对动物胚胎和人类婴儿的研究提供了证据，证明在早期发育过程中，信息冗余和跨感觉模态的时间同步（感觉间冗余）可以指导选择性注意，知觉学习和记忆。这种促进作用是如何实现的，相对而言尚未得到研究。本研究探讨了冗余与非冗余双峰刺激对鹌鹑胚胎生理唤醒（心率）的影响。结果表明，鹌鹑胚胎暴露于并发的，但非冗余的听觉和视觉刺激在孵化的后期阶段表现出显着升高的心率刺激曝光后，并在刺激再曝光时相比，胚胎暴露于冗余和同步的视听刺激，单峰听觉刺激，或没有补充产前感官刺激。这些研究结果表明，冗余和非冗余双峰刺激在早期发展的功能区别，并建议，非冗余双峰刺激在产前期间可以提高唤醒水平，从而可能干扰注意力的能力和感知学习的北美鹌鹑。相比之下，感觉间冗余似乎促进唤醒水平，促进产前发育期间的选择性注意和知觉学习。© 2003威利期刊公司Dev Psychobiol 43：304-310，2003.
Research with both animal embryos and human infants has provided evidence that information presented redundantly and in temporal synchrony across sensory modalities (intersensory redundancy) can guide selective attention, perceptual learning, and memory during early development. How this facilitation is achieved remains relatively unexamined. This study examined the effects of redundant versus nonredundant bimodal stimulation on a measure of physiological arousal (heart rate) in bobwhite quail embryos. Results show that quail embryos exposed to concurrent but nonredundant auditory and visual stimulation during the late stages of incubation exhibit significantly elevated heart rates following stimulus exposure and during stimulus reexposure when compared to embryos exposed to redundant and synchronous audiovisual stimulation, unimodal auditory stimulation, or no supplemental prenatal sensory stimulation. These findings indicate a functional distinction between redundant and nonredundant bimodal stimulation during early development and suggest that nonredundant bimodal stimulation during the prenatal period can raise arousal levels, thereby potentially interfering with the attentional capacities and perceptual learning of bobwhite quail. In contrast, intersensory redundancy appears to foster arousal levels that facilitate selective attention and perceptual learning during prenatal development. © 2003 Wiley Periodicals, Inc.
