Abstract
Three cultural comparisons address specificities and commonalities in the acculturation of infant behaviors and maternal parenting practices. Immigrant Japanese, Korean, and South American families were compared to nonmigrant families in their respective cultures of origin (Japan, South Korea, and South America) and their single common culture of destination (United States). Altogether, 13 infant behaviors and 15 maternal parenting practices in 408 5½-month-old infants and their mothers were examined. About half of infants' and half of mothers' behaviors showed specificity and half commonality in group-level acculturation comparisons. Immigrant infants differed from infants in their cultures of origin and destination with respect to emotional expression, vocalization, and physical development. Immigrant mothers differed from mothers in their cultures of origin and destination in speech to their infants, permitted sounds in the environment, and encouraging infants' physical development. Implications of specificity and commonality in acculturation of infant and mother behaviors across groups are discussed.
