    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor, Karl J Friston, Stephen M Fleming
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).

    Decoupling sensory from decisional choice biases in perceptual decision making

    Daniel Linares, David Aguilar-Lleyda, Joan López-Moliner
    Perceptual decision making, even in simple scenarios, is affected by sensory and decisional choice biases.

    Sources of noise during accumulation of evidence in unrestrained and voluntarily head-restrained rats

    Benjamin B Scott, Christine M Constantinople ... Carlos D Brody
    Statistical analysis of evidence-based decisions reveals new insights into the source of behavioral variability.

    Quorums enable optimal pooling of independent judgements in biological systems

    James AR Marshall, Ralf HJM Kurvers ... Max Wolf
    Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

    Distinct neural bases of subcomponents of the attentional blink

    Swagata Halder, Deepak Velgapuni Raya, Devarajan Sridharan
    The attentional blink selectively impairs one component of attention, and impacts both target detection and discrimination via separable neural signatures.
    1. Neuroscience

    Criterion placement threatens the construct validity of neural measures of consciousness

    Johannes Jacobus Fahrenfort, Philippa A Johnson ... Simon van Gaal
    The neural basis of consciousness is confounded by the mismatch between what participants report about their experience versus what they actually experience.
    1. Neuroscience

    Spectral signature and behavioral consequence of spontaneous shifts of pupil-linked arousal in human

    Ella Podvalny, Leana E King, Biyu J He
    Fluctuations of spectral power in large-scale cortical networks shape behavior in a perceptual decision-making task through arousal-linked and arousal-independent mechanisms.
    1. Neuroscience

    Boosts in brain signal variability track liberal shifts in decision bias

    Niels A Kloosterman, Julian Q Kosciessa ... Douglas D Garrett
    Modulation of moment-to-moment irregularity of neural activity closely tracks our ability to flexibly adapt decision biases to the environment.
    1. Neuroscience

    Sensitivity to visual features in inattentional blindness

    Makaela Nartker, Chaz Firestone ... Ian Phillips
    As a group, inattentionally blind participants can successfully report the location, color, and shape of stimuli they deny noticing, and exhibit a systematic bias to report not noticing.
    1. Neuroscience

    Consciousness: Did you see it?

    Ling Liu
    Cautious reporting choices can artificially enhance how well analyses of brain activity reflect conscious and unconscious experiences, making distinguishing between the two more challenging.
