  1. 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 (...)

  2. 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 (...)
