    • Meta- and paracontrast reveal differences between contour- and brightness-processing mechanisms 

      Breitmeyer, B. G.; Kafalıgönül, Hulusi; Öğmen, H.; Mardon, L.; Todd, S.; Ziegler, R. (Elsevier, 2006)
      We investigated meta- and paracontrast masking using tasks requiring observers to judge the surface brightness or else the contours of target stimuli. The contour task revealed strongest metacontrast at SOAs shorter than ...
    • Metacontrast masking and stimulus contrast polarity 

      Breitmeyer, B.; Tapia, E.; Kafalıgönül, Hulusi; Öğmen, H. (Elsevier, 2008)
      A recent report [Becker, M. W., & Anstis S. (2004). Metacontrast masking is specific to luminance polarity. Vision Research, 44, 2537–2543] of a failure to obtain metacontrast with target and mask stimuli of opposite ...
