Re-exposure to elements of prior experiences can create opportunities for inducing amnesia for those events. The dominant theoretical framework posits that such re-exposure can result in memory destabilization, making the memory representation temporarily sensitive to disruption while it awaits reconsolidation. If true, such a mechanism that allows for memories to be permanently changed could have important implications for the treatment of several forms of psychopathology. However, there have been contradictory findings and elusive occurrences of replication failures within the "reconsolidation" field. Considering its potential relevance for clinical applications, the fact that this "hot" research area is being dominated by a single mechanistic theory, and the presence of unexplainable contradictory findings, we believe that it is both useful and timely to critically evaluate the reconsolidation framework. We discuss potential issues that may arise from how reconsolidation interference has typically been deducted from behavioral observations, and provide a principled assessment of reconsolidation theory that illustrates that the theory and its proposed boundary conditions are vaguely defined, which has made it close to impossible to refute reconsolidation theory. We advocate for caution, encouraging researchers not to blindly assume that a reconsolidation process must underlie their findings, and pointing out the risks of doing so. Finally, we suggest concrete theoretical and methodological advances that can promote a fruitful translation of reminder-dependent amnesia into clinical treatment.
重新接触先前经历的元素可以为那些事件的遗忘创造机会。主导的理论框架假设,这种重新接触可能导致记忆失稳,使记忆表现暂时容易受到干扰,同时等待重新巩固。如果这是真的,这种允许记忆永久改变的机制可能对治疗几种形式的精神病理学有重要意义。然而,在“再巩固”领域内,存在着相互矛盾的发现和难以复制的失败。考虑到其对临床应用的潜在相关性,以及这个“热门”研究领域被单一的机械论理论所主导,以及存在无法解释的相互矛盾的发现,我们认为批判性地评估再巩固框架既有用又及时。我们讨论了可能出现的问题,这些问题可能源于如何从行为观察中推断出再巩固干扰,并且对再巩固理论进行了原则性评估,该评估表明该理论及其提出的边界条件定义模糊,这使得几乎不可能反驳再巩固理论。我们提倡谨慎,鼓励研究人员不要盲目假设再巩固过程必须是他们发现的基础,并指出这样做的风险。最后,我们提出了具体的理论和方法上的进展,可以促进基于记忆提醒的遗忘向临床治疗的有效转化。
