Three "faces" appear with names. After a brief delay, you're shown one face and asked: was this in the original set?
What makes this one different
Most "face memory" apps ask you to recall names from scratch. That's a recognition-failure trap — most people forget names even when they recognize faces. We use same/different judgments, which are more sensitive to underlying visual memory and less contaminated by name retrieval.
No sessions yet.
Face memory is a well-studied but quirky cognitive ability. We have specialized neural machinery for face processing (the fusiform face area), but it's not the same as general visual memory. The combination of face + name is harder than either alone.
d' (sensitivity) above 1.5 is good. Above 2.0 is strong. Below 0.5 suggests your recognition signal is weak.
False alarms are informative too. High FA + low hits = guessing.
Because most people forget the name even when they recognize the face. Same/different is more sensitive to the underlying visual memory and less contaminated by name retrieval failure.
Face memory varies a lot. If you're consistently below d'=0.5 across multiple sessions, you may want to consult a neuropsychologist — prosopagnosia is more common than people realize.
