Traditional educational giants and natural language processing companies have launched several artificial intelligence (AI)-enabled digital learning applications to facilitate language learning. One typical application of AI in digital language education is the automatic scoring application that provides feedback on pronunciation repeat outcomes.…

In this article, I examine how repairs in adult-child conversations guide children's acquisition of language. Children make unprompted self-repairs to their utterances. They also respond to prompts for repair, whether open ("Hm?," "What?") or restricted ("You hid what?"), and to restricted offers (Child: "I…

Purpose: This study examined vocabulary profiles in young cochlear implant (CI) recipients and in children with normal hearing (NH) matched on receptive vocabulary size to improve our understanding of young CI recipients' acquisition of word categories (e.g., common nouns or closed-class words). Method: We compared receptive and expressive…

The mechanisms underlying socioeconomic disparities in children's reading skills are not well understood. This study examined associations among socioeconomic background, home linguistic input, brain structure, and reading skills in 5-to-9-year-old children (N = 94). Naturalistic home audio recordings and high-resolution, T1-weighted MRI scans…

The aim of this study was to explore the relationship between paternal attitudes, father-child activities, socioeconomic and sociodemographic factors, and the early child productive vocabulary. We also wanted to study if paternal factors affected boys' and girls' language acquisition differently. Our data consisted of 722 fathers and their…

There are previous studies in the literature conducted on the effect of play-based math activities on the mathematical skills, language, and cognitive development of preschool children. However, the number of studies conducted to determine the effect of play-based math activities on different areas of development in preschool children was too few.…

Maternal input influences language development in children with Down syndrome (DS) and typical development (TD). Telegraphic input, or simplified input violating English grammatical rules, is controversial in speech-language pathology, yet no research to date has investigated whether mothers of children with DS use telegraphic input. This study…

Mental state terms are believed to be closely related to the development of Theory of Mind (ToM). This study focuses on mental state verbs (MSVs) and investigates how they are used by Japanese-speaking mother-child dyads compared to their English-speaking counterparts. Analyses of their spontaneous speech from the CHILDES archives show that…

When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of…

This review, which can be seen as a scoping review, highlights 92 empirical studies about the learning and instruction of reading Chinese as an additional language (CAL) published in English between 1976 and 2018. It first identifies and evaluates the trends of CAL reading research over the past four decades, including the developmental trajectory…

Fourteen-month-old infants are unable to link minimal pair nonsense words with novel objects (Stager & Werker, 1997). Might an adult's productions in a word learning context support minimal pair word-object association in these infants? We recorded a mother interacting with her 24-month-old son, and with her 5-month-old son, producing nonsense…

Purpose: The purpose of this study was to examine narrative language samples of Spanish-speaking preschoolers to analyze changes in microstructural and macrostructural skills in their first language (L1) from fall to spring, relationships between narrative and vocabulary skills in L1, and the extent to which fall skills predict spring performance.…

Purpose: Narrative skill, a child's ability to create a temporally sequenced account of an experience or event, is considered an important domain of children's language development. Narrative skill is strongly predictive of later language and literacy and is emphasized in curricula and educational standards. However, the need to transcribe a…

This dissertation is composed of two manuscripts that study the early development of infants at an elevated likelihood of an autism spectrum disorder diagnosis (EL-ASD). In the first manuscript, the language profiles (i.e., receptive dominant, expressive dominant, balanced) and the predictors of the language profiles are examined in infants at…
