Contributions of Biological Resident Fathers to Early Language Development in Two-parent Families from Low-income Rural Communities

This dissertation developed and empirically tested a multidimensional model of biological resident fathers’ distal and proximal contributions during infancy to children’s later language development using the Family Life Project dataset. The Family Life Project dataset included a large sample of 521 two-parent middle-income and low-income African-American and non-African-American families. The results of this study suggest fathers made contributions to children’s communication and language development via characteristics of family SES, father work experience, the mother-father relationship, and father-child proximal processes. Specifically, higher family SES, positive father reasoning skills in the mother-father relationship, and highly engaging and stimulating father-child interactions when children are 6 months were significantly associated with more advance child communication at 15 months and expressive language development at 24 months. Father job insecurity when children were 6 months was negatively associated with child language development at 24 months

Fathers’ early contributions to children's language development in families from low-income rural communities

This study utilized a large sample of two-parent families from low-income rural communities to examine the contributions of father education and vocabulary, during picture book interactions with their infants at 6 months of age, to children’s subsequent communication development at 15 months and expressive language development at 36 months. After controlling for family demographics, child characteristics, as well as mother education and vocabulary, father education and father vocabulary during the picture-book task were related to more advanced language development at both 15 and 36 months of age. Only mother education, but not vocabulary during book-reading was related to children’s later language. These findings support the growing evidence on the importance of fathers in understanding children’s early communication and language development

Work characteristics and fathers' vocabulary to infants in African American families

Fathers’ vocabulary to infants has been linked in the literature to early child language development, however, little is known about the variability in fathers’ language behavior. This study considered associations between fathers’ work characteristics and fathers’ vocabulary among a sample of employed African American fathers of 6-month old infants who were living in low-income rural communities. After controlling for family and individual factors, we found that fathers who worked nonstandard shifts and reported more job flexibility used more diverse vocabulary with their infants

Family relationships during infancy and later mother and father vocabulary use with young children

Very little previous research has considered the contributions of family relationships and interactions on the language input of mothers and fathers to their young children. This study examined the contributions of marital love and conflict, and broader family-level conflict, cohesion, and expressiveness to mother and father vocabulary in triadic interactions with their young children in 70 dual-earner families. It was found that after controlling for parent sensitivity and parent directive behavior, marital love and family conflict when children were 12 months of age were significant predictors of both father vocabulary and mother vocabulary to children at 24 months of age. In families with higher levels of marital love when children were 12 months of age, mothers and fathers used a more diverse vocabulary with their 24 month-old children. In families with lower levels of family conflict when children were 12 months of age, mothers and fathers used a more diverse vocabulary with their 24 month-old children

Predictors of maternal language to infants during a picture book task in the home: Family SES, child characteristics and the parenting environment

This study investigated the contribution of child characteristics and parenting environment to the relationship between family SES/demographic characteristics and maternal language to infants.1157 children were drawn from a representative sample of 1292 infants born to mothers in rural Appalachian counties and rural counties in southern minority U.S. communities. Mothers and their 6–8 month old babies were videotaped at home while talking about a wordless picture book. Mothers' language output and complexity were analyzed. Child temperament, age, and parenting environment (knowledge of child development and observed mother–child engagement) were predictors of maternal language. Furthermore, their inclusion reduced the magnitude of the association between demographic characteristics and maternal language. Tests of mediation suggested that the parenting environment partially mediates the relationship between SES/demographic characteristics and maternal language. Findings are discussed with respect to identifying proximal processes that explain how SES may exert its influence on the language of young children

How much exposure to English is necessary for a bilingual toddler to perform like a monolingual peer in language tests?

Background Bilingual children are under-referred due to an ostensible expectation that they lag behind their monolingual peers in their English acquisition. The recommendations of the Royal College of Speech and Language Therapists (RCSLT) state that bilingual children should be assessed in both the languages known by the children. However, despite these recommendations, a majority of speech and language professionals report that they assess bilingual children only in English as bilingual children come from a wide array of language backgrounds and standardized language measures are not available for the majority of these. Moreover, even when such measures do exist, they are not tailored for bilingual children. Aims It was asked whether a cut-off exists in the proportion of exposure to English at which one should expect a bilingual toddler to perform as well as a monolingual on a test standardized for monolingual English-speaking children. Methods & Procedures Thirty-five bilingual 2;6-year-olds exposed to British English plus an additional language and 36 British monolingual toddlers were assessed on the auditory component of the Preschool Language Scale, British Picture Vocabulary Scale and an object-naming measure. All parents completed the Oxford Communicative Development Inventory (Oxford CDI) and an exposure questionnaire that assessed the proportion of English in the language input. Where the CDI existed in the bilingual's additional language, these data were also collected. Outcomes & Results Hierarchical regression analyses found the proportion of exposure to English to be the main predictor of the performance of bilingual toddlers. Bilingual toddlers who received 60% exposure to English or more performed like their monolingual peers on all measures. K-means cluster analyses and Levene variance tests confirmed the estimated English exposure cut-off at 60% for all language measures. Finally, for one additional language for which we had multiple participants, additional language CDI production scores were significantly inversely related to the amount of exposure to English. Conclusions & Implications Typically developing 2;6-year-olds who are bilingual in English and an additional language and who hear English 60% of the time or more, perform equivalently to their typically developing monolingual peers

How well do European child-related leave policies support the caring role of fathers?

Our chapter analyses the extent to which European countries (1) recognize the caring responsibilities of fathers toward their children and (2) value fathers' caring role. To do so, we analyze the designs of individual leave policies and reflect on them by assessing available data on leave uptake by fathers in 13 European countries. Our results show that there is great variation in child-related leave designs across Europe. Our findings, in line with previous work, underscore the importance of generous individual non-transferable leave entitlements. Moreover, our findings bring forward aspects of leave designs that are rarely discussed when considering fathers' leave uptake. Our results indicate that generous non-transferable leave rights should be paired with (a) clearly defined leave periods for fathers, (b) individual entitlement to benefits, and (c) greater scope for flexibility to increase the attractiveness of child-related leave and to strengthen fathers' position when negotiating their childcare leave.</p
