Children achieve better long-term language outcomes than adults. However, it remains unclear whether children actually learn language "more quickly" than adults during real-time exposure to input--indicative of true superior language learning abilities--or whether this advantage stems from other factors. To examine this issue, we…

Background: Children with speech sound disorders (SSD) are at higher risk of communication breakdown, but the impact of having an SSD may vary from child to child. Determining the severity of SSD helps speech-language therapists (SLTs) to recognise the extent of the problem and to identify and prioritise children who require intervention. Aims:…

This qualitative ethnographic research explores baby talk (BT) and ontology of infancy in a small, rural Indo-Fijian community via semistructured interviews with mothers about their children's language learning, mothers' narratives about their photographs of their young children engaged in everyday language, and audio- and video-recordings of…

Using computational simulations, this work demonstrates that it is possible to learn a systematic relation between words' sound and their meanings. The sound-meaning relation was learned from a corpus of phonologically transcribed child-directed speech by using the linear discriminative learning (LDL) framework (Baayen, Chuang, Shafaei-Bajestan,…

Purpose: This study examines the accuracy of Interaction Detection in Early Childhood Settings (IDEAS), a program that automatically transcribes audio files and estimates linguistic units relevant to speech-language therapy, including part-of-speech units that represent features of language complexity, such as adjectives and coordinating…

Purpose: The aim of this study was to investigate the appropriateness of standardized assessments of expressive grammar and vocabulary in a sample of preschool-age dual language learners (DLLs) who use Jamaican Creole (JC) and English. Adult models from the same linguistic community as these children were used to inform culturally and…

Perturbations to the speech articulators induced by frequently using an interfering object during infancy (i.e., pacifier) might shape children's language experience and the building of conceptual representations. Seventy-one typically developing third graders performed a semantic categorization task with abstract, concrete and emotional words.…

Robust evidence exists for the shape bias, or children's tendency to extend novel names and categorize objects more readily on the basis of shape than on other object features. However, issues remain about the conditions that affect the shape bias and its importance as a linguistic device. In this research, we examined how type of instruction…

One strategy that children might use to sort words into grammatical categories such as noun and verb is distributional bootstrapping, in which local co-occurrence information is used to distinguish between categories. Words that can be used in more than one grammatical category could be problematic for this approach. Using naturalistic corpus…

The present study looks into the largely unexplored territory of the cognitive underpinnings of semantic approximations in child language. The analysis of a corpus of 233 semantic approximations produced by 101 monolingual French-speaking children from 1;8 to 4;2 years of age leads to a classification of a significant number of them as instances…

How do children resolve the problem of indeterminacy when learning a new word? By one account, children adopt a "taxonomic assumption" and expect the word to denote only members of a particular taxonomic category. According to one version of this constraint, young children should represent polysemous words that label multiple kinds--for…

Two-year-olds use the sentence structures verbs appear in--"subcategorization frames"--to guide verb learning. This is syntactic bootstrapping. This study probed the developmental origins of this ability. The structure-mapping account proposes that children begin with a bias toward one-to-one mapping between nouns in sentences and participant…

Purpose: This study evaluated the consistency in severity classifications for children with language impairment on tests of child language. Methods: The TELD-3 and the UTLD-4 were administered to 16 preschool children with specific language impairment (SLI) and 16 typical controls. The boundaries described in the test manuals were used to assign…

The aim of this study was to investigate the impact of Socio-Economic Status (SES) on Hebrew-speaking children's developing ability to pluralize nouns and mark adjectives in agreement with them. Participants were 180 gradeschool children from mid-high SES and 180 peers from low SES, in six consecutive grade levels. The task consisted of 32…

Semantic roles are a critical aspect of linguistic knowledge because they indicate the relations of the participants in an event to the main predicate. Experimental studies on children and adults show that both groups use associations between general semantic roles such as Agent and Theme, and grammatical positions such as Subject and Object, even…
