When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was.

Why are some people more prone to believe in conspiracy theories? Part of the answer may lie in metacognition, i.e., the ability to correctly estimate one's own knowledge about topics.

Perhaps we need tasks other than beads to assess belief formation and updating?
With machine learning, this study showed that predictors from 51 theoretical models of delusions explain only 31% of the variance in persecutory beliefs, raising questions about current theories and pointing to gaps in understanding the specific aetiology of delusions.

🚨We believe this is a major step forward in how we study hippocampus function in healthy humans.
Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.
