This study investigated phonological whole-word measures in bilingual Arabic-English speakers to explore how the target approximations influence children's phonological development. To this end, fifteen bilingual Arabic-English speakers and nine monolingual Arabic-speaking children aged 36-48 months (mean = 42) participated in a parent-child…

Purpose: Autistic individuals often face challenges perceiving and expressing emotions, potentially stemming from differences in speech prosody. Here we explore how autism diagnoses between groups, and measures of social competence within groups may be related to, first, children's speech characteristics (both prosodic features and amount of…

Background: Children who stutter have the right to express their views and be heard. However, in research on stuttering, attention tends to focus mainly on parental and adult perspectives. By actively engaging with children's viewpoints, we can enhance our understanding of their distinct needs and capabilities. This, in turn, enables the…

Eye-tracking studies tested the understanding of two types of speech acts (questions and assertions) in 14-, 18-, and 30-month-olds (N = 280; 149 females; ethnicity data collection forbidden, testing in 2021-2024). Experiments involved objects either hidden or visible for a speaker. By 14 months, when the speaker asked questions, infants focused…

To investigate how a high risk for infant neurological impairment affects the quality of infant verbal interactions, and in particular properties of infant-directed speech, spontaneous interactions between 14 mothers and their 4.5-month-old infants at high risk for neurological disorders (7 female) were recorded and acoustically compared with…

Purpose: Talkers adapt their speech according to the demands of their listeners and the communicative context, enhancing the properties of the signal (pitch, intensity) and/or properties of the code (enhancement of phonemic contrasts). This study asked how mothers adapt their child-directed speech (CDS) in ways that might serve the immediate goals…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

Inspired by research in language play and linguistic ethnography, this article examines children's language play in early childhood education and care (ECEC) as a locally situated generic practice created through children's semiotic repertoires. The article is based on video-recorded linguistic ethnographic fieldwork in a Danish day care centre.…

Objectives: The study aimed to investigate the predictive potential of language environment and vocal development status measures obtained through integrated analysis of Language ENvironment Analysis (LENA) recordings during the prelinguistic stage for subsequent speech and language development in Korean-acquiring children. Specifically, this…

Sentences that have more than one possible meaning are said to be syntactically ambiguous (SA). Because the correct interpretation of these sentences can be unclear, resolving SA sentences can be cognitively demanding for children, particularly with regards to inhibitory control (IC). In this study we provide three lines of evidence supporting the…

The purpose of the current study was to revisit a controversial topic: whether frequencies of phonological consonant and vowel classes differ in speech directed to children and to adults. In addition, the current study investigated whether the frequency of phonological consonant and vowel classes changes with children's increasing chronological…

Purpose: Disfluencies can be classified as stuttering-like disfluencies (SLDs) or typical disfluencies (TDs). Dividing TDs further, stalls (fillers and repetitions) are thought to be prospective, occurring due to planning glitches, and revisions (word and phrase revisions, word fragments) are thought to be retrospective, occurring when a speaker…

Multiple approaches -- including observational and experimental -- are necessary to articulate powerful theories of learning. Our field's key questions, which rely on these varied methods, are still open. How do children perceive and produce language? What do they encounter in their linguistic input? What does the learner bring to the task of…

Forty-eight toddlers participated in a word-learning task to assess gesture input on mapping nonce words to unfamiliar objects. Receptive fast mapping and expressive naming for target object-word pairs were tested in three conditions -- with a point, with a shape gesture, and in a no-gesture, word-only condition. No statistically significant…

Like verbs, adjectives pose a challenge to the young word learner in that some -- like "red," "round," "rough," or "rectangular" -- map onto properties that are detectable through the senses, while others -- like "ready," "reasonable," or "required" -- express abstract…
