三个实验测试了新生大鼠(7日龄、9日龄和12日龄)在非定向主动回避任务下，使用振动触觉条件刺激的学习和保持能力。假说是，这些动物在24小时保持能力上的巨大缺陷至少部分是由于记忆提取的缺陷。在实验一中，重新激活的治疗被发现在24小时内减轻了12天出生的婴儿的健忘，尽管对9天出生的动物的影响较小。再激活治疗对7日龄大鼠似乎无效。实验二和实验三证实了9天和12天婴儿再激活效应的可靠性，同时增加了进一步的控制条件，并提供了关于潜在抑制个体发生的新信息。
Three experiments tested the learning and retention of neonatal rats (7, 9, and 12 days of age) with a nondirectional active avoidance task, using a vibrotactile conditioned stimulus. The hypothesis was that the substantial deficit of these animals in 24-hr retention is due, at least in part, to a deficiency in memory retrieval. In Experiment I, a reactivation treatment was found to alleviate the forgetting over the 24-hr period for 12-day olds although having somewhat lesser effect for animals 9 days of age. The reactivation treatment seemed ineffective for rats 7 days of age. Experiments II and III confirmed the reliability of the reactivation effects with 9- and 12-day olds, while adding further control conditions and providing new information concerning the ontogenesis of latent inhibition.
