What is the primary purpose of Visual Reinforcement in Visual Reinforcement Audiometry (VRA) testing?

• A. To ensure the child remains still during testing.
• B. To encourage the child to respond by turning head toward sound by providing a reward.
• C. To calibrate the audiometer.
• D. To measure tympanic membrane mobility.

Answer: (B)

The main idea behind Visual Reinforcement Audiometry is to use a reward-based cue to elicit and reinforce a detectable response from the child. When a sound is played from a speaker, the child’s natural reaction is to turn toward the sound source, and immediately a visually appealing reward—like a lighted animation or toy on a screen—appears. This positive reinforcement strengthens the association between hearing the sound and making the head-turn response, making it more likely the child will respond again at softer levels. This operant-conditioning approach lets clinicians estimate hearing thresholds in preverbal or nonverbal children. The other options don’t fit this purpose: keeping the child still isn’t the primary goal, calibrating the audiometer is a technical task done with equipment, and measuring tympanic membrane mobility is a separate test (tympanometry) unrelated to how the child indicates detection in VRA.
