Learning from prediction errors
When memories are being used to predict what is going to happen next, they can be changed in the process. In three first studies, we have shown that the size of the prediction error is a crucial parameter in this process: When prediction errors are small, so when the prediction based on a memory matches the emerging reality, little memory change happens. When prediction errors are large, the old memory stays intact, but a new and separate memory is also encoded. When prediction errors are medium, however, the old memory is changed and adapted, and gets updated with new information. In further studies, we are investigating whether different types of prediction errors have different impacts, and if prediction errors based on a mismatch with our world knowledge are processed differently.
The aftermath of future thinking
Researchers have extensively investigated how participants imagine their own future. However, few studies have looked at how these predictions can shape the actual events, and how they are remembered. We therefore conducted three longitudinal studies surrounding national elections and asked participants to imagine the outcomes before the election, and to remember it afterwards. We were interested in whether larger prediction errors, even on such a different time scale and after explicit predictions, would lead to better memory for the event.
Sonyashnyk
The full-scale Russian invasion of Ukraine has strongly transformed the lives of Ukrainians, but also shook up the realities of people living in Central Europe. In a large-scale questionnaire study, we surveyed participants from Ukraine, Poland, and Germany. We investigated the effects of the invasion on traumatic memories, ways how people look to their future, and how people remember first hearing about the invasion (Flashbulb Memories).
