  1. Tests for consciousness in humans and beyond.Tim Bayne, Anil K. Seth, Marcello Massimini, Joshua Shepherd, Axel Cleeremans, Stephen M. Fleming, Rafael Malach, Jason Mattingley, David K. Menon, Adrian M. Owen, Megan A. K. Peters, Adeel Razi & Liad Mudrik - 2024 - Trends in Cognitive Sciences 29.
    Which systems/organisms are conscious? New tests for consciousness (‘C-tests’) are urgently needed. There is persisting uncertainty about when consciousness arises in human development, when it is lost due to neurological disorders and brain injury, and how it is distributed in nonhuman species. This need is amplified by recent and rapid developments in artificial intelligence (AI), neural organoids, and xenobot technology. Although a number of C-tests have been proposed in recent years, most are of limited use, and currently we have no (...)

  2. To Test the Boundaries of Consciousness, Study Animals.Simon Brown, Elizabeth S. Paul & Jonathan Birch - 2024 - Trends in Cognitive Sciences 28 (10):874-875.
    A letter replying to Bayne et al. "Tests for consciousness in humans and beyond", 2024, arguing that the search for consciousness "beyond" healthy adult humans should begin with other animals.

  3. When visual metacognition fails: widespread anosognosia for visual deficits.Matthias Michel, Yi Gao, Matan Mazor, Isaiah Kletenik & Dobromir Rahnev - 2024 - Trends in Cognitive Sciences.
    Anosognosia for visual deficits—cases where significant visual deficits go unnoticed—challenges the view that our own conscious experiences are what we know best. We review these widespread and striking failures of awareness. Anosognosia can occur with total blindness, visual abnormalities induced by brain lesions, and eye diseases. We show that anosognosia for visual deficits is surprisingly widespread. Building on previous accounts, we introduce a framework showing how apparently disparate forms of anosognosia fit together. The central idea is that, to notice a (...)

    Quality space computations for consciousness.Stephen M. Fleming & Nicholas Shea - 2024 - Trends in Cognitive Sciences.
    The quality space hypothesis about conscious experience proposes that conscious sensory states are experienced in relation to other possible sensory states. For instance, the colour red is experienced as being more like orange, and less like green or blue. Recent empirical findings suggest that subjective similarity space can be explained in terms of similarities in neural activation patterns. Here, we consider how localist, workspace, and higher-order theories of consciousness can accommodate claims about the qualitative character of experience and functionally support (...)

    Empirical approaches to determining quality space computations for consciousness: a response to Dołega et al. and Song.Stephen M. Fleming & Nicholas Shea - 2024 - Trends in Cognitive Sciences.
    Our hope and aim was to provoke debate and research on the hypothesis that conscious experiences form quality spaces [1], so we were very pleased to receive letters from Dołęga, Mentec and Cleeremans [2] and Song [3] making constructive suggestions for taking this enquiry in new directions. Our focus was on how various computational theories of consciousness can accommodate the quality space hypothesis. Dołęga et al. make the helpful observation that this should also be investigated diachronically – both developmentally, and (...)
