How bilinguals control language when listening, speaking, and signing

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will recruit unimodal bilinguals (Mandarin–English) and bimodal bilinguals (ASL–English) and have them perform language tasks such as categorizing words and naming pictures in different language contexts. Experimental manipulations will vary predictability and language context while measuring accuracy and reaction time on comprehension and production tasks. The study compares behavioral performance across modalities to see how language control operates for spoken–spoken versus spoken–signed bilinguals. Participants with third-language dominance or neurological/language disorders are excluded to keep the sample focused on healthy, proficient bilinguals.
