A Close Eye on the Eagle-Eyed Visual Acuity Hypothesis of Autism / Sven BÖLTE in Journal of Autism and Developmental Disorders, 42-5 (May 2012)
[article]
Titre : A Close Eye on the Eagle-Eyed Visual Acuity Hypothesis of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Sabine SCHLITT, Auteur ; Volker GAPP, Auteur ; Daniela HAINZ, Auteur ; Shella SCHIRMAN, Auteur ; Fritz POUSTKA, Auteur ; Bernhard WEBER, Auteur ; Christine M. FREITAG, Auteur ; Angela CIARAMIDARO, Auteur ; Henrik WALTER, Auteur Année de publication : 2012 Article en page(s) : p.726-733 Langues : Anglais (eng) Mots-clés : Autism Schizophrenia Vision Attention Sensory processing Bottom-up Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASD) have been associated with sensory hypersensitivity. A recent study reported visual acuity (VA) in ASD in the region reported for birds of prey. The validity of the results was subsequently doubted. This study examined VA in 34 individuals with ASD, 16 with schizophrenia (SCH), and 26 typically developing (TYP). Participants with ASD did not show higher VA than those with SCH and TYP. There were no substantial correlations of VA with clinical severity in ASD or SCH. This study could not confirm the eagle-eyed acuity hypothesis of ASD, or find evidence for a connection of VA and clinical phenotypes. Research needs to further address the origins and circumstances associated with altered sensory or perceptual processing in ASD.

Titre : Communicative intentions in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Magdalena SCHÜTZ, Auteur ; Angela CIARAMIDARO, Auteur ; Anne MARTINELLI, Auteur ; Ramona ÖLLER, Auteur ; Daniela HARTMANN, Auteur ; Grit HEIN, Auteur ; Vassil IOTZOV, Auteur ; Livia COLLE, Auteur ; Cristina BECCHIO, Auteur ; Henrik WALTER, Auteur ; Christine M. FREITAG, Auteur Article en page(s) : 101666 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder fMRI Intention Communication Social interaction Index. décimale : PER Périodiques Résumé : Background Deficits in social communication and interaction are among the core symptoms of Autism Spectrum Disorder (ASD). Intention understanding in particular has been shown to be impaired in ASD. However, only one previous study has explicitly assessed the understanding of communicative intentions in ASD. Thus, the aim of the present study was to compare neural activation during the observation of communicative and non-communicative actions in participants with ASD and typically developing (TD) controls using functional magnetic resonance imaging (fMRI). Based on recent findings that show that the degree of involvement of the observer has an impact on neural activation, the present study included first- and third-person perspective stimuli. Method Twenty-five male TD (mean age 20.41?±?3.39) and twenty-two male participants with ASD (mean age 18.60?±?3.55) were included. Stimuli consisted of videos in which actors performed an action with an everyday object. Actions were either private or communicative; communicative actions were either directed at the observer (first-person) or at a third person. Results The ASD group showed reduced activation in the human middle temporal complex (hMT+) across all conditions. However, modulation of activation in response to different conditions remained intact in ASD. Additionally, while TD showed an increase in premotor cortex (PMC) activation in response to communicative actions directed at them, the ASD group showed a decrease in activation. Conclusions These findings suggest an early processing deficit with regard to human biological motion in ASD. Furthermore, results reflect a reduced preparedness for social interactions in ASD compared to TD when addressed directly.

Titre : Executive and Visuo-motor Function in Adolescents and Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Michael SACHSE, Auteur ; Sabine SCHLITT, Auteur ; Daniela HAINZ, Auteur ; Angela CIARAMIDARO, Auteur ; Shella SCHIRMAN, Auteur ; Henrik WALTER, Auteur ; Fritz POUSTKA, Auteur ; Sven BÖLTE, Auteur ; Christine M. FREITAG, Auteur Article en page(s) : p.1222-1235 Langues : Anglais (eng) Mots-clés : Autism Executive functions Reaction time Movement time Information processing CANTAB Index. décimale : PER Périodiques Résumé : This study broadly examines executive (EF) and visuo-motor function in 30 adolescent and adult individuals with high-functioning autism spectrum disorder (ASD) in comparison to 28 controls matched for age, gender, and IQ. ASD individuals showed impaired spatial working memory, whereas planning, cognitive flexibility, and inhibition were spared. Pure movement execution during visuo-motor information processing also was intact. In contrast, execution time of reading, naming, and of visuo-motor information processing tasks including a choice component was increased in the ASD group. Results of this study are in line with previous studies reporting only minimal EF difficulties in older individuals with ASD when assessed by computerized tasks. The finding of impaired visuo-motor information processing should be accounted for in further neuropsychological studies in ASD.
