  An aberrant precision account of autism
  
  Autism is a neurodevelopmental disorder characterized by problems with social-communication, restricted interests and repetitive behavior. A recent and thought-provoking article presented a normative explanation for the perceptual symptoms of autism in terms of a failure of Bayesian inference (Pellicano and Burr, 2012). In response, we suggested that when Bayesian inference is grounded in its neural instantiation—namely, predictive coding—many features of autistic perception can be attributed to aberrant precision (or beliefs about precision) within the context of hierarchical message passing in the brain (Friston et al., 2013). Here, we unpack the aberrant precision account of autism. Specifically, we consider how empirical findings—that speak directly or indirectly to neurobiological mechanisms—are consistent with the aberrant encoding of precision in autism; in particular, an imbalance of the precision ascribed to sensory evidence relative to prior beliefs.

  @ayu_mushi これからのnormになるであろう、みたいな意味では

  @shovel ベイズ統計が推論に関する評価を与えるという意味で規範的(normative)な理論とよく言われるのと関係あるかと思いましたが、この文脈でそれはおかしいのでそういうことかもしれませんね

  @ayu_mushi accountもexplainと似たような意味だから合ってるのでは

  "Our main purpose is to motivate a process theory that equips functionalist or *normative* accounts with a biological mechanism and thereby highlight outstanding questions that, in principle, could be resolved using psychophysical and electrophysiological studies." https://www.frontiersin.org/articles/10.3389/fnhum.2014.00302/full

  @ayu_mushi accountもexplainと似たような意味だから合ってるのでは。既存のfunctionalistか、新しいnorm足り得る記述か。
