Study Overview
Brief Summary
This study examines the development of American Sign Language by deaf and hard of hearing (DHH) children and their parents.
Detailed Description
After being informed about the study and potential risks, adult participants who give written informed consent and children whose parents who give written permission will be enrolled in the study. They will participate in preliminary language tasks to assess baseline performance on American Sign Language (ASL) measures. Subsequently they will have weekly sessions with an ASL Specialist to support their development of ASL, following a 6-week on/6-week off ABABABAB sequence.

Arms & Interventions
ASL Services - Adult ASL Development
Presence (or absence, across 6-week periods) of ASL services designed to support improvement in ASL fluency
Intervention: ASL Services (Behavioral)

Outcomes
Primary Outcomes
Change from Baseline in ASL Phonological Production Accuracy over 12 Months
Time Frame: Baseline and 12 months
Participants copy ASL signs produced on video; their productions are scored for phonological accuracy and reported as percent correct out of all possible phonological features. Weekly measures are taken for SCD analysis.
Secondary Outcomes
- Change from Baseline in ASL Production Frequency over 12 Months(Baseline and 12 months)
