JOHNSON, Auteur Année de publication : 2011 Article en page(s) : p.968-973 Langues : Anglais (eng) Mots-clés : Face recognition  Spatial frequency  Development  Autism  Williams syndrome Index. décimale : PER Périodiques Résumé : The current study investigated whether contrasting face recognition abilities in autism and Williams syndrome could be explained by different spatial frequency biases over developmental time. Typically-developing children and groups with Williams syndrome and autism were asked to recognise faces in which low, middle and high spatial frequency bands were masked. All three groups demonstrated a gradual specialisation toward the mid-band. However, while the use of high spatial frequencies decreased in control and autism groups over development, the Williams syndrome group did not display a bias toward this band at any point. These data demonstrate that typical outcomes can be achieved through atypical developmental processes, and confirm the importance of cross-syndrome studies in the investigation of developmental disorders.

The atypical development of metaphor and metonymy comprehension in children with autism / Gabriella RUNDBLAD in Autism, 14-1 (January 2010)  

Public ISBD [article]  inAutism > 14-1 (January 2010) . - p.29-46 Titre : The atypical development of metaphor and metonymy comprehension in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Gabriella RUNDBLAD, Auteur ; Dagmara ANNAZ, Auteur Année de publication : 2010 Article en page(s) : p.29-46 Langues : Anglais (eng) Mots-clés : autism developmental-trajectories metaphor metonymy pragmatics Index. décimale : PER Périodiques Résumé : One of the most noticeable problems in autism involves the social use of language such as metaphor and metonymy, both of which are very common in daily language use. The present study is the first to investigate the development of metaphor and metonymy comprehension in autism. Eleven children with autism were compared to 17 typically developing children in a metaphor-metonymy comprehension task. Cross-sectional trajectory analyses were used to compare the development of metaphor and metonymy comprehension using a child-friendly story picture task. Trajectories were constructed linking task performance either to chronological age or to measures of mental age. Children with autism showed an impaired metaphor comprehension in relation to both chronological and mental age, whereas performance on metonymy was delayed and in line with their receptive vocabulary. Our results suggest that understanding of metaphors and metonyms are severely affected at all ages examined in the current study.

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.
