Purpose: This study examines object permanence development in infants with motor delays (MD) compared with infants with typical development (TD) and in relation to sitting skill. Methods: Fifty-six infants with MD (mean age = 10 months) and 36 with TD (mean age = 5.7 months) were assessed at baseline and then at 1.5, 3, and 6 months postbaseline.…

Purpose: The purpose of this study is to characterize parameters used for frequency-following response (FFR) acquisition in children up to 24 months of age through a systematic review. Method: The study was registered in PROSPERO and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses' recommendations. Search was…

Statistical learning refers to the ability to extract the statistical relations embedded in a sequence, and it plays a crucial role in the development of communicative and social skills that are impacted in the Autism Spectrum Disorder (ASD). Here, we investigated the relationship between infants' SL ability and autistic traits in their parents.…

In four experiments, we tested whether 20-month-old infants are sensitive to violations of procedural impartiality. Participants were shown videos in which help was provided in two different ways. A main character provided help to two other agents either impartially, by helping them at the same time, or in a biased way, by helping one agent almost…

In everyday life, children hear but also often see their caregiver talking. Children build on this correspondence to resolve auditory uncertainties and decipher words from the speech input. As they hear the name of an object, 18- to 30-month-olds form a representation that permits word recognition in either the auditory (i.e. acoustic form of the…

The account that word learning starts in earnest during the second year of life, when infants have mastered the disambiguation skills, has recently been challenged by evidence that infants during the first year already know many common words. The preliminary ability to rapidly map and disambiguate linguistic labels was tested in Italian-speaking…

Words that describe sensory perception give insight into how language mediates human experience, and the acquisition of these words is one way to examine how we learn to categorize and communicate sensation. We examine the differential predictions of the typological prevalence hypothesis and embodiment hypothesis regarding the acquisition of…

Early childhood providers care for infants and toddlers with developmental delays and special needs in their programs and classrooms. This study addressed the problem that there is insufficient professional development (PD) training for early childhood providers working with infants and toddlers with special needs in inclusive settings. The…

Habituation and dishabituation are the most prevalent measures of infant cognitive functioning, and they have reliably been shown to predict later cognitive outcomes. Yet, the exact mechanisms underlying infant habituation and dishabituation are still unclear. To investigate them, we tested 106 8-month-old infants on a classic habituation task and…

Calls to bring more equity into science education research (McWayne and Melzi, 2023) are most notable for early childhood. We know very little about the teaching of science to infants and toddlers, yet this is where science education begins. To address the dearth in research, we undertook an in-depth intervention study in an Australian early…

The objective of this study was to evaluate the motor, cognitive and language development of babies living in two institutional contexts. Seventy babies participated in the study: 35 from prisons and 35 from shelters. Thirty-five mothers of hospitalized babies and 10 caregivers of hospitalized babies also participated in this study. The…

The purpose of this study was to improve the conceptual development of an infant through age-appropriate picture books, as well as potentially reveal the effects of such books for developing concepts in children's literature. Study participants used the changing criterion design from single-case research models that consisted of 1 infant and 3…

Language is the basis of human communication and is the most important key to complete mental development and thinking. Therefore, children must learn to communicate using appropriate language. For this to happen, the development of language in the child must be understood as a biological process, complete with internal laws and with marked stages…

Many bilingual infants attend early childhood education centres (ECEC) with their monolingual peers. However, recent evidence reveals that bilingual infants vocalise significantly less than monolingual infants in ECEC settings (Zheng et al. 2023) [Effects of Multilingualism on Australian Infants' Language Environments in Early Childhood Education…

Development of professional competencies is a key outcome of undergraduate programs preparing practitioners to work with infants and toddlers. Competencies for working with young children were examined among 1300 undergraduate students at 12 universities. Students completed a series of online questionnaires indicating their knowledge, beliefs, and…
