autism eyes aversion face recognition

  • A brief review of Annaz, D., Karmiloff-Smith, A., Johnson, M., & Thomas, M. (2009). A cross-syndrome study of the development of holistic face recognition in children with autism, Down syndrome, and Williams syndrome Journal of Experimental Child Psychology, 102 (4), 456-486 DOI: 10.1016/j.jecp.2008.11.005
  • 33 kids with autism
  • 15 children with Williams syndrome
  • ...5 more annotations...
  • 15 children with down’s syndrome
  • 25 typically developing children
  • The authors found that all three diagnostic groups showed anomalies in the development of face recognition when compared to typically developing kids.
  • The children with low (but not high) functioning autism show a disadvantage for identifying eyes but an advantage for identifying mouths. In addition, they were better at identifying eyes and noses when the these were upside down than when they were upside up. This is the opposite of what is expected in typically developing children.
  • The authors discussed how this may be due to an aversion to looking directly at eyes, especially in upright faces. Therefore, the observed deficiencies in face recognition among the low functioning autism group may not be due to problems in the development of whole face recognition processes per se, but instead this weakness may be due to a natural aversion to stare at the eyes area of the face.

    Regular readers of this blog will know that I subscribe to the incentive salience theory of doapmaine propounded by Berridge et al. As per this theory dopamine mediates the salience of an internal/ external stimulus and endows and activates the motivational salience related to that stimulus. In simple words the mesolimbic dopamine systems serves to identify the importance of a stimulus to us- be it aversive or pleasurable.
