Improvements in performance on visual tasks due to practice are often specific to a retinal position or stimulus feature. Many researchers suggest that specific perceptual learning alters selective ...

A critical step in visual perceptual processing is integrating local visual elements into contours so that shapes can be derived from them. It is often assumed that contour integration may reflect ...

PROVIDENCE, R.I. [Brown University] -- Past studies have found that rewarding participants during a visual perceptual task leads to performance gains. However, new research suggests that these ...

Which sleep stage is most important for learning: REM or non-REM? Does sleep improve learning by enhancing skills while people snooze, or by cementing those skills in the brain so that they're less ...

A neuroscientist offers a new framework to explain how the brain makes predictions. He outlines how “prediction” may be a general principle of cortical function—along with the already-established role ...
