Audiovisual speech integration and lipreading in autism / Elizabeth G. SMITH in Journal of Child Psychology and Psychiatry, 48-8 (August 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-8 (August 2007) . - p.813–821 Titre : Audiovisual speech integration and lipreading in autism Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth G. SMITH, Auteur ; Loisa BENNETTO, Auteur Année de publication : 2007 Article en page(s) : p.813–821 Langues : Anglais (eng) Mots-clés : Speech-reception-threshold speech-in-noise audiovisual-speech-integration autism Index. décimale : PER Périodiques Résumé : Background: During speech perception, the ability to integrate auditory and visual information causes speech to sound louder and be more intelligible, and leads to quicker processing. This integration is important in early language development, and also continues to affect speech comprehension throughout the lifespan. Previous research shows that individuals with autism have difficulty integrating information, especially across multiple sensory domains. Methods: In the present study, audiovisual speech integration was investigated in 18 adolescents with high-functioning autism and 19 well-matched adolescents with typical development using a speech in noise paradigm. Speech reception thresholds were calculated for auditory only and audiovisual matched speech, and lipreading ability was measured. Results: Compared to individuals with typical development, individuals with autism showed less benefit from the addition of visual information in audiovisual speech perception. We also found that individuals with autism were significantly worse than those in the comparison group at lipreading. Hierarchical regression demonstrated that group differences in the audiovisual condition, while influenced by auditory perception and especially by lipreading, were also attributable to a unique factor, which may reflect a specific deficit in audiovisual integration. Conclusions: Combined deficits in audiovisual speech integration and lipreading in individuals with autism are likely to contribute to ongoing difficulties in speech comprehension, and may also be related to delays in early language development.

Auditory spatial attention to speech and complex non-speech sounds in children with autism spectrum disorder / Laura N. SOSKEY in Autism Research, 10-8 (August 2017)  

Public ISBD [article]  inAutism Research > 10-8 (August 2017) . - p.1405-1416 Titre : Auditory spatial attention to speech and complex non-speech sounds in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Laura N.

ALLEN, Auteur ; Loisa BENNETTO, Auteur Article en page(s) : p.1405-1416 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  children  auditory spatial attention  acoustic complexity  speech Index. décimale : PER Périodiques Résumé : One of the earliest observable impairments in autism spectrum disorder (ASD) is a failure to orient to speech and other social stimuli. Auditory spatial attention, a key component of orienting to sounds in the environment, has been shown to be impaired in adults with ASD. Additionally, specific deficits in orienting to social sounds could be related to increased acoustic complexity of speech. We aimed to characterize auditory spatial attention in children with ASD and neurotypical controls, and to determine the effect of auditory stimulus complexity on spatial attention. In a spatial attention task, target and distractor sounds were played randomly in rapid succession from speakers in a free-field array. Participants attended to a central or peripheral location, and were instructed to respond to target sounds at the attended location while ignoring nearby sounds. Stimulus-specific blocks evaluated spatial attention for simple non-speech tones, speech sounds (vowels), and complex non-speech sounds matched to vowels on key acoustic properties. Children with ASD had significantly more diffuse auditory spatial attention than neurotypical children when attending front, indicated by increased responding to sounds at adjacent non-target locations. No significant differences in spatial attention emerged based on stimulus complexity. Additionally, in the ASD group, more diffuse spatial attention was associated with more severe ASD symptoms but not with general inattention symptoms. Spatial attention deficits have important implications for understanding social orienting deficits and atypical attentional processes that contribute to core deficits of ASD.

Beyond Pragmatics: Morphosyntactic Development in Autism / Inge-Marie EIGSTI in Journal of Autism and Developmental Disorders, 37-6 (July 2007)

Few studies have examined grammatical abilities in autism, with mixed findings. The present study addresses this gap in the literature by providing a detailed investigation of syntactic and higher-level discourse abilities in verbal children with autism, age 5 years. Findings indicate clear language difficulties that go beyond what would be expected based on developmental level; specifically, syntactic delays, impairments in discourse management and increased production of non-meaningful words (jargon). The present study indicates a highly specific pattern of language impairments, and importantly, syntactic delays, in a group of children with autism carefully matched on lexical level and non-verbal mental age with children with developmental delays and typical development.

Children with autism spectrum disorder have reduced otoacoustic emissions at the 1 kHz mid-frequency region / Loisa BENNETTO in Autism Research, 10-2 (February 2017)

LUEBKE, Auteur Article en page(s) : p.337-345 Langues : Anglais (eng) Mots-clés : DPOAE  distortion-product otoacoustic emissions  TrOAE  transient-evoked otoacoustic emissions  autism  cochlea  efferent suppression  middle ear muscle reflex Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is a behaviorally diagnosed disorder of early onset characterized by impairment in social communication and restricted and repetitive behaviors. Some of the earliest signs of ASD involve auditory processing, and a recent study found that hearing thresholds in children with ASD in the mid-range frequencies were significantly related to receptive and expressive language measures. In addition, otoacoustic emissions have been used to detect reduced cochlear function in the presence of normal audiometric thresholds. We were interested then to know if otoacoustic emissions in children with normal audiometric thresholds would also reveal differences between children with ASD and typical developing (TD) controls in mid-frequency regions. Our objective was to specifically measure baseline afferent otoacoustic emissions (distortion-product otoacoustic emissions [DPOAEs]), transient-evoked otoacoustic emissions (TrOAEs), and efferent suppression, in 35 children with high-functioning ASD compared with 42 aged-matched TD controls. All participants were males 6–17 years old, with normal audiometry, and rigorously characterized via Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. Children with ASD had greatly reduced DPOAE responses in the 1 kHz frequency range, yet had comparable DPOAE responses at 0.5 and 4–8 kHz regions. Furthermore, analysis of the spectral features of TrOAEs revealed significantly decreased emissions in ASD in similar frequencies. No significant differences were noted in DPOAE or TrOAE noise floors, middle ear muscle reflex activity, or efferent suppression between children with ASD and TD controls. In conclusion, attention to specific-frequency deficits using non-invasive measures of cochlear function may be important in auditory processing impairments found in ASD.

Computer Vision Analysis of Reduced Interpersonal Affect Coordination in Youth With Autism Spectrum Disorder / Casey J. ZAMPELLA in Autism Research, 13-12 (December 2020)  

Public ISBD [article]  inAutism Research > 13-12 (December 2020) . - p.2133-2142 Titre : Computer Vision Analysis of Reduced Interpersonal Affect Coordination in Youth With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Casey J. ZAMPELLA, Auteur ; Loisa BENNETTO, Auteur ; John D. HERRINGTON, Auteur Article en page(s) : p.2133-2142 Langues : Anglais (eng) Mots-clés : affect/emotion  computer vision  facial expression  interpersonal coordination  social-emotional reciprocity  synchrony Index. décimale : PER Périodiques Résumé : Atypical social-emotional reciprocity is a core feature of autism spectrum disorder (ASD) but can be difficult to operationalize. One measurable manifestation of reciprocity may be interpersonal coordination, the tendency to align the form and timing of one's behaviors (including facial affect) with others. Interpersonal affect coordination facilitates sharing and understanding of emotional cues, and there is evidence that it is reduced in ASD. However, most research has not measured this process in true social contexts, due in part to a lack of tools for measuring dynamic facial expressions over the course of an interaction. Automated facial analysis via computer vision provides an efficient, granular, objective method for measuring naturally occurring facial affect and coordination. Youth with ASD and matched typically developing youth participated in cooperative conversations with their mothers and unfamiliar adults. Time-synchronized videos were analyzed with an open-source computer vision toolkit for automated facial analysis, for the presence and intensity of facial movements associated with positive affect. Both youth and adult conversation partners exhibited less positive affect during conversations when the youth partner had ASD. Youth with ASD also engaged in less affect coordination over the course of conversations. When considered dimensionally across youth with and without ASD, affect coordination significantly predicted scores on rating scales of autism-related social atypicality, adaptive social skills, and empathy. Findings suggest that affect coordination is an important interpersonal process with implications for broader social-emotional functioning. This preliminary study introduces a promising novel method for quantifying moment-to-moment facial expression and emotional reciprocity during natural interactions. LAY SUMMARY: This study introduces a novel, automated method for measuring social-emotional reciprocity during natural conversations, which may improve assessment of this core autism diagnostic behavior. We used computerized methods to measure facial affect and the degree of affect coordination between conversation partners. Youth with autism displayed reduced affect coordination, and reduced affect coordination predicted lower scores on measures of broader social-emotional skills.
