Perceptual narrowing of speech perception supposes that young infants can discriminate most speech sounds early in life. During the second half of the first year, infants' phonetic sensitivity is attuned to their native phonology. However, supporting evidence for this pattern comes primarily from learners from a limited number of regions and…

Emphasis on continuous infant sleep overnight may be driven by parental concern of risk to child mental health outcomes. The Mercy Pregnancy and Emotional Wellbeing Study (MPEWS) examined whether infant sleep at 6 and 12 months postpartum predicts anxiety disorders at 2-4 years, and whether this is moderated by maternal depression, active physical…

We provide the first causal evidence of the returns to maternal educational curricula on offspring's health at birth. Educational programs that aim to deliver more general knowledge may potentially improve women's earning potential and maternal prenatal investment by increasing the portability of skills across occupations and improving women's…

Preterm birth poses a major public health challenge, with significant and heterogeneous developmental impacts. Latent profile analysis was applied to the National Institutes of Health Toolbox performance of 1891 healthy prematurely born children from the Adolescent Brain and Cognitive Development study (970 boys, 921 girls; 10.00 ± 0.61 years;…

Introduction: Children's early language and communication skills are efficiently measured using parent report, for example, communicative development inventories (CDIs). These have scalable potential to determine risk of later language delay, and associations between delay and risk factors such as prematurity and poverty. However, there may be…

Functional magnetic resonance imaging (fMRI) studies with adults provide evidence that functional brain networks, including the default mode network and frontoparietal network, underlie executive functioning (EF). However, given the challenges of using fMRI with infants and young children, little work has assessed the developmental trajectories of…

The current study examined the inter-brain coherence (IBC) between 34 dyads of fathers and infants 7-9 months of age using functional near-infrared spectroscopy (fNIRS). We specifically focused on father-infant IBC to broaden the empirical base beyond the mother-infant connections, as the former has received limited attention. There were three…

Background: Mucopolysaccharidosis type III (MPS III) is a rare lysosomal storage disease with systemic complications. This scoping review aimed to synthesise evidence regarding methods to diagnose and monitor MPS III. Methods: We searched 10 databases for English and Spanish citations published from 2017 to 2022. Our study focused on human-based…

Several researchers have found that media exposure through books or electronic media contribute to preschoolers' development. However, research with behavioral measures and during the first years of life have not been carried out in Latin American contexts. The aim of the following research was to evaluate the relations between media exposure…

This study has been conducted to examine the relationship levels of fathers who have 6- to 12-month-old babies with their fathers, and their attachment status with their babies. The sample group consisted of 313 fathers. Fatherhood Scale and Father-Infant Attachment Scale have been applied to the fathers who participated in our study,…

This study was carried out to determine the effects of posttraumatic stress disorder (PTSD) on maternal adaptation and newborn perception in postpartum primiparous mothers. The research was designed as descriptive and cross-sectional. A total of 378 mothers who were in postpartum 6-8 weeks were reached. Of the 378 mothers participating in the…

Hierarchical linear modelling was used to explore the effect of changes in maternal sensitivity on attachment over time. Child characteristics of gender, temperament, and developmental status were used as moderating factors. Data from 1,249 mothers and their children from the NICHD Study of Early Child Care and Youth Development when the children…

We compared speech acts and complexity of maternal speech to firstborn dizygotic twin and singleton infants. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to the 6th month. Continuous micro-analysis revealed that (a) open-ended questions, direct requests,…

This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

Gradients across socioeconomic status occur for many children's health and improvement in high-income countries. The objective is to explore infant growth and child development in four developed countries around the socioeconomic landscape. In this paper, Structural Equation Modeling (SEM) enhances the socioeconomic status gradients for the…
