Adding the Missing Link to Language Assessment of Children with Hearing Loss: Language Environment Analysis
Researchers emphasize the importance of evaluation and intervention in a natural setting (e.g., Woods, 2008). However, analysis of truly naturalistic speech activity has traditionally required hours of laborious transcription of relatively short audio recordings. Because clinicians have been unable to obtain valid information about a child’s language environment and interaction outside the clinic, they are challenged to make decisions about effective treatment strategies in the absence of adequate data. Further, without a reliable way to assess a child’s natural language environment and behavior, clinicians and researchers have been unable to test the fidelity of various treatment approaches.
The LENA (Language Environmental Analysis) system, a novel way to assess young children’s language development/environment, addresses these challenges by taking advantage of recent advancements in hardware and software technology. The system comprises a two-ounce digital recorder that children wear; it records what they say and what is spoken around them continuously for 16 hours. The system generates a variety of output reports, including estimates of: 1) the number of adult words spoken near the child, 2) the number of turn-taking interactions the child engages in with an adult, and 3) the number of vocalizations produced by the child.
After assurance that the technology is providing the auditory access necessary for processing all of the sounds of the spoken English, it is important to determine whether the child is receiving sufficient auditory stimulation. Access to an assessment tool that is capable of automatically analyzing a child’s language environment is a potentially revolutionary development. Data from children with hearing loss using the LENA system with children who are deaf or hard of hearing will be presented. The research and clinical potential and limitations for use with children who have hearing loss will also be discussed.
- Participants will be able to identify why assessment of the language environment is critical for children with hearing loss. Participants will be able to identify the information provided by the LENA system. Participants will be able to describe how they can use LENA analysis in the development of intervention strategies.
