Metacontrast masking as a function of mask energy

  • Bruno G. Breitmeyer


Two metacontrast experiments investigated the effects of the relation between the energy of a black target disk and the energy of a black annular mask. The resulting masking functions indicate that at short stimulus onset asynchronies (SO As), target contrast suppression requires higher mask energies than are required at intermediate SO As. The relevance of these findings to current sustained-transient channel models of metacontrast is discussed.
