    A Signal Detection Theoretic Approach for Estimating Metacognitive Sensitivity From Confidence Ratings.Brian Maniscalco & Hakwan Lau - 2012 - Consciousness and Cognition 21 (1):422-430.
    How should we measure metacognitive sensitivity, i.e. the efficacy with which observers’ confidence ratings discriminate between their own correct and incorrect stimulus classifications? We argue that currently available methods are inadequate because they are influenced by factors such as response bias and type 1 sensitivity . Extending the signal detection theory approach of Galvin, Podd, Drga, and Whitmore , we propose a method of measuring type 2 sensitivity that is free from these confounds. We call our measure meta-d′, which reflects (...)

  5. The Emperor's New Phenomenology? The Empirical Case for Conscious Experience Without First-Order Representations.Hakwan Lau & Richard Brown - forthcoming - In Adam Pautz & Daniel Stoljar (eds.), Themes from Block. MIT Press.
    We discuss cases where subjects seem to enjoy conscious experience when the relevant first-order perceptual representations are either missing or too weak to account for the experience. Though these cases are originally considered to be theoretical possibilities that may be problematical for the higher-order view of consciousness, careful considerations of actual empirical examples suggest that this strategy may backfire; these cases may cause more trouble for first-order theories instead. Specifically, these cases suggest that (I) recurrent feedback loops to V1 are (...)

  6. Volition and the Function of Consciousness.Hakwan Lau - 2009 - Faith and Philosophy 26 (5):537-552.
    People have intuitively assumed that many acts of volition are not influenced by unconscious information. However, the available evidence suggests that under suitable conditions, unconscious information can influence behavior and the underlying neural mechanisms. One possibility is that stimuli that are consciously perceived tend to yield strong signals in the brain, and this makes us think that consciousness has the function of sending such strong signals. However, if we could create conditions where the stimuli could produce strong signals but not (...)

  7. A Higher Order Bayesian Decision Theory of Consciousness.Hakwan Lau - 2008 - In Rahul Banerjee & B. K. Chakrabarti (eds.), Models of Brain and Mind: Physical, Computational, and Psychological Approaches. Elsevier.
    It is usually taken as given that consciousness involves superior or more elaborate forms of information processing. Contemporary models equate consciousness with global processing, system complexity, or depth or stability of computation. This is in stark contrast with the powerful philosophical intuition that being conscious is more than just having the ability to compute. I argue that it is also incompatible with current empirical findings. I present a model that is free from the strong assumption that consciousness predicts superior performance. (...)

  9. Are We Studying Consciousness Yet?Hakwan Lau - 2008 - In Lawrence Weiskrantz & Martin Davies (eds.), Frontiers of Consciousness. Oxford University Press. pp. 2008--245.
    It has been over a decade and half since Christof Koch and the late Francis Crick first advocated the now popular NCC project (Crick and Koch, 1990), in which one tries to find the neural correlate of consciousness (NCC) for perceptual processes. In his chapter in this book Chris Frith provides a splendid review of how neuroimaging has contributed greatly to this project. For the sake of contrast, this chapter takes a more critical stance on what we have actually learned. (...)

  16. Should Scientists Think?Hakwan Lau - manuscript
    In my field of consciousness research, scientists frequently mock philosophers for their apparent uselessness. There are many issues about which philosophers have debated for centuries, and yet there are no satisfying resolutions. However, sometimes one thinks: what really is philosophy but careful thinking? Certainly that cannot be completely useless? It is therefore particularly refreshing to read Machado and Silva's article in this issue, which emphasizes the role of conceptual analysis in psychological research.

    Broken Telephone in the Brain: The Need for Metacognitive Measures.Hakwan Lau & Navindra Persaud - 2007 - Behavioral and Brain Sciences 30 (5-6):513-514.
    The fact that early visual processing has a larger capacity than later visual processing can be explained without positing distinct systems for phenomenology and cognitive accessibility. While phenomenology may overflow forced-choice reports, the later can also overestimate the former, as in the case of blindsight. Metacognitive measures of awareness offer a way to address the of consciousness research.
