Auditory Event-Related Potentials (AERP) Lab

About the Auditory Event-Related Potentials (AERP) Lab

Welcome to the AERP lab directed by Dr. Tara Davis. In this lab, we use electrophysiological measures to collect brainwaves related to auditory and cognitive processing. This lab has been primarily focused on age-related differences in AERPs; however, our recent projects have also investigated the AERPs of individuals with traumatic brain injury (TBI) or those who stutter.

Current Projects

Cortical Associates of Semantic Processing in Children who Stutter

    • The purpose of this study is to determine whether, at a cortical/neural level, there is atypical semantic integration and/or lexical access in children who stutter as compared to children who do not stutter.

    • Participant Requirements:

      • Between the ages of 3-7 years

      • Children who do and do not stutter

    • Primary Investigators: Dr. Dahye Choi/Dr. Tara Davis

    • This project is in conjunction with the Developmental Stuttering Lab lead by Dr. Choi. Please refer to their lab website for more information.
