Three-month-old infants were trained to move a mobile in the presence of a coconut or cherry odor (context). Six days later, a reactivation session took place. Infants were randomly assigned to 4 groups (same odor during training and reactivation, different odor during training and reactivation, no odor present during reactivation, no reactivation). A retention test was conducted 24h later in the presence of the training odor and mobile. Retention was seen only in the group of infants trained and reactivated with the same odor. This indicates that olfactory contextual cues function in a similar manner to visual and auditory contextual cues in that a novel context, or the absence of the context in which the memory was formed, are ineffective as reminders once the original memory has been forgotten.
三个月大的婴儿在椰子或樱桃气味（背景）存在的情况下被训练移动一个移动设备。六天后，进行了重新激活环节。婴儿被随机分配到 4 个组（在训练和重新激活时使用相同的气味，在训练和重新激活时使用不同的气味，在重新激活时没有气味，没有重新激活）。24 小时后，在训练气味和移动设备存在的情况下进行了保留测试。只有在接受相同气味的训练和重新激活的婴儿组中才观察到保留。这表明嗅觉背景线索的作用与视觉和听觉背景线索相似，即一旦原始记忆被遗忘，新的背景或形成记忆的背景不存在，作为提醒就无效了。
