Mother-child and father-child "serve and return" interactions at 9 months: Associations with children's language skills at 18 and 24 months.

Infants learn language through the back-and-forth interactions with their parents where they "serve" by uttering sounds, gesturing, or looking and parents "return" in prompt (i.e., close in time) and meaningful (i.e., semantically relevant to the object of interest) ways. In a sample of 9-month-old infants (n = 148) and their mothers and fathers (n = 296 parents) from ethnically and socioeconomically diverse backgrounds, we examined the associations between "serve and return" (SR) parent-child interactions and children's language skills at 18 and 24 months. We also examined the moderation effects between maternal and paternal SR interactions on language outcomes. SR interactions were transcribed and coded from videotaped parent-child toy play activities during home visits. We report three findings. First, mothers who provided more meaningful responses to their child's serves at 9 months had children with higher expressive language scores at 18 months. Second, fathers' prompt responses (i.e., within 3 s) at 9 months were associated with higher receptive language scores at 18 months, but their meaningful responses were negatively associated with receptive language scores at 24 months. Third, the negative association between fathers' meaningful responses and children's receptive language scores was reduced (compensated) when mothers' meaningful responses were high. Findings show that infants in ethnically and socioeconomically diverse families engage in frequent SR interactions with both mothers and fathers, who make unique contributions to infants' language development. We discuss implications for programs and policies that aim to promote early language development and reduce gaps in school readiness.

A meta-analysis on observed paternal and maternal sensitivity.

Two meta-analyses were conducted (N = 10,980 child-father dyads) with 93 studies published between 1983-2020, primarily in North America and Europe, on observed parental sensitivity to children (3-180 months; 48% girls; 14% non-White) in partnered mothers and fathers. The first meta-analysis found higher maternal mean levels of observed sensitivity, with a small effect size (d = -.27). Differences between parents were larger with micro coding and triadic/family assessments. Differences narrowed as a function of publication year and were not significant in European samples. The second meta-analysis identified a moderate correlation between observed maternal and paternal sensitivity (r = .23 after adjusting for probable publication bias). Correlations were larger in Middle Eastern samples and with composite sensitivity scales.

Commentary: Recognizing our similarities and celebrating our differences - parenting across cultures as a lens toward social justice and equity.

Lansford (2021) has aptly and eloquently reviewed the vast scholarly research on cross-cultural parenting and concludes that similarities in parenting norms and behaviors across cultures reflect universally adaptive behaviors for children's development. Culture-specific differences are due largely to environmental constraints and affordances as well as cultural norms for expected behavior. This is an exemplar review that tells a clear story of what we have learned from the decades of research on this topic and lays the foundation for future scholarship. Specially compelling is Lansford's argument that we need to take stock of what we know and conduct more of this type of research because the majority of what we have now is biased and does not represent the parenting practices of an increasingly diverse population. In this commentary, I provide some context for the value and potential pitfalls of cross-cultural research; discuss the importance of theoretically driven research; discuss the benefits of cross-cultural research; and conclude with some ideas for future investigations.

Next Directions in Measurement of the Home Mathematics Environment: An International and Interdisciplinary Perspective.

This article synthesizes findings from an international virtual conference, funded by the National Science Foundation (NSF), focused on the home mathematics environment (HME). In light of inconsistencies and gaps in research investigating relations between the HME and children's outcomes, the purpose of the conference was to discuss actionable steps and considerations for future work. The conference was composed of international researchers with a wide range of expertise and backgrounds. Presentations and discussions during the conference centered broadly on the need to better operationalize and measure the HME as a construct - focusing on issues related to child, family, and community factors, country and cultural factors, and the cognitive and affective characteristics of caregivers and children. Results of the conference and a subsequent writing workshop include a synthesis of core questions and key considerations for the field of research on the HME. Findings highlight the need for the field at large to use multi-method measurement approaches to capture nuances in the HME, and to do so with increased international and interdisciplinary collaboration, open science practices, and communication among scholars.

The Protective Effects of Maternal and Paternal Factors on Children's Social Development.

The goal of this study is to examine associations among family and child protective factors, maternal and paternal levels of distress, and children's social competence in a sample of 156 ethnically and socioeconomically diverse first-time mothers, fathers, and their children, followed from 9 months to 30 months of age. Using multiple linear regression modeling, our results indicate that dyadic synchrony and children's positive temperament during infancy are significantly associated with fewer behavior problems and paternal optimism with high levels of social competence at 21 months (main effects). Father optimism and child positive temperament are only significantly related to higher levels of social competence and fewer behavioral problems, respectively, in the context of low levels of paternal distress (interaction effects). These results suggest that in our sample maternal dyadic synchrony operates in the same way across levels of maternal distress as it relates to children's behavior problems, with the exception of paternal optimism and children's positive temperament. Results also suggest that protective factors are different for mothers, fathers, and children.

Cognitive Stimulation at Home and in Child Care and Children's Preacademic Skills in Two-Parent Families.

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children's pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of fathers' early cognitive stimulation on early reading and math skills at 48 and 60 months. There were also two moderated effects: The effects of high levels of maternal stimulation at 24 months on early math and reading skills at 48 months were largest for children also receiving high levels of cognitive stimulation from their childcare providers. Implications for including fathers in studies of the home cognitive stimulation and strengthening the parent-childcare connection are discussed.

Children's Adjustment to Parents' Break Up: The Mediational Effects of Parenting and Co-parenting.

Although past studies have shown an association between union instability (i.e., change in family structure) and children's aggressive behaviors, the mechanism by which this occurs is less understood. This study (n = 3,387) examined whether father and mother involvement, co-parenting support, and maternal responsiveness explained the association between union instability in early life and children's aggressive behaviors at 9 years, and whether relationship status moderated this association. Findings reveal that only co-parenting support mediated this association and only for children whose mothers divorced (not for mothers who experienced a non-marital separation), suggesting that when a divorce occurs, the relationship between partners (co-parenting) is more important than the relationship with children (parenting) for children's social adjustment.

Father involvement, father-child relationship, and attachment in the early years.

Over the last few decades fathers have become an increasing presence in research, yet research on fathers still lags behind that on mothers. In fact, most research on parents still includes the mother. Consequently, there is still much to learn about fathers. This is particularly true for understanding how parent-child relationship functioning in the early years can serve as a source of emotional security that promotes healthy development across developmental domains and across the lifespan. In this commentary, I take a social policy broad lens to highlight the empirical and theoretical connections among father- relationship, father involvement, and father-child attachment.

Young Latinx children: At the intersections of race and socioeconomic status.

To understand the developmental outcomes of Latinx children growing up poor in the United States, we examine how socioeconomic status (SES) and ethnic minority status jointly condition the development of Latinx children in the United States. To address these gaps, in this chapter we first present a brief demographic profile of Latinx in the United States to contextualize the later theoretical and empirical discussions. We then review theoretical frameworks that explain SES differences in Latinx home environments and examine how they have been used to explain disparities in Latinx children's outcomes. Third, we describe the current research on the early home environments of Latinx children of varying levels of parental SES. Fourth, we review the literature on Latinx children's inequalities noting the scarcity of research that compares Latinx to White children or Latinx to Black children compared to the studies that focus on the White-Black academic gap. Finally, we conclude by summarizing state of knowledge and offering suggestions for future directions. We focus on young children (0-8) due to space limitations but also because the early childhood period is foundational to later development and is where the effects of poverty most likely to have enduring effects.

Advancing Research and Measurement on Fathering and Child Development.

Fathers are more than social accidents. Research has demonstrated that fathers matter to children's development. Despite noted progress, challenges remain on how best to conceptualize and assess fathering and father-child relationships. The current monograph is the result of an SRCD-sponsored meeting of fatherhood scholars brought together to discuss these challenges and make recommendations for best practices for incorporating fathers in studies on parenting and children's development. The first aim of this monograph was to provide a brief update on the current state of research on fathering and to lay out a developmental ecological systems perspective as a conceptual framework for understanding the different spaces fathers inhabit in their children's lives. Because there is wide variability in fathers' roles, the ecological systems perspective situates fathers, mothers, children, and other caregivers within an evolving network of interrelated social relationships in which children and their parents change over time and space (e.g., residence). The second aim was to present examples of empirical studies conducted by members of the international working group that highlighted different methods, data collection, and statistical analyses used to capture the variability in father-child relationships. The monograph ends with a commentary that elaborates on the ecological systems framework with a discussion of the broader macrosystem and social-contextual influences that impinge on fathers and their children. The collection of articles contributes to research on father-child relationships by advancing theory and presenting varied methods and analysis strategies that assist in understanding the father-child relationship and its impact on child development.

THE MAGIC OF PLAY: LOW-INCOME MOTHERS' AND FATHERS' PLAYFULNESS AND CHILDREN'S EMOTION REGULATION AND VOCABULARY SKILLS.

Using data from a diverse sample of low-income families who participated in the Early Head Start Research Evaluation Project (n = 73), we explored the association between mothers' and fathers' playfulness with toddlers, toddler's affect during play, and children's language and emotion regulation at prekindergarten. There were two main findings. First, fathers' playfulness in toddlerhood was associated with children's vocabulary skills in prekindergarten whereas mothers' playfulness was related to children's emotion regulation. Cross-parental effects were found only for mothers. The association between mothers' playfulness and children's vocabulary and emotion regulation was strengthened when fathers engaged in more pretend play and when children were affectively positive during the play. These findings show that playfulness is an important source of variation in the vocabulary and emotion regulation of children growing up in low-income families. They also point to domain-specific ways that mothers and fathers promote children's regulatory and vocabulary skills, and highlight the importance of children's positive engagement in play.

FATHER PLAY: IS IT SPECIAL?

Both mothers and fathers play with their children, but research on parent-child play interactions is conducted with mothers three times more often than it is with fathers. The articles in this special issue address this gap by focusing on the nature and quality of father-child play, across cultural contexts, and considering whether father play offers something unique and special for early human development, in infancy or early childhood. The studies show that fathers can be just as developmentally supportive as are mothers in terms of being playful and engaged with their children in ways that are related to greater child socioemotional competence, emotion regulation, and vocabulary, and to less aggression, anxiety, and negativity. We encourage future research to examine the cultural influences, family system dynamics, and specificity of timing and types of father-child play in relation to children's developmental competence.

THE EARLY HOME ENVIRONMENT OF LATINO BOYS AND THEIR PEERS: A DEVELOPMENTAL PERSPECTIVE.

Using a sample (N = 5,200) drawn from the Early Childhood Longitudinal Study-Birth Cohort, we examined Latino boys' developmental profiles and their early home experiences from 9 months to kindergarten entry in comparison to their peers-Latina girls and White boys. We also examined how children's early home experiences related to outcomes at kindergarten entry and whether these varied by gender and ethnicity. Controlling for socioeconomic indicators, the largest mean group differences were between Latino and White boys, beginning at 24 months and persisting at kindergarten entry. There were modest differences between Latino boys and Latina girls on some outcomes, with boys showing an early and persistent advantage in math and girls showing a persistent advantage in social skills. Household resources and maternal and paternal investments in literacy activities were the strongest predictors of children's preacademic skills at kindergarten entry. Our model did not vary by gender or ethnicity, suggesting that the ingredients for learning are the same for all children.

Low-income fathers' speech to toddlers during book reading versus toy play.

Fathers' child-directed speech across two contexts was examined. Father-child dyads from sixty-nine low-income families were videotaped interacting during book reading and toy play when children were 2;0. Fathers used more diverse vocabulary and asked more questions during book reading while their mean length of utterance was longer during toy play. Variation in these specific characteristics of fathers' speech that differed across contexts was also positively associated with child vocabulary skill measured on the MacArthur-Bates Communicative Development Inventory. Results are discussed in terms of how different contexts elicit specific qualities of child-directed speech that may promote language use and development.

Low-income minority mothers' and fathers' reading and children's interest: Longitudinal contributions to children's receptive vocabulary skills.

Using data from a diverse sample of low-income African American and Latino mothers, fathers, and their young children who participated in Early Head Start (n = 61), the current study explored the association between parents' reading quality (i.e. metalingual talk) while reading with their 2-year-old children and their children's receptive vocabulary skills at pre-kindergarten. It further examined whether children's interest in reading mediated this association. There were three main findings. First, most mothers and fathers in our sample read relatively often to their children (a few times a week) and used some metalingual talk; fathers used more than mothers. Second, controlling for parental education, mothers' and fathers' early reading quality significantly predicted children's receptive vocabulary skills at pre-kindergarten. Third, children's interest in reading mediated the association between mothers' and fathers' reading quality and children's receptive vocabulary scores. These findings have important implications for programs aimed at fostering low-income children's vocabularies and suggest that both mothers and fathers need to be included in programs.

Low-income, minority fathers' control strategies and their children's regulatory skills.

The current study explored the bidirectional association of children's individual characteristics, fathers' control strategies at 24 months, and children's regulatory skills at prekindergarten (pre-K). Using a sample of low-income, minority families with 2-year-olds from the Early Head Start Research and Evaluation Project (n = 71), we assessed the association between child gender and vocabulary skills, fathers' control strategies at 24 months (e.g., regulatory behavior and regulatory language), and children's sustained attention and emotion regulation at prekindergarten. There were three main findings. First, fathers overwhelmingly used commands (e.g., "Do that.") to promote compliance in their 24-month-old children. Second, children's vocabulary skills predicted fathers' regulatory behaviors during a father-child interaction whereas children's gender predicted fathers' regulatory language during an interaction. Third, controlling for maternal supportiveness, fathers' regulatory behaviors at 24 months predicted children's sustained attention at pre-K whereas fathers' regulatory language at 24 months predicted children's emotion regulation at pre-K. Our findings highlight the importance of examining paternal contributions to children's regulatory skills.

Father input and child vocabulary development: the importance of Wh questions and clarification requests.

Individual differences in children's language skills have been shown to stem in part from variations in the quantity and quality of parent speech input. However, most research focuses on mothers' input whereas less is known about the effects of variability in father input. In this article, we review the relation between parent input and child language development with a focus on low-income families, and review general findings about similarities and differences in mother and father speech. Within this review, we highlight conversation-eliciting speech, such as wh questions and clarification requests, which occur, on average, more frequently in father input than mother input. Conversation-eliciting speech is challenging for 2-year-old children and has been shown in research with mothers to relate to child vocabulary development. We then report a study examining whether fathers' use of conversation-eliciting speech relates to children's developing vocabulary skills at 24 months of age within a sample of low-income African American families. Understanding that speech input varies among fathers, and specific strengths that fathers bring to interactions with their young children can help speech-language pathologists develop and implement more effective interventions.

Coparenting and children's school readiness: a mediational model.

We examined the long-term direct and indirect links between coparenting (conflict, communication, and shared decision-making) and preschoolers' school readiness (math, literacy, and social skills). The study sample consisted of 5,650 children and their biological mothers and fathers who participated in the Early Childhood Longitudinal Study-Birth Cohort. Using structural equation modeling and controlling for background characteristics, we found that our conceptual model of the pathways from coparenting to child outcomes is structurally the same for cohabiting and married families. Controlling for a host of background characteristics, we found that coparenting conflict and shared decision-making were negatively and positively, respectively, linked to children's academic and social skills and co-parental communication was indirectly linked to academic and social skills through maternal supportiveness. Coparenting conflict was also indirectly linked to children's social skills through maternal depressive symptoms. The overall findings suggest that for both cohabiting and married families, the context of conflicted coparenting may interfere with the development of children's social competencies and academic skills, whereas collaborative coparenting promotes children's school readiness because mothers are more responsive to their children's needs. These findings have implications for programs aimed at promoting positive family processes in cohabiting and married families.

Father-toddler communication in low-income families: The role of paternal education and depressive symptoms.

Using data from a racially and ethnically diverse sample of low-income fathers and their 2-year-old children who participated in the Early Head Start Research Evaluation Project (n = 80), the current study explored the association among paternal depressive symptoms and level of education, fathers' language to their children, and children's language skills. There were three main findings. First, there was large variability in the quality and quantity of language used during linguistic interactions between low-income fathers and their toddlers. Second, fathers with higher levels of education had children who spoke more (i.e. utterances) and had more diverse vocabularies (i.e. word types) than fathers with lower levels of education. However, fathers with more depressive symptoms had children with less grammatically complex language (i.e. smaller MLUs) than fathers with fewer depressive symptoms. Third, direct effects between fathers' depressive symptoms and level of education and children's language outcomes were partially mediated by fathers' quantity and quality of language.

Patterns and predictors of father-infant engagement across race/ethnic groups.

This study examines whether levels of father engagement (e.g., verbal stimulation, caregiving, and physical play) vary by race/ethnicity using a model that controls for fathers' human capital, mental health, and family relationships. It also tests whether the models work similarly across race/ethnic groups. Its sample of N=5,089 infants and their families is drawn from the Early Childhood Longitudinal Study - Birth Cohort (ECLS-B). We found that, after including controls, African American and Latino fathers had higher levels of engagement in caregiving and physical play activities than White fathers. There were no differences in verbal stimulation activities across race/ethnicity. Fathers' education (college level) predicted more verbally stimulating activities whereas fathers' report of couple conflict predicted less caregiving and physical play. Although levels of engagement differed across the groups, the overall models did not differ by race/ethnicity, except for physical play. African American mothers who reported high levels of depressive symptoms had partners who engaged in more physical play than White mothers with high levels of depressive symptoms.
