Guess who? Facial expressions can cause confusion

(University of Bristol) Photos of the same person can look substantially different. For example, your passport photo may look quite different from your driving license, or your face in holiday photos. Research has shown when photos of an individual's face are judged too dissimilar to go together, people will tend to think they show several different identities. Scientists from the University of Bristol tested this concept further by exploring what happens when the photos show faces with different expressions.
