Purpose: The results of automatic machine scoring of the Index of Productive Syntax from the Computerized Language ANalysis (CLAN) tools of the Child Language Data Exchange System of TalkBank (MacWhinney, 2000) were compared to manual scoring to determine the accuracy of the machine-scored method. Method: Twenty transcripts of 10 children from…

This study addresses the question of whether gender agreement is impaired in SLI German. Article production and gender marking on articles were examined in three groups of German-speaking children: 10 children with Specific Language Impairment (SLI), 10 age-matched typically developing (TD) children, and 10 TD children who were on average two…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

Purpose: The Index of Productive Syntax (IPSyn; Scarborough, 1990) is widely used to measure syntax production in young children. The goal of this article is to promote greater clarity and consistency in machine and hand scoring by presenting a revised version of the IPSyn (IPSyn-R) and comparing it with the original IPSyn (IPSyn-O). Method:…

Previous research on young children's knowledge of prosodic focus marking has revealed an apparent paradox, with comprehension appearing to lag behind production. Comprehension of prosodic focus is difficult to study experimentally due to its subtle and ambiguous contribution to pragmatic meaning. We designed a novel comprehension task, which…

Preschoolers' earliest productions of sentential complement sentences have matrix clauses that are limited in form. Diessel proposed that matrix clauses in these early productions are propositionally empty fixed phrases that lack semantic and syntactic integration with the clausal complement. By 4 years of age, however, preschoolers produce…

We examine the second language (L2) acquisition of variable Spanish word order by first language (L1) speakers of English via the acquisition of unaccusative and transitive predicates in various focus-related contexts. We employ two bimodal linguistic tasks: (1) acceptability judgment task (B-AJT) and (2) appropriateness preference task (B-APT).…

Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

Previous research has shown that children demonstrate similar sentence processing reflexes to those observed in adults, but they have difficulties revising an erroneous initial interpretation when they process garden-path sentences, passives, and "wh"-questions. We used the visual-world paradigm to examine children's use of syntactic and…

Background: Late language emergence is a risk indicator for developmental language disorder. Parent-implemented early language intervention programmes (parent programmes) have been shown to have positive effects on children's receptive and expressive language skills. However, long-term effectiveness has rarely been studied. Additionally, little is…

The objective of this work was to analyze morphosyntactic development in a wide sample of children with Down syndrome (DS) ("n" = 92) and children with typical development (TD) ("n" = 92) with a mental age (MA) of 20 to 29 months. Children were individually matched for gender and MA (Analysis 1) and for vocabulary size…

We compare the predictions of two different accounts of first language acquisition by investigating the relative contributions of abstract syntax and input frequency to the elicited production of main and embedded questions by 36 monolingual English-speaking toddlers aged 3;00 to 5;11. In particular, we investigate whether children's accuracy…

The present study compared the performance of twenty-seven French-speaking internationally adopted (IA) children from China to that of twenty-seven monolingual non-adopted French-speaking children (CTL) matched for age, gender, and socioeconomic status on a Clitic Elicitation task. The IA children omitted significantly more accusative object…

Previously published corpora of two-word utterances by three chimpanzees and three human children were compared to determine whether, as has been claimed, apes possess the same basic syntactic and semantic capacities as 2-year old children. Some similarities were observed in the type of semantic relations expressed by the two groups; however,…

Spontaneous language samples are a useful tool in studying the nature of morphosyntactic production in both clinical and academic settings. However, little work has been done on typical frequency of occurrence of morpheme production and even less on the degree of temporal reliability of morpheme frequency between samples. This study compares two…
