The Development of Memory in Infants
Memory is not a single entity but a patchwork of several different forms of information storage that emerge progressively with the maturation of different brain circuits. Babies begin life with a primitive yet very useful set of memory skills; lower parts of the brain can store information, but it is at an automatic level, beneath consciousness, and lasts for relatively short periods of time. Then, starting at eight or nine months of age, they show signs of a more flexible, deliberate type of...Folksonomies: memory infant development

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... 1 notes
