We have several research projects for which we are recruiting infants, children, and adolescents. Some studies include children with hearing loss and others include children with normal hearing. Please let us know if you would like more information about any of our studies.

  1. Speech discrimination in young children (0-36 months) with hearing loss. We are studying how young children tell the difference between speech sounds, which affects how they learn to listen and talk. We are looking for children with hearing loss who receive hearing aids or cochlear implants by 30 months. We test the child regularly during the first 9 months of device use. Testing occurs at both the Callier Richardson and Callier Dallas campuses. Sessions last 30-45 minutes for the first session and 15-20 minutes thereafter. We pay participants $20 for each visit.

Speech Discrimination

  1. Vocabulary development in infants and toddlers (1-4 years) with hearing loss or with normal hearing. Many factors affect how children learn words, including their personality. We are examining how a child’s temperament, in addition to factors related to their hearing loss (e.g., when they received their device, how long they have worn it), influences vocabulary size. We pay $20 for this study, which can be completed online.


  1. Quality of life in children and adolescents (10-15 years old) with hearing loss. We continue to explore quality of life in children with hearing loss. Currently, we are asking questions about topics such as friendship, self-esteem, family, and behavior. Participants complete an online survey that takes 20-30 minutes to finish. This study has three different questionnaires so we can include perspectives from the children and adolescents who wear cochlear implants, their parents, and their siblings.

Quality of Life

  1. Communication abilities and device use in children (7-16 years old) with cochlear implants. How do parents and children with hearing loss rate their ability to listen and talk, and how often do these children use their hearing device? Our new study explores how parents and children report daily, functional use with their hearing aid or cochlear implant. We are looking for children and their parents to participate. The online questionnaires take 5-10 minutes for children and 15-20 minutes for parents to complete.

Together, we can learn more about how children with hearing loss develop speech and hearing, as well as how they feel about themselves.
