First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how people with schizophrenia organize memories of events. Participants took a 1-hour walk in Strasbourg while wearing an automatic camera. Later, they were asked to put photos from the walk in order and identify where events started and ended. The goal was to see if people with schizophrenia have trouble with the timing and structure of memories compared to healthy controls.
