Processing Of Diphthongs By Turkish English Bilinguals: An Erp Study, Ecem Kopuz
Processing Of Diphthongs By Turkish English Bilinguals: An Erp Study, Ecem Kopuz
Dissertations, Theses, and Capstone Projects
This study examines how native phonological experience influences the brain’s response to speech sounds in Turkish-English late bilinguals and English monolinguals. We asked whether neural responses reflecting encoding of auditory information would be sensitive to language specific experience. Using event-related potentials (ERPs), and specifically, the Acoustic Change Complex (ACC) we measured neural responses to four stimuli, /u/, /ua/, /iu/, and /ia/, where vowel quality changes for three of these. A change from /u/ to /a/ or /i/ to /a/ within a syllable (as in [ua] and [ia]) represents a clear vowel quality shift. All participants were expected to show sensitivity …
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] …
Neurophysiological Correlates Of English Vowels /I/ And /E/ In Monolingual And Bilingual 4 And 5-Year-Old Children, Nancy Vidal
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 …
Development Of A New Experiment Demonstrating Categorical Perception, Kelsey Montzka
Development Of A New Experiment Demonstrating Categorical Perception, Kelsey Montzka
Student Research Initiative
In this project, we have created an online portal containing a multi-faceted demonstration of categorical perception. We utilized the 2I2AFC (two-interval, two alternative forced choice) stimulus presentation method which should elicit more categorical results from students, helping to better demonstrate the phenomenon (Gerrits & Schouten, 2004), and provided different acoustic cues illustrating CP. In addition to illustrations of CP for F2 formant transition, the new online portal is used to illustrate voice onset timing (VOT; the cue that distinguishes between the sounds [b] and [p]), as well as how contextual factors and participants’ linguistic backgrounds affect CP. The contextual factors …
