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…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

Purpose: Grammatical morphology is often a locus of difficulty for both children with language impairment (LI) and bilingual children. In contrast to previous research that mainly focused on verbal tense and agreement markings, the present study investigated whether plural and past participle formation can disentangle the effects of LI and…

We examine whether German children attach an adultlike relevance to the pragmatic category of polarity contrast (e.g., "In my picture the child IS eating the candies" following after "In my picture the child is not eating the candies") with linguistic expressions (i.e., the affirmative particles…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

Vocabulary plays a critical role in language and reading development for children, particularly those learning English as an additional language (EAL) (Stahl & Nagy, 2006). Previous research on vocabulary has mainly focused on measuring individual words without considering multi-word phrase knowledge, despite evidence that these items occur…

Purpose: In this study, the authors investigated whether errors with subject-verb agreement in monolingual Dutch children with specific language impairment (SLI) are influenced by verb phonology. In addition, the productive and receptive abilities of Dutch acquiring children with SLI regarding agreement inflection were compared. Method: An SLI…

Both children with specific language impairment (SLI) and children who acquire a second language (L2) make errors with verb inflection. This overlap between SLI and L2 raises the question if verb inflection can discriminate between L2 children with and without SLI. In this study we addressed this question for Dutch. The secondary goal of the study…

The data on language acquisition in children with specific language impairment (SLI) primarily come from studies in English reporting particular morphemes that differentiate them from their typically developing (TYP) peers, but markers of impairment vary cross-linguistically. There is some cross-linguistic evidence that SLI disrupts language…

In this study we investigate the linguistic performance of a school age French-Greek simultaneous bilingual boy with specific language impairment (SLI) on the production of subject-verb agreement, object clitic pronouns and wh-questions. In addition, we compare his performance on these linguistic structures with that of two French-Greek bilingual…

We investigated the role of number agreement on verb and of animacy in the comprehension of subject and object relative clauses in 51 monolingual Italian-speaking children, mean age 9:33, tested through a self-paced listening experiment with a final comprehension question. A "digit span test" and a "listening span test" were…

The present study investigates flexibility of verb use in the early stages of English multiword development, and its relationship with patterns attested in the input. The data is taken from a case study of a monolingual English-speaking boy aged 2; 5-2; 9 and his mother while engaged in daily activities in the home. Data were coded according to…

In the present study, the natural and simultaneous first language acquisition of a German-Italian bilingual boy and an Italian monolingual girl from 1;8 to 2;1 are analyzed and compared. The investigation focuses on the rate of acquisition and the size and composition of the productive lexicons. At the end of the observation period, the bilingual…

We investigated the processing of agreement marking and case marking in the comprehension of German relative clauses in 48 seven-year-old monolingual German-speaking children in a picture selection task. We examined the relation between the effectiveness of these different morphological cues and individual memory resources as measured by a…

The present study takes as a point of departure Becker's analysis of the copula "be" in English monolingual data and focuses on the distribution of copula "be" in the data from two English/Spanish bilingual children. Our data analysis shows that, as in Becker's study, the distribution of copula omission in the bilingual data is determined by the…
