Aims: Although IDS is typically described as slower than adult-directed speech (ADS), potential impacts of slower speech on language development have not been examined. We explored whether IDS speech rates in 42 mother-infant dyads at four time periods predicted children's language outcomes at two years. Method: We correlated IDS speech rate with…

The debate over the science of reading has focused primarily on decoding (i.e., connecting letters and sounds to read words) and whether to use phonics to teach it. However, research on reading has included much more than decoding. Language comprehension, which allows readers to derive meaning from text, is an equally critical component of…

We examined the size, content, and use of evaluative lexis by 26 English monolingual and 20 Spanish-English bilingual 30-month-old children in interaction with their mothers. We extracted the evaluative words, defined as words referring to cognition, volition, or emotion. Controlling for overall vocabulary skills as measured by the MacArthur-Bates…

Background: This study examined predictive relationships between two indices of language--receptive vocabulary and morphological comprehension--and inhibition in children with specific language impairment (SLI) and typically developing (TD) children. Methods: Participants included 30 children with SLI and 41 TD age-matched peers (8-12 years). At…

The purpose of this study was to examine the factor structure of vocabulary. We believe that not only is vocabulary multidimensional, but depth of vocabulary knowledge should also be assessed with multiple measures since it too, is composed of multiple aspects. Furthermore, to explore the predictive validity of the different aspects of vocabulary…

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…

The purpose of this study was to examine the relationship between reading interest strength and vocabulary acquisition in English as a Foreign Language (EFL) learners through a systematic review and meta-analysis of eleven relevant studies conducted over the last decade, from 2010 to 2020. This study attended by the guidelines of PRISMA. Several…

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…

Sleep right after studying new material is more conducive to memory than a period of wakefulness. Another way to counteract forgetting is to practice retrieval: taking a test strengthens memory more effectively than restudying the material. The current work aims at investigating the interaction between sleep and testing by asking if testing adds…

Purpose: Narrative skill represents a higher-level linguistic skill that shows incremental development in the preschool years. During these years, there are considerable individual differences in this skill, with some children being highly skilled narrators (i.e., precocious) relative to peers of their age. In this study, we explored the…

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…

Purpose: This mixed-methods study aimed to examine the conversation techniques used by parents of young children with hearing loss (HL) during dinnertime at home. Parents' usage rates of open- and closed-ended language elicitation, reformulation, imitation, directives, and explicit vocabulary instruction were examined in relation to children's…

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…

Purpose: The purpose of this study was to examine whether oral bilingualism could be an advantage for children with hearing loss when learning new words. Method: Twenty monolingual and 13 bilingual children with hearing loss were compared with each other and with 20 monolingual and 20 bilingual children with normal hearing on receptive vocabulary…
