These attentional mechanisms, however, are not completely independent. Aiming at a more complete picture of spatial attention deficits in ASD, we examined the relationship between orienting and zooming in participants with ASD and typically developing peers. We modified a classical spatial cuing task, presenting two small or large cues in the two visual hemifields and subsequently cueing attention to one of them. Our results demonstrate a sluggish orienting mechanism in ASD only when a large attentional focus is deployed. Moreover, only the sluggish orienting mechanism in the large cues condition predicts the severity in the social-interaction symptomatology in individuals with ASD.

Paternal Autistic Traits are Predictive of Infants Visual Attention / Luca RONCONI in Journal of Autism and Developmental Disorders, 44-7 (July 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-7 (July 2014) . - p.1556-1564 Titre : Paternal Autistic Traits are Predictive of Infants Visual Attention Type de document : texte imprimé Auteurs : Luca RONCONI, Auteur ; Andrea FACOETTI, Auteur ; Hermann BULF, Auteur ; Laura FRANCHIN, Auteur ; Roberta BETTONI, Auteur ; Eloisa VALENZA, Auteur Article en page(s) : p.1556-1564 Langues : Anglais (eng) Mots-clés : Broader autism phenotype  Spatial attention  Temporal attention  Frontoparietal network  Right temporoparietal junction  Social brain development Index. décimale : PER Périodiques Résumé : Since subthreshold autistic social impairments aggregate in family members, and since attentional dysfunctions appear to be one of the earliest cognitive markers of children with autism, we investigated in the general population the relationship between infants’ attentional functioning and the autistic traits measured in their parents. Orienting and alerting attention systems were measured in 8-month-old infants using a spatial cueing paradigm. Results showed that only paternal autistic traits were linked to their children’s: (1) attentional disengagement; (2) rapid attentional orienting and (3) alerting. Our findings suggest that an early dysfunction of orienting and alerting systems might alter the developmental trajectory of future ability in social cognition and communication.

Prolonged neural encoding of visual information in autism / Luca CASARTELLI ; Alessandra FEDERICI ; Sara BERTONI ; Lorenzo VIGNALI ; Massimo MOLTENI ; Andrea FACOETTI ; Luca RONCONI in Autism Research, 17-1 (January 2024)  

Public ISBD [article]  inAutism Research > 17-1 (January 2024) . - p.37-54 Titre : Prolonged neural encoding of visual information in autism Type de document : texte imprimé Auteurs : Luca CASARTELLI, Auteur ; Alessandra FEDERICI, Auteur ; Sara BERTONI, Auteur ; Lorenzo VIGNALI, Auteur ; Massimo MOLTENI, Auteur ; Andrea FACOETTI, Auteur ; Luca RONCONI, Auteur Article en page(s) : p.37-54 Index. décimale : PER Périodiques Résumé : Abstract Autism spectrum disorder (ASD) is associated with a hyper-focused visual attentional style, impacting higher-order social and affective domains. The understanding of such peculiarity can benefit from the use of multivariate pattern analysis (MVPA) of high-resolution electroencephalography (EEG) data, which has proved to be a powerful technique to investigate the hidden neural dynamics orchestrating sensory and cognitive processes. Here, we recorded EEG in typically developing (TD) children and in children with ASD during a visuo-spatial attentional task where attention was exogenously captured by a small (zoom-in) or large (zoom-out) cue in the visual field before the appearance of a target at different eccentricities. MVPA was performed both in the cue-locked period, to reveal potential differences in the modulation of the attentional focus, and in the target-locked period, to reveal potential cascade effects on stimulus processing. Cue-locked MVPA revealed that while in the TD group the pattern of neural activity contained information about the cue mainly before the target appearance, the ASD group showed a temporally sustained and topographically diffuse significant decoding of the cue neural response even after the target onset, suggesting a delayed extinction of cue-related neural activity. Crucially, this delayed extinction positively correlated with behavioral measures of attentional hyperfocusing. Results of target-locked MVPA were coherent with a hyper-focused attentional profile, highlighting an earlier and stronger decoding of target neural responses in small cue trials in the ASD group. The present findings document a spatially and temporally overrepresented encoding of visual information in ASD, which can constitute one of the main reasons behind their peculiar cognitive style.
