    Continuous flash suppression reduces negative afterimages.Naotsugu Tsuchiya & Christof Koch - 2005 - Nature Neuroscience 8 (8):1096-1101.
    Illusions that produce perceptual suppression despite constant retinal input are used to manipulate visual consciousness. Here we report on a powerful variant of existing techniques, Continuous Flash Suppression. Distinct images flashed successively around 10 Hz into one eye reliably suppress an image presented to the other eye. Compared to binocular rivalry, the duration of perceptual suppression increased more than 10-fold. Using this tool we show that the strength of the negative afterimage of an adaptor was reduced by half when it (...)

  3. Emotion and consciousness.Naotsugu Tsuchiya & Ralph Adolphs - 2007 - Trends in Cognitive Sciences 11 (4):158-167.
    Consciousness and emotion feature prominently in our personal lives, yet remain enigmatic. Recent advances prompt further distinctions that should provide more experimental traction: we argue that emotion consists of an emotion state (functional aspects, including emo- tional response) as well as feelings (the conscious experience of the emotion), and that consciousness consists of level (e.g. coma, vegetative state and wake- fulness) and content (what it is we are conscious of). Not only is consciousness important to aspects of emotion but structures (...)

  10. When do parts form wholes? Integrated information as the restriction on mereological composition.Kelvin J. McQueen & Naotsugu Tsuchiya - forthcoming - Neuroscience of Consciousness.
    Under what conditions are material objects, such as particles, parts of a whole object? This is the composition question and is a longstanding open question in philosophy. Existing attempts to specify a non-trivial restriction on composition tend to be vague and face serious counterexamples. Consequently, two extreme answers have become mainstream: composition (the forming of a whole by its parts) happens under no or all conditions. In this paper, we provide a self-contained introduction to the integrated information theory of consciousness (...)

    Phenomenology Without Conscious Access is A Form of Consciousness Without Top-down Attention.Christof Koch & Naotsugu Tsuchiya - 2007 - Behavioral and Brain Sciences 30 (5-6):509-510.
    We agree with Block's basic hypothesis postulating the existence of phenomenal consciousness without cognitive access. We explain such states in terms of consciousness without top-down, endogenous attention and speculate that their correlates may be a coalition of neurons that are consigned to the back of cortex, without access to working memory and planning in frontal cortex.

    A Quantum Geometric Framework for Modeling Color Similarity Judgments.Gunnar P. Epping, Elizabeth L. Fisher, Ariel M. Zeleznikow-Johnston, Emmanuel M. Pothos & Naotsugu Tsuchiya - 2023 - Cognitive Science 47 (1):e13231.
    Since Tversky argued that similarity judgments violate the three metric axioms, asymmetrical similarity judgments have been particularly challenging for standard, geometric models of similarity, such as multidimensional scaling. According to Tversky, asymmetrical similarity judgments are driven by differences in salience or extent of knowledge. However, the notion of salience has been difficult to operationalize, especially for perceptual stimuli for which there are no apparent differences in extent of knowledge. To investigate similarity judgments between perceptual stimuli, across three experiments, we collected (...)

    When mind and body align: examining the role of cross-modal congruency in conscious representations of happy facial expressions.Thomas Quettier, Elena Moro, Naotsugu Tsuchiya & Paola Sessa - 2024 - Cognition and Emotion 38 (2):267-275.
    This study explored how congruency between facial mimicry and observed expressions affects the stability of conscious facial expression representations. Focusing on the congruency effect between proprioceptive/sensorimotor signals and visual stimuli for happy expressions, participants underwent a binocular rivalry task displaying neutral and happy faces. Mimicry was either facilitated with a chopstick or left unrestricted. Key metrics included Initial Percept (bias indicator), Onset Resolution Time (time from onset to Initial Percept), and Cumulative Time (content stabilization measure). Results indicated that mimicry manipulation (...)

  17. When philosophical nuance matters: safeguarding consciousness research from restrictive assumptions.Marius Usher, Niccolò Negro, Hilla Jacobson & Naotsugu Tsuchiya - 2023 - Frontiers in Psychology 14.
    In this paper, we revisit the debate surrounding the Unfolding Argument (UA) against causal structure theories of consciousness (as well as the hard-criteria research program it prescribes), using it as a platform for discussing theoretical and methodological issues in consciousness research. Causal structure theories assert that consciousness depends on a particular causal structure of the brain. Our claim is that some of the assumptions fueling the UA are not warranted, and therefore we should reject the methodology for consciousness science that (...)
