摘 要: 
  The ability to control unwanted memories is critical for maintaining cognitive function and mental health. Prior researchhas shown that suppressing the retrieval of unwanted memories impairs their retention, as measured using intentional(direct) memory tests. Here, we review emerging evidence revealing that retrieval suppression can also reduce theunintended influence of suppressed traces. In particular, retrieval suppression (a) gradually diminishes the tendencyfor memories to intrude into awareness and (b) reduces memories’ unintended expressions on indirect memory tests.We present a neural account in which, during suppression, retrieval cues elicit hippocampally triggered neocorticalactivity that briefly reinstates features of the original event, which, in turn, are suppressed by targeted neocortical andhippocampal inhibition. This reactivation-dependent reinstatement principle could provide a broad mechanism bywhich suppressing retrieval of intrusive memories limits their indirect influences.
