How Does Your Brain Recognize Familiar Faces?

You can recognize a friend even when the lighting, hairstyle or expression changes. Familiar-face recognition connects visual information with what you already know about that person.

The useful part

Research finds contributions from networks involved in visual processing and person knowledge. Recognition is not simply matching a face to one perfectly stored photograph. Recognizing someone and recalling their name can also feel like separate steps.

Try this

Meeting someone new? Pay attention to the conversation as well as the face. Linking a name with a meaningful detail gives you another cue when you meet again.
