Aberrant uncertainty processing is linked to psychotic-like experiences, autistic traits, and is reflected in pupil dilation during probabilistic learning
Kreis, Isabel; Zhang, Lei; Mittner, Matthias Bodo; Syla, Leonard Parks; Lamm, Claus; Gerit, Pfuhl (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-28)Aberrant belief updating due to misestimation of uncertainty and an increased perception of the world as volatile (i.e., unstable) has been found in autism and psychotic disorders. Pupil dilation tracks events that warrant belief updating, likely refecting the adjustment of neural gain. However, whether subclinical autistic or psychotic symptoms afect this adjustment and how they relate to learning ... -

Spared performance but increased uncertainty in schizophrenia: Evidence from a probabilistic decision-making task
Kreis, Isabel Viola; Zhang, Lei; Moritz, Steffen; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)Aberrant attribution of salience to in fact little informative events might explain the emergence of positive symptoms in schizophrenia and has been linked to belief uncertainty. Uncertainty is thought to be encoded by neuromodulators, including norepinephrine. However, norepinephrinergic encoding of uncertainty, measured as task-related pupil dilation, has rarely been explored in schizophrenia. ...
