Two stimuli can mutually inhibit {masking, perception}| [Bachmann, 1994] [Bachmann, 2000] [Breitmeyer, 1984] [Breitmeyer and Ögmen, 2000] [Dehaene et al., 2001] [Dennett, 1991] [Enns and DiLollo, 2000] [Flanagan, 1991] [Flanagan, 1992] [Flanagan, 2002] [Keysers and Perrett, 2002] [Keysers et al., 2001] [Macknik and Livingstone, 1998] [Macknik et al., 2000] [Rolls and Tovee, 1994] [Thompson and Schall, 1999] [Thompson and Schall, 2000] [VanRullen and Koch, 2003].
If, after a several-millisecond stimulus, a second stimulus is at the same location, people do not perceive first stimulus {backward masking}. Masking is greatest when second stimulus is 70 milliseconds to 90 milliseconds after first. Second stimulus has no affect after 100 milliseconds. For sound stimulus, second stimulus is noise. If first stimulus causes emotion, emotion results even if stimulus is not conscious.
Masks can precede targets {forward masking}.
Masks can be simultaneous with targets, or masking stimulus can follow short stimulus {metacontrast masking}, to improve detection.
