Recognition without face identification

Recognition without identification is the finding that participants can recognize recognition test items as having been previously studied when the test items themselves are presented in such a way that their identification is hindered. The present study demonstrates this phenomenon in face recognition. Participants studied names of celebrities before receiving a recognition test containing pictures of celebrity faces. Half of the pictures were of celebrities whose names were studied, half were of celebrities whose names were not studied. Participants attempted to identify each face on the test and also rated the likelihood that each person's name was studied. Among the faces that went unidentified, ratings discriminated between celebrities whose names were studied and celebrities whose names were not studied. This recognition without face identification effect is dependent upon the sense of being in a tip-of-the-tongue state for a particular name. Theoretical implications of the results are discussed.
