The role of localization in visual reinforcement audiometry.

The response task employed in visual reinforcement audiometry (VRA) has been characterized both as a localization response and, alternatively, as a pure operant conditioning behavior independent of localization. This study examined the role of localization in VRA conditioning and threshold procedures by varying the localization information provided to normal infants. Results indicate (a) that the VRA response is not contingent on localization but (b) that performance may be significantly influenced by localization. The findings suggest that any variable that alters proper localization cues, including equipment arrangement or impaired auditory function, may degrade response performance.
