Spaced-Word Retrieval as a Vocabulary Teaching Strategy for Children with Hearing Loss

Through this study, we are trying to identify what strategy works best to teach children new words. We will teach children a few words and assess their ability to learn and remember the words. We will do this with children with normal hearing and with children with hearing loss. This information will help us understand how teachers and clinicians can improve vocabulary-teaching practices for children with hearing loss.

Who Can Participate? Participation is completely voluntary.
We are looking for children who:

  1. Have a permanent hearing loss or normal hearing
  2. Are between the ages of 4 and 7 years
  3. Speak English at home
  4. Do not have any developmental concerns in addition to the hearing loss

What’s Involved? Testing is done in the CLHL Lab. Participation requires just 1 visit for 1 hour and 40 minutes and/or 12 visits of 40 minutes throughout 6-9 weeks. During testing, children will be asked to do these things:

  1. Hearing test: To assess how well your child hears (we can give you a copy of the results if you want)
  2. English vocabulary test: To assess how many words your child knows
  3. Non-verbal intelligence quotient: To know the intelligence quotient
  4. Caregiver questionnaire: To learn about your child’s hearing loss and language level

After this testing is done, your child can participate in two different activities. You can select one or you can participate in both.

  • Word learning task: A computer game to learn new words. This activity takes 10 minutes and will be done along with the previous tests during a single visit. The next day, an online post-test will be completed to assess how many words your child remembers.
  • Vocabulary intervention: Your child will participate in a 6-9 week vocabulary intervention. During the intervention, the clinician will teach a few words to your child. You will be able to observe the sessions.

How much will my child be paid? Each child will receive $50 if they participate in the word-learning task and $50 if they participate in the vocabulary intervention. If the child participates in both, he/she will receive $100.
