Translating Research to Practice in Sign Language Acquisition (PD102640)

Presenter(s): Stephanie DeAnda, PhD, CCC-SLP; Matthew Hall, PhD; Naomi Caselli, PhD
Course Description

This session highlights recent advances in understanding language acquisition in children who are deaf/hard of hearing (DHH), with an emphasis on the acquisition of sign languages (either on their own or alongside spoken languages). Conceptual advances include: (1) a more accurate way of thinking about “average range” when interpreting research data and (2) the development of “language access profiles” as an alternative to “communication mode.” Speakers present advances in measurement, by introducing three new tools that are available for clinical use: the D-LEAT, the LAPT, and the ASL-CDI 2.0. The session concludes by highlighting recent empirical discoveries about the relationship between the timing of American Sign Language (ASL) access, the amount of ASL input, and the trajectory of ASL vocabulary acquisition in DHH children from hearing families.

This course is a recorded session from the 2021 ASHA Convention Virtual Library (session 2225V). It was developed by, and presenters were invited by, Listening, Language and Speech in Children Who are Deaf and Hard of Hearing.

Content disclosure: This session covers a broad spectrum of recent research results about early language experiences and language acquisition in young deaf/hard of hearing children, including descriptions of three tools for measuring language experience and language background: D-LEAT, LAPT, and ASL-CDI 2.0.

Learning Outcomes
You will be able to:

  • Identify conceptual problems that have been barriers to understanding language acquisition in DHH children
  • Describe new tools that clinicians can use to address those limitations
  • Summarize the findings of recent studies that have used those tools
