Faire une suggestion Affiner la rechercheAttentional status of faces for people with autism spectrum disorder / Anna REMINGTON in Autism, 16-1 (January 2012)
Titre : Attentional status of faces for people with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Anna REMINGTON, Auteur ; Ruth CAMPBELL, Auteur ; John SWETTENHAM, Auteur Année de publication : 2012 Article en page(s) : p.59-73 Langues : Anglais (eng) Mots-clés : face processing selective attention perception Index. décimale : PER Périodiques Résumé : In recent years there has been a growing interest in the role of attention in the processing of social stimuli in individuals with autism spectrum disorders (ASD). Research has demonstrated that, for typical adults, faces have a special status in attention and are processed in an automatic and mandatory fashion even when participants attempt to ignore them. Under conditions of high load in a selective attention task, when irrelevant stimuli are usually not processed, typical adults continue to process distractor faces. Although there is evidence of a lack of attentional bias towards faces in ASD, there has been no direct test of whether faces are processed automatically using the distractor-face paradigm.In the present study 16 typical adults and 16 adults with ASD performed selective attention tasks with face and musical instrument distractors. The results indicated that even when the load of the central task was high, typical adults continued to be distracted by irrelevant face stimuli, whereas individuals with ASD were able to ignore them. In the equivalent non-social task, distractors had no effect at high load for either group. The results suggest that faces are processed in an automatic and mandatory fashion in typical adults but not in adults with ASD.

Titre : Autism Spectrum Disorders at 20 and 42 Months of Age: Stability of Clinical and ADI-R Diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Antony COX, Auteur ; Kate KLEIN, Auteur ; Tony CHARMAN, Auteur ; Gillian BAIRD, Auteur ; Simon BARON-COHEN, Auteur ; John SWETTENHAM, Auteur ; Auriol DREW, Auteur ; Sally WHEELWRIGHT, Auteur Année de publication : 1999 Article en page(s) : p.719-732 Langues : Anglais (eng) Mots-clés : Autism pervasive developmental disorder diagnosis Autism Diagnostic Interview-Revised stability Index. décimale : PER Périodiques Résumé : The association between, and stability of, clinical diagnosis and diagnosis derived from the Autism Diagnostic Interview-Revised (ADI-R; Lord, Rutter, & Le Couteur, 1994) was examined in a sample of prospectively identified children with childhood autism and other pervasive developmental disorders assessed at the age of 20 months and 42 months. Clinical diagnosis of autism was stable, with all children diagnosed with childhood autism at age 20 months receiving a diagnosis of childhood autism or a related pervasive developmental disorder (PDD) at age 42 months. Clinical diagnosis of childhood autism was also reasonably sensitive, with all children who went on to receive a clinical diagnosis of childhood autism at 42 months being identified as having autism or PDD at 20 months. However, clinical diagnosis for PDD and Asperger's syndrome lacked sensitivity at 20 months, with several children who subsequently received these diagnoses at 42 months receiving diagnoses of language disorder or general developmental delay, as well as in two cases being considered clinically normal, at the earlier timepoint. The ADI-R was found to have good specificity but poor sensitivity at detecting childhood autism at 20 months; however, the stability of diagnosis from 20 to 42 months was good. In addition, the ADI-R at age 20 months was not sensitive to the detection of related PDDs or Asperger's syndrome. The continuity and discontinuity between behavioural abnormalities identified at both timepoints in the three domains of impairment in autism was examined, both in children who met final clinical criteria for an autistic spectrum disorder, and for children with language disorder who did not, as well as for a small sample of typically developing children.

Titre : Children with Autism Show Local Precedence in a Divided Attention Task and Global Precedence in a Selective Attention Task Type de document : Texte imprimé et/ou numérique Auteurs : Kate C. PLAISTED, Auteur ; John SWETTENHAM, Auteur ; Liz REES, Auteur Année de publication : 1999 Article en page(s) : p.733-742 Langues : Anglais (eng) Mots-clés : Attention autistic disorder perception Index. décimale : PER Périodiques Résumé : Children with a diagnosis of autism and typically developing children were given two variations of the Navon task (Navon, 1977), which required responding to a target that could appear at the global level, the local level, or both levels. In one variation, the divided attention task, no information was given to children regarding the level at which a target would appear on any one trial. In the other, the selective attention task, children were instructed to attend to either the local or the global level. Typically developing children made most errors when the target appeared at the local level whereas children with autism made more errors when the target appeared at the global level in the divided attention task. Both groups of children were quicker to respond to the global target than the local target in the selective attention task. The presence of normal global processing in the children with autism in one task but not in the other is discussed in terms of a deficit in mechanisms that inhibit local information in the absence of overt priming or voluntary selective attention to local information.

Titre : How do Typically Developing Deaf Children and Deaf Children with Autism Spectrum Disorder Use the Face When Comprehending Emotional Facial Expressions in British Sign Language? Type de document : Texte imprimé et/ou numérique Auteurs : Tanya DENMARK, Auteur ; Joanna ATKINSON, Auteur ; Ruth CAMPBELL, Auteur ; John SWETTENHAM, Auteur Article en page(s) : p.2584-2592 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Deafness Sign language Emotion Facial expression Index. décimale : PER Périodiques Résumé : Facial expressions in sign language carry a variety of communicative features. While emotion can modulate a spoken utterance through changes in intonation, duration and intensity, in sign language specific facial expressions presented concurrently with a manual sign perform this function. When deaf adult signers cannot see facial features, their ability to judge emotion in a signed utterance is impaired (Reilly et al. in Sign Lang Stud 75:113–118, 1992). We examined the role of the face in the comprehension of emotion in sign language in a group of typically developing (TD) deaf children and in a group of deaf children with autism spectrum disorder (ASD). We replicated Reilly et al.’s (Sign Lang Stud 75:113–118, 1992) adult results in the TD deaf signing children, confirming the importance of the face in understanding emotion in sign language. The ASD group performed more poorly on the emotion recognition task than the TD children. The deaf children with ASD showed a deficit in emotion recognition during sign language processing analogous to the deficit in vocal emotion recognition that has been observed in hearing children with ASD.
