Hi! Nice to virtually meet you! Here is the QR code to a PDF of the poster. Glad you found it interesting! If you have any questions or want more details, happy to chat about it! 🙂

Results suggest at least two stages of selection within the retrieval cascade: 1) external cues modify which memories get reinstated & 2) further goal-driven processing amplifies targeted memories in line with goals. For simple model inspired by doi.org/10.1016/j.ti... 🧵8/9

Final result: people also reinstated neural patterns as they prepared to retrieve the upcoming trial (at least when cues were words). As predicted by the encoding specificity principle this preparatory goal-related reinstatement may be how selective retrieval is achieved🧵7/9

This differed with our original findings for the left parietal ERP. This ERP (Bottom Left) was more target-selective than reinstatement (Top Left) when cues matched targets more, but when cues matched non-targets more, only reinstatement was selective for non-targets (Right for comparison)🧵6/9

Decoding of scalp ERPs showed: reinstatement of study phase neural patterns was target-selective when the external cues matched targets = audio with word cues (Exp1) or pictures with picture cues (Exp2), but was reversed (non-target > target) when cue match was greater with non-targets🧵5/9

In earlier study, people had to retrieve target objects studied as audios or pictures (in #CABN see doi.org/10.3758/s134...). Retrieval success ERPs (left parietal effect) were target-selective (> non-targets) – but only when external cues matched the targeted information🧵3/9

How do people select relevant memories out of a large store of events? We measured🧠#EEG neural reinstatement to test how selective memory retrieval is achieved 🧵1/9

Follow the end of the rainbow and come and see my poster tomorrow at #EPSYork24 ✨🍀. We’ll chat about how we forget and I’ll show you some initial work w/ @aidanhorner.bsky.social 🧠🐘
