Studies of fast mapping (FM) in adults have included both positive results and failures to replicate. I argue that although conflicting studies warrant caution, FM findings are nonetheless promising and intriguing. I separate the issue into distinct questions: whether FM has hippocampal independence, and whether it has unique cognitive consequences. I clarify some misunderstandings and identify limitations that may contribute to failures to find learning from FM in some amnesic patients. Finally, I argue that the array of behavioral findings in healthy adults is consistent with computational and neural models.
成人快速映射(FM)的研究包括积极的结果和未能复制的结果。我认为,尽管相互矛盾的研究需要谨慎对待,但 FM 的发现仍然是有希望和有趣的。我将这个问题分为两个不同的问题:FM 是否具有海马独立性,以及它是否具有独特的认知后果。我澄清了一些误解,并确定了可能导致在某些遗忘症患者中无法从 FM 中发现学习的局限性。最后,我认为健康成年人的一系列行为发现与计算和神经模型是一致的。
