  1. Donald Hoffman (2008). Conscious Realism and the Mind-Body Problem. Mind and Matter 6 (1):87-121.
    Despite substantial efforts by many researchers, we still have no scientific theory of how brain activity can create or be con- scious experience. This is troubling since we have a large body of correlations between brain activity and consciousness, correlations normally assumed to entail that brain activity creates conscious experience. Here I explore a solution to the mind-body problem that starts with the converse assumption: these correlations arise because consciousness creates brain activity and indeed creates all objects and properties of (...)

  2. Donald D. Hoffman (2006). The Scrambling Theorem: A Simple Proof of the Logical Possibility of Spectrum Inversion. Consciousness and Cognition 15 (1):31-45.
    The possibility of spectrum inversion has been debated since it was raised by Locke and is still discussed because of its implications for functionalist theories of conscious experience . This paper provides a mathematical formulation of the question of spectrum inversion and proves that such inversions, and indeed bijective scramblings of color in general, are logically possible. Symmetries in the structure of color space are, for purposes of the proof, irrelevant. The proof entails that conscious experiences are not identical with (...)

  4. Donald D. Hoffman (2003). Does Perception Replicate the External World? Behavioral and Brain Sciences 26 (4):415-416.
    Vision scientists standardly assume that the goal of vision is to recover properties of the external world. Lehar's “miniature, virtual-reality replica of the external world inside our head” (target article, sect. 10) is an example of this assumption. I propose instead, on evolutionary grounds, that the goal of vision is simply to provide a useful user interface to the external world.

    What differentiates expressions of pain from other facial expressions? Which facial features convey the most information in an expression of pain? To answer such questions we can explore the expertise of human observers using psychophysical experiments. Techniques such as change detection and visual search can advance our understanding of facial expressions of pain and of evolved mechanisms for detecting these expressions.

  8. Todd R. Davies, Donald D. Hoffman & Agustin M. G. Rodriguez (2002). Visual Worlds: Construction or Reconstruction? Journal of Consciousness Studies 9 (5-6):72-87.
    Psychophysical studies of change blindness indicate that, at any instant, human observers are aware of detail in few parts of the visual field. Such results suggest, to some theorists, that human vision reconstructs only a few portions of the visual scene and that, to bridge the resulting representational gaps, it often lets physical objects serve as their own short-term memory. We propose that human vision reconstructs no portion of the visual scene, and that it never lets physical objects serve as (...)

    Pylyshyn's target article argues that perception is not inferential, but this is true only under a narrow construal of inference. A more general construal is possible, and has been used to provide formal theories of many visual capacities. This approach also makes clear that the evolution of natural constraints need not converge to the “veridical” state of the world.

    It is fruitful to think of the representational and the organism-centered approaches as complementary levels of analysis, rather than mutually exclusive alternatives. Claims to the contrary by proponents of the organism-centered approach face what we call the “basketball problem.”.
