Visual reinforcement audiometry

Visual reinforcement audiometry (VRA) is a key behavioural test for evaluating hearing in young children.[1][2] VRA is a good indicator of how responsive a child is to sound and speech and whether the child is developing awareness to sound as expected. VRA is typically used on children that are 6- 24 months. Using classic operant conditioning, a stimulus is presented, which is followed by a 90 degree head turn from midline by the child, resulting in the child being reinforced with an animation.[3] VRA works well until about 18-24 months of age. Above 18-24 months, children need more interesting tasks to hold their attention.
Conditioned orientation reflex (COR) is a variant of VRA where more than one sound is used.
