  2. Object vs. viewer centered • Object centered • Description of object is independent of where the viewer is location • Structural descriptions are object centered • Locations of parts are specified relative to each other • Viewer centered • Representation changes with position of viewer • Template theories are viewer centered • Template depends on where the viewer is located.

  3. Face recognition • Face recognition seems to be viewer centered • A simple experiment • Do you recognize the famous people in the pictures below? • It may be difficult for you to recognize these people when they are upside-down.

  4. Inversion effects • Faces are harder to recognize when inverted • Like the Beetle, faces do not have good parts.

  5. Indeed, face recognition is odd

  6. More upside down faces http://www.spiralpocus.com/?p=2490

  7. Brain & Face recognition • The temporal lobe of the brain is partly responsible for our ability to recognize faces. • Some neurons in the temporal lobe respond to particular features of faces. • Prosopagnosia (顔面失認症) • Patients who suffer damage to the temporal lobe lose their ability to recognize and identify familiar faces. • When the appearance of a face is changed, neurons in the temporal lobe generate less activity.
