masking

A term describing any process whereby a detectable stimulus is made difficult or impossible to detect by the presentation of a second stimulus (called the mask). The main stimulus (typically called the target) may appear at the same time as the mask (simultaneous masking); or it may precede the mask (backward masking; example: metacontrast); or it may follow the mask (forward masking; example: paracontrast).
