The composition of young children's vocabularies in 7 contrasting linguistic communities was investigated. Mothers of 269 twenty-month-olds in Argentina, Belgium, France, Israel, Italy, the Republic of Korea, and the United States completed comparable vocabulary checklists for their children. In each language and vocabulary size grouping (except for children just learning to talk), children's vocabularies contained relatively greater proportions of nouns than other word classes. Each word class was consistently positively correlated with every other class in each language and for children with smaller and larger vocabularies. Noun prevalence in the vocabularies of young children and the merits of several theories that may account for this pattern are discussed.

This study investigated and compared ideas about parenting in Argentine, Belgian, French, Israeli, Italian, Japanese, and U.S. mothers of 20-month-olds. Mothers evaluated their competence, satisfaction, investment, and role balance in parenting and rated attributions of successes and failures in 7 parenting tasks to their own ability, effort, or mood, to difficulty of the task, or to child behavior. Few cross-cultural similarities emerged; rather, systematic culture effects for both self-evaluations and attributions were common, such as varying degrees of competence and satisfaction in parenting, and these effects are interpreted in terms of specific cultural proclivities and emphases. Child gender was not an influential factor. Parents' self-evaluations and attributions help to explain how and why parents parent and provide further insight into the broader cultural contexts of children's development.

Maternal speech to infants of 2 ages in 4 cultures was examined to probe how infant age and cultural variation influence the contents of that speech. Argentine, French, Japanese, and U.S. American mothers were individually videotaped in naturalistic free-play interactions at home with their 5-and 13-month-old infants, maternal speech was transcribed, and the contents classified as affect salient or information salient. Mothers in the 4 cultures use all speech categories to young infants, speak to older infants more than to younger infants, but differ in the emphasis of their speech. Similarities speak to the universality of maternal speech to infants, provoked perhaps by infants' common psychological status; differences in the speech mothers choose to emphasize speak perhaps to the expression of cultural preferences. Maternal speech to infants serves several significant functions in development. First, verbal interactions establish ties of

This study examines and compares prominent characteristics of maternal responsiveness to infant activity during home-based naturalistic interactions of mother-infant dyads in New York City, Paris, and Tokyo. Both culture-general and culture-specific patterns of responsiveness emerged. For example, in all 3 locales infants behaved similarly, mothers also behaved similarly with respect to a hierarchy of response types, and mothers and infants manifest both specificity and mutual appropriateness in their interactions: Mothers responded to infants' exploration of the environment with encouragement to the environment, to infants' vocalizing nondistress with imitation, and to infants' vocalizing distress with nurturance. Differences in maternal responsiveness among cultures occurred to infant looking rather than to infant vocalizing and in mothers' emphasizing dyadic versus extradyadic loci of interaction. Universals of maternal responsiveness, potential sources of cultural variation, and implications of similarities and differences in responsiveness for child development in different cultural contexts are discussed.
