Les
déficits en communication sociale, en particulier le langage
pragmatique, sont caractéristiques des personnes atteintes de troubles
du spectre autistique (TSA).Les
analyses ont montré que les enfants avec TSA produisaient un
rapport plus élevé entre le contenu et les disfluences que les enfants
au développement typique (TD). Les
fréquences relatives des répétitions, des révisions et des faux départs
ne différaient pas significativement entre les groupes.

Abstract
Deficits in social communication, particularly pragmatic language, are characteristic of individuals with autism spectrum disorder
(ASD). Speech disfluencies may serve pragmatic functions such as cueing
speaking problems. Previous studies have found that speakers with ASD
differ from typically developing (TD) speakers in the types and patterns
of disfluencies they produce, but fail to provide sufficiently detailed
characterizations of the methods used to categorize and quantify
disfluency, making cross-study comparison difficult. In this study we
propose a simple schema for classifying major disfluency types, and use
this schema in an exploratory analysis of differences in disfluency
rates and patterns among children with ASD compared to TD and language
impaired (SLI) groups. 115 children ages 4-8 participated in the study
(ASD = 51; SLI = 20; TD = 44), completing a battery of experimental
tasks and assessments. Measures of morphological and syntactic
complexity, as well as word and disfluency counts, were derived from
transcripts of the Autism
Diagnostic Observation Schedule (ADOS). High inter-annotator agreement
was obtained with the use of the proposed schema. Analyses showed ASD
children produced a higher ratio of content to filler disfluencies than
TD children. Relative frequencies of repetitions, revisions, and false
starts did not differ significantly between groups. TD children also
produced more cued disfluencies than ASD children.
