Description: 
Visual masking is the reduction or elimination of the visibility one brief (? 50 ms) stimulus, called the “target”, by the presentation of a second brief stimulus, called the “mask”. Introduced near the end of the 19th and beginning of the 20th century (Exner, 1868; McDougal, 1904; Sherrington, 1897; Stigler, 1911) and extensively studied since then, masking, an interesting phenomenon in its own right, is a useful tool for exploring the dynamics of visual information processing (Breitmeyer & ??men, 2006). As a technique for studying the dynamic and microgenetic aspects of vision, masking rests on the following assumptions: an interval, on the order of a few tens to two or three hundreds of milliseconds, is required from onset of a stimulus to its measurable effects on behavior or its conscious awareness; the information conveyed by a stimulus is actively processed during this interval; the processing can occur in several specialized, multi-level visual pathways; the responses to the mask and the target can interact at specifiable levels of processing.
