Purpose: Within General American English (GAE), the grammar weaknesses of children with developmental language disorder (DLD) have been documented with many tasks, including grammaticality judgments. Recently, Vaughn et al. replicated this finding with a judgment task targeting tense and agreement (T/A) structures for children who spoke African…

Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

This study investigated cross-linguistic priming in six-year-old, balanced Spanish-English bilinguals (n = 60). We examined bilinguals' production of transitive forms in English (active, passive) after exposure to Spanish transitives (Study 1; M age = 6.2 years; SD = 0.3) and their production of transitive forms in Spanish (active, passive) after…

Purpose: The purpose of this study was (a) to examine the underlying components or factor structure of the Bilingual English-Spanish Assessment (BESA; Peña, Gutiérrez-Clellen, Iglesias, Goldstein, & Bedore, 2014) sentence repetition task and (b) to examine the relationship between Spanish-English speaking children's sentence repetition and…

We directly compare children learning argument expressing and argument dropping languages on the use of verb meaning and syntactic cues, by examining enactments of transitive and intransitive verbs given in transitive and intransitive syntactic frames. Our results show similarities in the children's knowledge: (1) Children were somewhat less…

A long history of research has considered the role of iconicity in language and the existence and role of nonarbitrary properties in language and the use of language. Previous studies with Japanese-speaking children, whose language defines a large grammatical class of words with clear sound symbolism, suggest that iconicity properties in Japanese…

Purpose: The question of how and when English-speaking children acquire auxiliaries is the subject of extensive debate. Some researchers posit the existence of innately given Universal Grammar principles to guide acquisition, although some aspects of the auxiliary system must be learned from the input. Others suggest that auxiliaries can be…

Data from one English-Italian bilingual child (1;10-3;1) are presented in this study which challenge the hypothesis that the consistent realization of overt subjects in English is caused by the emergence of finite verbal morphology in the child's grammar. The argument is made for the emergence of subjects as an independent grammatical property of…

The purpose of this research was to show how the syntactic and semantic components of the tense-aspect system interact during the acquisition process. Our methodology involved: (1) identifying predicates, (2) finding the initial occurrence of their tense-aspect morphology, and (3) observing the emergence of contrasts. Six children learning Polish…

Complex complements are clausal objects containing tensed verbs (e.g., that she cried) or infinitives (e.g., to cry), following main verbs of communication or mental activities (e.g., say, want). This research examined whether English- and Cantonese-speaking 4-year-olds' complement understanding uniquely predicts their representation of other…
