This article evaluates the acquisition of directionals in Q'anjob'al, a Western Mayan language of Guatemala. The data come from a longitudinal study of two Q'anjob'al monolingual children of Santa Eulalia, Huehuetenango, Guatemala: Xhuw (1;9-2;5) and Xhim (2;3-3;5). The results show how these children acquire the morphological distribution of…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

Data from 83,423 parent reports of temperament (surgency, negative affectivity, and regulatory capacity) in infants, toddlers, and children from 341 samples gathered in 59 countries were used to investigate the relations among culture, gender, and temperament. Between-nation differences in temperament were larger than those obtained in similar…

We compared dyad-focused maternal speech (protoconversations and maternal speech describing the dyad) in interactions of mothers with their twin and singleton infants. Nine twins and nine singletons, coming from urban areas of Crete (Greece), were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to…

The current study examines the association between the mother-caregiver relationship and the psychological well-being of 533 mothers who transitioned their children to a non-familial licensed childcare center. Maternal well-being, mother-caregiver relationship quality, and maternal parenting stress were assessed. Hierarchical linear regressions…

Background: Despite evidence on their short-term effectiveness, the long-term effects of group-based parenting interventions are unclear, programs are hard to scale up, and effects on parents of infants and toddlers are mixed. Objective: We evaluate the impact of a parenting intervention, "Crianza Positiva," that combines 8 group…

This longitudinal multiple-case study research focused on the scaffolding strategies that two Israeli deaf mothers use to boost their young hearing children's engagement in reading interactions. Despite being significant to language learning, few studies have examined the dialogic reading practices of deaf-signing mothers. The study shows that…

The present study explored the association between the structural quality of child care, caregivers' sensitive responsiveness, children's involvement in play and activity in the setting, and children's expression of aggression. Eighty-four early childhood care settings were classified into either high (29) or low structural quality (55) based on…

Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

There is a great deal of variability in how families read and interact with picture books. To understand why reading practices may (or may not) relate to language outcomes, a necessary step to understand what occurs in the home. The goal of this work is to better understand the frequency and nature of picture book reading at home with children…

Reflective supervision (RS) has been viewed as best practice and is therefore incorporated--and often mandated--as a key feature of many relationship-based infant and early childhood serving programs. To promote the implementation of high-quality RS for infant and early childhood professionals, it is critical that a focus is placed on…

This user-friendly guide uses narrative storytelling to describes the principles of early relational health with direct application to day-to-day work with infants and parents. Practitioners on the front lines often feel great pressure to know "what to do" in a wide range of challenging situations. Drawing on both developmental science…

The authors of this article identify the status of the COVID-19 pandemic in Nigeria and propose the use of a classic strategic planning paradigm to mitigate its spread until it may be completely arrested. Vaccines have been developed to combat the disease which current evidence suggests is spread by respiratory droplets among people who are in…

Previous research assessing consequences of interpregnancy intervals (IPIs) on child development is mixed. Utilizing a population-based US sample (n = 5339), we first estimate the associations between background characteristics (e.g. sociodemographic and maternal characteristics) and short ([less than or equal to]1 year) and long (>3 years)…

Dysregulation of diurnalcortisol rhythms is often seen among children exposed to early adversity and has been associated with a variety of negative physical and mental health outcomes. The present study examined whether two indicators of deprivation, sociodemographic burden and observed parental insensitivity, were associated with child diurnal…
