Studies of the acquisition of verbs tend to focus on one-verb predicates of the prevalent English type. But in hundreds of languages around the world, multi-verb predicates like serial verb constructions are widely used. It could be reasoned that children should begin producing simple, single-verb predicates before they are able to produce…

Causatives have received considerable attention in first language acquisition. Of Mayan languages, acquisition of the causative has only been investigated for K'iche' and Tzotzil, based on longitudinal and spontaneous data. K'iche'-speaking children do not acquire morphological causatives until the age of 3 years, while children acquiring Tzotzil…

Background and aims: Play is used by practitioners from across disciplinary backgrounds as a natural and enjoyable context for providing intervention and support in early childhood. In the case of autism interventions, many therapies are based on the association between social play and the development of social skills, language development, and…

"How do you feel when you speak Zapotec?" According to some children who are learning Zapotec, an Indigenous language spoken in Teotitlan del Valle, Mexico, speaking Zapotec invokes feelings of pride. But not all learners feel this way, and children's feelings often vary depending on the specifics of a particular interaction. In this…

We present a description and an analysis of three related language games in Africa's Gulf of Guinea: Fa d'Ambô's Fa do Vesu, Lung'Ie's Faa di Vesu, and São Tomé and Príncipe Portuguese's P-language. We show how these language games can be used to investigate the linguistic features of their main languages and as learning resources for second…

Pitch discrimination, or the ability to differentiate stimuli using auditory frequency, may be an important correlate of language acquisition. Research consistently finds that children with autism spectrum disorder (ASD) have differences in auditory discrimination abilities. However, studies linking these abilities to delays or impairments in…

Previous research has documented that children count spatiotemporally-distinct partial objects as if they were whole objects. This behavior extends beyond counting to inclusion of partial objects in assessment and comparisons of quantities. Multiple accounts of this performance have been proposed: children and adults differ qualitatively in their…

The role of children's verbal repetition of parents' utterances on vocabulary growth has been well documented (Masur, 1999). Nevertheless, few studies have analyzed adults' and children's spontaneous verbal repetition around the second birthday distinguishing between the types of repetition. We analyzed longitudinally Spanish-speaking parent-child…

Background: The perceptual similarity between two objects, specifically similarity in the shape of the referents, is a crucial element for relating words in earlier stages of development. The role of this perceptual similarity has not been systematically explored in children with Down syndrome (DS). Method: The aim was to explore the role of…

Turn and Talk is widely used in early-grade classrooms, but very little rigorous research or evidence-based guidance has been offered to teachers. In this exploratory paper, we take the first step toward establishing a teacher-friendly discussion on this common technique. After briefly describing the Turn and Talk technique, we first ask: What…

Although use of machine translation (MT) technologies by learners may seem like a relatively new issue in foreign language (FL) education, researchers have been investigating connections between MT tools and FL teaching and learning for more than three decades, years before learners had access to free online services such as Google Translate. This…

Might dialogic reading require previous or concurrent embodied activities to be effective? Twenty-nine preschool children, ages 3-5 years, were randomly assigned to the control condition (children listened to a story eight times), the dialogic-then-embodied condition (children engaged in dialogic reading for four readings and then embodied action…

Learning in any domain depends on how the data for learning are represented. In the domain of language acquisition, children's representations of the speech they hear determine what generalizations they can draw about their target grammar. But these input representations change over development as a function of children's developing linguistic…

The purpose of this study was to consider how living in an area that qualifies for a rural health grant interacts with a child's hearing status to affect early language and literacy development. Four-year-old children with hearing aids (n = 45), cochlear implants (n = 47), and with typical hearing (n = 66) completed measures of spoken language…

This paper invites us to reconsider our usual understanding of infancy, no longer as something that passes but as "infantia." The Latin word "infantia," which is not easy to translate, means a lack of speech, a lack of eloquence, and also infancy, babyhood, and dumbness. Drawing on Barbara Cassin's works on the untranslatables,…
