I am beyond proud that we have got so far with this project, combining science, education, and the mission to promote Ukraine's integration into European science. So much more to come - stay tuned! @linniplidot.bsky.social @clarerathbone.bsky.social @scottcolepsych.bsky.social

We are a group of eleven scientists in seven countries researching how Ukrainians remember and think about the future during the invasion. We have conducted a large-scale study in Ukraine, Poland, and Germany, are preparing several publications with this data, and are running education initiatives.

The SPOHAD LAB has a homepage! www.spohadlab.com The next step on a two-year journey that started as a crazy study idea and slowly transformed into a full-fledged international collaboration - the Spohad Lab now has its own homepage.

Great experience to work with computational neuroscientists and see how modelling and experiments can support each other.

Large prediction errors led to pattern-separated encoding, supporting our previous behavioural and fMRI results. Interestingly, the model does not require an explicit decision maker, but can rely on internal network dynamics, based on representational similarity.

These are the main findings of our new preprint, which is the first paper from the Spohad Lab we founded two years ago. Researchers from seven different countries, including Ukraine, working on memory and future thinking in Ukraine. @clarerathbone.bsky.social @scottcolepsych.bsky.social

NEW PREPRINT Ukrainians are more positive about their collective future than Germans and Poles. They also see their personal future as more intertwined with their country's and feel more agency to be able to change their country's future.

The Memory Lab congratulates @mariusboeltzig.bsky.social to the successful defense of his PhD! Well done Dr. Boeltzig! 👨‍🎓 Marius did excellent research in the @schubotzlab.bsky.social on understanding how the size of prediction errors shapes episodic memory. 🧠 Make sure to check out his work!

After 3.5 years, I defended my PhD in Psychology, with my thesis "Learning From The Unexpected: How Prediction Error Size Shapes Episodic Memory". So grateful to colleagues, collaborators, and friends who were part of this journey!

I taught this in Germany, and even within a leftist student crowd who all biked to the seminar, the need to own a car for a happy life was taken as self-evident (you just don’t get the same speed when you take your goat on the Autobahn).

Marius Boeltzig @mariusboeltzig.bsky.social · 02/04/2026

Exactly three weeks before my PhD defense, the third and last paper of the thesis was published! We tested the neural correlates and representational and behavioural consequences of updating vs separating events after prediction errors. doi.org/10.1016/j.ne...

They also misremember what they had predicted before the election: If they now think the election was fair (because they won it), they overestimate the assessment of election fairness they had made before the election.

Marius Boeltzig @mariusboeltzig.bsky.social · 18/03/2026

Across three 2024 elections, we found that voters shift assessments during future thinking and remembering depending on election success: For instance, they increase their perception of importance and fairness if their party wins the election.

Such an amazingly active group, with so much curiosity and knowledge. It is so impressive that despite massive power and heating outages in Kyiv, so many people turn up to discuss memory. An inspiring reminder of how great science and learning are. Grateful to do this with @linniplidot.bsky.social

Day 1 focused on the cog-neuroscience of memory, with great talks by Mikael Johansson and Inês Bramão from @lund-memory-lab.bsky.social, followed today by great lectures on mental time travel (also in patients) by @scottcolepsych.bsky.social and on (in)voluntary retrieval by Krystian Barzykowski.

Just kicked off the Kyiv Winter School of Memory 2026 with over 70 participants of different universities in Ukraine. So rewarding to see this slightly crazy idea become a reality. Thanks to @linniplidot.bsky.social and Karine Malysheva (National University of Kyiv) for organising this with me.

So now, it is time to find out why. Thanks to @officialsarmac.bsky.social and especially the Diversity and Inclusion Committee for their assessment and making this study possible.

Marius Boeltzig @mariusboeltzig.bsky.social · 06/01/2026

This will allow us to collect follow-up data on personal and collective future thinking in Ukraine, this time also including a sample of LGBTQ+ people. In a previous study (in preparation), we found that Ukrainians were MORE positive about their collective future than Germans and Poles!

I think part of it is that the philosophy "hits over time" is still very strong in Germany. Both her and Strelow seemed to prefer not to shoot if they cannot be sure that they will hit. Under most conditions, this leads to excellent hit rates - and now to two dreadfully slow range times...

We're now a team of 12 people in 8 countries, and preparing papers on future thinking (a bit of anticipatory clickbait: the results are genuinely stunning), Flashbulb Memories, and traumatic memories. More data collections are to come. Watch this space - and help Ukrainian defenders.

Marius Boeltzig @mariusboeltzig.bsky.social · 11/10/2025

In a seminar, I had the chance to report how I started the collaboration with Ukrainian colleagues and how we collected data there. Weirdly, that story started in the russian city of Perm in 2013 - and the project somehow feels like the culmination of much of my adult life.

Marius Boeltzig @mariusboeltzig.bsky.social · 11/10/2025

Once again, my admiration for Ukraine grew even more. It is inspiring to see how our colleagues have adapted to the situation and simply keep on doing their work - and how motivated they are to even make use of the situation to change the country and achieve stronger alignment with Europe.

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.

110

Marius Boeltzig @mariusboeltzig.bsky.social · 21/07/2025

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.

110

Marius Boeltzig @mariusboeltzig.bsky.social · 21/07/2025

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.

Marius Boeltzig @mariusboeltzig.bsky.social · 21/07/2025

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:
