15th ANNUAL EARLY HEARING DETECTION & INTERVENTION MEETING
March 13-15, 2016 • San Diego, CA

Sound Discrimination in Infants
Universal newborn hearing screening has paved the way for early identification and treatment of hearing loss. However, there is an additional factor that must be considered. At this point we are able to obtain reliable information about detection of sound in very young infants. Unfortunately, the ability to discriminate between sounds is typically not measured until a child reaches about age three. The ability to distinguish one sound from another is vitally important for development of speech and language. Information about auditory discrimination can also be used to ensure that hearing aids and cochlear implants are programmed `appropriately and may help guide aural habilitation efforts. Visual Reinforcement Infant Speech Discrimination (VRISD) is a clinical tool that is currently available for assessment of speech sound discrimination in infants and young toddlers. VRISD allows for assessment of a child’s ability to discriminate between single syllables using a method similar to Visual Reinforcement Audiometry (VRA). This is accomplished by use of an oddball paradigm, in which one repeating syllable (e.g. /a/) is occasionally replaced by a different syllable (e.g., /i/). The child is trained to turn his or her head when a change in stimulus is perceived and is rewarded with a light-up toy or video when a change is successfully detected. In infants with normal hearing, certain speech sound contrasts have been found to be consistently easier to distinguish than others. This continuum of difficulty will be analyzed and discussed. Discussion will focus on implications for intervention in infants with hearing loss. Finally, steps required for VRISD to become an efficient, reliable, and widely-used clinical protocol will be outlined.
- classify speech sounds according to difficulty of discrimination in normal hearing infants.
- define visual reinforcement infant speech discrimination (VRISD) and its clinical applicability.
