This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

Although previous research has observed a facilitative influence of the first language (L1) on the acquisition and processing of gender agreement in a second language (L2), particularly in language pairs with similar gender agreement marking, the question of whether knowledge of two languages with gender can confer an additional advantage for…

Quantificational elements such as some pose a challenge to young language learners, given their vague meaning and ability to take on an upper-bounded interpretation (relative to "all") in certain contexts. The challenge is enhanced when a child is acquiring multiple languages that do not share a one-to-one mapping between their lexical…

Traditionally, transfer is described as interference and consequently as an unintentional mechanism. More recently, however, the perception of control in transfer has changed and it is now commonly accepted that transfer can occur both automatically and strategically. Studies have previously employed think-aloud protocols during writing tasks to…

This study investigates grammar learning strategies and the acquisition of L2 tense-aspect morphology through the retrospective think-aloud processes of a group of L3 learners of Catalan. A total of 18 students of Catalan in a university setting in Catalonia were asked to select one of three tense-aspect forms (preterite, imperfect, and perfect)…

In this study, we present and analyze co-constructions from L2 English data collected at the European School in Luxembourg. Co-constructions are morpho-syntactic structures split across two speakers, in which a second speaker completes a grammatical structure initiated by the first speaker in conversation. The corpus features multilingual 13-14…

The scrambling complexity hypothesis based on working memory or locality accounts as well as syntactic accounts have proposed that processing a scrambled structure is difficult. However, the locus of this difficulty in sentence processing remains debatable. Several studies on multiple languages have explored the effect of scrambling on sentence…
