Clinical Trial Summary

This study examines the development of American Sign Language by deaf and hard of hearing (DHH) children and their parents.

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.
