Visual backward masking is an experimental paradigm used to study information processing in the visual system (Kahneman, 1968). Using this paradigm, minor changes in the temporal intervals between two tachistoscopically presented stimuli produce major changes in the accuracy of perceiving the first (or target) stimulus. In dichoptic masking the target stimulus is presented to one eye and a contoured stimulus (or mask) is presented to the other eye. In monoptic mask ing the target and mask stimuli are presented to the same eye. Monoptic masking is considered to be primarily related to peripheral interactions, while dichoptic masking, because is involves integration beyond the optic chiasm, is considered to be more centrally mediated.
