CE Course Overview

About the Young Researchers Series Courses

The purpose of this series is to share recent research in stuttering, specifically by giving a platform to today’s younger researchers, who will be leading the field in the future. The series features speakers who have completed their PhD in the past 5 years.

The format consists of a video interview discussing highlights and clinical implications of their work. The goal of this series is to help SLPs stay up to date on current research in stuttering.

Course Content

This course features an interview with Dr. Evan Usler who discusses the motor and emotional aspects involved in the development of stuttering. Dr. Usler presents his research on speech motor coordination, emotional reactivity, and stuttering persistence. Clinical implications and future work are discussed. 

Learning Outcomes

Participants will be able to:

  • Define the multifactorial dynamics pathways theory
  • Explain how emotional and linguistic demands can impact the speech motor system and how this impacts stuttering variability
  • Define EMGs and explain how they can be used in stuttering research 


Run-time: 49:30

Interviewer questions:

  • How did you become interested in stuttering research?
  • Tell me about your research.
  • Tell us about the multifactorial dynamic pathways theory of stuttering.
  • How do all of these factors interact to contribute to stuttering?
  • How can SLPs use this information in their assessment and treatment of stuttering?
  • How do people who stutter really change their speech motor habits?
  • What is your advice to an SLP or parent who may be listening to this and thinking that it’s just a matter of making adjustments to the speech motor system for their client/child to be fluent?
  • What are the next steps in your research?
