Publications and Research

Objectives: To examine maturation of neural discriminative responses to an English vowel contrast from infancy to 4 years of age and to determine how biological factors (age and sex) and an experiential factor (amount of Spanish versus English input) modulate neural discrimination of speech.

Design: Event-related potential (ERP) mismatch responses (MMRs) were used as indices of discrimination of the American English vowels [ε] versus [I] in infants and children between 3 months and 47 months of age. A total of 168 longitudinal and cross-sectional data sets were collected from 98 children (Bilingual Spanish–English: 47 male and 31 female …

Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …
