Developmental Stuttering Lab

Welcome to the Developmental Stuttering lab

The mission of the DS Lab is to investigate the contribution of emotion and language to stuttering and to improve understanding of the mechanism by which emotional and linguistic processes influence stuttering. The lab is directed by Dr. Dahye Choi, who joined the Department of Speech Pathology and Audiology at USA in August 2015. Dr. Choi earned her Ph.D. in Hearing and Speech Sciences from Vanderbilt University.

Sidney McElroy, Graduate Research Assistant

   My name is Sidney McElroy and I am a second-year graduate student in USA’s Speech and Hearing Center. As one of Dr. Choi's graduate assistants, I work weekly in the Developmental Stuttering Lab. My responsibilities include scheduling participant visits, conversing and interacting with participants, administering and scoring speech and language tests,  and conducting hearing screenings. Additionally, I transcribe language samples, record data, and write reports. I am thankful for the opportunity to work in the lab and enjoy working with Dr. Choi and the DS Lab staff!  

Dare Hicks, Graduate Research Assistant


Aryn Clark, Graduate Research Assistant


Hannah Yarbrough, Graduate Research Assistant


Jennifer McDowell, Undergraduate Research Assistant

     I am currently an undergraduate senior majoring in Speech and Hearing Sciences with a minor in Psychology. I serve as Vice President of the National Student Speech Language Hearing Association and VP of the Society of Collegiate Leadership and Achievement at South Alabama. My ambition is to apply to graduate school for a degree in Speech-language Pathology, and later pursue a clinical doctorate in my field. My duties in the Stuttering Lab include entering data and assisting graduate students in giving speech evaluation tests to our participants.

Research

Current Work

Do you wonder if your child shows just normal disfluencies or beginning stuttering? 
Are you and your child interested in participating in research for children with communication disorders?
Then, please consider participating in our study!

We are interested in how children's language abilities and emotional processes influence stuttering and other disfluencies.

Opportunities

Research Participant Opportunities

1) Research project:

Our lab recruits participants between the ages 3-7 years:  children who do and do not stutter.

Visit Procedures for Children

Our testing takes place during two visits (about 1.5-2 hours each). 

During the first visit to our lab, your child will receive a complete speech-language assessment, a hearing test, and participate in play-based conversations. Also, your child will be asked to produce a narrative viewing a picture book. Parents will fill out questionnaires and meet with a certified Speech-Language Pathologist to talk about your child’s speech and language development. 



During the second visit to our lab, your child will participate in an experiment where he/she is asked to put an electrode cap on and watch pictures while passively listening to auditory presentation of words. Preparation for the experiment (i.e., putting a cap on a child) may take about 20 to 25 minutes (the child is allowed to play a video game or play with a toy during the preparation time) and the actual experiment (i.e., viewing visual stimuli and listening to auditory stimuli) may take less than 10 minutes.

This research is funded by University of South Alabama Faculty Development Council. 
Collaborators: 
    Dr.Tara Davis (University of South Alabama)
    Dr.Cyrille Magne (Middle Tennessee State University): https://sites.google.com/site/brainlanguagelab/

Participants can participate in both studies.
It is also possible for participants to participate in the first part of the study (first visit) only. 

Benefits: 
- $ 20 and a guide for parents of children who stutter for the first visit
- $ 30 for the second visit
- Children will be given a small toy after each visit. 
- We will provide a summary report of the speech-language evaluation and place the child in the waiting list of the USA clinic if needed/requested. This speech-language evaluation can replace a formal diagnostic speech-language evaluation for children who stutter provided by the clinic. Also, we can provide a report on the child's temperamental profile based on the Behavioral Style Questionnaire. The questionnaire results will help parents better understand their child and identify areas of needed accommodation.

  

If you are interested in participating in a future research project, please contact the laboratory at (251) 445-9364 or dchoi@southalabama.edu.

Thank you!
We look forward to hearing from you!

Student Opportunities


Volunteer
Volunteering in the lab is a great way to become familiar with the lab and to get hands-on experience with research involving speech and language processing and associated disorders. Volunteers may contribute to the lab in many ways, including but not limited to: stimulus development, data processing, clerical work, and website maintenance. If you are interested in volunteering in the DS Lab, please email Dr. Choi at dchoi@southalabama.edu

News
- Dr.Choi will be presenting her seminar entitled "Counting Disfluencies: the What and the How" at the American Speech-Language-Hearing Association (ASHA) convention in LA in November, 2017.  


- Elizabeth Bemis and Dr.Choi will be presenting their poster entitled "Stress perception and acoustic correlates in child and adult speech" at the USA Undergraduate Student Research Symposium in October 2017.
