(A) Representation of the stimuli used in the lateral masking paradigm to study lateral interactions. (B) Representation of the flankers with varying levels of contrast. The contrast of the flankers was calculated by measuring the contrast threshold for an isolated Gabor patch. The threshold value is then multiplied by selected values to test the model of Zenger and Sagi. (C) Representation of the stimuli used in the experiments. (D) Representation of the experimental procedure (2 interval forced choice, 2IFC). (E) Expected results according to the model of Zenger and Sagi.
