Language Control Across Modalities

This study aims to investigate how unimodal bilinguals who speak two languages and bimodal bilinguals who speak one language and sign another control languages across comprehension and production. Participants will complete different language tasks (e.g., classify a word, name a picture) in different languages, and their behavioral performance will be assessed, including accuracy and reaction time.
