Infants' ability to perform visual short-term memory (VSTM) tasks develops rapidly between 6 and 8 months. Here we tested the hypothesis that infants' VSTM performance is influenced by their ability to individuate simultaneously presented objects. We used a "one-shot change detection task" to ask whether 6-month-old infants (N = 47)…

The objective of this study was to examine the links between prosodic features of paternal Infant-Directed Speech (IDS) and child characteristics. Pitch variability measures were extracted from the speech samples of 50 fathers during unstructured play with their two-year-old children. Evidence for a link between child receptive language ability…

The onset of intentional communication in children's first year of life represents a major milestone in human cognitive development. Similarly, it is well established that our closest living relatives, the great apes, communicate with signals characterized by at least first-order intentionality. Despite the well-documented influence of…

Infants appear to progress from universal to language-specific event perception. In Japanese, two different verbs describe a person crossing a "bounded ground" (e.g., street) versus an unbounded ground (e.g., field) while in English, the same verb -- "crossing" -- describes both events. Interestingly, Japanese "and"…

There is clear evidence that early mathematical development sets the foundation for success in later mathematics learning; however, there is little research which considers mathematics education for children under three years of age. This paper provides a snapshot of findings from a national survey of early childhood educators conducted as part of…

This study compares the mental-state talk of infant educators in Australia and China in order to determine the nuanced differences in the ways that they use this talk with the infants in their room. Participants are 44 native English-speaking Australian educators from centres in Sydney, Australia and 30 native Chinese-speaking infant educators…

The development of cognitive and motor skills early in life is essential for a child's global development and learning, which in turn influences later health and well-being. This cross-sectional study aimed to determine the associations between sociodemographic factors and nutritional factors with cognitive and motor delays in infants aged 6-12…

Background: Given the importance of adaptive behaviour (AB) for the identification of intellectual disability and the design of intervention plans for people with Down syndrome (DS), this cross-sectional study explored AB in infants with DS, compared to infants with typical development (TD). Method: we evaluated 60 infants (10-36 months) with…

Infants attend daycare at an early age, which raises questions about children's sensitivity to the childcare environment and the role of different temperamental traits in their development in the early years. In a two-year longitudinal study with parent- and caregiver-reported data for Dutch children at the age of 1 and 2 years (120 children from…

Minnesota Statutes, section 125A.125, requires the Minnesota Department of Education (MDE) to annually report on the number of children experiencing homelessness served by the Part C Infant and Toddler Intervention system. The current report covers the 2020-21 school year. Data for this report came from the Minnesota Automated Reporting Student…

The focus of the present longitudinal study, to examine mother-infant interaction during the administration of immunizations at 2 and 6?months of age, used hidden Markov modelling, a time series approach that produces latent states to describe how mothers and infants work together to bring the infant to a soothed state. Results revealed a…

Research Findings: Multiple factors likely influence the language development of young children growing up in low-income homes, potentially including stressors experienced by parents. Here, we ask: (1) What is the association between stress (i.e., economic hardship and parenting stress) and toddlers' language development? and (2) Does number of…

This paper examines the acquisition of demonstratives (e.g., "that," "there") from a cross-linguistic perspective. Although demonstratives are often said to play a crucial role in L1 acquisition, there is little systematic research on this topic. Using extensive corpus data of spontaneous child speech, the paper investigates…

This article describes the professional development program, Baby Playspace Learning (BPL), and evaluates its capacity to build close relationships between educators, parents, their infants and infant peers during the morning transitions in ECEC settings. Using a pre-post design, video recordings of 20 (10 pre and 10 post) morning transitions were…

This study reports on the development of new motor and behavioural indicators for recognizing symbolic acts among infants. Following five infants between the ages of 6 and 18 months and their ability to use an object in novel way yielded four levels of action, based on the number of objects and actions combined in each symbolic act. Employing…
