(7) Huge thanks 🖤 to Verena, @Lucy_MacG & @chmathys for the amazing collaboration. Can't wait to share more from this project soon!

(6) We could also demonstrate that this change was specific to schizotypy as neither autistic traits nor verbal comprehension proficiency led to a significant shift in the prior weight.

(5) Study 2 (n=55) confirmed this finding and revealed that overweighting prior beliefs was associated with increased levels of cingulate glutamate, pointing to a neurobiological basis for this bias toward top-down expectations.

(4) Study 1 (n=109) found that higher schizotypy was linked to greater reliance on prior beliefs over sensory evidence - a pattern suggesting an overweighting of prior beliefs in people at higher risk for psychosis which also manifested in a higher frequency of false percepts.

(3) In our predictive language task, we manipulated sentence predictability, sensory clarity, and surprise. Using a Bayesian belief updating model, we estimated the “prior weights” in how individuals integrated their expectations vs. the sensory data.

(2) We explored how people with schizotypal traits (a subclinical form of psychosis-proneness) rely on high-level priors vs. incoming sensory evidence to decipher noisy speech inputs.

(1) Predictive coding models suggest that psychotic symptoms like hallucinations & delusions might stem from an imbalance between the weighting of prior beliefs and sensory evidence.

Super excited to share our new preprint, led by my supervisor Franziska Knolle in collaboration with Verena Demler, @Lucy_MacG & @chmathys: 💡Guided by Expectations: Overweighted Semantic Priors in Schizotypy and their Links to Glutamate https://t.co/ffxyc4B9DP A thread 🧵:

Visiting #PuG2024 and interested in perception under uncertainty? Then join our symposium on Thursday May 30th 10.30 o'clock and my talk about oscillatory signatures of predictions in social and sensory perception! We are looking forward to see many of you there 🧠

Excited to share my new preprint with Paul Sauseng and @Artipago! 🥳By investigating the propagation direction of alpha waves, we distinguished between bottom-up and top-down inhibitory processes during working memory. For more details: https://t.co/F3inxx9at8

Here comes a Valentine's Day Present 💝 Check out our brand new pre-Print: "Oscillatory brain activity as unified control mechanism for working memory and mentalizing" https://t.co/YvajtHZb45 by @ElisabethVCF @HillaYannik @ESterner_ Simon Ostermeier @BehnkeLara & @PSauseng

It has long been thought that coordination of briefly maintained information (so-called working memory) and higher social cognition (mentalizing) rely on mutually exclusive brain mechanisms. However,...

We have news on the Bayesian 👻 ! Brilliant Charline Peylo @ESterner_
@YifZen and @ElisabethVCF provide evidence in favor of the Bayesian 👻 being casually linked to the premotor cortex 🧠 using TMS. Check out their pre-registered report on biorxiv!🥳 https://t.co/taK6OmvogE
