  1. Steven Lehar, Editor's Comments.
    April 5, 2002 Dear Dr. Lehar, Your paper still requires substantial revision before it can be published in Perception. This reviewer is now more positive about the paper, but recommends strongly that you cut the first section to at most 2 pages. Please do not submit a revision that is not seriously pruned. Respond carefully to this reviewer because I will send your revision back again for another look before acceptance. When you resubmit this paper, please include a cover letter (...)

  2. Steven Lehar, J. J. Gibson (1966) the Senses Considered as Perceptual Systems. Houghton Mifflin, Boston.
    The very idea of a retinal pattern-sensation that can be impressed on the neural tissue of the brain is a misconception, for the neural pattern never even existed in the retinal mosaic. There can be no anatomical engram in the brain if there was no anatomical image in the retina. The retina jerks about. It has a rapid tremor. It even has a gap in it (the blind spot). It is a scintillation, not an image. An engram impressed on the (...)

  4. Steven Lehar (2003). Alternative Paradigmatic Hypotheses Cannot Be Fairly Evaluated From Within One's Own Paradigmatic Assumptions. Behavioral and Brain Sciences 26 (4):430-439.
    To avoid endless and futile debate, critics of an alternative paradigmatic hypothesis cannot simply state their own paradigmatic assumptions as if they were plain fact while dismissing those of the opposition as self-evidently absurd, because it is exactly those initial assumptions that are brought into question by the paradigmatic proposal. Perceived incredibility is no valid ground for rejection of a paradigm whose alternatives are at least equally incredible, and arguably more so.

    A serious crisis is identified in theories of neurocomputation, marked by a persistent disparity between the phenomenological or experiential account of visual perception and the neurophysiological level of description of the visual system. In particular, conventional concepts of neural processing offer no explanation for the holistic global aspects of perception identified by Gestalt theory. The problem is paradigmatic and can be traced to contemporary concepts of the functional role of the neural cell, known as the Neuron Doctrine. In the absence (...)

  6. Steven Lehar (2003). The World in Your Head: A Gestalt View of the Mechanism of Conscious Experience. Lawrence Erlbaum.
    The World In Your Head: A Gestalt View of the Mechanism of Conscious Experience represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious observation is (...)

  7. Steven Lehar, Computational Implications of Gestalt Theory: The Role of Feedback in Visual Processing.
    Neurophysiological investigations of the visual system by way of single-cell recordings have revealed a hierarchical architecture in which lower level areas, such as the primary visual cortex, contain cells that respond to simple features, while higher level areas contain cells that respond to higher order features apparently composed of combinations of lower level features. This architecture seems to suggest a feed-forward processing strategy in which visual information progresses from lower to higher visual areas. However there is other evidence, both neurophysiological (...)

  8. Steven Lehar (2000). The Dimensions of Conscious Experience: A Quantitative Phenomenology. Consciousness and Cognition 9 (2).
    Psychology was originally formulated as the science of the _psyche_, i.e. the subjective side of the mind / brain barrier. However time and again it has been diverted from this objective in the supposed interest of scientific rigor. The Behaviorists proposed to transform psychology to a science of behavior, and today the Neuroreductionists propose to transform it to a science of neurophysiology. In the process they attempt to deny the very existence of conscious experience as valid object of scientific scrutiny. (...)

    The Gestalt principle of isomorphism reveals the primacy of subjective experience as a valid source of evidence for the information encoded neurophysiologically. This theory invalidates the abstractionist view that the neurophysiological representation can be of lower dimensionality than the percept to which it gives rise.
