Upon hearing a novel label, listeners tend to assume that it refers to a novel, rather than a familiar object. While this disambiguation or mutual exclusivity (ME) effect has been robustly shown across development, it is unclear what it involves. Do listeners use their pragmatic and lexical knowledge to exclude the familiar object and thus select…

In successful communication, it is critical to have the ability to identify what a speaker is referring to from previously mentioned information. This ability requires the identification of the topic initially introduced by lexical forms and its continuity in discourse expressed by anaphora such as null and pronominal forms in the subsequent…

The acoustic properties of infant-directed speech (IDS) have been widely studied, but whether and how young learners' language development benefits from individual properties remains to be confirmed. This study investigated whether toddlers' word processing was affected by tone hyperarticulation in the IDS of a tone language. Nineteen- and…

Successful word recognition requires that listeners attend to differences that are phonemic in the language while also remaining flexible to the variation introduced by different voices and accents. Previous work has demonstrated that American-English-learning 19-month-olds are able to balance these demands: although one-off one-feature…

English-speaking children use plural morphology from around the age of 2, yet often omit the syllabic plural allomorph /-[schwa]z/ until age 5 (e.g., "bus(es)"). It is not clear if this protracted acquisition is due to articulatory difficulties, low input frequency, or fricative-final words (e.g., "bus," "nose") being…

We examined French-learning toddlers' sensitivity to Subject-Verb agreement with conjoined subjects. In French, a conjoined NP triggers plural agreement even when made up of individual singular NPs. Processing of this infrequent structure in the input (see Corpus Analyses) requires going beyond surface patterns of non-adjacent dependencies to…

We investigated toddlers' phonological representations of common vowel-initial words that can take on multiple surface forms in the input. In French, liaison consonants are inserted and are syllabified as onsets in subsequent vowel-initial words, for example, petit /t/ éléphant [little elephant]. We aimed to better understand the impact on…

Speech disorders are in almost all speech pathology accompanied by a symptom. They usually occur during speech development. Baby. First TV describes itself as a provider of shows 'designed to inspire a baby's learning'. However, if a child is presented to a continental strangling program that does not serve the mother tongue, it can have a lot of…

The article focuses on the omission of locative prepositions in child Russian. We report on two experiments: a production task and a comprehension task. Results from the elicited production task show that the majority of 2- and a minority of 3-year-olds (i) omit locative prepositions at nonnegligible rates, and (ii) do not conform to targetlike…

Assessing a child's language in the early years is critical to plan for an early intervention and maximize their learning potential. In a unique pan-Arabic approach to language development, we developed a new Arabic assessment tool, usable by parents and Early Years professionals to screen vocabulary in children between 8 months and 30 months…

Purpose: This study investigates how the variables of culture and hearing status might influence the amount of parent-child talk families engage in throughout an average day. Method: Seventeen Vietnamese and 8 Canadian families of children with hearing loss and 17 Vietnamese and 13 Canadian families with typically hearing children between the ages…

This mixed two-way experimental, cross-sectional study investigated fast-mapping (FM) of novel nouns and verbs in 63 Persian-speaking toddlers aged 30 months, including 31 late-talking (LT) and 32 typically developing (TD) matched with respect to age and maternal education. Toddlers were classified as LT if they had limited expressive vocabulary…

We report on an analysis of spontaneous gesture production in 2-year-old children who come from three countries (Italy, United Kingdom, Australia) and who speak two languages (Italian, English), in an attempt to tease apart the influence of language and culture when comparing children from different cultural and linguistic environments.…

The goal of the current study was to statistically evaluate the reliable scalability of a set of tasks designed to assess Theory of Mind (ToM) without language as a confounding variable. This tool might be useful to study ToM in populations where language is impaired or to study links between language and ToM. Low verbal versions of the ToM tasks…

The ELO-L (Évaluation du langage oral chez l'enfant libanais) is the first norm-referenced language-screening test in Lebanon. It is an adaptation of the ELO, a French language-screening test. The ELO-L was normed on 1,718 children aged three to eight years and divided into eight age groups with a minimum of 100 participants in each group. It is…
