This article compares the communicative intentions observed in the speech addressed to children of 1;1 and 1;6 years old from three cultural communities: the Netherlands, rural Mozambique, and urban Mozambique. These communities represent two prototypical learning environments and a third hybrid: Western, urban, middle-class families; non-Western,…

While the rates of teen childbearing have declined in the United States, adolescents who become pregnant and decide to bear and rear their babies are often from low-income, highly stressed families and communities. This article will describe the psychosocial problems of pregnant urban teens and how exposure to interpersonal trauma and current…

Taiwan has over the past three decades been experiencing demographic changes that may pose important concerns for children's quality of life. This study examines the relationships and potential pathways between family structure transitions and early childhood development. Our analysis is based on 19,499 children from the 2005 birth cohort who…

Within the United States a significant population of foster care infants and toddlers access early special education services under the parameters of the "Individuals with Disabilities Education Act" (IDEA)-Part C (United States Congress 2004). A dearth of literature exists about special education interventionists' services for this…

What do preschool teachers know about infant/toddler care and education? The answer to the question in the title is "Lots!" "if" they are fans of Lilian Katz. The author would not have said that before she sat down to read the new book Lilian wrote with her son Stephen. It's called "Intellectual Emergencies." It starts out with 12 of Lilian's…

Explanations of variability in long-term recall typically appeal to encoding and/or retrieval processes. However, for well over a century, it has been apparent that for memory traces to be stored successfully, they must undergo a post-encoding process of stabilization and integration. Variability in post-encoding processes is thus a potential…

The present article investigates spatial- and social-cognitive processes in toddlers' mapping of concepts to real-world events. In 2 studies we explore how event segmentation might lay the groundwork for extracting actions from the event stream and conceptually mapping novel verbs to these actions. In Study 1, toddlers demonstrated the ability to…

Infant and early childhood mental health practices can be supported by policies and professional standards of care that foster the healthy development of young children. Policies that support infants and toddlers include those that strengthen their families to provide a family environment that promotes mental wellness. Policy issues for infants,…

Children learning the inflections of their native language show the ability to generalize beyond the perceptual particulars of the examples they are exposed to. The phenomenon of "rule learning"--quick learning of abstract regularities from exposure to a limited set of stimuli--has become an important model system for understanding generalization…

From birth, infants detect associations between the locations of static visual objects and sounds they emit, but there is limited evidence regarding their sensitivity to the dynamic equivalent when a sound-emitting object moves. In 4 experiments involving thirty-six 2-month-olds, forty-eight 5-month-olds, and forty-eight 8-month-olds, we…

Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the…

Eye gaze is an important communicative signal, both as mutual eye contact and as referential gaze to objects. To examine whether attention to speech versus nonspeech stimuli in 4- to 5-month-olds (n = 15) varies as a function of eye gaze, event-related brain potentials were used. Faces with mutual or averted gaze were presented in combination with…

The "other-race" effect describes the phenomenon in which faces are difficult to distinguish from one another if they belong to an ethnic or racial group to which the observer has had little exposure. Adult observers typically display multiple forms of recognition error for other-race faces, and infants exhibit behavioral evidence of a developing…

All theories of language development suggest that learning is constrained. However, theories differ on whether these constraints arise from language-specific processes or have domain-general origins such as the characteristics of human perception and information processing. The current experiments explored constraints on statistical learning of…

Visual working memory (VWM) capacity has been studied extensively in adults, and methodological advances have enabled researchers to probe capacity limits in infancy using a preferential looking paradigm. Evidence suggests that capacity increases rapidly between 6 and 10 months of age. To understand how the VWM system develops, we must understand…
