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…

This dissertation concerns the acquisition of the interaction between lexicosemantic properties of verbs and syntax, focusing on symmetrical and asymmetrical verbs in different syntactic structures. Based on linguistic evidence, it is shown that two conceptual categories, Mutuality and Number, interact to give rise to four event-types: Single…

To examine the role of morphology in verbal working memory. Forty nine children, all native speakers of Arabic from the same region and of the same dialect, performed a "Listening Word Span Task", whereby they had to recall Arabic uninflected words (i.e., base words), inflected words with regular (possessive) morphology, or inflected words with…

Very high-level, functional ability in foreign languages is increasingly important in many walks of life. It is also very rare, and likely requires an early start and/or a special aptitude. This study investigated the extent to which aptitude for explicit learning, defined as "analytic ability" and aptitude for implicit learning, defined…

While normal child language acquisition results in complete productive and comprehension abilities at a relatively young age, adult language acquisition is more belabored and often results in linguistic abilities that differ from those of native speakers in terms of both productive and comprehension abilities. A major line of research in language…

We report the results of two studies that investigate the factors contributing to non-native-like ability in child and adult heritage speakers by focusing on oral production of Differential Object Marking (DOM), the overt morphological marking of animate direct objects in Spanish. In study 1, 39 school-age bilingual children (ages 6-17) from the…

The incidence of nativelikeness in adult second language acquisition is a controversial issue in SLA research. Although some researchers claim that any learner, regardless of age of acquisition, can attain nativelike levels of second language (L2) proficiency, others hold that attainment of nativelike proficiency is, in principle, impossible. The…

This paper reports the findings of a psycholinguistic study of the development of phonological awareness (PA) in Chinese children acquiring their first language and learning a foreign language at the same time. The language situation of these children in relation to PA is of particular interest because Chinese and English have not only different…

Clahsen and Felser (CF) analyze the performance of monolingual children and adult second language (L2) learners in off-line and on-line tasks and compare their performance with that of adult monolinguals. They conclude that child first language (L1) processing is basically the same as adult L1 processing (the contiguity assumption), with…
