To test familiarity-based recognition, Cleary gave her subjects a list of celebrity names. Later, they were shown a variety of celebrity photographs. Some of the faces had been on the list of names and some had not. Subjects were asked to identify the people in the photographs and indicate how likely it was that the celebrity's names had been on the earlier list. According to the report, "Even when the volunteers were unable to identify a celebrity by photo, they had a sense of which names they had studied earlier and which they had not. That is, they couldn't identify the source of their familiarity with the celebrity, but they knew the celebrity was familiar to them." Clearly ran the test again using names and photos of famous landmarks in place of celebrities and had similar results. A bit of the memory was there, but, like our friend one too many martinis in at the club, it was hazy and subjects were unable to connect it to the new experience.
