The purpose of this investigation was to study the relationship between visual reinforcement audiometry (VRA) performance and age (i.e., corrected and mental) with 60 premature infants. VRA performance was classified as unacceptable, marginal, or acceptable based on conditionability and number of responses obtained before habituation to the task. The results indicated that mental age and corrected age were significantly related to VRA performance. It was found that a corrected age of 8 mo and/or a mental age of 6 mo is typically required for acceptable performance using VRA. A lack of responsiveness to the VRA procedure at these ages would most likely be due to hearing loss as opposed to a general developmental delay. The data from this study would not support a large scale behavioral hearing screening program for premature infants below 8 mo corrected age or 6 mo mental age.
本研究的目的是研究60名早产儿的视觉强化听力测验（VRA）表现与年龄（即矫正年龄和心理年龄）之间的关系。根据对任务的可调节性和习惯化之前获得的反应数量，VRA表现被分为不可接受、边缘或可接受。结果表明，心理年龄和矫正年龄与VRA表现显著相关。研究发现，使用VRA获得可接受表现通常需要8个月的矫正年龄和/或6个月的心理年龄。在这些年龄对VRA程序缺乏反应最可能是由于听力损失，而不是一般的发育迟缓。本研究的数据不支持对矫正年龄低于8个月或心理年龄低于6个月的早产儿进行大规模行为听力筛查项目。
