Abstract
Four‐ to 10‐month‐old infants process different information within geometrical patterns with each of the 2 hemispheres (Deruelle & de Schonen 1991,1995). This study was designed to test whether this early difference between the hemispheres’ modes of processing also holds in the case of face processing. Four‐ to 10‐month‐old participants had to discriminate and recognize with each hemi‐visual field the 2 members of a pair of faces. There were 3 pairs of faces that differed by either eye shape, eye size, or eye orientation. The results confirmed the predictions made on the basis of adult studies and infants’ hemispheric differences in geometrical pattern processing: A left hemisphere advantage was observed in the case of the 1st pair of faces and a right hemisphere advantage with the 2nd and 3rd pairs. It is suggested that the early right hemisphere advantage over the left observed by de Schonen and Mathivet (1990) in face recognition by 4‐ to 9‐month‐old infants may be mainly based on the difference in the kind of visuospatial information processed by each hemisphere.
