Responsiveness in mother-infant social interactions among immigrant and nonmigrant families: Japanese, South Korean, South American, and European American.

A culture learning perspective motivated the present study of the acculturation of responsiveness in mother-infant interactions. Several conceptual and analytic features of responsiveness in mother-infant social interactions were examined: Temporal contingency, mean differences in responsiveness among and within dyads, attunement of mother and infant responsiveness withing dyads, and the influence of acculturation on individual responsiveness. Methodologically, acculturation was assessed at group and individual levels in immigrant Japanese, South Korean, and South American dyads in comparison with nonmigrant dyads in their respective cultures of origin (Japan, South Korea, and South America) and their single common culture of destination (United States). In total, 408 mothers and their 5½-month-old infants were observed in the naturalistic setting of the home, and observations were coded for mothers' speech to infant, social play, and encouraging her infant to look at her, and infants' looking at mother and nondistress vocalizations. Odds ratios were then generated for mother and infant responsiveness in four types of social interactions: Mother speaks to infant and infant looks at mother (Mother Speak/Infant Attend), mother plays with infant and infant looks at mother (Mother Play/Infant Attend), mother plays with infant and infant vocalizes (Mother Play/Infant Vocalize), and mother encourages infant to look at her and infant vocalizes (Mother Encourage/Infant Vocalize). Five key findings emerged. Specifically, mother and infant responsiveness in Mother Speak/Infant Attend interactions were temporally contingent in all cultures. Mean differences in responsiveness among cultures emerged, and within dyads infants were more responsive than their mothers in Mother Speak/Infant Attend interactions. Mother and infant responsiveness in Mother Speak/Infant Attend interactions were attuned in all cultures. Responsiveness in Mother Play/Infant Vocalize interactions showed acculturation effects at the individual level. Implications of these findings for understanding the development of responsiveness in social interactions and acculturation in immigrant families are discussed.
