In two visual-world eye-tracking experiments, we explore the extent to which conflicting first-language (L1) based grammatical parses influence second-language (L2) learners' on-line and off-line interpretation of sentences in the L2. We used cross-linguistic structural priming to potentially boost competition from the L1 grammar during the…

This article explores how multiple linguistic cues interact in predictive processing among second language (L2) learners. In a visual-world eye-tracking experiment, we investigated whether learners of German use case and prosody cues together to assign thematic roles and predict post-verbal arguments. During the experiment, participants listened…

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 reports two intervention studies testing the effects of plurilingual teaching on grammatical development among primary-school students learning English as a foreign language (FL). In a pre-posttest control-group design, more than 200 9-10-year old majority language German and minority language students received plurilingual FL…

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 paper reports findings of a project on pedagogical translanguaging (PTL) among 128 fourth-grade students learning English as a foreign language (EFL) in German primary schools. Over a period of six months, 20% of lesson time in EFL classes was devoted to multilingualism involving students' minority languages. In a control group pre-post-test…

This article reports an eye-tracking study on the native and non-native processing of case in Spanish. Twenty-four native and 27 first language (L1) German non-native speakers of Spanish were tested on their sensitivity to case marking violations involving structural case with objects of ditransitive verbs and to violations of inherent case for…

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…

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…
