What to Expect During your Visit (Infants)

How Do We Test Infants?

When you arrive to our lab, a lab member will describe the study. Currently, our infants are tested using a technique known as the observer-based psychophysical procedure. Developed by Lynne Werner at the University of Washington, this procedure uses behavioral responses provided by your baby (such as a head turn to sound) to determine whether they detected or discriminated a target sound.

Infant Testing:OBP2

During the course of this study, your baby will sit on your lap in a sound-proof booth and will listen to sounds. In some studies, the sounds are presented over earphones. In other studies, the sounds are presented via a loudspeaker. To find out what your child can hear, we will teach him/her to make a response to a certain sound signal  by turning on a mechanical toy whenever he/she responses to the sound. The signals will be presented in quiet and in various background sounds.

As part of this study, your child will also receive a middle ear screening. The middle ear screening uses a standard clinical procedure called tympanometry. If at any time we discover any important hearing-related findings, we will report those findings to you and provide you with contact information for a complete hearing evaluation.

When your child is finished with the day's study activities, we will again be happy to answer any questions you have about the study or activities completed. Your child will be paid for their time. Payment for participating ranges depending on type and length of study.
