简要总结
This study examines the development of American Sign Language by deaf and hard of hearing (DHH) children and their parents.
详细描述
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.
