Attentional status of faces for people with autism spectrum disorder / Anna REMINGTON in Autism, 16-1 (January 2012)

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.

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? / Tanya DENMARK in Journal of Autism and Developmental Disorders, 44-10 (October 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-10 (October 2014) . - p.2584-2592 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.

Young Children with Autism Spectrum Disorder Do Not Preferentially Attend to Biological Motion / Dagmara ANNAZ in Journal of Autism and Developmental Disorders, 42-3 (March 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-3 (March 2012) . - p.401-408 Titre : Young Children with Autism Spectrum Disorder Do Not Preferentially Attend to Biological Motion Type de document : Texte imprimé et/ou numérique Auteurs : Dagmara ANNAZ, Auteur ; Ruth CAMPBELL, Auteur ; Mike COLEMAN, Auteur ; Elizabeth MILNE, Auteur ; John SWETTENHAM, Auteur Année de publication : 2012 Article en page(s) : p.401-408 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Social stimuli  Attention  Biological motion Index. décimale : PER Périodiques Résumé : Preferential attention to biological motion can be seen in typically developing infants in the first few days of life and is thought to be an important precursor in the development of social communication. We examined whether children with autism spectrum disorder (ASD) aged 3–7 years preferentially attend to point-light displays depicting biological motion. We found that children with ASD did not preferentially attend to biological motion over phase-scrambled motion, but did preferentially attend to a point-light display of a spinning top rather than a human walker. In contrast a neurotypical matched control group preferentially attended to the human, biological motion in both conditions. The results suggest a core deficit in attending to biological motion in ASD.
