本研究探讨了双峰视听刺激和单峰视觉刺激对婴儿在5分钟、2周或1个月的保持间隔后对移动玩具锤子视觉方向记忆的影响。根据intersensory冗余假说检测和记忆nonredundantly指定的属性，包括事件的视觉方向，促进在单峰刺激和衰减双峰刺激在早期发展。然而，在以后的发展中，非冗余指定的属性可以在多模态和单模态刺激中被感知和记忆。目前的研究将这些预测的测试扩展到了3个月、5个月和9个月大的婴儿的记忆领域。与感觉冗余假说的预测一致，在单峰刺激中，视觉方向的记忆出现了5个月，并保持稳定的年龄，而在双峰刺激中，记忆直到9个月大才出现。即使在1个月的延迟后，对方向的记忆也很明显，并且表现为一种不断变化的偏好，从新奇到零再到熟悉，随着保持时间的增加，与Bahrick和同事的注意力四阶段模型一致。总之，这些研究结果表明，婴儿记忆的非冗余指定的属性的事件是一个结果，选择性注意这些事件的属性，并促进在单峰刺激。因此，非冗余指定的属性的记忆出现在单峰刺激，后来扩展到双峰刺激，并持续一段时间，至少1个月。
This research examined the effects of bimodal audiovisual and unimodal visual stimulation on infants’ memory for the visual orientation of a moving toy hammer following a 5-min, 2-week, or 1-month retention interval. According to the intersensory redundancy hypothesis detection of and memory for nonredundantly specified properties, including the visual orientation of an event, are facilitated in unimodal stimulation and attenuated in bimodal stimulation in early development. Later in development, however, nonredundantly specified properties can be perceived and remembered in both multimodal and unimodal stimulation. The current study extended tests of these predictions to the domain of memory in infants of 3, 5, and 9 months of age. Consistent with predictions of the intersensory redundancy hypothesis, in unimodal stimulation, memory for visual orientation emerged by 5 months and remained stable across age, whereas in bimodal stimulation, memory did not emerge until 9 months of age. Memory for orientation was evident even after a 1-month delay and was expressed as a shifting preference, from novelty to null to familiarity, across increasing retention time, consistent with Bahrick and colleagues’ four-phase model of attention. Together, these findings indicate that infant memory for nonredundantly specified properties of events is a consequence of selective attention to those event properties and is facilitated in unimodal stimulation. Memory for nonredundantly specified properties thus emerges in unimodal stimulation, is later extended to bimodal stimulation, and lasts across a period of at least 1 month.
