Cultural Context as a Biasing Factor for Language Activation in Bilinguals

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Cultural context and familiarity are known to influence cognitive processes.
• Understanding how these factors affect bilingual and monolingual language processing is crucial.

Purpose of the Study:

• To investigate the impact of cultural context and familiarity on lexical access in Korean-English bilinguals and English monolinguals.
• To examine event-related potentials (ERPs) during word-picture matching tasks across different cultural congruency conditions.

Main Methods:

• Participants: Korean-English bilinguals and English monolinguals.
• Task: Word-picture matching with culturally congruent (North American/Korean) and incongruent stimuli.
• Measurement: Event-related potentials (ERPs), including N400, and reaction times (RTs).

Main Results:

• Bilinguals showed facilitated responding on culturally congruent trials; ERPs indicated similar processing for both cultures.
• Monolinguals exhibited longer RTs and larger N400 amplitudes for culturally incongruent pairs, indicating increased processing effort.
• Study 2 confirmed that familiarity, not just cultural origin, influenced processing, with monolinguals responding to familiarity and bilinguals to culture.

Conclusions:

• Unfamiliar cultural contexts impede linguistic processing for monolinguals but facilitate it for familiar bilinguals.
• Cultural familiarity plays a significant role in lexical access, differentially affecting bilingual and monolingual processing.
• Findings highlight the interplay between culture, familiarity, and language processing in diverse populations.
