    Affine Geometry, Visual Sensation, and Preference for Symmetry of Things in a Thing.Birgitta Dresp-Langley - 2016 - Symmetry 127 (8).
    Evolution and geometry generate complexity in similar ways. Evolution drives natural selection while geometry may capture the logic of this selection and express it visually, in terms of specific generic properties representing some kind of advantage. Geometry is ideally suited for expressing the logic of evolutionary selection for symmetry, which is found in the shape curves of vein systems and other natural objects such as leaves, cell membranes, or tunnel systems built by ants. The topology and geometry of symmetry is (...)

  2. Effects of Saturation and Contrast Polarity on the Figure-Ground Organization of Color on Gray.Birgitta Dresp-Langley & Adam Reeves - 2014 - Frontiers in Psychology 5:1-9.
    Poorly saturated colors are closer to a pure grey than strongly saturated ones and, therefore, appear less “colorful”. Color saturation is effectively manipulated in the visual arts for balancing conflicting sensations and moods and for inducing the perception of relative distance in the pictorial plane. While perceptual science has proven quite clearly that the luminance contrast of any hue acts as a self-sufficient cue to relative depth in visual images, the role of color saturation in such figure-ground organization has remained (...)

  3. Simultaneous Brightness and Apparent Depth From True Colors on Grey: Chevreul Revisited.Birgitta Dresp-Langley & Adam Reeves - 2012 - Seeing and Perceiving 25 (6):597-618.
    We show that true colors as defined by Chevreul (1839) produce unsuspected simultaneous brightness induction effects on their immediate grey backgrounds when these are placed on a darker (black) general background surrounding two spatially separated configurations. Assimilation and apparent contrast may occur in one and the same stimulus display. We examined the possible link between these effects and the perceived depth of the color patterns which induce them as a function of their luminance contrast. Patterns of square-shaped inducers of a (...)

  4. The Communication Contract and Its Ten Ground Clauses.Birgitta Dresp-Langley - 2009 - Journal of Business Ethics 87 (3):415-436.
    Global society issues are putting increasing pressure on both small and large organizations to communicate ethically at all levels. Achieving this requires social skills beyond the choice of language or vocabulary and relies above all on individual social responsibility. Arguments from social contract philosophy and speech act theory lead to consider a communication contract that identifies the necessary individual skills for ethical communication on the basis of a limited number of explicit clauses. These latter are pragmatically binding for all partners (...)

  5. Does Consciousness Exist Independently of Present Time and Present Time Independently of Consciousness.Birgitta Dresp-Langley & Jean Durup - 2012 - Open Journal of Philosophy 2 (1):45-49.
    While some are currently debating whether time may or may not be an illusion, others keep devoting their time to the science of consciousness. Time as such may be seen as a physical or a subjective variable, and the limitations in our capacity of perceiving and analyzing temporal order and change in physical events definitely constrain our understanding of consciousness which, in return, constrains our conceptual under-standing of time. Temporal codes generated in the brain have been considered as the key (...)

    Color and Figure-Ground: From Signals to Qualia.Birgitta Dresp-Langley & Adam Reeves (eds.) - 2014 - Routledge.
    The laws which predict how the perceptual quality of figure-ground can be extracted from the most elementary visual signals were discovered by the Gestaltists, and form an essential part of their movement (see especially Metzger, 1930, and Wertheimer, 1923 translated and re-edited by Lothar Spillmann, 2009 and 2012, respectively). Distinguishing figure from ground is a prerequisite for perception of both form and space (the relative positions, trajectories, and distances of objects in the visual field. The human brain has an astonishing (...)

    Beyond the Classic Receptive Field: The Effect of Contextual Stimuli.Lothar Spillmann, Birgitta Dresp-Langley & Chia-Huei Tseng - 2015 - Journal of Vision 15:1-22.
    Following the pioneering studies of the receptive field (RF), the concept gained further significance for visual perception by the discovery of input effects from beyond the classical RF. These studies demonstrated that neuronal responses could be modulated by stimuli outside their RFs, consistent with the perception of induced brightness, color, orientation, and motion. Lesion scotomata are similarly modulated perceptually from the surround by RFs that have migrated from the interior to the outer edge of the scotoma and in this way (...)

    Why the Brain Knows More Than We Do.Birgitta Dresp-Langley - 2011 - Brain Sciences 2:1-21.
    Scientific studies have shown that non-conscious stimuli and représentations influence information processing during conscious experience. In the light of such evidence, questions about potential functional links between non-conscious brain representations and conscious experience arise. This article discusses models capable of explaining how statistical learning mechanisms in dedicated resonant circuits could generate specific temporal activity traces of non-conscious representations in the brain. How reentrant signaling, top-down matching, and statistical coincidence of such activity traces may lead to the progressive consolidation of neural (...)

  11. 2D Geometry Predicts Perceived Visual Curvature in Context-Free Viewing.Birgitta Dresp-Langley - 2015 - Computational Intelligence and Neuroscience 2015 (708759):1-9.
    Planar geometry was exploited for the computation of symmetric visual curves in the image plane, with consistent variations in local parameters such as sagitta, chordlength, and the curves’ height-to-width ratio, an indicator of the visual area covered by the curve, also called aspect ratio. Image representations of single curves (no local image context) were presented to human observers to measure their visual sensation of curvature magnitude elicited by a given curve. Nonlinear regression analysis was performed on both the individual and (...)
