我们评估了暴露于双峰刺激（如节奏，速率，持续时间）中的非模态特性是否可以在产前发育期间教育注意随后的单峰刺激中的非模态特性。在孵化前一天，在几种实验和对照条件下，将Bobwhite鹌鹑胚胎暴露于单个Bobwhite母体呼叫。实验组接受对单个母亲呼叫的时间特征的冗余听觉和视觉暴露，然后立即或在2小时或4小时延迟后对同一呼叫进行单峰听觉暴露。对照组接受（1）相同的暴露，但顺序相反（单模态→冗余双模态），（2）异步双模态→单模态，（3）仅单模态暴露，或（4）仅双模态暴露。所有的实验组显示出显着的偏好，熟悉的母亲的电话超过一个新的母亲的电话时，测试2天后孵化，而没有一个控制组显示出显着的偏好，熟悉的电话。这些结果表明，感觉间冗余可以将注意力引导到双峰刺激中的非模态特性，并在随后的没有感觉间冗余的单模态刺激中教育人们注意相同的非模态特性。
We assessed whether exposure to amodal properties in bimodal stimulation (e.g. rhythm, rate, duration) could educate attention to amodal properties in subsequent unimodal stimulation during prenatal development. Bobwhite quail embryos were exposed to an individual bobwhite maternal call under several experimental and control conditions during the day prior to hatching. Experimental groups received redundant auditory and visual exposure to the temporal features of an individual maternal call followed by unimodal auditory exposure to the same call immediately or after a 2‐hr or 4‐hr delay. Control groups received (1) the same exposure but in the reverse sequence (unimodal → redundant bimodal), (2) asynchronous bimodal → unimodal, (3) only unimodal exposure, or (4) only bimodal exposure. All experimental groups showed a significant preference for the familiar maternal call over a novel maternal call when tested 2 days after hatching, whereas none of the control groups showed a significant preference for the familiar call. These results indicate that intersensory redundancy can direct attention to amodal properties in bimodal stimulation and educate attention to the same amodal properties in subsequent unimodal stimulation where no intersensory redundancy is available.
