Official title

Language Control Across Comprehension and Production in Unimodal and Bimodal Bilinguals

Overview

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.

Interventions

  • Behavioral Predictability
    Whether the task of the next trial (comprehension or production) is predictable
  • Behavioral language context
    whether both languages or only one language is involved in the current block

Primary outcome measures

  • Switch costs in different contexts [Time frame: An average of one year for each condition]

Eligibility criteria

Inclusion criteria

  • Proficient in both Mandarin and English, or proficiency in both ASL and English

Exclusion criteria

  • With language disorder or other neurological disorders
