Flanker Task Performance In Young And Older Adults: A Behavioral And Erp Study, Fatima Medrano

Dissertations, Theses, and Capstone Projects

Research suggests that as we get older, executive function abilities decline (Hasher & Zacks, 1988; Salthouse, 1996). One affected ability is that of inhibitory control, which aids in monitoring our responses to non-target stimuli or information. Current research on inhibition reveals inconsistencies across studies. Monitoring brain responses during the Flanker (used to measure inhibitory control) task may add valuable insight into the processes underlying group differences behaviorally, by studying the N200 and P300 event-related potentials which have been associated with inhibitory control processes. This study investigated whether there are differences between older and younger adults in inhibitory control and whether …

Exploring Cross-Linguistic Speech Perception In Hindi, English, And Romance-Language Through Temporal Dynamics Of Neural Activity, Yuga Kothari

Dissertations, Theses, and Capstone Projects

This study examines the effect of linguistic experience on the neural processing of Voice Onset Time (VOT) in Hindi and Romance language (Spanish and Portuguese) individuals who are bilingual in English and monolingual English speakers using the event-related potential (ERP) Mismatch Negativity (MMN) response. VOT is a linguistic property that measures the time elapsed between the release of a stop consonant and the beginning of voicing, that is, vocal fold vibration of a following vowel. In a double-oddball paradigm, participants’ (n = 41) ERP were recorded while listening to speech sounds differing in VOT. The bilabial short lag stop [p] …

Association Strength Between Concepts As The Origin Of The "Foreign Language Effect", Emilia Ezrina

Dissertations, Theses, and Capstone Projects

Bilinguals sometimes make decisions in verbal tasks differently in their first (L1) and second (L2) language. This phenomenon is known as the foreign language effect (FLE), and it suggests strong connections between language and cognition. On the one hand, it is possible that L2 “blunts” emotional language. However, the FLE can be observed in non-emotional tasks. Therefore, it is possible that L2 requires more deliberate processing due to increased cognitive load, leading to more rational decisions. The support for each explanation is mixed.

In this thesis we propose looking for a single explanation for all instances of the FLE. After …

The Relative Cost Of Codeswitching: An Electrophysiological Study Contrasting Language Switching Versus Lexical Predictability, Iris Strangmann

Dissertations, Theses, and Capstone Projects

Neurophysiological sentence processing studies are inconsistent about the additional costs that language switching within sentences (i.e., codeswitching) may bring about (cf. Valdés Kroff et al., 2020; Yacovone et al., 2021). There is discussion about whether there are, in fact, additional costs and, if so, about the origins of those costs, since some findings are consistent with effortful processing when comprehending single-language (not switched) words observed in monolingual studies. Specifically, studies are divided on whether codeswitched words are more difficult to lexically access than single-language equivalents of similar semantic predictability, as indexed by an increased N400 effect. The same studies, however, …

Phonetic Contrast In New York Hasidic Yiddish Vowels: Language Contact, Variation, And Change, Chaya R. Nove

Dissertations, Theses, and Capstone Projects

This study analyzes the acoustic correlates of the length contrast in New York Hasidic Yiddish (HY) peripheral vowels /i/, /u/, and /a/, and compares them across four generations of native speakers for evidence of change over time. HY vowel tokens are also compared to English vowels produced by the New York-born speakers to investigate the influence of language contact on observed changes. Additionally, the degree to which individual speakers orient towards or away from the Hasidic community is quantified via an ethnographically informed survey to examine its correlation with /u/-fronting, a sound change that is widespread in the non-Hasidic English-speaking …

Cross-Linguistic Morphosyntactic Influence In Bilingual Speakers Of Jamaican Creole And Jamaican English, Taryn R. Malcolm

Dissertations, Theses, and Capstone Projects

Bilingualism in Jamaica is of considerable consequence, as most individuals are early bilinguals, speaking both a variety of Jamaican Creole (JC) from birth and having standardized English (sE) as the language of instruction in education. Immigrants from Jamaica to the United States are an ideal population to examine how cross-linguistic influence (CLI) impacts morphosyntax as JC and sE differ in morphosyntactic constructions, including verb tense- marking, subject-verb agreement, and copula use. While much of the work in the field of CLI has examined spoken language pairs with varying degrees of similarity (or difference) between the languages, examining CLI in a …

Testing The Perceptual Magnet Effect In Monolinguals And Bilinguals, Michael C. Stern

Dissertations, Theses, and Capstone Projects

Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual distance between themselves and neighboring stimuli in the same category. This phenomenon has been termed the ‘perceptual magnet effect’ (PME). The present study extends work on the PME to a speech sound category previously unstudied in this paradigm (American English /æ/), and to bilingual speech sound representation and perception. American English monolinguals and Turkish-English bilinguals completed identification tasks, category goodness rating tasks, and same-different discrimination tasks with synthesized vowel sounds from the American English /æ/ category—not …

Heritage Speaker And Late Bilingual L2 Relative Clause Processing And Language Dominance Effects, Leeann S. Stevens

Dissertations, Theses, and Capstone Projects

Traditionally, heritage speakers are recognized as a heterogeneous group whose skills in their heritage language are unlike those of monolinguals or L2 learners of that language. Indeed, much evidence confirms the cognitive and linguistic uniqueness of this population. However, highly proficient heritage speakers may pattern more similarly to another bilingual population than typically assumed: first-generation late bilinguals.

The present study examines group-level processing differences between Spanish heritage speakers and Spanish-English late bilinguals in English, the second-learned and current societal majority language of these populations. Dominance is also analyzed as a possible effect of group processing differences, since traditionally and definitionally …

Language Access In Early And Late Spanish-English Bilinguals: An Erp Study, Lissete Gimenez-Arce

Student Theses

Research suggests that code-switching between two languages is possible because there is nonselective access to both languages, i.e., both languages are interdependent and stored in a shared lexicon. In this study, we used event-related brain potentials (ERPs) to measure the neural processes associated with language access, in particular, the ERP components: N200 and N400. Although previous studies have utilized these ERPs to investigate language access using interlingual homographs, i.e., words that look the same in two languages but have different meanings, these have focused on comparisons of monolingual and bilinguals. In contrast, we used a design that looked at Spanish …

Mandarin Assessment In Chinese-English Bilingual Preschoolers, Jennifer A. Chard

Dissertations, Theses, and Capstone Projects

Immigrant children who grow up in linguistically and culturally diverse households are at risk for misdiagnosis for language impairment and inappropriate placement in or exclusion from special education classes. Research shows that native language testing is essential in determining eligibility for disability services, as reflected both in federal law (Individuals with Disabilities Education Improvement Act of 2004). However, despite growing agreement that native language assessment is a critical component to understanding the abilities and challenges bilingual students face, the standard assessments currently used are largely administered in Standard English and normed on monolingual English speakers. Few options are available to …

Syntactic Processing And Cross-Linguistic Structural Priming In Heritage Spanish Speakers And Late Bilinguals: Effects Of Exposure To L2 English On Processing Illicit Structures In L1 Spanish, Ian Phillips

Dissertations, Theses, and Capstone Projects

This study examines real-time heritage language syntactic processing and tests the hypothesis that some commonly observed properties of heritage languages—apparent instability in grammatical knowledge and divergence from monolingual grammatical norms—can be attributed to cross-linguistic influence from the socially dominant language during online processing. To test this hypothesis, a novel cross-linguistic structural priming experiment based on self-paced listening was conducted with a group of heritage Spanish speakers and late Spanish-English bilinguals to test whether exposure to preposition stranding in English—a feature of core syntax that does not exist in Spanish—could facilitate processing of (ungrammatical) preposition stranding in a subsequently encountered Spanish …

De-Centering The Monolingual: A Psychophysiological Study Of Heritage Speaker Language Processing, Christen N. Madsen Ii

Dissertations, Theses, and Capstone Projects

Models of grammar, processing and acquisition are primarily built on evidence from monolinguals and adult learners of a second language. Heritage speakers, who are bilinguals of a societal minority language, acquire and use their heritage language in informal settings; but who live, work, and are educated in the societal majority language. The differences between heritage speakers and both monolinguals and adult second language learners are extensive: heritage speakers are not educated in the heritage language, their input is typically not from a prestige variety of the heritage language, and they are dominant in the majority language, using it more frequently …

A Playful Context Enhances Bilingual And Monolingual Preschoolers’ Mastery Motivation And Private Speech, Jeremy Sawyer

Dissertations, Theses, and Capstone Projects

Children’s private speech (audible self-talk) has been studied primarily as a cognitive tool for thinking, planning and self-regulation. This study investigated whether private speech may also function as a tool for motivation. Vygotskian and self-determination theory suggest that children can develop to become agentic and inspired, or conversely disengaged and alienated, based largely on their social conditions of development. Thus, it is important to investigate children’s motivational processes in social and educational contexts that are central to child development. U.S. preschool enrollment is expanding, accompanied by a decline in play-based pedagogy and growth of didactic, teacher-centered approaches. To illuminate the …

Native Language Adaptation To Novel Verb Argument Structures By Spanish-English Bilinguals: An Electrophysiological Investigation, Eve Higby

Dissertations, Theses, and Capstone Projects

Bilinguals have to learn two different grammatical systems. Some aspects of these grammars may be similar across the two languages (for example, the active-passive alternation) while others may exist in only one of the two grammars (for example, the distinction between recent and distant past). This dissertation investigates the degree to which grammar information specific to only one language is available when processing the other language. In particular, the current study focuses on the application of grammatical structures from the bilinguals’ second-learned language to their first-learned language, a direction of language transfer not often investigated. Based on a Shared Syntax …

Literacies Of Bilingual Youth: A Profile Of Bilingual Academic, Social, And Txt Literacies, Michelle A. Mcsweeney

Dissertations, Theses, and Capstone Projects

This dissertation identifies three types of language skills that urban Spanish/English bilingual youth possess (academic, social, and texting language), and reports on their relationship while documenting and analyzing the features of text messaging among this population. The participants in this study are Spanish-dominant bilingual young adults enrolled in a high school completion program in New York City. They are in the process of developing both Spanish and English academic literacy skills, and it is well known that they tend to perform below the grade they are enrolled in. For this reason, they are often referred to as being “language-less” (DeCapua …

Re-Examining The Bilingual Advantage On Interference-Control And Task-Switching Tasks: A Meta-Analysis, Seamus Donnelly

Dissertations, Theses, and Capstone Projects

A much-debated topic in psycholinguistics is whether lifelong bilingualism enhances executive functions (EF), the set of higher-order cognitive processes involved in the control of thought and action. Several researchers have predicted bilingual advantages on various EF tasks, especially interference-control and task-switching tasks. Many studies have tested these predictions, but results have proven unreliable. As a complementary approach to recent quantitative syntheses on this topic, the present dissertation tests whether the bilingual advantage is moderated by a number of theoretically significant variables: dependent variable (DV), task, age, age of L2 acquisition and lab.

Two meta-analyses were conducted. Study 1 considered interference-control …

Neurophysiological Correlates Of English Vowels /I/ And /E/ In Monolingual And Bilingual 4 And 5-Year-Old Children, Nancy Vidal

Dissertations, Theses, and Capstone Projects

Second language (L2) input in the infant and toddler years clearly affects speech processing, particularly for L2 vowels (Cheour, Shestakovab, Ceponieneb, Näätänen 2002), Moreno, Rodriguez-Fornells, Matti, 2008); Rinker, Paavo, Brosch, Kiefer 2010). However, few studies have closely examined how amount of L1 versus L2 input impacts automaticity of speech processing in young children. Greater language use of one than the other language promotes improved speech perception and production in the language of greater use (Flege & Munro 1994; Flege & MacKay 2004). Investigations have used a variety of custom-designed questionnaires to quantify amount of language use, but most have not …

The Emergence Of L1 Innovations In Spanish-English Bilinguals: Evidence From Cross-Linguistic Structural Priming, Agustina Carando

Dissertations, Theses, and Capstone Projects

This dissertation explores the hypothesis that structural priming is an internal mechanism motivating processes of convergence in bilinguals. The focus of the investigation is linguistic innovations in Spanish produced by Spanish-English bilinguals. Innovations involve both changes in the frequency of alternative constructions and existing patterns produced in new contexts modeled on English equivalents. From structural priming techniques that model convergence, the data assess the extent of English influence on Spanish, in a contact setting (New York, United States) and a non-contact setting (Córdoba, Argentina).

In the field of language contact, convergence may manifest itself as an increase in the use …

Consonantal Voicing Effects On Vowel Duration In Italian-English Bilinguals, Ylana Beller-Marino

Dissertations, Theses, and Capstone Projects

This project reported in this dissertation analyzes phonetic details of the speech patterns in one of New York's bilingual communities, asking whether a bilingual speaker can attain native-like proficiency in both languages and the extent to which authenticity — maintenance of language-specific settings — is sustainable. Researchers have established that Italian and English differ strikingly in their characteristic time settings for vowel durations: durations are greater for vowels preceding voiced consonants, e.g., cab, rather than voiceless, e.g., cap. This duration difference, termed the consonantal voicing effect (CVE), is notably greater for English than for Italian. The greater magnitude …

Guatemalan Spanish As Act Of Identity: An Analysis Of Language And Minor Literature Within Modern Maya Literary Production, Kenneth Yanes

Dissertations, Theses, and Capstone Projects

My study approaches the use of Guatemalan Spanish in modern Maya literary works through a theoretical framework drawn on theories of "purity" and mestizaje, the concept of minor literature, and "image" and ideology of language. I problematize the "major"/"minor" dichotomy of language based on a Eurocentric view of the dominance of national languages as the extremely diverse linguistic ecology of Latin American lends itself to the deterritorialization of hegemonic discourse, but without sustaining a neat categorization of language. Guatemalan Spanish is a heavily Maya-inflected interlanguage share by all Guatemalans. Mayan writers chose purposefully to counter the ladino ethnocentrism of the …
