Memory reconsolidation theory posits that consolidated memories can undergo destabilization following reactivation, allowing changes in its content and/or strength. Prediction error (PE) is considered to be the driving force for learning in both consolidation and reconsolidation. Vast evidence supports both these accounts. In our day-to-day life, we learn from complex situations and stimuli which do not follow explicit rules and cannot be sufficiently described by simple associations. We designed a behavioral task to study memory updating using complex audiovisual stimuli in an online modality. The selected videos are plot- and character-driven to engage participants´ curiosity. We aim to evidence memory updating of richly detailed episodic memories following reactivation under two distinct conditions: one that generates a PE through sudden interruption of some videos and one that does not. On testing day, participants are asked to recall general information and specific details about target videos, allowing for detection of intrusions from interference videos watched following reactivation.
