Research focus
Si On Yoon’s research in the Iowa Communication, Memory, and Mind Lab take a cognitive science approach to the study of complex language processes. Her research contributes to understanding the neural and cognitive mechanisms that support conversation across the lifespan, including how interlocutors use language, and how memory and language interact to support conversational processes. She has developed an experimental paradigm to study conversation in the lab and used methods such as eye-tracking and measurement of event-related potentials during a task-based conversation among 2-7 conversational participants. She is also interested in how the ability to use social-pragmatic cues during language processing develops and how this ability varies across populations, especially those who may have severe memory impairment (e.g., older adults, individuals with neurodegenerative disease (e.g., Alzheimer’s disease)).
