To investigate cross-linguistic lexical and syntactic influences in grammatical gender in early bilingualism, we tested 12 simultaneous, 12 early successive bilingual Russian-German children, and 15 monolingual German children aged 8-9 years. An elicited production task in German shows that all bilingual children assign target gender to nouns,…

This article investigates how lexical and syntactic differences in L1 and L2 grammatical gender affect L2 predictive gender processing. In a visual-world eye-tracking experiment, 24 L1 Russian adult learners and 15 native speakers of German were tested. Both Russian and German have three gender classes. Yet, they differ in lexical congruency, that…

This article offers the author's commentary on the Multiple Grammars (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue. Multiple Grammars advances the claim that optionality is a constitutive characteristic of any one grammar, with interlanguage grammars being perhaps the clearest examples of a…

In two experiments, this article investigates the predictive processing of gender agreement in adult second language (L2) acquisition. We test (1) whether instruction on lexical gender can lead to target predictive agreement processing and (2) how variability in lexical gender representations moderates L2 gender agreement processing. In a…

This article investigates whether and how L2 sentence processing is affected by memory constraints that force serial parsing. Monitoring eye movements, we test effects of working memory on L2 relative-clause attachment preferences in a sample of 75 late-adult German learners of English and 25 native English controls. Mixed linear regression…

In order to identify the causes of inflectional variability in adult second-language (L2) acquisition, this study investigates lexical and syntactic aspects of gender processing in real-time L2 production and comprehension. Twenty advanced to near-native adult first language (L1) English speakers of L2 German and 20 native controls were tested in…

This study investigates ultimate attainment at the syntax-discourse interface in adult second-language (L2) acquisition. In total, 91 L1 (first-language) English, L1 Dutch and L1 Russian advanced-to-near-native speakers of German and 63 native controls are tested on an acceptability judgement task and an on-line self-paced reading task. These…

In order to investigate second language (L2) processing at ultimate attainment, 20 first language (L1) English and 20 L1 Dutch advanced to near-native speakers of German as well as 20 native Germans were tested in two experiments on subject-object ambiguities in German. The results from a self-paced reading task and a speeded acceptability…
