Researchers in various studies looking for participants

Here is a list of research studies that currently are looking for participants.

 

Study on how brain processes pitch of a sound

Adults ages 18-55 with mild-moderate hearing loss are needed for a study to evaluate how sounds are processed in the human brain. The procedure consists of recording electrical activity from the brain (using five EEG-type electrodes attached to the head and ear) in response to various sounds presented through earphones at comfortable listening levels.

The task is to sit, relax on a comfortable chair situated in a sound-treated booth, and watch a muted video from a film library. Participants will be asked to fill out forms before the actual experiment. Participants will be paid $25 per two-hour session. Participants may be required to attend two to four sessions. The study will be performed in the Auditory Electrophysiology Lab in Lyles-Porter Hall, Room 3043.

Participants must be/have:

  • 18-55 years old.
  • Right-handed.
  • No musical training or less than three years of musical training.
  • No previous history of brain injury or psychiatric problems.
  • Mild-moderate hearing loss in at least one ear.

The principal investigator is Ananthanarayan Krishnan, professor of speech, language, and hearing sciences. Individuals who meet the prescreening criteria listed above and are interested in volunteering for the study should contact Aditi Gargeshwari at agargesh@purdue.edu. IRB#: 506002731.

Study on how the brain combines sight and sound

Boys and girls ages 8-12 are needed for a study on how the brain combines sight and sound.

During the last six sessions, children’s brain activity will be collected while they are doing different tasks. Brain wave recording sessions are structured as games. Brain waves will be collected with the help of a special cap with built-in electrodes (similar to EEG recordings). There is no discomfort involved, and the method has been safely used with infants, children and adults.

To participate, children must be 8-12 years old; typically developing; right-handed; native speakers of American English; free of speech, language, hearing/vision or neurological disorders and conditions such as autism/Asperger’s, head injuries, seizures, brain tumors, cerebral palsy, ADHD, stuttering and depression; and not currently on medications that may affect brain activity (e.g., medications to control ADHD, seizures or depression).

Children will be compensated $10 per hour and will receive a small toy (worth approximately $5) at the end of each session. Parents also will be paid $10 per session. Evening and weekend sessions are available, if needed.
