We sought to evaluate the efficacy of successive matching training for establishing generalized reflexive matching across 4 children with autism. In Experiment 1, differential reinforcement with delay fading was efficacious in establishing "yes" and "no" matching and nonmatching responses in 2 participants when 2 identical or…

Mandarin requires neither determiners nor morphological inflections, which casts doubt on Mandarin-speaking children's ability to use function words as a syntactic bootstrapping tool to identify the form class of a new word. This study examined 3- and 5-year-old Mandarin learners' ability to use function words to interpret new words as either…

This study explored the initial stages of adult second language (L2) learning with a special focus on the acquisition of the target language sound system. The aim was to analyze the longitudinal development of Spanish stop voicing contrasts in an immersion learning context. Native English-speaking late learners of Spanish provided production data…

Between 6 and 9 years of age, children's free associations shift from syntagmatic to paradigmatic relationships. "Syntagmatic relations" are words that are syntactically adjacent, thematically related ("summer-vacation"), or both; "paradigmatic relations" are words from the same grammatical class, taxonomic category…

Purpose: Parental language input (PLI) has reliably been found to influence child language development for children at risk of language delay, but previous work has generally restricted observations to the preschool years. The current study examined whether PLI during the early years explains variability in the spoken language abilities of…

Language sample analysis (LSA) has been called the "gold standard" for clinical language assessment with children learning more than one language. The research literature discussing this clinical tool with bilingual children has grown substantially in recent years. This article reviews and synthesizes the literature on LSA in order to…

Purpose: The study explored longitudinally the course of vocabulary and general language development in a group of infants with Down syndrome (DS) compared to a group of typically developing (TD) infants matched on nonverbal mental ability (NVMA). Method: We compared the vocabulary and general language trajectories of the two groups in two ways:…

In this series of experiments, we tested the limits of young infants' word learning and generalization abilities in light of recent findings reporting sophisticated word learning abilities in the first year of life. Ten-month-old infants were trained with two word-object pairs and tested with either the same or different members of the…

How to correct learner errors has long been of interest to both language teachers and second language acquisition (SLA) researchers. One way of doing so is through interactional feedback, which refers to feedback provided on learners' erroneous utterances during conversational interaction. Various theoretical claims have been made regarding the…

Purpose: As is the case with children who rely on spoken language, speech-language pathologists must support and track the expressive language development of children with complex communication needs who use graphic symbols to communicate. This research note presents a framework of the progression of expressive English sentence development using…

A surprising comprehension-production asymmetry in subject-verb (SV) agreement acquisition has been suggested in the literature, and recent research indicates that task-specific as well as language-specific features may contribute to this apparent asymmetry across languages. The present study investigates when during development children acquiring…

Previous research has shown that the quality of mother-child interactions between pre-term children and their mothers tends to be poorer than that of full-term children and their mothers (Forcada-Guex, Pierrehumbert, Borghini, Moessinger & Muller-Nix, 2006). Mothers of pre-term children are less responsive and more intrusive in interactions…

Music plays an important role in students' language development. Because the process of acquiring and developing language skills of the individual and learning to make music work have many similarities. In this quasi-experimental study, teaching the word in L1 with music with the normal intelligence and development level of 2nd-grade students on…

This paper aims to discuss old and contemporary perspectives in understanding language acquisition taking into account the neural theory of language. Discussing a recent theory by Kuhl (2010), neural substrates of first language learning will be put forward (Berwick et al., 2013). Neural substrates of phonetic learning, word learning, sentence…

Children with autism spectrum disorder often have significant language delays. But do they learn language differently than neurotypical toddlers? We compared the lexical skills of 64 preverbal and minimally verbal children with autism spectrum disorder to 461 vocabulary-size-matched typically developing toddlers. We also examined social features…
