Lesser Neural Pattern Similarity across Repeated Tests Is Associated with Better Long-Term Memory Retention.
UNLABELLED Encoding and retrieval processes enhance long-term memory performance. The efficiency of encoding processes has recently been linked to representational consistency: the reactivation of a representation that gets more specific each time an item is further studied. Here we examined the complementary hypothesis of whether the efficiency of retrieval processes also is linked to represen...
متن کاملMore is Better: The Effects of Multiple Repetitions on Implicit Memory Across Long Durations
Implicit memory was measured using word fragment completion up to 18 months after being exposed to words multiple times. In all cases participants showed significant priming for multiply presented words over singly presented ones. In shorter delay conditions (up to 6 weeks), implicit memory was tested using word reading speed and fragment completion. Both measures indicated larger effects follo...
متن کاملSpatiotemporal Neural Pattern Similarity Supports Episodic Memory
Formal computational models of human memory posit a central role of feature representations in episodic memory encoding and retrieval [1-4]. Correspondingly, fMRI studies have found that, in addition to activity level [5, 6], the neural activation pattern similarity across repetitions (i.e., self-similarity) was greater for subsequently remembered than forgotten items [7-9]. This self-similarit...
متن کاملWhy is greater medication adherence associated with better outcomes
BACKGROUND Previous studies found an association of greater adherence to placebo medication with better outcomes. The present study tested whether this association was explained by any of the following factors: 1) adherence to other medications, 2) healthcare behaviors, 3) disease risk, or 4) predicted degree of adherence. Data included information on more than 800 risk factors from 27,347 subj...
