Very few studies have assessed infant capacity for bidirectional, contingent communication at birth, and to our knowledge there are none with preterm infants in the neonatal period. Presence versus absence of such interactive contingency makes a difference for our theories of development. We examined whether preterm infants can contingently…

We estimated risk factors associated with suspected neuropsychomotor developmental delay at age 2 years, in a birth cohort in the Brazilian Amazon. The Maternal and Child Health and Nutrition in Acre (MINA-Brasil) study is a population-based birth cohort involving children born between July 2015 and June 2016 in the municipality of Cruzeiro do…

In this study, infant vocabulary development was tracked in a multilingual society (Singapore) within a socioeconomically diverse sample. The sample comprised 1316 infants from 17.4 to 27.7 months (669 females, 647 males; 88% Chinese race, 4% Malay, 4% Indian, and 0.004% mixed-race [4% declined to provide race information]). Children varied in…

This study examined implementation of a newly developed shared book reading intervention program, to boost infants' early skills and provide a solid foundation for continued language learning. A randomised control study was conducted to elevate the effects of Shared Book Reading Intervention with 20 parents (n = 10 experiment, n = 10 control) and…

Understanding the impact of preemptive interventions on development for those with a high likelihood for autism is a critical step in building a transdiagnostic model of optimized intervention. The purpose of this systematic review and meta-analysis is to examine the impact of preemptive autism interventions on parent outcomes and child…

Several studies have analysed the impact of attending early childhood education centres on communication, regulatory skills and social-emotional development. These educational institutions have increased in presence annually, partially due to the access of women to the labour market. It has been found that infant education may modulate development…

Expanding Quality in Infant Toddler Care is a professional development initiative that is relationship-based on every level. It is administrated by the Colorado Office of Early Childhood. Instructors get intensive training and become members of the Infant Toddler Specialist network. Every level of the EQ Initiative uses an open framework called…

The acoustic properties of infant-directed speech (IDS) have been widely studied, but whether and how young learners' language development benefits from individual properties remains to be confirmed. This study investigated whether toddlers' word processing was affected by tone hyperarticulation in the IDS of a tone language. Nineteen- and…

This theoretical article aims to create a conceptual framework for future research on digital methods for assessing cognition in children through estimating shared intentionality, different from assessing through behavioral markers. It shows the new assessing paradigm based directly on the evaluation of parent-child interaction exchanges…

The present study contributes to the field of bilingual and trilingual language acquisition by analysing four multilingual families. In each family, at least one parent is bilingual. Following research questions will be addressed: (A) "How relevant are the (amount of) input and the (kind of) parental language strategies for language…

This study, using longitudinal data from the South African Birth to Twenty Plus study, assessed associations between early childcare quality in the home between six months and two years, household SES and cognitive development at age 5. Childcare quality was assessed using measures of maternal responsiveness and cognitive stimulation. Cognitive…

Epigenetic regulation of the placental glucocorticoid receptor gene ("NR3C1") was investigated as a mechanism underlying links between maternal smoking during pregnancy (MSDP) and infant neurobehavior in 45 mother-infant pairs (49% MSDP-exposed; 52% minorities; ages 18-35). The Neonatal Intensive Care Unit (NICU) Network Neurobehavioral…

Adverse experiences superseding a child's capacity to sustain regulation of emotion and adaptive function are theorized to constitute "toxic stressors" when they induce a deleterious biological response within an individual. We ascertained presumptive parameters of toxic stress among 164 low-income infants and toddlers (ages 4-48 months)…

There is preliminary evidence that infant siblings of children with Autism Spectrum Disorder (ASD) have an atypical pattern of cry, characterized by higher fundamental frequency and increased dysphonation. This prospective study collected multiple cry samples of 12-month old siblings of children with ASD (n = 22, "high-risk" group) and…

Language provides rich social information about its speakers. For instance, adults and children make inferences about a speaker's social identity, geographic origins, and group membership based on her language and accent. Although infants prefer speakers of familiar languages (Kinzler, Dupoux, & Spelke, 2007), little is known about the…
