ABSTRACT: Tested visual search asymmetries in 3- and 4-mo old infants indicative of a preattentive phase. 32 infants from
 each age group were presented with 2 visual arrays to the left and right of midline. The stimuli used in the visual search task
 were constructed of feature-positive (FP) and feature-absent (FA) arrays, each paired with a corresponding homogeneous
 array in which no discrepant element was embedded. Visual fixations of infants were measured. Results show a "pop-out"
 effect for FP stimuli in both age groups, similar to, but not as strong as, that described by A. Treisman and J. Souther (1985)
 for adults. This may reflect limitations of infant visual search, the methodology used to assess it, or the difference in the size of
 the effect between adults and infants. ((c) 1997 APA/PsycINFO, all rights reserved)
