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.

Synchrony in mother-infant vocal interactions revealed through timed event sequences

This report extends a previous cross-cultural study of synchrony in mother-infant vocal interactions (Bornstein et al., 2015) to immigrant samples. Immigrant dyads from three cultures of origin (Japan, South Korea, South America) living in the same culture of destination (the United States) were compared to nonmigrant dyads in those same cultures of origin and to nonmigrant European American dyads living in the same culture of destination (the United States). This article highlights an underutilized analysis to assess synchrony in mother-infant interaction and extends cross-cultural research on mother-infant vocal interaction. Timing of onsets and offsets of maternal speech to infants and infant nondistress vocalizations were coded separately from 50-min recorded naturalistic observations of mothers and infants. Odds ratios were computed to analyze synchrony in mother-infant vocal interactions. Synchrony was analyzed in three ways -- contingency of timed event sequences, mean differences in contingency by acculturation level and within dyads, and coordination of responsiveness within dyads. Immigrant mothers were contingently responsive to their infants' vocalizations, but only Korean immigrant infants were contingently responsive to their mothers' vocalizations. For the Japanese and South American comparisons, immigrant mothers were more contingently responsive than their infants (but not robustly so for South American immigrants). For the Korean comparison, mean differences in contingent responsiveness were found among acculturation groups (culture of origin, immigrant, culture of destination), but not between mothers and infants. Immigrant dyads' mean levels of responsiveness did not differ. Immigrant mothers' and infants' levels of responsiveness were coordinated. Strengths and flexibility of the timed event sequential analytic approach to assessing synchrony in mother-infant interactions are discussed, particularly for culturally diverse samples.

Neurobiology of culturally common maternal responses to infant cry

This report coordinates assessments of five types of behavioral responses in new mothers to their own infants' cries with neurobiological responses in new mothers to their own infants' cries and in experienced mothers and inexperienced nonmothers to infant cries and other emotional and control sounds. We found that 684 new primipara mothers in 11 countries (Argentina, Belgium, Brazil, Cameroon, France, Kenya, Israel, Italy, Japan, South Korea, and the United States) preferentially responded to their infants' vocalizing distress by picking up and holding and by talking to their infants, as opposed to displaying affection, distracting, or nurturing. Complementary functional magnetic resonance imaging (fMRI) analyses of brain responses to their own infants' cries in 43 new primipara US mothers revealed enhanced activity in concordant brain territories linked to the intention to move and to speak, to process auditory stimulation, and to caregive [supplementary motor area (SMA), inferior frontal regions, superior temporal regions, midbrain, and striatum]. Further, fMRI brain responses to infant cries in 50 Chinese and Italian mothers replicated, extended, and, through parcellation, refined the results. Brains of inexperienced nonmothers activated differently. Culturally common responses to own infant cry coupled with corresponding fMRI findings to own infant and to generic infant cries identified specific, common, and automatic caregiving reactions in mothers to infant vocal expressions of distress and point to their putative neurobiological bases. Candidate behaviors embedded in the nervous systems of human caregivers lie at the intersection of evolutionary biology and developmental cultural psychology.

Cultural and Parenting Cognitions in Acculturating Cultures

This longitudinal study evaluated cultural differences and developmental continuity and stability in cultural cognitions (acculturation, individualism, collectivism) and parenting cognitions (attributions, self-perceptions, and knowledge) in 86 Japanese American and South American acculturating mothers when their children were 5 and 20 months of age. South American mothers were more collectivistic than Japanese American mothers. Cultural group and attribution differences emerged for mothers' parenting attributions in successful situations, whereas child age and attribution differences emerged for parenting attributions in unsuccessful situations. Japanese American mothers' feelings of competence increased over time. South American mothers were more satisfied in the parenting role than Japanese American mothers. Mothers' knowledge of parenting increased over time in both groups. Mothers' cultural cognitions were stable, as were Japanese American mothers' parenting cognitions. This study provides insight into the differential influence of cultural background on the acculturation of cultural and parenting cognitions in two U.S. acculturating groups.

Cultural and Parenting Cognitions in Acculturating Cultures

This longitudinal study evaluated prediction and coherence in cultural (acculturation, individualism, collectivism) and parenting cognitions (attributions, self-perceptions, knowledge) in 86 Japanese American and South American acculturating mothers. Mothers' cultural cognitions when their infants were 5 months old predicted some parenting cognitions 15 months later, particularly among Japanese American mothers. Coherence among mothers' attributions obtained in both cultural groups when their infants were both 5 and 20 months of age and among Japanese American mothers' self-perceptions of parenting at both time periods. Although a few relations across types of parenting cognitions were found, domains of parenting cognitions were relatively independent. This study provides insight into the nature and structure of cultural and parenting cognitions in two U.S. acculturating groups.

Mother-infant interaction and acculturation: I. Behavioural comparisons in Japanese American and South American families

This study examined similarities and differences in mothers’ and infants’ activities and interactions among 37 Japanese American and 40 South American dyads. Few relations between maternal acculturation level or individualism/collectivism and maternal parenting or infant behaviours emerged in either group. However, group differences were found in mothers’ and infants’ behaviours indicating that culture-of-origin continues to influence parenting behaviour in acculturating groups.

Mother-infant interaction and acculturation: II. Behavioural coherence and correspondence in Japanese American and South American families

This study examined cultural generality and specificity in relations among and between mothers’ and infants’ behaviours in 37 Japanese American and 40 South American acculturating families. Few relations among mothers’ behaviours emerged, except for that between mothers’ social behaviour and other types of maternal behaviour, which appear to reflect the common collectivist orientation of these two cultural groups. Few relations among infants’ behaviours emerged, suggesting that there is independence and plasticity in infant behavioural organisation. Several expected relations between mothers’ and infants’ behaviours emerged, pointing to some universal characteristics in mother-infant interactions.

Child and mother play in cultures of origin, acculturating cultures, and cultures of destination

Immigrant (Japanese and South Americans in the United States) families’ play was compared to play in families in their countries of origin (Japan and Argentina, respectively) and in a common country of destination (European Americans in the United States). Two hundred and forty 20-month-old children and their mothers participated. Generally, the play of immigrant children and mothers was similar to European American children's and mothers’ play. Japanese and Argentine children engaged in more symbolic play, whereas immigrant children engaged in more exploratory play. Likewise, South American immigrant mothers demonstrated and solicited more exploratory play than Argentine mothers. Japanese mothers solicited more symbolic play, and Argentine mothers demonstrated more symbolic play than immigrant mothers. The findings from this study provide insight into the nature of child and mother play generally and that of immigrant children and their mothers specifically and shed light on the parenting climate in which immigrant children are reared.

The Acculturation of Parenting Cognitions: A Comparison of South Korean, Korean Immigrant, and European American Mothers

A three-culture comparison - native South Korean, Korean immigrants to the United States, and native European American mothers - of two types of parenting cognitions - attributions and self-perceptions - was undertaken to explore cultural contributions to parenting cognitions and their adaptability among immigrant mothers. Attributions and self-perceptions of parenting were chosen because they influence parenting behavior and children's development and vary cross-culturally. One hundred seventy-nine mothers of 20-month-old children participated: 73 South Korean, 50 Korean immigrant, and 56 European American. Korean mothers differed from European American mothers on four of the five types of attributions studied and on all four self-perceptions of parenting, and these differences were largely consistent with the distinct cultural values of South Korea and the United States. Generally, Korean immigrant mothers' attributions for parenting more closely resembled those of mothers in the United States, whereas their self-perceptions of parenting more closely resembled those of mothers in South Korea. This study provides insight into similarities and differences in cultural models of parenting, and information about the acculturation of parenting cognitions among immigrants from South Korea.

Mother-Infant Contingent Vocalizations in 11 Countries

Mother-infant vocal interactions serve multiple functions in child development, but it remains unclear whether key features of these interactions are community-common or community-specific. We examined rates, interrelations, and contingencies of vocal interactions in 684 mothers and their 5½-month-old infants in diverse communities in 11 countries (Argentina, Belgium, Brazil, Cameroon, France, Israel, Italy, Japan, Kenya, South Korea, and the United States). Rates of mothers' and infants' vocalizations varied widely across communities and were uncorrelated. However, collapsing the data across communities, we found that mothers' vocalizations to infants were contingent on the offset of the infants' nondistress vocalizing, infants' vocalizations were contingent on the offset of their mothers' vocalizing, and maternal and infant contingencies were significantly correlated. These findings point to the beginnings of dyadic conversational turn taking. Despite broad differences in the overall talkativeness of mothers and infants, maternal and infant contingent vocal responsiveness is found across communities, supporting essential functions of turn taking in early-childhood socialization.

Productive Vocabulary among Three Groups of Bilingual American Children: Comparison and Prediction

The importance of input factors for bilingual children's vocabulary development was investigated. Forty-seven Argentine, 42 South Korean, 51 European American, 29 Latino immigrant, 26 Japanese immigrant, and 35 Korean immigrant mothers completed checklists of their 20-month-old children's productive vocabularies. Bilingual children's vocabulary sizes in each language separately were consistently smaller than their monolingual peers but only Latino bilingual children had smaller total vocabularies than monolingual children. Bilingual children's vocabulary sizes were similar to each other. Maternal acculturation predicted the amount of input in each language, which then predicted children's vocabulary size in each language. Maternal acculturation also predicted children's English-language vocabulary size directly.

Modalities of infant-mother interaction in Japanese, Japanese American immigrant, and European American dyads

Cultural variation in relations and moment-to-moment contingencies of infant-mother person-oriented and object-oriented interactions were compared in 118 Japanese, Japanese American immigrant, and European American dyads with 5.5-month-olds. Infant and mother person-oriented behaviors were related in all cultural groups, but infant and mother object-oriented behaviors were related only among European Americans. Infant and mother behaviors within each modality were mutually contingent in all groups. Culture moderated lead-lag relations: Japanese infants were more likely than their mothers to respond in object-oriented interactions; European American mothers were more likely than their infants to respond in person-oriented interactions. Japanese American dyads behaved like European American dyads. Interactions, infant effects, and parent socialization findings are set in cultural and accultural models of infant-mother transactions.

Mother-infant socioemotional contingent responding in families by adoption and birth

Contingencies of three maternal and two infant socioemotional behaviors that are universal components of mother-infant interaction were investigated at 5 months in 62 mothers (31 who had adopted domestically and 31 who had given birth) and their first children (16 males in each group). Patterns of contingent responding were largely comparable in dyads by adoption and birth, although the two groups of mothers responded differentially to the two types of infant signals. Mothers in both groups were more responsive than infants in social and vocal interactions, but infants were more responsive in maternal speech-infant attention interactions. Family type × gender statistical interactions suggested a possible differential role of infant gender in establishing mother-infant contingencies in families by adoption and birth.

Parenting knowledge: experiential and sociodemographic factors in European American mothers of young children

Knowledge of child rearing and child development is relevant to parenting and the well-being of children. Using a sociodemographically heterogeneous sample of 268 European American mothers of 2-year-olds, we assessed the state of mothers' parenting knowledge; compared parenting knowledge in groups of mothers who varied in terms of parenthood and social status; and identified principal sources of mothers' parenting knowledge in terms of social factors, parenting supports, and formal classes. On the whole, European American mothers demonstrated fair but less than complete basic parenting knowledge; age, education, and rated helpfulness of written materials each uniquely contributed to mothers' knowledge. Adult mothers scored higher than adolescent mothers, and mothers improved in their knowledge of parenting from their first to their second child (and were stable across time). No differences were found between mothers of girls and boys, mothers who varied in employment status, or birth and adoptive mothers. The implications of variation in parenting knowledge and its sources for parenting education and clinical interactions with parents are discussed.

Child Temperament in Three U.S. Cultural Groups

Temperament among children (N = 111 20-month-olds) from three cultural backgrounds in the United States (Latin American, Japanese American, and European American) was investigated. In accord with a biobehavioral universalist perspective on the expression of early temperament, few significant group differences in child temperament were found, regardless of cultural background. However, factors associated with maternal reports of child temperament differed by cultural group. The findings provide insight into the nature of child temperament generally and temperament of children in immigrant families specifically as well as parenting in immigrant families.

Child and mother play in three U.S. cultural groups: comparisons and associations

Child and mother play (n = 113 20-month-olds) among South American Latino immigrants, Japanese immigrants, and European Americans in the United States was investigated. Culturally universal patterns of play dominated the findings. For example, no cultural differences in the prevalence of exploratory or symbolic play were found for either children or their mothers. Regardless of their culture, boys engaged in significantly more exploratory and less symbolic play than did girls when they played by themselves. Few relations were found between child play in the two play sessions. Across cultural groups, children's exploratory play was significantly positively related to both maternal demonstrations and solicitations of exploratory play. The results identify which realms of child growth, parenting, and family function call for special attention and cultural sensitivity, as well as which do not, in the dynamics of immigrant families.

Mother-Infant Person- and Object-Directed Interactions in Latino Immigrant Families: A Comparative Approach

Cultural variation in durations, relations, and contingencies of mother-infant person-and object-directed behaviors were examined for 121 nonmigrant Latino mother-infant dyads in South America, Latina immigrants from South America and their infants living in the United States, and European American mother-infant dyads. Nonmigrant Latina mothers and infants engaged in person-directed behaviors longer than Latino immigrant or European American mothers and infants. Mother and infant person-directed behaviors were positively related; mother and infant object-related behaviors were related for some cultural groups but not others. Nearly all mother and infant behaviors were mutually contingent. Mothers were more responsive to infants' behaviors than infants were to mothers. Some cultural differences in responsiveness emerged. Immigrant status has a differentiated role in mother-infant interactions.

Expressive Vocabulary in Language Learners From Two Ecological Settings in Three Language Communities

This study compared multiple characteristics of girls' and boys' vocabulary in 6 different linguistic communities-1 urban and 1 rural setting in each of 3 countries. Two hundred fifty-two mothers in Argentina, Italy, and the United States completed vocabulary checklists for their 20-month-old children. Individual variability was substantial within each linguistic community. Minimal cross-linguistic differences were found in children's vocabulary size; however, differences among languages in the composition of children's vocabularies appeared possibly related to cultural valuing of different categories of words. Ecological setting differences within cultures appeared in children's vocabulary size, even when the composition of children's vocabularies was examined: Children living in urban areas were reported by their mothers to say significantly more words than children living in rural areas, particularly for Argentine and U.S. children. Girls had consistently larger vocabularies than boys. These findings are discussed in terms of contextual and child factors that together influence first language learning.

Cross-linguistic analysis of vocabulary in young children: spanish, dutch, French, hebrew, italian, korean, and american english

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.

"Who is sitting across from me?" Immigrant mothers' knowledge of parenting and children's development

OBJECTIVE

Although parents' knowledge about child development and child rearing is relevant to pediatric practice, very little is known about immigrant parents' knowledge. To fill this gap in research, this study investigated parenting knowledge in 2 groups of mothers who had immigrated to the United States.

DESIGN

Japanese and South American immigrant mothers of 2-year-olds completed a standardized survey of parenting knowledge and provided information about sociodemographic and infant health status. Their data were compared with European American mothers in the United States.

RESULTS

Immigrant mothers scored approximately 70% on the evaluation of parenting knowledge, significantly lower than multigenerational US mothers. The majority of immigrant mothers did not know correct answers for 25% of the items, and their incorrect answers were mostly to questions about normative child development.

CONCLUSIONS

Parents' knowledge is relevant to pediatricians' evaluations of the health and welfare of children as understood by their parents. Gaps in parenting knowledge have implications for clinical interactions with parents, child diagnosis, pediatric training, and parent education.

Mothers' Parenting Cognitions in Cultures of Origin, Acculturating Cultures, and Cultures of Destination

Japanese and South American immigrant mothers' parenting cognitions (attributions and self-perceptions) were compared with mothers from their country of origin (Japan and Argentina, respectively) and European American mothers in the United States. Participants were 231 mothers of 20-month-old children. Generally, South American immigrant mothers' parenting cognitions more closely resembled those of mothers in the United States, whereas Japanese immigrant mothers' cognitions tended to be similar to those of Japanese mothers or intermediate between Japanese and U.S. mothers. This study provides insight into the nature of parenting cognitions generally and those of immigrant mothers specifically and therefore the parenting climate in which immigrant children are reared.

Parenting beliefs and behaviors in northern and southern groups of Italian mothers of young infants

Similarities and differences in northern and southern Italian mothers' social and didactic parenting beliefs and behaviors, and relations between their beliefs and behaviors, are reported. Both groups of mothers reported that they engaged more in social than didactic interactions with their infants, whereas in actuality both groups engaged in didactic behaviors with their infants for longer periods of time than they engaged in social behaviors. In addition, northern mothers engaged in more social interactions with their infants than did southern mothers. No correlations between beliefs and behaviors emerged in either group. These data speak to issues of intracultural variation and cross-cultural similarities in family psychology and parenting, belief-behavior relations in parenting, and the importance of methodology (parental report or observation) in the study of parenting and family functioning.
