Science (New York, N.Y.)·2008

Facial distinctiveness, or how much a face deviates from average, correlates with how unique it appears. However, this physical deviation shows weaker links to how well faces are remembered.

Area of Science:

  • Cognitive Psychology
  • Facial Recognition
  • Perceptual Science

Background:

  • Facial distinctiveness is a key aspect of social perception.
  • Understanding the relationship between objective facial features and subjective perception is crucial.
  • Previous theories suggest a link between facial typicality/distinctiveness and memory.

Purpose of the Study:

  • To investigate the correlation between objective facial deviation from average and rated facial distinctiveness.
  • To examine the relationship between physical facial deviation and memory for faces.
  • To test the Vokey and Read (1992) theory on facial typicality/distinctiveness components.

Main Methods:

  • Objective measurement of facial deviation from an average face.
  • Subjective ratings of facial distinctiveness with hair concealed.

  • Memory tests (hits and false positives) after initial study of faces.
  • Main Results:

    • Reasonable correlation found between physical facial deviation and rated distinctiveness when hair is concealed.
    • More modest correlations observed between physical deviation and face memorability (correct recall and false recognition).
    • Memory performance (hits and false positives) did not correlate negatively as expected, but both correlated with distinctiveness.

    Conclusions:

    • Objective facial deviation is a significant predictor of perceived distinctiveness.
    • The link between physical facial deviation and memory is weaker than its link to distinctiveness.
    • Findings support the theory of orthogonal components of typicality/distinctiveness: memorability and context-free familiarity.
