Iconic words imitate their meanings. Previous work has demonstrated that iconic words are more common in infants' early speech, and in adults' child-directed speech (e.g., Perry et al., 2015; 2018). This is consistent with the proposal that iconicity provides a benefit to word learning. Here we explored iconicity in four diverse language…

Previous research on the L1 acquisition of motion event expression suggests that mapping multiple semantic components onto syntactic units is associated with greater difficulties in verb-framed than in satellite-framed languages, because the former require more complex structures (using subordination). This study investigated the impact of this…

Purpose: Children with developmental language disorder (DLD) have persistent language difficulties in complex syntax. To date, few studies have examined the effectiveness of syntactic training focusing on complex grammar, with no existing studies having been done in French. In English, the SHAPE CODING (SC) system, which combines shapes and colors…

Prediction-based accounts of language acquisition have the potential to explain several different effects in child language acquisition and adult language processing. However, evidence regarding the developmental predictions of such accounts is mixed. Here, we consider several predictions of these accounts in two large-scale developmental studies…

Purpose: Despite the considerable scientific interest in researching the reading skills of the deaf population, most of these studies focus on reading comprehension (RC) at the word or sentence level. Such reading activates different underlying language processes than text-level reading, which is more akin to real-life reading literacy. The…

During language acquisition, children are tasked with the challenge of determining which words can appear in which syntactic constructions. This has been long recognized as a learnability paradox. On one hand, there are generalizations that children must learn. On the other hand, language is known for its arbitrariness, so children also need to…

Among the existing sign language assessment tools, only a small number can be used in clinical settings. This contribution aims at presenting three comprehension assessment tests (two lexical and one syntactic) that offer a solid basis to build tools to assess language impairments in deaf signing adults. We provide the material and guidelines,…

Theories of language processing differ with respect to the role of abstract syntax and semantics vs surface-level lexical co-occurrence (n-gram) frequency. The contribution of each of these factors has been demonstrated in previous studies of children and adults, but none have investigated them jointly. This study evaluated the role of all three…

Background and aims: Although autism spectrum disorder (ASD) has not traditionally been associated with morphosyntactic impairments, some children with ASD manifest significant difficulties in this domain. Sentence Repetition (SRep) tasks are highly reliable tools for detecting morphosyntactic impairment in different languages and across various…

This study investigated the comprehension of prosodically and syntactically marked focus by 5- to 8-year-old Cantonese-speaking children with and without autism spectrum disorder (ASD). Children listened to question-answer dialogues while looking at pictures depicting the scenarios, and judged whether the answers were correct responses to the…

How do children infer the meaning of a novel verb? One prominent proposal is that children rely on syntactic information in the linguistic context, a phenomenon known as "syntactic bootstrapping". For example, given the sentence "The bunny is gorping the duck," a child could use knowledge of English syntactic roles to infer…

In addition to deficits in pragmatics, children with autism spectrum disorders (ASD) have weaknesses in complex syntax and working memory (WM). These two deficits may be closely related. Previous work investigated the effects of WM training in developmental language disorders and showed significant improvement in both WM and syntax. The current…

Based on the bilingual children's and adults' code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children's CS and compares them with bilingual adults'. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest…

Purpose: The current study examines bilingual children's development of Spanish and English morphosyntax structures over the period of 1 year. Identification of morphosyntax forms clustered by difficulty can elucidate their development and guide clinicians to select appropriate targets for intervention and monitoring. Specifically, we aim to…

This case study describes the use of a syntax intervention with two deaf children who did not acquire a complete first language (L1) from birth. It looks specifically at their ability to produce subject-verb-object (SVO) sentence structure in American Sign Language (ASL) after receiving intervention. This was an exploratory case study in which…
