Hemispheric differences in face processing and brain maturation

(from the chapter) [reviews studies which] demonstrate that the right hemisphere plays an important role in the processing of individual faces early in life / face processing between the age of 4 and 9 mo seems to be linked to configural processing / the right hemisphere processes the configural aspects of patterns and faces, while the left hemisphere processes local aspects / this difference between the ways in which the two hemispheres represent the visual world is present at an age when no transfer of this information once acquired is possible from one hemisphere to the other / conjecture . . . that a difference between the maturation rates of some portions of the right and left hemispheres may be one possible factor contributing to the functional differences observed / preliminary results of a PET [positron emission tomography] scan study performed on 2-mo old infants are [presented] (PsycINFO Database Record (c) 2005 APA, all rights reserved)
