Mirror self-recognition (MSR) is considered to be the benchmark of objective self-awareness--the ability to think about oneself. Cross-cultural research showed that there are systematic differences in toddlers' MSR abilities between 18 and 24 months. Understanding whether these differences result from systematic variation in early social…

This paper discusses collaborative research between academics and practitioners to enhance the level of play engagement in nine groups of toddlers in The Netherlands. Researchers and pedagogic counsellors designed a structured experiment to test the effects of four pedagogical strategies: confronting the children with a rearranged activity corner;…

Engaging in prosocial behavior is costly. By selectively directing prosocial behavior toward individuals with a high probability of reciprocating, we are able to offset these potential costs and maintain a sustainable prosocial system. Often, we determine whether an individual will make a good prosocial partner through the observation of their…

PlayWisely is a novel approach to early learning designed to target the positive development of a wide range of cognitive and physical/motor abilities by stimulating the rapidly developing brain of very young children (from 4 months to 3 years of age). The current pilot study represents a first step toward providing an evidence base for the…

For infants and young children who are identified as deaf or hard of hearing (DHH), best practice principles indicate the provision of family-centered early intervention (FCEI). However, factors such as geographical inaccessibility and workforce shortages can limit families' access to FCEI in their local area. One strategy for overcoming these…

Children's early interactions with adults during the first three years of life are instrumental in the development of their language, cognitive, and social skills, which in turn are strongly related to later achievement and success into adolescence. Early childhood professionals working with infants and toddlers need to understand children's…

This dissertation investigates when and how children figure out the force of modals, that is, when and how they learn that "can/might" express possibility, whereas must/have to express necessity. Learning modal force raises a logical "Subset Problem": given that necessity entails possibility, what prevents learners from…

Identifying early risk factors for the development of social anxiety symptoms has important translational implications. Accurately identifying which children are at the highest risk is of critical importance, especially if we can identify risk early in development. We examined continued risk for social anxiety symptoms at the transition to…

The study adopts a naturalistic perspective, looking at the relationship between socio-economic status (SES), activities and variation sets in child-directed speech (CDS) to Spanish-speaking Argentinian toddlers. It aims to determine the effect of SES and type of activity on the proportion of words and utterances in variation sets and on the…

The present study examined what kind of parenting best supports toddlers' self-control in the context of poverty. Parents and toddlers (52% female; M[subscript age] = 2.60 years) in 117 families (35% White, 25% Black, 22% Latinx, 15% Multiracial, and 3% Asian; M family income = $1,845/month) engaged in structured interaction tasks, and toddlers…

The current study investigated longitudinal associations between parent-rated temperament, observed exuberance and accelerometer activity level at 18-months and symptoms of ASD and ADHD at 36-months in a sample of 54 children at elevated likelihood for ASD. For the specific parent-rated temperament scales, most observed significant associations…

Preliminary findings from a follow-up study of 33 children, assessed for their socioemotional development from 18 months of age, are presented. At 77 months, they were evaluated again in a laboratory context, recording on video a situation of discussion of a conflict with the caregiver and then coding these videos using the CIB instrument.…

The ability to regulate one's emotions and behaviors is essential for adaptive functioning in society. We investigated whether parental mind-mindedness--parents' tendency to treat their children as mental agents--in infancy and toddlerhood predicts school-age children's self-regulation. The sample consisted of 125 mostly Dutch and White families.…

Research Findings: In this study, we tested whether it is possible to reliably evaluate the quality of interactions between early childhood educators and children using a thin-slice coding approach. Ninety-seven early childhood educators were videotaped for two five-minute intervals: one mealtime observation and one standardized activity. Videos…

Real-time attention coordination in parent-toddler dyads is often studied in tightly controlled laboratory settings. These studies have demonstrated the importance of joint attention in scaffolding the development of attention and the types of dyadic behaviors that support early language learning. Little is known about how often these behaviors…
