Background: Understanding memory retention in children with developmental language disorder (DLD) compared with their typically developing (TD) peers enhances our knowledge of memory processes. Aims: To examine long-term memory consolidation of a declarative object-location task and a procedural symbol-writing task, along with grammatical and…

This study investigates the role of recursive language and working memory (WM) in second-order false belief skills in Danish-speaking children with autism spectrum disorder (ASD; n = 62; 8 females) and typical development (n = 41; 15 females), ages 6-16. Second-order false belief skills correlated with receptive grammar, vocabulary, and age;…

The deficit in verbal working memory (vWM) skills has been frequently reported in children with developmental language disorder (DLD) and may contribute to their problems in language. This study aimed to compare the phonological short-term memory (pSTM) and linguistic skills between Persian-speaking children with DLD and typical language…

Background and aims: Previous studies suggest that syntactic development in children with intellectual disabilities (ID) is positively correlated with verbal short-term memory (VSTM). This study investigated the characteristics of syntactic development and their relationships of VSTM in children with ID based on type. Methods: The participants…

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…

We tested theories of links between musical expertise and language ability in a sample of 6- to 9-year-old children. Language ability was measured with tests of speech perception and grammar. Musical expertise was measured with a test of musical ability that had 3 subtests (melody discrimination, rhythm discrimination, and long-term memory for…

The procedural deficit hypothesis claims that impaired procedural learning is a causal risk factor for developmental dyslexia and developmental language disorder. We investigated the relationships between measures of basic cognitive processes (declarative learning, procedural learning and attention) and measures of attainment (reading, grammar and…

Purpose: The fine-tuning of linguistic prosody in later childhood is poorly understood, and its neurological processing is even less well studied. In particular, it is unknown if grammatical processing of prosody is left- or rightlateralized in childhood versus adulthood and how phonological working memory might modulate such lateralization.…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

We examined the concurrent relationship between narrative skills (the Renfrew Bus Story Test) and core language measures (vocabulary, grammar and verbal memory) at age 4 and the longitudinal relationship between core language and listening comprehension skills at age 7 in a sample of 215 children using latent variables and structural equation…

This study addresses the question as to what cognitive abilities influence performance on article choice and direct object scrambling in high-functioning Dutch-speaking children with Autism Spectrum Disorder (ASD). Schaeffer (2016/2018) shows that a group of 27 high-functioning Dutch-speaking children with ASD, aged 5-14, overgenerates the…

Purpose: This study examined whether children and adults with developmental language disorder (DLD) could use distributional information in an artificial language to learn about grammatical category membership similarly to their typically developing (TD) peers and whether developmental differences existed within and between DLD and TD groups.…

In natural language, evidence suggests that, while some rules are productive (regular), applying broadly to new words, others are restricted to a specific set of lexical items (irregular). Further, the literature suggests that children make a categorical distinction between regular and irregular rules, applying only regular rules productively…

This study adjudicates between two opposing accounts of morphological productivity, using English past-tense as its test case. The single-route model (e.g., Bybee & Moder, 1983) posits that both regular and irregular past-tense forms are generated by analogy across stored exemplars in associative memory. In contrast, the dual-route model…

Scholars debate whether musical and linguistic abilities are associated or independent. In the present study, we examined whether musical rhythm skills predict receptive grammar proficiency in childhood. In Experiment 1, 7- to 17-year-old children (N = 68) were tested on their grammar and rhythm abilities. In the grammar-comprehension task,…
