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.

  • The amygala serves a critical function in emotion recognition and processing, and thus it has been implicated in the neurophysiology of autism. For example, individuals with autism have been found to display atypical amygdala growth processes from childhood into adolescence (see for example Nacewiz et al., 2006. Archives of General Psychiatry, 63,12).
  • The Amygdale's bilateral biochemical functioning was obtained via magnetic resonance spectroscopy. Four metabolites were measured: N-acetyl aspartate (NAA), creatine/Phosphocreatine (Cre), choline (Cho), and myoinositol (ml).
  • The authors did not find any differences in the concentrations of any of the metabolites when comparing the HFA and the control groups
  • ...4 more annotations...
  • However, among the individuals with HFA, NAA was significantly associated with communication impairments, as measured by the ADI. In addition, Cre and NAA were associated with restrictive interests, and Cre alone was associated with social difficulties. The results therefore, indicate that those with the lowest concentrations of these metabolites tended to have more severe clinical symptoms as reported by the ADI.
  • The results of this study provide support for the need to conduct examinations that go beyond simple group comparisons.
  • key metabolites, while observed at normative levels, play a key role in the clinical presentation of the disorder.
  • presence of normative functioning in a particular domain or brain process (when compared to typical peers) does not necessarily indicate that such domain is not implicated in the phenomenology of the condition.

    Amygdala, autism and clinical impairment: When group comparisons are not enough. The results of this study provide support for the need to conduct examinations that go beyond simple group comparisons. In this case, the authors found no differences in any of the metabolites between the two groups, which could easily lead one to conclude that such metabolites may not play a role in autism. Yet, the results were strong in indicating that key metabolites, while observed at normative levels, play a key role in the clinical presentation of the disorder.

autism diagnosis

  • Studies such as this point out the problems of using only behavioral criteria to make the diagnosis of autism. In this study, a multidisciplinary team consisting for child psychiatrists, child psychologists, and speech therapists were used to make the diagnosis. With no hubris intended, we think a neurologist should be included on every autism team. Understanding the specific neurological challenges a child faces can help much more than a more one-size-fits-all approach to intervention.
  • When we have assessed children with an autism or possible autism diagnosis, we have seen the same very wide clinical variation in terms of neurological exam - you would not treat a child with visual processing disorders with purely behavioral modification, nor a child with auditory and language processing problems with facial recognition training.
  • Historically, autism was first recognized as an entity by a psychiatrist, but as it becomes even more clear that the behavioral label subsumes many different neurological conditions, it's time for business-as-usual to come to an end.

autism savant syndrome perception creativity pattern recognition redintegration

shared by Tero Toivanen on 24 Apr 09 - Cached
  • utistic perception is characterized by: enhanced low-level operations; locally oriented processing as a default setting; greater activation of perceptual areas during a range of visuospatial, language, working memory or reasoning tasks; autonomy towards higher processes; and superior involvement in intelligence.
  • We now propose that enhanced detection of patterns, including similarity within and among patterns, is one of the mechanisms responsible for operations on human codes, a type of material with which savants show particular facility.
  • A second mechanism, related to but exceeding the existing concept of redintegration, involves completion, or filling-in, of missing information in memorized or perceived units or structures.
