Purpose: The aim of this study was to investigate infants' listening preference for emotional prosodies in spoken words and identify their acoustic correlates. Method: Forty-six 3- to-12-month-old infants (M[subscript age] = 7.6 months) completed a central fixation (or look-to-listen) paradigm in which four emotional prosodies (happy, sad, angry,…

Search filters are used to find evidence on specific subjects. Performance of filters can be varied and may need adapting to meet the needs of research topics. There are limited geographic search filters available, and only one pertaining to low- and middle-income countries (LMICs). When searching for literature on preterm birth prevention and…

Purpose: Current models of speech development argue for an early link between speech production and perception in infants. Recent data show that young infants (at 4-6 months) preferentially attend to speech sounds (vowels) with infant vocal properties compared to those with adult vocal properties, suggesting the presence of special "memory…

This qualitative descriptive study was designed to answer the following questions: How do infant/toddler teachers (ITTs) enter the infant/toddler workforce? What motivates teachers to work in the infant/toddler workforce? What recruitment strategies are identified by experienced ITTs? What retention strategies are identified by experienced ITTs?…

The purpose of this research was to organize a cross-cultural adaptation study and analyze the reproducibility and test-retest reliability of the Infant Sensory Profile 2 (ISP2Br) to Brazilian babies. It was hypothesized that the instrument would be validated for use with Brazilian babies. The English language version of the profile was translated…

Purpose: Limited quantitative data exist regarding growth of the velopharynx within the first 2 years of life. The purpose of this study was to (a) quantify changes in velopharyngeal structures due to growth during the first 2 years of life, (b) examine the impact of sex and race within this age range, and (c) provide normative measures for…

Medical personnel play a critical role in caregiver safe infant sleep education. However, training outcomes in the safe infant sleep training literature have been mixed. Promising approaches that warrant further investigation are the use of behavioral skills training and pyramidal training. The current study consisted of two experiments.…

Purpose: This case series documents developmental changes over time and in response to a novel intervention, Sitting Together and Reaching to Play (START-Play), in children with early-life seizures. Methods: Thirteen children with early-life seizures were included from a subset of participants in the START-Play multisite, randomized controlled…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

Caregivers play an outsized role in shaping early life experiences and development, but we often lack mechanistic insight into "how" exactly caregiver behavior scaffolds the neurodevelopment of specific learning processes. Here, we capitalized on the fact that caregivers differ in how predictable their behavior is to ask if infants'…

The foremost index of caregiving quality is child attachment, as supported by attachment theory. Research supports the relevance of early parenting interventions in improving child outcomes in attachment quality to promote public health because of their long-term effects on mental health and functioning. This study aimed at evaluating the impact…

Background: There is growing interest in research understanding the individual-specific predictors of child callous-unemotional (CU) traits, particularly in early childhood. Objective: This study reviewed evidence from studies that investigated the relationship between early child temperament factors (between 0 and 3 years) and CU traits in…

The 'schoolification' of early childhood education and care programs, seen as readying children for formalised schooling, has had an impact on the education of younger and younger age groups. While the focus of past research has mainly focused on 4-5-year-old children, this study shifts the focus to 2-3-year-old children and the literacy focus of…

Infants, toddlers, and two-year-olds with disabilities or developmental delays often participate in center-based childcare. Just like other care and education settings, childcare for very young children should provide high-quality inclusion. To date, minimal research has been conducted on practitioner perspectives about inclusion in childcare for…

This paper presents the development of a participatory digital platform designed to promote nature-based experiences for children aged 0 to 3 years. The project responds to the growing reduction of young children's opportunities to engage with nature in their daily lives, despite the critical role such experiences play in early development.…
