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…

A critical question in the study of language development is to understand lexical and syntactic acquisition, which play different roles in speech to the extent it would be natural to surmise they are acquired differently. As measured through the comprehension and production of closed-class words, syntactic ability emerges at roughly the 400-word…

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…

Infant-directed speech (IDS) is a specific register that adults use to address infants, and it is characterised by prosodic exaggeration and lexical and syntactic simplification. Several authors have underlined that this simplified speech becomes more complex according to the infant's age. However, there is a lack of studies on lexical and…

Previous studies suggest that age of acquisition affects the outcomes of learning, especially at the morphosyntactic level. Unknown is how syntactic development is affected by increased cognitive maturity and delayed language onset. The current paper studied the early syntactic development of adolescent first language learners by examining word…

Studies examining productive syntax have used varying elicitation methods and have tended to focus on either young children or adolescents/adults, so we lack an account of syntactic development throughout middle childhood. We describe here the results of an analysis of clause complexity in narratives produced by 354 speakers aged from four years…

This study investigated the development of evaluation in narratives from middle to late childhood, within the context of differentiating between spoken and written modalities. Two parallel forms of a picture story were used to elicit spoken and written narratives from fourth- and sixth-graders. It was expected that, in addition to an increase of…

Children categorize native-accented speakers as local and non-native-accented speakers as foreign, suggesting they use accent (i.e., phonological proficiency) to determine social group membership. However, it is unclear if accent is the strongest--AND ONLY--group marker children use to determine social group membership, or whether other aspects of…

We report a syntactic priming experiment that examined whether children's acquisition of the passive is a staged process, with acquisition of constituent structure preceding acquisition of thematic role mappings. Six-year-olds and nine-year-olds described transitive actions after hearing active and passive prime descriptions involving the same or…

The present study exposed five-year-olds (M=5 ; 2), seven-year-olds (M=7 ; 6) and adults (M=22 ; 4) to instances of a novel phrasal construction, then used a forced choice comprehension task to evaluate their learning of the construction. The abstractness of participants' acquired representations of the novel construction was evaluated by varying…

Investigated the development of syntactic awareness in Cantonese-speaking children. Fifty-six subjects from four age groups were asked to judge the grammaticality of 40 sentences and to correct the grammatically-deviant sentences. There was a significant age effect on subject's performance in both judgment and revision tasks. (Author/VWL)

Examination of the effect of two linguistic factors on kindergarten through fourth-grade students' understanding of idioms indicated that the younger subjects better understood syntactically frozen idioms than those presented in various syntactic forms, while older subjects comprehended both kinds. (Author/CB)

The relationship between knowledge and reasoning was explored through 12 males' and 12 females' (aged 12, 15, and adult) solutions to written syllogisms containing four conjunctions, and evaluations of single sentences for their pragmatic content. The relationship between comprehension of pragmatic uncertainty and detection of uncertain…

Examined the distribution of two Hebrew nominal structures in spoken and written texts of two genres produced by 90 native-speaking participants. Written texts were found to be denser than spoken texts lexically and syntactically as measured by a number of novel N-N compounds and denominal adjectives per clause; in older age groups this difference…

Comprehension of relative clauses was assessed in 10 Hebrew-speaking school-age children with syntactic SLI and in two groups of younger children with normal language development. Comprehension of subject- and object-relatives was assessed using a binary sentence-picture matching task. The findings were that while Hebrew-speaking children with…
