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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline and 12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from Baseline in ASL Production Frequency over 12 Months
Time Frame: Baseline and 12 months
Participants engage in naturalistic play sessions which are videorecorded. Sessions are analyzed for the number of productions in ASL over a 15-minute period. Weekly measures are taken for SCD analysis.
Baseline and 12 months
