I Never Forget A Face I Never Forget A Face Presentation Transcript

  • Research on understanding face recognition I never forget a face
  • Never forget a face?
    • Research: Face recognition skill may vary widely, following a spectrum
    • Prosopagnosics at one end (no skill)
    • Super-recognizers at other end (easily recognize, even after years)
    • Reason why this is a “new” phenomena? Only recently have we interacted with such large numbers of people over our lifetime.
    • Research conduced by U.S. National Eye Institute and the U.K. Economic & Social Research Council

  • Are you face blind?
    • Research: Emotional information in the face increases neural activity in area of brain associated with face recognition. Problems in face recognition may lie in cortical part of brain.
    • Scientists say that emotional stimuli can trigger higher level of arousal and emotion in face, which adds additional information for recognizing faces in prosopagnosics.
    • Conclusion: Emotional information in face processing important.

  • The Nose knows
    • Research: During face recognition, first two places we look at are around the nose, with first fixation being slightly to left of nose.
    • Two fixations are optimal for face recognition.
    • Second fixation allows for more information from a different location
    • The nose may be the center of attention (according to researchers)
    • http://www.sciencedaily.com/releases/2008/10/081020171452.htm
  • The eyes have it
    • Research: Brain extracts information for face recognition primarily from eyes, then from mouth and nose.
    • Most useful information is from images of around 30 X 30 pixels
    • Images of eyes are least “noisy” (more reliable than mouth and nose)
    • http://www.sciencedaily.com/releases/2009/03/090326215054.htm
  • It takes two
    • Research: The image of our own face can change through shared experiences with other people’s faces
    • While watching the face of another person being touched as their face was touched (as in a mirror), their ability to recognize their own face was not as consistent.
    • Later, when asked to recognize picture of own face, they tended to include features of face that they saw earlier.
    • Conclusion: sharing experience with another person may change own perception, may relate to our self identify, and with those who have appearance-related concerns.
