  1. Subjective Discriminability of Invisibility: A Framework for Distinguishing Perceptual and Attentional Failures of Awareness.Ryota Kanai, Vincent Walsh & Chia-Huei Tseng - 2010 - Consciousness and Cognition 19 (4):1045-1057.
    Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target . Using this new measure, (...)

    Relating Inter-Individual Differences in Metacognitive Performance on Different Perceptual Tasks.Chen Song, Ryota Kanai, Stephen M. Fleming, Rimona S. Weil, D. Samuel Schwarzkopf & Geraint Rees - 2011 - Consciousness and Cognition 20 (4):1787.
    Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments (...)

    Recognising the Forest, but Not the Trees: An Effect of Colour on Scene Perception and Recognition.Tanja C. W. Nijboer, Ryota Kanai, Edward H. F. de Haan & Maarten J. van der Smagt - 2008 - Consciousness and Cognition 17 (3):741-752.
    Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is ‘diagnostic’. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate (...)
