This report presents key statistics and trends for teenage mothers and their babies in Australia. Teenage mothers and their babies are more likely to experience broader disadvantage, have antenatal risk factors and have poorer maternal and baby outcomes during and after birth, than older mothers and their babies. In Australia, the rate of teenage…

Babies think differently than adults, and understanding how they think can help us see their explosive brain growth in everyday behavior. Infants learn language faster than adults do, use statistics to understand how the world works, and even reason about the minds of others. But these achievements can be hidden by their poor self-regulatory…

Two experiments examined whether 4-month-olds (n = 120) who were induced to assign two objects to different categories would then be able to take advantage of these contrastive categorical encodings to individuate and track the objects. In each experiment, infants first watched functional demonstrations of two tools, a masher and tongs (Experiment…

We tested 4-6- and 10-12-month-old infants to investigate whether the often-reported decline in infant sensitivity to other-race faces may reflect responsiveness to static or dynamic/silent faces rather than a general process of perceptual narrowing. Across three experiments, we tested discrimination of either dynamic own-race or other-race faces…

This study examined how timing (i.e., relative maturity) and rate (i.e., how quickly infants attain proficiency) of A-not-B performance were related to changes in brain activity from age 6 to 12 months. A-not-B performance and resting EEG (electroencephalography) were measured monthly from age 6 to 12 months in 28 infants and were modeled using…

In languages with evidential marking, utterances consist of an informational content and a specification of the mode of access to that information. In this first longitudinal study investigating the acquisition of the Turkish evidential marker "-mIs" in naturalistic child-caregiver interactions, we examined six children between 8 and 36…

To probably overcome the challenge of learning two languages at the same time, infants raised in a bilingual environment pay more attention to the mouth of talking faces than same-age monolinguals. Here we examined the consequences of such preference for monolingual and bilingual infants' ability to perceive nonspeech information coming from the…

Adults and toddlers systematically associate pseudowords such as "bouba" and "kiki" with round and spiky shapes, respectively, a sound symbolic phenomenon known as the "bouba-kiki effect." To date, whether this sound symbolic effect is a property of the infant brain present at birth or is a learned aspect of language…

The mutual exclusivity (ME) assumption is proposed to facilitate early word learning by guiding infants to map novel words to novel referents. This study assessed the emergence and use of ME to both disambiguate and retain the meanings of novel words across development in 18-month-old monolingual and bilingual children (Experiment 1; N = 58), and…

Many studies have documented influences of maternal responsiveness on cognitive and language development. Given the bidirectionality of interactions in caregiver-infant dyads, it is important to understand how infant behavior elicits variable responses. Prior studies have shown that mothers respond differentially to features of prelinguistic…

Although there have been calls in the early childhood field for effective approaches to preparing the workforce to support optimal early child development, there is a gap in understanding how different types of professional development predict teachers' beliefs about children and their self-reported classroom practices. Using the National Survey…

This experiment tests the age at which left-to-right spatial associations found in infancy shift to culture-specific spatial biases in later childhood, for both numerical and non-numerical information. Children ages 1-5 years (N = 320) were tested within an eye-tracking paradigm which required passive viewing of a video portraying a spatial…

This research study aimed to explore the experiences of caregivers of children through the early hearing detection and intervention (EHDI) process in the public health care sector in South Africa. A qualitative research design was employed. Semistructured interviews were conducted with 8 caregivers from 3 different levels of service delivery in…

The aim of this cross-sectional study was to investigate the discriminant validity of the Persian version of Alberta Language Development Questionnaire (ALDeQ) in Turkish-Persian bilingual children, aged 75 months with 19 months of exposure to Persian, on average. The study sample included the parents of 22 bilingual children with language…

This prospective longitudinal study examined how maternal prenatal substance use disorder (SUD) and early mother-infant interaction quality are associated with child social cognition (emotion recognition and mentalization) at school age. A sample of 52 poly-substance-using mothers receiving early interventions and 50 non-users, along with their…
