    Beyond an occult kinematics of the mind.Keith K. Niall - 2001 - Behavioral and Brain Sciences 24 (4):692-695.
    The evidence for a kinematics of the mind is confounded by uncontrolled properties of pictures. Effects of illumination and of picture-plane geometry may underlie some evidence given for a process of mental rotation. Pictured rotation is confounded by picture similarity, gauged by gray -level correlations. An example is given involving the depicted rotation of Shepard-Metzler solids in depth.

    Erwin Schrödinger's Color Theory: Translated with Modern Commentary.Keith K. Niall (ed.) - 2017 - Cham: Imprint: Springer.
    This book presents the most complete translation to date of Erwin Schrödinger's work on colorimetry. In his work Schrödinger proposed a projective geometry of color space, rather than a Euclidean line-element. He also proposed new (at the time) colorimetric methods - in detail and at length - which represented a dramatic conceptual shift in colorimetry. Schrödinger shows how the trichromatic (or Young-Helmholtz) theory of color and the opponent-process (or Hering) theory of color are formally the same theory, or at least (...)

    Visual imagery and geometric enthymeme: The example of euclid I.Keith K. Niall - 2002 - Behavioral and Brain Sciences 25 (2):202-203.
    Students of geometry do not prove Euclid's first theorem by examining an accompanying diagram, or by visualizing the construction of a figure. The original proof of Euclid's first theorem is incomplete, and this gap in logic is undetected by visual imagination. While cognition involves truth values, vision does not: the notions of inference and proof are foreign to vision.
