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

But the left parietal ERP may reflect the outcome of high-level cortical processing during recollection. As goal-driven reconstruction can transform initial pattern-completed neural representations, we reasoned that goals and cues might impact recollection at multiple stages🧵4/9
