The AI and Communication Development Lab (AICDL), led by Yiran Du, focuses on several key research areas aimed at enhancing human communication and language development.

Irony
We explore the cognitive and neural mechanisms of verbal irony comprehension. Our research seeks to understand how individuals process and comprehend verbal irony and how non-linguistic factors affect this process.

Computer-Assisted Language Learning
We investigate how various artificial intelligence tools, such as Duolingo and ChatGPT, can be utilized to improve students' language skills. Our goal is to integrate these technologies into language learning practices to provide effective and accessible education.

Autism
Our research extends to individuals with autism and a range of autistic traits. We examine how these populations comprehend verbal irony and how AI tools can assist in their language development and communication skills.

Techniques
We employ a variety of research techniques, including behavioral measures, EEG, fMRI, questionnaires, interviews, and focus groups. These methods allow us to gather comprehensive data and insights into language comprehension and learning processes.

Objectives
Our primary aim is to understand how both typical and autistic individuals comprehend verbal irony. Additionally, we strive to design computer-assisted interventions to improve communication skills in both first and second languages. By leveraging our research findings, we seek to develop effective educational tools and strategies that support language learning and communication for diverse populations.
