Extra Credit Research Participation

Some of the undergraduate classes in the Department of Communication Sciences and Disorders offer extra credit for participation in research. Each course outlines the terms (number of hours per credit) in the syllabus. If you are unsure, contact your instructor.

All studies are approved by the University of Wisconsin’s Human Subjects IRB, and participants will be asked to sign consent forms prior to the study.

To participate, CONTACT THE LAB (not your instructor). The LAB will arrange a time with you at a time that is mutually convenient.

After the study, students will select which course they wish to allocate credit for, and the lab will document the participation. At the end of the semester, the lab will forward a list of names of students who participated to each instructor, for credit allocation. Students are also encouraged to save a copy of the consent form and write down the date and number of hours of participation for additional proof of participation.

How does the brain control the ear?

Efferent Systems Laboratory
Sriram Boothalingam, Ph.D., FAAA
Viji Easwar, Ph.D., FAAA
Description: Following a hearing screening, you will be asked to listen to sounds through earphones. Your brain and ear responses will be measured using otoacoustic emissions (OAE; sounds generated by your ear) and electroencephalography (EEG). You can watch a silent closed caption movie/video of your choice during the experiment. You will also be asked to wear a discrete sound measurement device for a day to measure sound levels in your day-to-day life.
Participation Criteria: 1) Between 18-35 years of age; 2) Normal hearing; 3) No known disabilities or neurological conditions (e.g., seizures)
Participation Time Required: ~2-3 hours (two sessions, 4 weeks apart)
Recruitment Time Frame: Ongoing
Contact Information: If interested, please contact efsylab@waisman.wisc.edu to schedule a session. Please include “Brain Ear Study” in your subject.


How does noise affect the brain’s response to speech?

Efferent Systems Laboratory
Sriram Boothalingam, Ph.D., FAAA
Viji Easwar, Ph.D., FAAA
Description: You will be asked to repeat the colours and numbers presented in the presence of noise through earphones. Brain activity in response to speech sounds will be measured with 3 to 4 surface stickers (electroencephalogram) while you watch a silent closed caption movie/video of your choice. We will determine eligibility through a hearing screen.
Participation Criteria: 1) Between 18-35 years of age; 2) Normal hearing; 3) No known disabilities or neurological conditions (e.g., seizures)
Participation Time Required: ~2-2.5 hours (one session)

Contact Information: If interested, please contact efsylab@waisman.wisc.edu to schedule a session. Please include “Speech in Noise” in your subject.


How does the shape of the ear affect brain encoding of speech-like sounds?

Efferent Systems Laboratory
Sriram Boothalingam, Ph.D., FAAA
Viji Easwar, Ph.D., FAAA
Description: Brain activity in response to speech-like sounds will be measured with 3 to 4 surface stickers (electroencephalogram; EEG) while you rest or sleep. We will determine eligibility through a hearing screen.
Participation Criteria: 1) Between 18-35 years of age; 2) Normal hearing; 3) No known disabilities or neurological conditions (e.g., seizures)
Participation Time Required: ~1.5-2 hours (one session)
