The aim of this study is to define the changes within the social dimension of the functional status of women and their partners in the months following the birth of their child. A total of 90 participants were included in the study (45 women and 45 partners). Data were collected in two steps via face-to-face interviews. The first step involved…

Fifteen-month-olds have difficulty detecting differences between novel words differing in a single vowel. Previous work showed that Australian English (AusE) infants habituated to the word-object pair DEET detected an auditory switch to DIT and DOOT in Canadian English (CanE) but not in their native AusE (Escudero et al., 2014). The authors…

Although preterm infants are at risk for social deficits, interventions to improve mother-infant interaction in the neonatal intensive care unit (NICU) are not part of standard care (SC). Study participants were a subset from a randomized controlled trial of a new intervention for premature infants, the Family Nurture Intervention (FNI), designed…

Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

Purpose: The vocalizations of young infants often sound nasalized, suggesting that the velopharynx is open during the 1st few months of life. Whereas acoustic and perceptual studies seemed to support the idea that the velopharynx closes for vocalization by about 4 months of age, an aeromechanical study contradicted this (Thom, Hoit, Hixon, &…

How long does it take for a newborn to recognize an object? Adults can recognize objects rapidly, but measuring object recognition speed in newborns has not previously been possible. Here we introduce an automated controlled-rearing method for measuring the speed of newborn object recognition in controlled visual worlds. We raised newborn chicks…

Adults automatically infer a person's social disposition and future behavior based on the many properties they observe about how they look and sound. The goal of the current study is to explore the developmental origins of this bias. We tested whether 12-month-old infants automatically infer a character's social disposition (e.g., whether they are…

Prospective motor control, a key element of action planning, is the ability to adjust one's actions with respect to task demands and action goals in an anticipatory manner. The current study investigates whether 14-month-olds can prospectively control their reaching actions based on the difficulty of the subsequent action. We used a reach-to-place…

Purpose: This study investigates the development of phase locking and frequency representation in infants using the frequency-following response to consonant-vowel syllables. Method: The frequency-following response was recorded in 56 infants and 15 young adults to 2 speech syllables (/ba/ and /ga/), which were presented in randomized order to the…

Infants' perception of faces becomes attuned to the environment during the first year of life. However, the mechanisms that underpin perceptual narrowing for faces are only poorly understood. Considering the developmental similarities seen in perceptual narrowing for faces and speech and the role that statistical learning has been shown to play…

This observational study examined the Iranian mothers' interaction with their typically developing children aged 13-18 months during free play at home (n = 40). The first aim was to determine the main type of Iranian maternal verbal responsiveness. Another aim was to investigate the impact of concurrent prediction of maternal verbal responsiveness…

Early intervention (EI) practitioners are expected to coach families in embedding intervention strategies for their infant or toddler within their everyday routines. EI practitioners use authentic assessment approaches (i.e., observation and discussion) to gain a real-life picture of what the child is good at and what can be difficult to identify…

The literature on infant and toddler screen time has been built on two traditions--cognitive models of learning and sociocultural models of learning. Cognitive studies have cautioned against the use of screen time for young children because clinical research has not shown children can learn as effectively from screens as they do from human…

Early childhood educators are encouraged to read with infants, yet little is known about the educator-infant book-focused interactions that occur in Early Childhood Education and Care (ECEC) centres. This study provides a systematic linguistic analysis of the naturally occurring interactions between one focal child Charlie (aged 21 months and…

Infancy (0-3 years) represents a unique time for language learning. Previous research shows that infants' second language (L2) learning advances rapidly in early education centers, through a research-based method and curriculum delivered by native-speaking language tutors. Here we test the potential of this method for broad application, through an…
