This study reports on the use of (c)overt subjects and subject–verb agreement in Hebrew in the spontaneous speech of a child, EK, acquiring Hebrew and English simultaneously from birth and of five slightly younger Hebrew monolingual controls. Analysis shows that EK's production of pragmatically inappropriate overt subjects is more than three times that of the controls, while she resembles the controls in terms of subject–verb agreement, a purely syntactic phenomenon. These results strongly suggest that influence from English is restricted to phenomena that involve the syntax/pragmatics interface, supporting Hulk and Müller's (2000) hypothesis that crosslinguistic influence in early bilingual acquisition is a predictable and systematic phenomenon.

In this special collection we bring together experimental studies on the semantic and cognitive correlates of the syntactic mass-count distinction in different (learner) populations and typologically diverse languages. Although the theoretical distinction between mass and count has been investigated extensively in many different adult languages, experimental research on how this distinction is interpreted by different types of learners and speakers is far rarer. The aim of the current special collection is thus to provide a unique set of highly controlled cross-linguistic and cross-population data that helps us further examine various theories of the syntactic masscount distinction and the interactions between language, cognition and the world.

Much crosslinguistic acquisition research explores finiteness marking in typical development and Specific Language Impairment (SLI). Research into Russian, however, has focused on typical acquisition, not SLI. This article presents a first attempt to investigate finiteness marking in monolingual Russian-speaking children with SLI. We test two competing hypotheses: the Extended Optional Infinitive (EOI) hypothesis and the morphological richness account. The former predicts a large proportion of non-finite forms in the speech of children with SLI crosslinguistically. Due to the rich morphological verbal system of Russian, the latter hypothesis predicts that finiteness marking in Russian SLI will be relatively unimpeded, except for ‘near-miss’ errors. To test these predictions, we analyzed picture-story narrative samples collected from 67 monolingual Russian-acquiring children aged 4;1 to 4;11. All samples are part of the BiSLI corpus created by Tribushinina and colleagues and publicly available through the CHILDES project. We found that, similar to both aged-matched typically developing (TD) controls (N = 24) and younger TD children (N = 23), children with SLI (N = 20) are essentially adultlike in terms of finiteness marking of verbal forms in the matrix clause. The handful of errors observed in the SLI sample involved substitutions in only one inflectional category. These findings provide support for the morphological richness hypothesis over the EOI model of Russian SLI.

The theoretical literature on the mass/count distinction in Palestinian-Arabic (PA) is extremely scarce, and the psycholinguistic perspective has never been explored. In this paper, we report results from an experiment exploring the mass/count distinction in 48 (aged 6;6–17;04) young and adult speakers of PA. Using an adaptation of Barner & Snedeker’s (2005) Quantity-Judgment task, we show that while PA-speaking adults are essentially identical to English-speaking adults, PA-speaking children behave dramatically different from both adult PA speakers and from English-acquiring children. We suggest that these results may reflect a process of language change currently taking place in PA. We further propose two possible sources for the process. The first involves the fact that the grammaticization of mass/count in PA is rather marginal, as indicated by the relative paucity of syntactic structures encoding the distinction. Alternatively, our data may reflect a change process involving a relaxation of obligatory number-marking in cardinality contexts. Finally, we outline a research-program aimed to test these hypotheses.
