当我们想起一些我们宁愿不去想的事情时，我们通常会试图将不想要的记忆排除在意识之外。最近的研究表明，人们通过停止记忆提取来控制不想要的记忆，使用的机制类似于停止反射性运动反应的机制。控制不想要的记忆是由外侧前额叶皮质实现的，它的作用是减少海马体的活动，从而损害对这些记忆的保留。这些系统有效性的个体差异可能是人们在控制侵入性记忆和适应创伤后的不同程度上的基础。本研究支持主动遗忘过程的存在，并建立了探讨动机遗忘的神经认知模型。
When reminded of something we would prefer not to think about, we often try to exclude the unwanted memory from awareness. Recent research indicates that people control unwanted memories by stopping memory retrieval, using mechanisms similar to those used to stop reflexive motor responses. Controlling unwanted memories is implemented by the lateral prefrontal cortex, which acts to reduce activity in the hippocampus, thereby impairing retention of those memories. Individual differences in the efficacy of these systems may underlie variation in how well people control intrusive memories and adapt in the aftermath of trauma. This research supports the existence of an active forgetting process and establishes a neurocognitive model for inquiry into motivated forgetting.
