This study evaluated the receptive vocabulary ability and nonverbal cognitive ability of 20 monolingual (Spanish-speaking) and 1 1 bilingual (Spanish/English-speaking) Mexican-American preschool children, ages 45 to 65 months. The children obtained significantly lower scores on the Peabody Picture Vocabulary Test-Revised (PPVT-R) than on the Perceptual Performance Scale of the McCarthy Scales of Children's Abilities. On both measures, the bilingual group obtained significantly higher scores than did the monolingual group. The results support prior recommendations that the PPVT-R not be used to estimate the intelligence level of Hispanic children.
