Effect of Variables on Code-Switching Behavior for Bi-dialectal Chinese Speakers

Code-switching, the alternation between two or more languages or dialects in conversation, is a complex linguistic phenomenon influenced by various factors. This study examines how linguistic variables such as linguistic distance, cultural background, proficiency levels, negative relativity, and contextual triggers affect code-switching between local dialects and Mandarin Chinese. Through a quantitative analysis of data from bilingual speakers, the research found that linguistic distance did not significantly affect code-switching frequency, and cultural background showed no clear relationship to switching patterns. Proficiency levels were only vaguely related, indicating that higher proficiency might not consistently decrease code-switching occurrences. Notably, the cognitive control associated with frequent code-switching emerged as a significant factor impacting its frequency. Code-switching was common in short, fixed expressions like slang, proper nouns, interrogatives, and emotive interjections. Additionally, the interlocutors code-switching often triggered a similar response from the other. These findings emphasize the role of contextual and cognitive factors in bi-dialectal communication, highlighting the adaptive nature of language use. The research contributes to understanding the nuanced dynamics of code-switching among bilingual speakers in China, which intends to offer insights into the influence of both social interaction and cognitive control on code-switching behavior.
