0061 Background Context but not Sleep Facilitates Visual Episodic Memory for Objects

Abstract Introduction Context serves as a retrieval aid and supports accurate recollection of elements within an episodic event. Associative links between the episode can be weakened via decontextualization. Memory traces are considered to decontextualized when they have undergone process that makes them less context-dependent more gist-like. Furthermore, sleep has been shown facilitate consolidation newly formed verbal memories, particularly occurs shortly after learning. The current study sought better understand what visual memories whether modulated by sleep. We examined changes in memory accuracy following either daytime nap or equivalent period quiet wakefulness background context was changed reinstated at retrieval. Methods Participants were presented with target objects appeared same scene across multiple trials changing scenes during encoding. for tested using two-alternative-forced-choice task before 90-min (or wakefulness). During testing, targets new scene. Results Preliminary behavioural results suggest recognition significantly decreased from Test 1 2. However, there no difference scores compared quite wakefulness. Recognition highest, both tests, encoding reinstated. There continually one change test. Conclusion When it comes memory, plays predominant role present reinforcing object consistent reinstatement facilitates strengthened object-to-scene binding, improving accuracy. This effect remains robust regardless learning followed wakefulness, suggesting rather than key Support (if any)
