, that there has to be a compensatory event in the brain happening, and the most plausible one, for various reasons, including other people's work, of course, was that there's some kind of very wide recruitment of brain resources that happens as a function of b…
