Unlike the other sensory modalities of precocial infants, the visual modality does not normally become functional until after birth or hatching. Despite this unique developmental status, the role of emerging visual experience on postnatal perceptual organization remains unclear. In this study, bobwhite quail hatchlings were reared in conditions that manipulated postnatal experience with maternal visual cues, either alone or in conjunction with maternal auditory cues. Results revealed that bobwhite chicks require postnatal exposure to both maternal auditory and visual cues following hatching to demonstrate species-specific perceptual preferences. Chicks that received temporally disparate maternal auditory and visual cues or experience with only maternal visual or maternal auditory cues failed to show species-typical perceptual responsiveness. These results suggest that developmental mechanisms involving both visual and auditory sensory experience underlie the emergence of early intersensory integration.
与早成雏鸟类的其他感觉模态不同，视觉模态通常在出生或孵化后才开始发挥功能。尽管具有这种独特的发育状态，但出生后新兴视觉经验对产后知觉组织的作用仍不清楚。在本研究中，将刚孵出的北美鹑置于这样的条件下饲养：单独或与母体听觉线索一起操纵其产后对母体视觉线索的经验。结果显示，北美鹑雏鸟在孵化后需要同时接触母体听觉和视觉线索，才能表现出物种特异性的知觉偏好。那些接受了时间上不同的母体听觉和视觉线索，或者只经历了母体视觉或母体听觉线索的雏鸟，未能表现出物种典型的知觉反应。这些结果表明，涉及视觉和听觉感官经验的发育机制是早期跨感觉通道整合出现的基础。
