    A Bayesian model of context-sensitive value attribution

    Francesco Rigoli et al.
    The dependence of incentive value attribution on the anticipation of rewards within a given context is explained via a normative Bayesian account of how rewards map to incentive values.

    Neural arbitration between social and individual learning systems

    Andreea Oliviana Diaconescu et al.
    Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.

    Meta-Research: Dataset decay and the problem of sequential analyses on open datasets

    William Hedley Thompson et al.
    Open data provides an opportunity to perform new analyses on preexisting data, but trade-offs are required to limit an increase in false positives.

    Estimating SARS-CoV-2 seroprevalence and epidemiological parameters with uncertainty from serological surveys

    Daniel B Larremore et al.
    Integrating over multiple forms of statistical uncertainty associated with serological surveys can improve serosurvey design while also enabling that uncertainty to be appropriately propagated through epidemiological models.

    Impaired adaptation of learning to contingency volatility in internalizing psychopathology

    Christopher Gagne et al.
    Hierarchical modeling of internalizing symptoms and task performance reveals that difficulty adapting probabilistic learning to second-order uncertainty is common to anxiety and depression and holds across rewarding and punishing outcomes.
    1. Neuroscience

    Paranoia as a deficit in non-social belief updating

    Erin J Reed et al.
    Paranoia is underwritten by variation in prior beliefs about how the world will change and how to learn from those changes.

    Dopaminergic modulation of the exploration/exploitation trade-off in human decision-making

    Karima Chakroun et al.
    Dopamine attenuates exploration during decision-making via a reduction of neural tracking of uncertainty.
    1. Neuroscience

    Integrating prediction errors at two time scales permits rapid recalibration of speech sound categories

    Itsaso Olasagasti, Anne-Lise Giraud
    Keeping flexible adaptable representations of speech categories at different time scales allows the brain to maintain stable perception in the face of varying speech sound characteristics.
    1. Neuroscience

    Catecholaminergic modulation of meta-learning

    Jennifer L Cook et al.
    A human psychopharmacology study reveals that a drug that affects the dopamine and noradrenaline systems enhances people's ability to adapt their learning rate to suit the volatility of the environment.
    1. Evolutionary Biology

    Multifactorial processes underlie parallel opsin loss in neotropical bats

    Alexa Sadier et al.
    Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
