The current study examined overt orienting to caregiver-initiated touch in 12-month-olds at high risk for ASD (HRA) with (HRA+) and without (HRA-) a later diagnosis of ASD compared to low-risk comparison infants. Findings indicate that infants that go on to receive a diagnosis of ASD may more frequently fail to shift their attention in response to caregiver touch and when they do, they may be more likely to orient away from touch. Additionally, failure to respond to touch predicts ADOS severity scores at outcome suggesting that atypical response to touch may be an early indicator of autism severity.

Auditory Attentional Disengagement in Children with Autism Spectrum Disorder / B. KEEHN in Journal of Autism and Developmental Disorders, 49-10 (October 2019)

KEEHN, Auteur ; Girija KADLASKAR, Auteur ; R. MCNALLY KEEHN, Auteur ; A. L. FRANCIS, Auteur Article en page(s) : p.3999-4008 Langues : Anglais (eng) Mots-clés : Attention  Auditory  Autism spectrum disorder  Disengagement  Eog  Eye movements Index. décimale : PER Périodiques Résumé : Despite early differences in orienting to sounds, no study to date has investigated whether children with ASD demonstrate impairments in attentional disengagement in the auditory modality. Twenty-one 9-15-year-old children with ASD and 20 age- and IQ-matched TD children were presented with an auditory gap-overlap paradigm. Evidence of impaired disengagement in ASD was mixed. Differences in saccadic reaction time for overlap and gap conditions did not differ between groups. However, children with ASD did show increased no-shift trials in the overlap condition, as well as reduced disengagement efficiency compared to their TD peers. These results provide further support for disengagement impairments in ASD, and suggest that these deficits include disengaging from and shifting to unimodal auditory information.

Brief Report: Cross-Modal Capture: Preliminary Evidence of Inefficient Filtering in Children with Autism Spectrum Disorder / B. KEEHN in Journal of Autism and Developmental Disorders, 49-1 (January 2019)

TOWNSEND, Auteur Article en page(s) : p.385-390 Langues : Anglais (eng) Mots-clés : Attention  Autism  Cross-modal  Distractor inhibition  Filter Index. décimale : PER Périodiques Résumé : This study investigates how task-irrelevant auditory information is processed in children with autism spectrum disorder (ASD). Eighteen children with ASD and 19 age- and IQ-matched typically developing (TD) children were presented with semantically-congruent and incongruent picture-sound pairs, and in separate tasks were instructed to attend to only visual or both audio-visual sensory channels. Preliminary results showed that when required to attend to both modalities, both groups were equally slowed for semantically-incongruent compared to congruent pairs. However, when asked to attend to only visual information, children with ASD were disproportionally slowed by incongruent auditory information, suggesting that they may have more difficulty filtering task-irrelevant cross-modal information. Correlational analyses showed that this inefficient cross-modal attentional filtering was related to greater sociocommunicative impairment.
