Application of visual reinforcement audiometry (VRA) to low-functioning children.
Visual reinforcement audiometry (VRA) was studied on a group of low-functioning children in an ongoing clinical program. After establishing the specific reinforcing value of the visual stimulus, threshold assessments were made. VRA was an effective test procedure for most of the children tested, providing their developmental ages reached approximately the 10-month level or higher. On the basis of VRA thresholds and tympanometry, 52% of the children seen were referred for medical evaluation. A variation of VRA was used to assess syllable-discrimination performance on a pilot basis. Results are discussed in terms of the potential use of VRA to assess infant spedch-sound discrimination in addition to its current use as an indicator of hearing sensitivity.
