L'autisme est associé à des anomalies sensorielles et cognitives. Les
personnes avec un diagnostic d'autisme présentent généralement des capacités
normales ou supérieures de traitement sensoriel précoce par rapport aux
témoins sans autisme, mais des déficits dans le traitement sensoriel complexe.
Dans ce document, l'auteur soutient
que les anomalies sensorielles influent sur la cognition en limitant la
quantité de signal pouvant être utilisée pour interpréter et interagir
avec l'environnement.

Abstract
Autism is associated with sensory and cognitive abnormalities. Individuals with autism
generally show normal or superior early sensory processing abilities
compared to healthy controls, but deficits in complex sensory
processing. In the current opinion paper, it will be argued that sensory
abnormalities impact cognition by limiting the amount of signal that
can be used to interpret and interact with environment. There is a
growing body of literature showing that individuals with autism
exhibit greater trial-to-trial variability in behavioural and cortical
sensory responses. If multiple sensory signals that are highly variable
are added together to process more complex sensory stimuli, then this
might destabilize later perception and impair cognition. Methods to
improve sensory processing have shown improvements in more general
cognition. Studies that specifically investigate differences in sensory
trial-to-trial variability in autism,
and the potential changes in variability before and after treatment,
could ascertain if trial-to-trial variability is a good mechanism to
target for treatment in autism. This article is protected by copyright. All rights reserved.
