Do adult L2 English bilingual speakers have difficulty with cognate words whose meanings are distinct across their two languages? This study explored the extent to which variations in meaning in cross-language cognates affect translation performance in a translation task by L2 English (L1 Spanish) speakers who learned English as adults. A prep-phase experiment was conducted to test native English-speakers’ predicted completions of the study’s stimuli sentences, in order to choose the optimal stimuli for the primary experiment. The method for the primary experiment of this study consisted of a web-based translation task of 120 sentences from Spanish to English, while controlling for polysemy and frequency. The results showed that adult L2 learners of English did experience difficulty when translating cognates in sentences from their L1 to their L2. The interaction of the Spanish word’s polysemous nature, Spanish word frequency, English target frequency and English cognate frequency played a role in the participants’ performance.

The primary focus of this research was to investigate the emotion language and emotion narratives of Turkish-English late bilinguals who have been living in the U.S. Previous research has shown that the emotion language and narratives of second language learners and native speakers of English are different. This study focused on late bilinguals who had learnt English in instructed settings in their home country, and came to the U.S. for M.A. and Ph.D. degrees. The study consisted of two parts. In the first part, the elicited personal narratives of Turkish-English late bilinguals in English were compared to those elicited from native speakers of English with regard to both emotion and emotion-laden word production and narrative structure. The results showed that there were differences between the emotion language and narratives of the bilinguals and native speakers in their English narratives. In the second part of the study, personal narratives were elicited from Turkish-English late bilinguals in their first language, Turkish and their emotion language and narrative structure from their English narratives were compared to their narratives produced in Turkish. Similarly, the results showed that the emotion language and emotion narratives of bilinguals in English and Turkish were different. In conclusion, late bilinguals' emotion language and narratives are different in their first and second languages. Furthermore, they are different from the emotion language and narratives of native speakers.

Diese Dissertation untersucht Transfereffekte aus der Muttersprache (L1) in der Verarbeitung von grammatischem Genus in der Zweitsprache (L2) bei Spätbilingualen. „Spätbilinguale“ lernen eine Zweitsprache nach der Kindheit, im Gegensatz zu „Frühbilingualen“. Forschungsergebnisse zeigten, dass der L2-Erwerb nach der Kindheit weniger erfolgreich ist als während der Kindheit und dass einige Strukturen, wie z.B. grammatisches Genus, besonders stark von Alterseffekten beeinträchtigt sind. Eine Erklärung für L2-Verarbeitungsschwierigkeiten ist negativer L1-Transfer. Deshalb konzentriert sich diese Dissertation auf L1-Transfereffekte in der Genusverarbeitung. Transfer tritt auf, weil alle Sprachen eines Sprechers aktiviert sind und im Wettbewerb um Selektion stehen. Ein Ziel dieser Dissertation ist, zu beschreiben, welche Faktoren Genustransfer beeinflussen. Für die L2-Genusverarbeitung wurde gezeigt, dass verschiedene Faktoren die Leistung beeinflussen, z.B. die L2-Kompetenz der Probanden, Aufgabenanforderungen und die syntaktische Distanz der übereinstimmenden Elemente. Genustransfer wird durch Faktoren wie Charakteristiken des L1-Genussystems, Transparenz des L2-Genussystems und Formähnlichkeit der Nomen in L1 und L2 beeinflusst. Außerdem könnte Genustransfer von der L2-Kompetenz und der Komplexität des L2-Genussystems abhängen. Es wurden ein behaviorales und ein EKP-Experiment durchgeführt. Genustransfer wurde über verschiedene Sprachpaare mit Genussystemen von unterschiedlicher Komplexität und Transparenz hinweg untersucht. Die experimentellen Aufgaben unterschieden sich bezüglich der Aufgabenanforderungen und syntaktische Strukturen mit unterschiedlicher struktureller Distanz wurden verwendet. Der Leistungsstand der Probanden wurde manipuliert. Anhand meiner Ergebnisse konnte ich identifizieren, welche (Kombination von) Faktoren Genustransfer erhöhen oder verringern und Genustransfer als das Ergebnis eines komplexen Wechselspiels von Faktoren beschreiben. / This thesis investigates first language (L1) transfer effects in second language (L2) grammatical gender processing of late bilinguals. “Late bilinguals” learn an L2 after childhood, in contrast to “early bilinguals”. Research has shown that L2 acquisition after childhood is usually less successful than during childhood and that some aspects of a language are more affected by age than others. One of the structures especially affected is grammatical gender. A possible explanation for L2 processing difficulties in late bilinguals is negative transfer from the L1. Therefore, this thesis focuses on L1 transfer effects in L2 gender processing of late bilinguals. Transfer arises because all languages of a speaker are activated and compete for selection. One aim of this thesis is to describe which (combination of) factors influence L1 gender transfer. Regarding L2 gender processing in general, different factors have been shown to affect performance, e.g., language proficiency of the subjects, task demands, and syntactic distance of the agreeing elements. Gender transfer is affected by factors such as characteristics of the L1 gender system, transparency of the L2 gender system, and form similarities of nouns in L1 and L2 (cognates vs. noncognates). Besides this, gender transfer might be mediated by L2 proficiency and the complexity of the L2 gender system. In this thesis, a behavioral and an ERP experiment were conducted. Gender transfer was investigated across different language pairs with gender systems of varying complexity and transparency. Experimental tasks differed in task demands and syntactic structures with varying agreement distances were used. Language proficiency of subjects was also manipulated. Based on my findings, I was able to identify which factors and which combination of factors increase or decrease gender transfer and to describe gender transfer as the result of a complex interplay of a combination of various factors.
