English as a foreign language students in Japan learned target words in word pairs receptively and productively. Five aspects of vocabulary knowledge--orthography, association, syntax, grammatical functions, and meaning and form--were each measured by receptive and productive tests. The study uses an innovative methodology in that each target word…

Noun-class prefixes are obligatory in most Bantu languages. However, the Sotho languages (Sesotho, Setswana, Sepedi) permit a subset of prefixes to be realized as null at the intersection of "unmarked" phonological, syntactic, and discourse conditions. This raises the question of how and when the licensing of null prefixes is learned. Using…

In this article, we examine current practices in the measurement of syntactic complexity to illustrate the need for more organic and sustainable practices in the measurement of complexity, accuracy, and fluency (CAF) in second language production. Through in-depth review of examples drawn from research on instructed second language acquisition, we…

Six tests of the spontaneous speech of twenty-one English-speaking children (1 ; 10 to 2 ; 8; MLUs 1[middle dot]53 to 4[middle dot]38) demonstrate the presence of the syntactic category determiner from the start of combinatorial speech, supporting nativist accounts. Children use multiple determiners before a noun to the same extent as their…

Researchers have long been puzzled by children's variable omission of grammatical morphemes, often attributing this to a lack of semantic or syntactic competence. Recent studies suggest that some of this variability may be due to phonological constraints. This paper explored this issue further by conducting a longitudinal study of five…

Passives has been the focus of much research in language acquisition since the 1970s. It has been clear from this research that young children seldom produce passives spontaneously, particularly "long" or "full" passives with a by-phrase; and they usually perform poorly on experimental tests of the comprehension of passives, especially passives of…

While agreeing with Lardiere that the "parameter-resetting" approach to understanding second language acquisition (SLA) needs rethinking, it is suggested that a more construction-based perspective runs the risk of losing deductive and explanatory power. An alternative is to investigate the constraints on feature assembly/re-assembly in second…

Purpose: This study examined syntactic development in a large cohort of adolescents. At kindergarten, each participant had been identified as having specific language impairment (SLI), nonspecific language impairment (NLI), or typical language development (TLD). Method: The participants (n = 444) had a mean age of 13;11 (years;months; range =…

This study examined the existence of an object omission stage and the interaction between object omissions and substitution errors in the early stages of the development of Spanish syntax. One hundred and three Spanish-speaking children from Colombia completed an elicitation task evaluating the production of direct object pronouns. Results…

The present longitudinal study examines the role of caregiver speech in language development, especially syntactic development, using 47 parent-child pairs of diverse SES background from 14 to 46 months. We assess the diversity (variety) of words and syntactic structures produced by caregivers and children. We use lagged correlations to examine…

This study investigates the issue of crosslinguistic influence in the domain of subject realization in Turkish in simultaneous acquisition of Turkish and English. The use of subjects in a null subject language like Turkish is a phenomenon linked to the pragmatics-syntax interface of the grammar and, thus, is a domain where crosslinguistic…

This study examines the effects of learning context and age on second language development by comparing the language gains, measured in terms of oral and written fluency, lexical and syntactic complexity, and accuracy, experienced by four groups of learners of English: children in a study abroad setting, children in their at-home school, adults in…

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

Studies about bilingualism and second language acquisition (SLA) have a long tradition within linguistic and psycholinguistic research. The contributions from psycholinguistic research are crucial to the improvement of neurolinguistic models. This importance stems from the fact that psycholinguistic research is posing more specific questions than…

This study provides an account for a long-term selective loss of L1 (Russian) morpho-syntactic and content components in early immigrants to the U.S. The analysis of naturally occurring data is carried out from the perspective of two theoretical approaches--three models developed within language contact (Myers-Scotton 2002, 2005) and the…
