On the relation between metacontrast masking and suppression of visible persistance.

Does the introduction of additional contours in a display sequence (an operation known to reduce the strength of suppression in metacontrast) also reduce suppression of visible persistence? In three experiments, duration of visible persistence was estimated by a method in which successful performance depends on the temporal integration of a pattern whose elements are displayed in two successive frames. It is concluded that suppression of visible persistence and metacontrast masking belong to the same class of events.
