  • Theory guides us in one respect. Kim’s brain shows abnormalities in the left hemisphere, a pattern found in many savants. What is more, left hemisphere damage has been invoked as an explanation of why males are much more likely than females to display not only savantism but also dyslexia, stuttering, delayed speech, and autism.
  • The proposed mechanism has two parts: male fetuses have a higher level of circulating testosterone, which can be toxic to developing brain tissue; and the left hemisphere develops more slowly than the right and therefore remains vulnerable for a longer period. Also supporting the role of left hemisphere damage are the many reported cases of “acquired savant syndrome,” in which older children and adults suddenly develop savant skills after damage to the left hemisphere.
  • although autism is more commonly linked with savantism than is any other single disorder, only about half of all savants are autistic.

  • Mottron team did not shy away from suggesting that the features of savant syndrome could serve as an entryway into understanding all forms of autistic perception and cognition, savant like or not. This effectively removed savant syndrome from being the freak sideshow of autism and elevated it to the status of being a key element for understanding the condition.
  • it is orientation towards structure and pattern that determines the essential characteristics of autistic perception and cognition.
  • Not weak central coherence. Not damaged executive functioning. Not a missing theory of mind. Not a masculinized brain. Orientation to pattern and structure is the key to understanding autistic perception—an approach that is productive towards autistic interests and abilities, not destructive, as is the case for nearly every other competing theory. The Mottron team's emphasis on pattern-oriented perception in autistic individuals is a helpful step forward in understanding autistic individuals as they truly are.

  • all the success stories related inside the pages of EPSS are accompanied by fortuitous exposure to various forms of structured material, clearly marking out the most promising path for autistic development and growth.
  • And of course these discussions fly in the face of the current clamor for early intervention in autism, where it would seem the goal is always to yank the autistic child away as early as possible from his or her preferred method of engaging the world, and substitute instead an intense bombardment of socially based indoctrination, hoping to turn the child around while there is still time for the “malleable” brain to be re-molded.
  • In my opinion, it is no mere coincidence that the very same elements that stand at the core of the Mottron team's affirmative description of autistic perception and cognition are also the very same elements that stand at the core of humanity’s sudden departure off the savannah and leap into the modern world.
  • Admittedly, a thorough discussion of such a topic would be much too large for inclusion in an academic research paper such as EPSS, but the fact that the Mottron team does not mention, or even hint at, the connection between the features of autistic perception and the features of human cognitive history leave it unclear whether the team has ever considered such a connection.
  • At this point in time, the Mottron team seems to be the only autism research team heading in a positive and enlightening direction—a direction that is constructive for autistic individuals everywhere—and I look forward to all their future contributions.

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.
