The benefit of being wrong: How prediction error size guides the reshaping of episodic memories

Episodic memories are not static – they shift and reshape as our surroundings evolve. One powerful mechanism for change are prediction errors, which a…

It was great to present my poster on distinct encoding after large predictions errors at ICON last week. Thanks to all who passed by to have a chat (i.e., shouting at each other at the top of one‘s lungs).

A huge thanks to my co-authors (including @nliedtke.bsky.social, @ssiestrup.bsky.social, @moritzwurm.bsky.social, @schubotzlab.bsky.social) for their substantial contributions to this work.

4) Both prior precision (how strong the prediction is) and prior accuracy (how good the prediction is) uniquely contribute to these processes with different time profiles.

3) These effects are implemented by reinstatement of the original episode (used for prediction) during the new and mismatching input. The more reinstatement, the more distinct encoding.

1) Larger PEs promote detailed memories that are more neurally distinct from the memories that were used for the prediction.
2) Medium PEs lead to less distinct memories, negatively impacting recognition performance.

New Paper Out!

Why do some prediction errors (PEs) lead to changes in episodic memories and others do not?

Our new research supports the idea that the size of the episodic PE plays a crucial role in shaping mnemonic and neural outcomes.

These are the 4 most important results:

Looks really nice and seems very useful especially now that quite a few students think it's not worth bothering learning a programming language if ChatGPT can do it (and then end up not being able to trouble-shoot anything). Thanks for putting this together!

Presenting our work on future thinking and remembering around elections today at @sarmac2025.bsky.social - Session 7, 11:40 (my talk starts around 12:10) in Moore Abbey. Pass by if you’re around! @studentssarmac.bsky.social

It was great to present this work for the first time - and looking forward to doing this again at @officialsarmac.bsky.social in Ireland next week!

He also gave an oral presentation on how event outcomes influence the relationship between future thinking and remembering. Participants changed their assessment of how important elections were depending on whether the elections went their way or not - showing strong self-serving biases.

Marius @mariusboeltzig.bsky.social presented his poster on the influence of prediction error size on memory - showing that large prediction errors lead to distinct encoding of new episodes, while keeping old ones intact.

Ah, we'll dig trenches around Berlin in two years because a guy who suggested drinking disinfectant thinks we're not thankful? Cool cool, let me just sharpen the discussion of whether my results are in congruence of the Latent Cause Theory.

We are looking for German or Ukrainian people participants for a 20-40 minutes survey. Topics are Flashbulb Memories, Negative Memories, and Future Thinking - and there are vouchers to be won.
