Creative Space

A Cornell experiment in the 1960s polled a group of computer science students and divded them into those who liked to work with music in the background and those who didn't. They put 1/2 of each group together in a silent room, and the other 1/2 in a different room equipped with headphones and a musical selection. To no one's surprise, they performed about the same in speed and accuracy of completing a Fortran programming task. The part of the brain required for arithmetic and related logic i...

 Hyperacuity and Obligatory Looking

Beginning about four months of age, the perception of detail takes another leap forward with the emergence of hyperacuity: the ability to discriminate features that are up to ten times finer than the size of the photoreceptors should theoretically permit. It is this ultrafine discrimination that allows us, for instance, to see a very slight glitch in an otherwise straight line. even though the size of the glitch is below our eyes' limit of resolution. It is not yet known how our brains perfor...
