Background: Speech and language are interconnected systems, and language disorder often co-occurs with childhood apraxia of speech (CAS) and non-CAS speech sound disorders (SSDs). Potential trade-off effects between speech and language in connected speech in children without overt language disorder have been less explored. Method: Story retell…

Purpose: We examined the neurocognitive bases of lexical morphology in children of varied reading abilities to understand the role of meaning-based skills in learning to read with dyslexia. Method: Children completed auditory morphological and phonological awareness tasks during functional near-infrared spectroscopy neuroimaging. We first examined…

Human languages, signed and spoken, can be characterized by the structural patterns they use to associate communicative "forms" with "meanings." One such pattern is paradigmatic morphology, where complex words are built from the systematic use "and re-use" of sub-lexical units. Here, we provide evidence of emergent…

A defining feature of language lies in its capacity to represent meaning across oral and written forms. Morphemes, the smallest units of meaning in a language, are the fundamental building blocks that encode meaning, and morphological skills enable their effective use in oral and written language. Increasing evidence indicates that morphological…

Purpose: Morphological regularities are an important feature of the English writing system, and exposure to written morphology may be key in the development of skilled word recognition. Our aim was to investigate children's experiences of written morphology by analyzing a large-scale corpus of children's reading materials spanning a target age…

Purpose: This study investigated the production of tense and subject-verb agreement in Palestinian Arabic-speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method: Participants were 14 children with DLD aged 4;0-7;10 and…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…

Children's remarkable ability to generalize beyond the input and the resulting overregularizations/ irregularizations provide a platform for a discussion of whether morphology learning uses analogy-based, rule-based, or statistical learning procedures. The present study, testing 115 children (aged 3 to 10) on an elicited production task,…

Purpose: In this reply, we respond to comments on our article "Tracking the Growth of Tense and Agreement in Children With Specific Language Impairment: Differences Between Measures of Accuracy, Diversity, and Productivity." Conclusion: The finite verb morphology composite can be disproportionately affected by frequently occurring…

This systematic review and meta-analysis investigated the efficacy of spelling interventions for the remediation of dyslexia and spelling deficits. Theoretically important moderators, such as the treatment approach as well as orthographic and sample characteristics, were also considered. Thirty-four controlled trials that evaluated spelling…

The goal of the paper was to investigate whether morphological units -- stems and suffixes -- influence orthographic processing by modulating visual attention demands to the task. Orthographic processing was measured with a visual one-back task requiring letters to be detected within pseudowords not including stems/suffixes, or containing real…

Learning to mark for tense in a second language is notoriously difficult for speakers of a tenseless language like Chinese. In this study we test two reasons for these difficulties in Chinese-English sequential bilingual children: (1) morphophonological transfer (i.e., avoidance of complex codas), and (2) interpretation of -"ed" as an…

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

Morphemes, the smallest meaning-bearing units of language, recur in many words. Therefore, morphological knowledge can facilitate the comprehension of novel words. This study tested the effectiveness of a morphological training program on children's learning and retention of exposed words and morphologically related unexposed words compared with…

The current study examined the production of Hebrew verbal passives across adolescence as mediated by linguistic register and verb morphology. Participants aged eight to sixteen years and a group of adults were asked to change written active-voice sentences into corresponding passive-voice forms, divided by verb register (neutral and high),…
