  abstract = {Both adults and infants are faster at discriminating between two colors
	from different categories than two colors from the same category,
	even when between- and within-category chromatic separation sizes
	are equated. For adults, this categorical perception (CP) is lateralized;
	the category effect is stronger for the right visual field (RVF)-left
	hemisphere (LH) than the left visual field (LVF)-right hemisphere
	(RH). Converging evidence suggests that the LH bias in color CP in
	adults is caused by the influence of lexical color codes in the LH.
	The current study investigates whether prelinguistic color CP is
	also lateralized to the LH by testing 4- to 6-month-old infants.
	A colored target was shown on a differently colored background, and
	time to initiate an eye movement to the target was measured. Target
	background pairs were either from the same or different categories,
	but with equal target-background chromatic separations. Infants were
	faster at initiating an eye movement to targets on different-category
	than same-category backgrounds, but only for targets in the LVF-RH.
	In contrast, adults showed a greater category effect when targets
	were presented to the RVF-LH. These results suggest that whereas
	color CP is stronger in the LH than RH in adults, prelinguistic CP
	in infants is lateralized to the RH. The findings suggest that language-driven
	CP in adults may not build on prelinguistic CP, but that language
	instead imposes its categories on a LH that is not categorically
	prepartitioned.},
