Past meets present – Prediction error drives episodic memory updating
Great video about
- strengthening memories vs updating memories (with false details)
- interrupted videos -> prediction error -> signal to update
Neurons increased their response to an unexpected decrease in incoming sensory signal.
Comparison of perceptual input relative to expectations.
Design:
Encoding -> 24h -> Reactivation -> Recall
where in the Reactivation phase we have 2 groups: full videos and interrupted videos
24h to let the protein synthesis -> reconsolidate the memories.
But this is even more intersting:
Prediction errors drive memory updating Learning by switching between internally- vs. externally-biased modes of processing
