Valence-Dependent Belief Updating: Computational Validation [PDF]
Frontiers in Psychology, 2017 People tend to update beliefs about their future outcomes in a valence-dependent way: they are likely to incorporate good news and to neglect bad news. However, belief formation is a complex process which depends not only on motivational factors such as ...

Paranoia as a deficit in non-social belief updating [PDF]
eLife, 2020 Paranoia is the belief that harm is intended by others. It may arise from selective pressures to infer and avoid social threats, particularly in ambiguous or changing circumstances.

Frequency-specific changes in prefrontal activity associated with maladaptive belief updating in volatile environments in euthymic bipolar disorder [PDF]
Translational PsychiatryBipolar disorder (BD) involves altered reward processing and decision-making, with inconsistencies across studies. Here, we integrated hierarchical Bayesian modelling with magnetoencephalography (MEG) to characterise maladaptive belief updating in this ...

Individual differences in belief updating and phasic arousal are related to psychosis proneness [PDF]
Communications PsychologyMany decisions entail the updating of beliefs about the state of the environment by accumulating noisy sensory evidence. This form of probabilistic reasoning may go awry in psychosis.

Models of Dynamic Belief Updating in Psychosis—A Review Across Different Computational Approaches [PDF]
Frontiers in Psychiatry, 2022 To understand the dysfunctional mechanisms underlying maladaptive reasoning of psychosis, computational models of decision making have widely been applied over the past decade.

Impaired belief updating and devaluation in adult women with bulimia nervosa [PDF]
Translational Psychiatry, 2023 Recent models of bulimia nervosa (BN) propose that binge-purge episodes ultimately become automatic in response to cues and insensitive to negative outcomes.

Belief updating in bipolar disorder predicts time of recurrence [PDF]
eLife, 2020 Bipolar disorder is a chronic relapsing condition in which mood episodes are interspersed with periods of wellbeing (euthymia). Shorter periods of euthymia are associated with poorer functioning, so it is crucial to identify predictors of relapse to ...

Biased belief updating and suboptimal choice in foraging decisions [PDF]
Nature Communications, 2020 In some types of decision-making, people must accept or forego an option without knowing what prospects might later be available. Here, the authors reveal how a key bias– asymmetric learning from negative versus positive outcomes – emerges in this type ...

A General Framework for Updating Belief Distributions [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2015 We propose a framework for general Bayesian inference. We argue that a valid update of a prior belief distribution to a posterior can be made for parameters which are connected to observations through a loss function rather than the traditional ...

Pupil diameter encodes the idiosyncratic, cognitive complexity of belief updating [PDF]
eLife, 2020 Pupils tend to dilate in response to surprising events, but it is not known whether these responses are primarily stimulus driven or instead reflect a more nuanced relationship between pupil-linked arousal systems and cognitive expectations.
