Recognition memory

Memory that occurs when a previously perceived stimulus is re-presented and registered as familiar.  For example, a subject may recognise a voice, face, or visual pattern as being familiar, based on past exposure to it, even though there was no recollection of the stimulus before it was re-presented.  People have excellent recognition memory for faces as they can recognize a person’s face as familiar after lengthy delays.  Considered to require less cognitive effort than recall memory.
