Distortion Of Time Perception Offset By Sense Of Control
2012-10-25 09:28:13

Jedidiah Becker for redOrbit.com — Your Universe Online There are few more fascinating and mind-bending frontiers in fields of neuroscience and psychology than the study of how the brain perceives time. While symphonies, stock markets and our daily schedules are conveniently constructed around the well-defined, predictable progression of what might be called 'objective time', our brains take a much more flexible approach to dealing with passing events, stretching, condensing and...

Visual Awareness Improved Through Rhythmic Oscillations In Brain
2012-08-29 15:40:58

redOrbit Staff & Wire Reports - Your Universe Online Rhythmic oscillations in the brain provide heightened visual awareness that, when controlled, could help improve visual processing in critical environments such as air traffic control towers and nuclear power plants, according to a new study by the Beckman Institute. Using periodic visual stimuli and electroencephalogram (EEG) recordings, the researchers found they could precisely time the brain´s natural oscillations to...

A new study in the journal Cognition overturns a decades-old theory about the nature of attention and demonstrates that even brief diversions from a task can dramatically improve one's ability to focus on that task for prolonged periods.The study zeroes in on a phenomenon known to anyone who's ever had trouble doing the same task for a long time: After a while, you begin to lose your focus and your performance on the task declines.Some researchers believe that this "vigilance decrement," as...

U.S. researchers say they've determined the brain can use bodily cues to help understand and solve complex problems. University of Illinois Professor Alejandro Lleras, who led the study with Vanderbilt University postdoctoral researcher Laura Thomas, said the research is the first to show a person's ability to solve a problem can be influenced by body movements. Our manipulation is changing the way people think, said Lleras. In other words, by directing the way people move their bodies, we...
