In contrast to the large body of work on young infants' capacity to perceive temporally based intersensory relations, little research has been done on the role of spatial contiguity in the development of audio-visual integration. This study examined the effects of early postnatal sensory experience on an avian neonate's responsiveness to the spatial contiguity between maternal auditory and visual cues. Specifically, we assessed whether a bobwhite quail chick's ability to respond to the correspondence between the location of auditory and visual events is affected by its sensory-stimulation history. Results revealed that chicks denied species-typical auditory or visual experience in the period immediately following hatching showed altered patterns of responsiveness to maternal auditory and visual cues. In particular, chicks that received modified postnatal sensory experience demonstrated a higher tolerance for audio-visual spatial discrepancy than did control chicks. These results provide evidence of the important role of sensory experience in the emergence of intersensory integration during the perinatal period and highlight the role of spatial information in early perceptual responsiveness to maternal cues.
与大量关于幼儿感知基于时间的跨感觉关系能力的研究相比，关于空间邻近性在视听整合发展中的作用的研究很少。本研究考察了出生后早期感觉经验对鸟类新生儿对母体听觉和视觉线索之间空间邻近性反应的影响。具体来说，我们评估了北美鹑雏鸡对听觉和视觉事件位置对应关系的反应能力是否受到其感觉刺激历史的影响。结果显示，在孵化后立即被剥夺典型物种听觉或视觉经验的雏鸡，对母体听觉和视觉线索的反应模式发生了改变。特别是，接受了改变后的出生后感觉经验的雏鸡，比对照雏鸡对视听空间差异表现出更高的耐受性。这些结果证明了感觉经验在围产期跨感觉整合出现中的重要作用，并突出了空间信息在对母体线索的早期感知反应中的作用。
