Infants who receive better counting input at home tend to become toddlers with better number knowledge in preschool. However, for many children, in-person counting experience is not always available, despite educational media becoming increasingly prevalent. Might virtual counting experience benefit the young mind? Using a novel online looking…

Recent behavior analytic studies have examined behavioral skills training to teach adults to arrange safe infant sleeping environments. These studies were conducted in an analogue environment and with all training components delivered by an expert staff trainer. The purpose of the current study was to replicate and extend this literature by…

Sustained attention (SA) is an endogenous form of attention that emerges in infancy and reflects cognitive engagement and processing. SA is critical for learning and has been measured using different methods during screen-based and interactive contexts involving social and nonsocial stimuli. How SA differs by measurement method, context, and…

With the explosive growth in time spent on YouTube by babies and toddlers, it's important to analyze what they're watching on YouTube. Indexes that evaluate the contents of YouTube channels for infants and toddlers have been developed, but since those were evaluation-based indexes of educators and parents, it is difficult to find out what content…

This doctoral study examined the function of baby massage in supporting early infant-carer attachment relationships among families facing stressful life experiences. It was designed in response to Bennett, Underdown and Barlow's [Bennett, C., A. Underdown, and J. Barlow. 2013. "Massage for Promoting Mental and Physical Health in Typically…

Grounded in Froebelian Principles, infused with Bakhtin's Dialogism, this paper draws from a larger ethnographic doctoral study to illuminate the way seven Early Childhood Educators based in England reflect on, and reconceptualise the voices of babies through engagement with a new reflective model, Video Interaction Dialogue (VID). Through a…

Early intervention supports infants and toddlers with confirmed or suspected autism spectrum disorder (ASD) in achieving optimal outcomes, and caregiver-implemented NDBIs are recommended as a developmentally appropriate intervention approach for very young children and their families. Research highlights discrepancies between early…

We compared maternal speech in interactions of mothers with their firstborn dizygotic twin and singleton infants. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to the 6th month. Continuous micro-analysis revealed that there are more quantitative and qualitative…

Early object name learning is often conceptualized as a problem of mapping heard names to referents. However, infants do not hear object names as discrete events but rather in extended interactions organized around goal-directed actions on objects. The present study examined the statistical structure of the "nonlinguistic" events that…

Why do infants learn some words earlier than others? Many theories of early word learning focus on explaining how infants map labels onto concrete objects. However, words that are more abstract than object nouns, such as "uh-oh," "hi," "more," "up," and "all-gone," are typically among the first to…

Infant-directed speech (IDS) is characterized by a range of register-typical characteristics. Many of those can be objectively measured, such as acoustic-prosodic and structural-linguistic modifications. Perceived vocal affect, however, is a socio-emotional IDS characteristic and is subjectively assessed. Vocal affect goes beyond acoustic-prosodic…

There are two broad views of children's theory of mind. The mentalist view is that it emerges in infancy and is possibly innate. The minimalist view is that it emerges more gradually in childhood and is heavily dependent on learning. According to minimalism, children initially understand behaviors rather than mental states, and they are assisted…

Undertaking infant-toddler practicum during initial teacher education is critical to ensuring preservice teachers (PSTs) are well prepared for their future role as early childhood teachers. PSTs, however, can face challenges in infant-toddler practicum given the demands of this unique teaching and learning context. A knowledgeable, experienced…

Using a habituation paradigm with a three-switch design, the present study investigated whether 20-month-old French-learning infants use noun and verb morphosyntactic cues to learn novel words in dynamic events differentially when both the agent and the action interpretations are possible. Of particular interest was whether infants' initial…

Successful language learning in bilinguals requires the differentiation of two language systems. The capacity to discriminate rhythmically close languages has been reported in 4-month-olds using auditory-only stimuli. This research offers a novel perspective on early language discrimination using audiovisual material. Monolingual and bilingual…
