  1. Phenomena of Illusory Form: Can We Bridge the Gap Between Levels of Explanation?Lothar Spillmann & Birgitta Dresp - 1995 - Perception 24:1333-1364.
    The major theoretical framework relative to the perception of illusory figures is reviewed and discussed in the attempt to provide a unifying explanatory account for these phenomena.

  2. Interaction of Color and Geometric Cues in Depth Perception: When Does Red Mean "Near"?Christophe Guibal & Birgitta Dresp - 2004 - Psychological Research 69:30-40.
    Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions Under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrasts associated with color contrast interact with relative height in the visual field, partial occlusion, and interposition in determining the probability that a given figure is perceived as ‘‘nearer’’ than another. Latencies of ‘‘near’’ responses were analyzed to test for effects of attentional (...)

  3. Apparent Brightness Enhancement in the Kanizsa Square with and Without Illusory Contours.Birgitta Dresp & Jean Lorenceau - 1990 - Perception 19:483-489.
    The perceived strength of darkness enhancement in the centre of surfaces surrounded or not surrounded by illusory contours was investigated as a function of proximity of the constituent elements of the display and their angular size. Magnitude estimation was used to measure the perception of the darkness phenomenon in white-on-grey stimuli. Darkness enhancement was perceived in both types of the stimuli used, but more strongly in the presence of illusory contours. In both cases, perceived darkness enhancement increased with increasing proximity (...)

  4. Psychophysical Evidence for Low-Level Processing of Illusory Contours and Surfaces in the Kanizsa Square.Birgitta Dresp & Claude Bonnet - 1991 - Vision Research 31:1813-1817.
    Light increment thresholds were measured on either side of one of the illusory contours of a white-on-black Kanizsa square and on the illusory contour itself. The data show that thresholds are elevated when measured on either side of the illusory border. These elevations diminish with increasing distance of the target spot from the white elements which induce the illusory figure. The most striking result, however, is that threshold elevations are considerably lower or even absent when the target is located on (...)

  5. Depth Perception From Pairs of Overlapping Cues in Pictorial Displays.Birgitta Dresp, Severine Durand & Stephen Grossberg - 2002 - Spatial Visions 15:255-276.
    The experiments reported herein probe the visual cortical mechanisms that control near–far percepts in response to two-dimensional stimuli. Figural contrast is found to be a principal factor for the emergence of percepts of near versus far in pictorial stimuli, especially when stimulus duration is brief. Pictorial factors such as interposition (Experiment 1) and partial occlusion Experiments 2 and 3) may cooperate, as generally predicted by cue combination models, or compete with contrast factors in the manner predicted by the FACADE model.

  6. On Illusory Contours and Their Functional Significance.Birgitta Dresp - 1997 - Current Psychology of Cognition 16:489-518.
    This article discusses the reasons why illusory contours are likely to result from adaptive perceptual mechanisms that have evolved across species to promote behavioral success.

  7. Psychophysical Measures of Illusory Form: Further Evidence for Local Mechanisms.Birgitta Dresp & Claude Bonnet - 1993 - Vision Research 33:759-766.
    Detection thresholds for a small light spot were measured at various distances from the colinear inucer edges of white inducing elements on a dark background. The data show that thresholds are elevated when the target is located close to one or more inducing element(s). Threshold elevations diminish with increasing distance of the target from colinear edges and decreasing surface size of the inducing elements. gradients show the same tendencies. Tbe present observations add empirical support to the idea that illusory figures (...)

    A Plastic Temporal Brain Code for Conscious State Generation.Birgitta Dresp & Jean Durup - 2009 - Neural Plasticity 2009:1-15.
    Consciousness is known to be limited in processing capacity and often described in terms of a unique processing stream across a single dimension: time. In this paper, we discuss a purely temporal pattern code, functionally decoupled from spatial signals, for conscious state generation in the brain. Arguments in favour of such a code include Dehaene et al.’s long-distance reverberation postulate, Ramachandran’s remapping hypothesis, evidence for a temporal coherence index and coincidence detectors, and Grossberg’s Adaptive Resonance Theory. A time-bin resonance model (...)
