Negation is a cornerstone of human language and one of the few universals found in all languages. Without negation, neither categorization nor efficient communication would be possible. Languages, however, differ remarkably in how they express negation. It is yet widely unknown how the way negation is marked influences the acquisition process of…

Infants as young as 2 months can integrate audio and visual aspects of speech articulation. A shift of attention from the eyes towards the mouth of talking faces occurs around 6 months of age in monolingual infants. However, it is unknown whether this pattern of attention during audiovisual speech processing is influenced by speech and language…

Bilingual and monolingual infants differ in how they process linguistic aspects of the speech signal. But do they also differ in how they process non-linguistic aspects of speech, such as who is talking? Here, we addressed this question by testing Canadian monolingual and bilingual 9-month-olds on their ability to learn to identify native…

The influence of motor knowledge on speech perception is well established, but the functional role of the motor system is still poorly understood. The present study explores the hypothesis that speech production abilities may help infants discover phonetic categories in the speech stream, in spite of coarticulation effects. To this aim, we…

Unstructured outdoor play is important for children's development. The present study examined infants' and toddlers' physical and social unstructured outdoor play behaviors within childcare centers. Children's outdoor play behaviors were video recorded at two centers (A&B) and assessed using a modified version of the Observational System for…

Purpose: Despite advances in cochlear implant and hearing aid technology, many children with hearing loss continue to exhibit poorer language skills than their hearing peers. This randomized pilot trial tested the effects of a parent-implemented communication treatment targeting prelinguistic communication skills in infants and toddlers with…

Background: While delays in cognitive development are detectable during early development in Down syndrome, the neuropsychological and biomedical underpinnings of cognitive skill acquisition in this population remain poorly understood. Method: To explore this issue, 38 infants with Down syndrome [mean chronological age = 9.65 months; SD = 3.64]…

In this article, I explore two epistemologies for theorizing infancy and treating autism--infant and child psychoanalysis expounded by Frances Tustin and colleagues and developmental psychology and developmental neuroscience. I address two main issues: (a) how early psychoanalytic insights informed empirical developments and theoretical…

Infants begin to understand some of the meanings of the adjective "good" at around thirteen months, but it is not clear when they start to map it to concepts in the moral domain. We investigated infants' and toddlers' knowledge of "good" in the domains of help and fairness. Participants at 20 and 30 months were shown computer…

Extracting the statistical regularities present in the environment is a central learning mechanism in infancy. For instance, infants are able to learn the associations between simultaneously or successively presented visual objects (Fiser & Aslin, 2002; Kirkham, Slemmer & Johnson, 2002). The present study extends these results by…

Australia's National Quality Framework identifies responsibilities for early childhood educators who work with infants to plan for and assess their learning. Educators are urged to be "responsive to children's ideas and play" and to "assess, anticipate and extend children's learning". Responsiveness in relation to infants is…

The study evaluated the relationship between maternal anxiety, depression and parenting stress, and maternal mind-mindedness, styles of interaction, and mother-infant emotion regulation. At infant age 3 months, EPDS, STAI, and PSI-SF were administered to 73 mothers to respectively assess depression, anxiety, and parenting stress; mother-infant…

Community health workers possess valuable insight into the experiences of South Africa's children and caregivers. However, their knowledge is often overlooked in efforts to understand local realities, inform interventions, and develop relevant policies. This study aimed to explore community health workers' perspectives of the first 1000 days of…

An expansive view of care is vital to understanding children's sense-making of their care experiences in early childhood education. Yet, scant literature explores how toddlers enact and express understandings of care in their play with objects and others. This article identifies play situations where toddlers enact and express understandings, and…

Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…
