The speech register that adults especially caregivers use when interacting with infants and toddlers, that is, infant-directed speech (IDS) or baby talk, has been reported to facilitate language development throughout the early years. However, the neural mechanisms as well as why IDS results in such a developmental faciliatory effect remain to be…

This study investigated the extent to which sensory responsivity in infancy contributes to adaptive behavior development among toddlers at high-familial likelihood for autism. Prospective, longitudinal data were analyzed for 218 children, 58 of whom received an autism diagnosis. Results indicated that sensory profiles at age one year…

This study presents data on the effectiveness of participatory training, called 'Improvement Groups', voluntarily adopted in four nurseries in Northern Italy to prevent episodes of violence by staff toward children. The interventions provided for the representation of problematic cases, experienced by participants, relating to factors of work…

Perspective taking and cognitive flexibility are important abilities for navigating our everyday lives. In this longitudinal study with 108 children (61 girls, mostly White), we investigated the developmental relation between Level 1 perspective taking at 27 months of age and Level 2 perspective taking at 52 months of age as well as relations to…

The home environment is a significant factor that greatly influences the motor development of children. This study aims to examine the cultural adaptation validity and reliability of the Affordances in the Home Environment for Motor Development (AHEMD-SR) for Turkish children aged 18--42 months. The study included 103 Turkish children (mean age =…

Children actively and selectively transmit information to others based on the type of information and the context during learning. Four- to 7-year-old children preferentially transmit generalizable information in teaching-like contexts. Although 2-year-old children are able to distinguish between generalizable and non-generalizable information, it…

While gender differences in mathematical competencies favoring boys are well researched for school and late Kindergarten age, much less is known about their earlier development. Using data from the NEPS Newborn Cohort study, this paper focuses on 4 year-old children and the effects of the numerical and literacy stimulation during mother-child…

Mature social evaluations privilege agents' intentions over the outcomes of their actions, but young children often privilege outcomes over intentions in verbal tasks probing their social evaluations. In three experiments (N = 118), we probed the development of intention-based social evaluation and mental state reasoning using nonverbal methods…

Parents play an important role in socializing children's emotion understanding. Previous research shows that parents emphasize different aspects of emotion contexts depending on the discrete emotion. However, there is limited research on how parents and children discuss self-conscious emotions, such as embarrassment, guilt, and shame, and what…

Discovering the meaning of novel communicative cues is challenging and amounts to navigating an unbounded hypothesis space. Several theories posit that this problem can be simplified by relying on positive expectations about the cognitive utility of communicated information. These theories imply that learners should assume that novel communicative…

STEM is not just about learning four discrete subject-specific content areas (McClure et al., 2017), but also an approach of higher order thinking (i.e., the ability to think critically, logically, and creatively, and solve problems; Baharin et al., 2018). In this article, the authors use STEM learning to describe children's learning about STEM,…

During the COVID-19 global pandemic, early intervention (EI) practitioners experienced an unexpected shift to providing tele-intervention services to support children and families using virtual platforms. Because this shift occurred across the field, it is important to understand the perspectives of those who experienced it under exceptional…

Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Purpose: The Language ENvironment Analysis (LENA) technology uses automated speech processing (ASP) algorithms to estimate counts such as total adult words and child vocalizations, which helps understand children's early language environment. This ASP has been validated in North American English and other languages in predominantly monolingual…

When children are aged around 2 years, many of the early foundations of mathematical skills are developing. Understanding this is important to shed light on theories of mathematical development. Nevertheless, little research has investigated 2-year-olds' early mathematical abilities, with most research focussing on either infants (aged 0-1 years)…
