There is a growing consensus in research that children's numerical competence starts to develop at a very early age. However, there are few tools for screening the development of early numerical competence and thereby making this development researchable. One obstacle in designing such tools is that verbal utterances cannot be used as the primary…

This study investigated the associations between infant frontal EEG power (5 month), infant visual attention (10 month), and toddler executive functioning (EF; 24 month), extending previous research predominantly conducted with school-aged children. Data were collected from 410 typically developing children (51% female; 78% White, non-Hispanic)…

This study examined patterns of verbal responsiveness in parents of toddlers (M[subscript age] = 20 months) later identified with autism (n = 121), developmental delay (n = 46), or typical development (n = 44) during an hourlong home observation. Parent verbal responsiveness (PVR) was compared using MANOVA across groups and by child expressive…

There has been a major international focus on the education and care of toddlers. To date, empirical studies on adults' interactions in play with toddlers have focussed on the proximity of teachers, teachers' affective responses, and joint attention between adults and children in play. However, less attention has been given to the role of two…

The 2020 Dietary Guidelines for Americans now include recommendations for infants and toddlers. Extension educators can use these expanded guidelines to provide feeding recommendations for caregivers of infants/toddlers. The purpose of this study was to explore 1) the infant and toddler feeding topics that Extension educators discuss with…

Sensory features are included in the diagnostic criteria of autism spectrum disorder, and sensory responsiveness may produce "cascading effects" on later development. However, the relation between early sensory profiles and later skills has yet to be defined. This study aims to characterize sensory subgroups in 116 toddlers at elevated…

Screening for autism in childhood has been advocated as a part of standard care. Challenges exist with screening implementation and performance of screening tools in clinical practice. This study aimed to examine the validity and feasibility of using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) for screening…

Musical communication between adults and children is a widely studied phenomenon in the field of music education and psychology. In the research carried out to date, a variety of methodological designs have been used, based mainly on the perceptions of adults, to investigate the different aspects of these musical interactions. Thus, there is…

The purpose of the current study was to revisit a controversial topic: whether frequencies of phonological consonant and vowel classes differ in speech directed to children and to adults. In addition, the current study investigated whether the frequency of phonological consonant and vowel classes changes with children's increasing chronological…

This study examined the feasibility of implementing the Screening Tool for Autism in Toddlers, an interactive Level-2 screen for autism spectrum disorder, within Part C Early Intervention settings. Participants included 69 Early Intervention providers (M age = 43.3 years, 93.7% females, 92.4% Whites) from nine programs who attended a one-day…

Autistic people are often portrayed as lacking empathy. Yet they are not indifferent to others' feelings. To advance our understanding of the early development of empathy in autistic children, this longitudinal study followed the development of four empathy abilities: emotion contagion, attention to others, emotion acknowledgment, and prosocial…

During infancy and toddlerhood, parents show large individual differences in the extent to which they are able to tailor their parenting behaviors to their children's swiftly changing developmental needs. The first aim of our study was, therefore, to distinguish parenting profiles at three time points during infancy and toddlerhood (i.e., 5, 10,…

Despite the relative increase in early care and education (ECE) investment over recent decades, access to infant and toddler care continues to be a hurdle for countless families across the nation. While access is a multifaceted issue, main contributors include a lack of available slots and the high cost of providing care to infants and toddlers.…

Forty-eight toddlers participated in a word-learning task to assess gesture input on mapping nonce words to unfamiliar objects. Receptive fast mapping and expressive naming for target object-word pairs were tested in three conditions -- with a point, with a shape gesture, and in a no-gesture, word-only condition. No statistically significant…

Anticipating the learning consequences of actions is crucial to plan efficient information seeking. Such a capacity is needed for learners to determine which actions are most likely to result in learning. Here, we tested the early ontogeny of the human capacity to anticipate the amount of learning gained from seeing. In study 1, we tested infants'…
