Episodic memory is a reconstructive process : during an event, the features composing it are encoded and stored separately in the brain, then reconstructed when the event's memory is retrieved. Even with source monitoring processes (e.g., did I see or did I smell it?), some mistakes can occur. These mnemonic mistakes happen especially when different events share several features, producing overlaps difficult to discriminate, leading to the creation of false memories. The common cuttlefish has the ability to remember specific events about what happened where and when, namely episodic-like memory. In order to investigate whether this memory, such as human episodic memory, is based on reconstructive processes, we elaborated a protocol promoting false memory formation. Our results suggest that cuttlefish do form visual false memories, but not olfactory false memories. These memory errors might be the first indication of the presence of reconstructive processes in the memory of cephalopods.
在一个事件发生期间，构成该事件的特征被分别编码并存储在大脑中，然后在检索该事件的记忆时进行重构。即使有来源监测过程（例如，我是看到了还是闻到了？），也可能会出现一些错误。这些记忆错误尤其会在不同事件共享多个特征时发生，产生难以区分的重叠，从而导致错误记忆的形成。普通乌贼有能力记住关于在何时何地发生了什么的特定事件，即类似情景记忆。为了研究这种记忆是否像人类情景记忆一样基于重构过程，我们制定了一个促进错误记忆形成的方案。我们的结果表明，乌贼确实会形成视觉错误记忆，但不会形成嗅觉错误记忆。这些记忆错误可能是头足类动物记忆中存在重构过程的首个迹象。
