Brief summary
The goal of this basic experimental study involving humans (BESH) clinical trial is to examine how stimulus length affects grammar learning in children who are deaf or hard-of-hearing and who primarily use spoken language. The main question it aims to answer is: do short or long stimuli better support grammar learning in this population? Participants will complete an artificial grammar learning task to see which condition (short vs. long stimuli) results in better grammar learning.
Interventions
BEHAVIORALShort linguistic content
Grammar-like auditory stimuli will comprise short linguistic content.
BEHAVIORALLong linguistic content
Grammar-like auditory stimuli will comprise long linguistic content.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy on third grammaticality judgment test | End of day 2 of the artificial grammar learning task | Participants will be presented with novel, grammar-like auditory stimuli. They will decide whether each stimulus matches or does not match the artificial language that they were previously presented with. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy on first grammaticality judgment test | Middle of day 1 of the artificial grammar learning task | Participants will be presented with novel, grammar-like auditory stimuli. They will decide whether each stimulus matches or does not match the artificial language that they were previously presented with. |
| Accuracy on the second grammaticality judgment task | Start of day 2 of the artificial grammar learning task | Participants will be presented with novel, grammar-like auditory stimuli. They will decide whether each stimulus matches or does not match the artificial language they were presented with previously. |
