BIO


My name is Carson DaSilva, I am an sophomore studying economics and I am from Tallahassee Florida. I am heavily interested in research involving human decision making and thought processing. This project involved peoples natural gravitation for certain sounds to words regardless of region or language. I hope to use this research project as a solid basis for future research endeavors in my career.

Abstract


This study investigates how linguistic background influences the semantic attribution of novel speech sounds by comparing how Spanish-English bilinguals and English monolinguals perceive pseudowords. We use a corpus of pseudowords that are categorized into neutral, sharp, and round phonetic groups and established a baseline of English-centric word associations using ChatGPT. The current phase of the project utilizes Qualtrics surveys to collect responses from human participants to determine if Spanish-English bilinguals attribute different meanings or emotional valences to these pseudowords compared to monolinguals. We specifically examine whether bilinguals associate these sounds with real words in their secondary language due to phonetic or morphological similarities, acting as interlingual homophones. By analyzing these cross-linguistic associations, the research aims to uncover how a secondary lexicon provides a unique filter for processing novel language and whether these associations override universal sound-symbolic patterns.
