The number of U.S. children living in households with extended families has greatly increased in the last 4 decades. This demographic shift calls for a reevaluation of the impact of household size on children's development. Household density (HHD), measured as the ratio of people to bedrooms in a home, has been shown to negatively relate to…

Prior studies of mother-infant interaction have generally used a variable-centered approach to associate face-to-face communication with psychosocial outcomes. Herein, we use a person-centered approach to identify clusters of infants who exhibit similar behavioral profiles during face-to-face communication with their mothers. Four infant…

Although early life experiences of language and parenting are critical for children's development, large home observation studies of both domains are scarce in the psychological literature, presumably because of their considerable costs to the participants and researchers. Here, we used digital audio-recorders to unobtrusively observe 107…

Understanding the role of negative emotionality in the development of executive functioning (EF) and language skills can help identify developmental windows that may provide promising opportunities for intervention. In addition, because EF and language skills are, in part, genetically influenced, intergenerational transmission patterns are…

This study aimed to test a 5-wave sequential mediation model linking maternal mind-mindedness during infancy to children's school readiness in kindergarten through a serial mediation involving child language and effortful control in toddlerhood and the preschool years. Among a sample of 204 mother-child dyads, we assessed maternal mind-mindedness…

Recent studies demonstrate that emerging literacy depends on earlier language achievement. Importantly, most extant work focuses on "parent-reported production" prior to 30 months of age. Of interest is whether and how "directly assessed vocabulary comprehension" in the 2nd year of life supports vocabulary and kindergarten…

This 4-wave longitudinal study evaluated stability of core language skill in 421 European American and African American children, half of whom were identified as low (n = 201) and half of whom were average-to-high (n = 220) in later language skill. Structural equation modeling supported loadings of multivariate age-appropriate multisource measures…

For the 5 million low-income Latino children in the United States who are disproportionately impacted by the numerous risk factors associated with poverty, it is essential to identify proximal protective factors that mitigate these risks and bolster the academic and social skills that are foundational to a successful transition into formal…

Until recently, the challenges inherent in measuring comprehension have impeded our ability to predict the course of language acquisition. The present research reports on a longitudinal assessment of the convergent and predictive validity of the MacArthur-Bates Communicative Development Inventories: Words and Gestures (CDI: WG; Fenson et al.,…

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS…

Sampled the speech of American, French, and Swedish mothers to their one-year olds, to analyze distribution of phonetic parameters of adult speech, as well as children's own early words. Found that variability is greater in child words than in adult speech, and mother-child dyads showed no evidence of specific maternal influence on phonetics of…

Two sets of meta-analyses examined gender effects on parents' observed language with their children. Findings indicated that mothers talked more, used more supportive and negative speech, and less directive and informing speech than fathers. Mothers talked more and used more supportive speech with daughters than sons. Effect sizes depended on…

Tested predictions of infantile amnesia theory compared with social-interactionist account of autobiographical memory. Found maternal reminiscing style and self-recognition when child was 19 months old uniquely predicted children's shared memory reports across time, even with children's initial language and nonverbal memory factored out.…

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Forty 3.5- to 4.5-year-olds discussed past events with their mothers and completed tasks indexing their ability to reason about conflicting mental representations and understanding of knowledge. Found that theory-of-mind scores were related to memory conversation participation, independent of age and linguistic skill, and to the frequency of…
