Simultaneous orientation contrast for lines in the human fovea

摘要: Abstract When it is surrounded by lines of a differing orientation, test line changes its apparent orientation in direction away from that the surround lines. Using nulling technique to arrive at numerical values, properties this simultaneous contrast have been analyzed: diminishes with distance lines; rises and then falls off as function orientation; decreases exposure duration; sharply tuned (± 100msec) for synchrony presentation; robust differences between disparity but not intensity; reduced dichoptic presentation Orientation can be induced variety oriented features, including illusory contours, an ellipse, moving dot row dots or lines, two alone don't suffice. The results are taken evidence domain sui generis, which exhibited same manner domains color, brightness disparity.
