Neural mechanisms of reactivation-induced updating that enhance and distort memory.
We remember a considerable number of personal experiences because we are frequently reminded of them, a process known as memory reactivation. Although memory reactivation helps to stabilize and update memories, reactivation may also introduce distortions if novel information becomes incorporated with memory. Here we used functional magnetic resonance imaging (fMRI) to investigate the neural mec...
متن کاملNeural reactivation reveals mechanisms for updating memory.
Our ability to remember new information is often compromised by competition from prior learning, leading to many instances of forgetting. One of the challenges in studying why these lapses occur and how they can be prevented is that it is methodologically difficult to "see" competition between memories as it occurs. Here, we used multi-voxel pattern analysis of human fMRI data to measure the ne...
متن کاملHow reactivation strength affects memory updating
Memory reactivation induces plasticity, rendering reactivated memories susceptible to interference. The current study examined whether the method and strength of reactivation modulates retroactive interference effects. Two days after learning AB word pairs, memory for these pairs was either not reactivated, moderately reactivated (presentation of A cues in an unrelated task), or strongly reacti...
متن کاملDissociable neural mechanisms for goal-directed versus incidental memory reactivation.
Remembering a past event involves reactivation of distributed patterns of neural activity that represent the features of that event-a process that depends on associative mechanisms supported by medial temporal lobe structures. Although efficient use of memory requires prioritizing those features of a memory that are relevant to current behavioral goals (target features) over features that may b...
متن کاملThe Effect of Trait Anxiety and Induced Anxiety on the Updating of Working Memory Function
Background & Aims:The aim of the present study was to use a psychological model to explain the effect of trait anxiety and induced anxiety on individual’s performance in updating function of working memory. This study was also designed to test attentional control theory of Eysenck et al. Methods: Throngh Multistage Cluster sampling method, 330 freshman un...
