The group with ASD was more impaired on all scales of the Vineland than DD peers. When 18 ASD/DD pairs very closely matched on age, verbal and nonverbal development were selected, differences were found only on Vineland Receptive Communication and Daily Living. Correlation analyses to explore connection of these areas of difference with cognition and autistic symptoms suggested that Vineland Daily Living scores were significantly correlated with nonverbal ability and with ADOS total algorithm scores. Vineland Receptive Communication scores correlated significantly only with ADOS total algorithms. The clinical implications of these findings are discussed.

Attend Less, Fear More: Elevated Distress to Social Threat in Toddlers With Autism Spectrum Disorder / Suzanne L. MACARI in Autism Research, 14-5 (May 2021)

Attention to audiovisual speech does not facilitate language acquisition in infants with familial history of autism / Katarzyna CHAWARSKA in Journal of Child Psychology and Psychiatry, 63-12 (December 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-12 (December 2022) . - p.1466-1476 Titre : Attention to audiovisual speech does not facilitate language acquisition in infants with familial history of autism Type de document : Texte imprimé et/ou numérique Auteurs : Katarzyna CHAWARSKA, Auteur ; David LEWKOWICZ, Auteur ; Hannah FEINER, Auteur ; Suzanne MACARI, Auteur ; Angelina VERNETTI, Auteur Article en page(s) : p.1466-1476 Langues : Anglais (eng) Mots-clés : Infant  Child  Humans  Speech  Autistic Disorder  Genetic Predisposition to Disease  Language Development  Language Development Disorders  Autism Spectrum Disorder  Infancy  attention  audiovisual speech  autism  eye-tracking Index. décimale : PER Périodiques Résumé : BACKGROUND: Due to familial liability, siblings of children with ASD exhibit elevated risk for language delays. The processes contributing to language delays in this population remain unclear. METHODS: Considering well-established links between attention to dynamic audiovisual cues inherent in a speaker's face and speech processing, we investigated if attention to a speaker's face and mouth differs in 12-month-old infants at high familial risk for ASD but without ASD diagnosis (hr-sib; n=91) and in infants at low familial risk (lr-sib; n=62) for ASD and whether attention at 12 months predicts language outcomes at 18 months. RESULTS: At 12 months, hr-sib and lr-sib infants did not differ in attention to face (p = .14), mouth preference (p = .30), or in receptive and expressive language scores (p = .36, p = .33). At 18 months, the hr-sib infants had lower receptive (p = .01) but not expressive (p = .84) language scores than the lr-sib infants. In the lr-sib infants, greater attention to the face (p = .022) and a mouth preference (p = .025) contributed to better language outcomes at 18 months. In the hr-sib infants, neither attention to the face nor a mouth preference was associated with language outcomes at 18 months. CONCLUSIONS: Unlike low-risk infants, high-risk infants do not appear to benefit from audiovisual prosodic and speech cues in the service of language acquisition despite intact attention to these cues. We propose that impaired processing of audiovisual cues may constitute the link between genetic risk factors and poor language outcomes observed across the autism risk spectrum and may represent a promising endophenotype in autism.

Atypical Emotional Electrodermal Activity in Toddlers with Autism Spectrum Disorder / Angelina VERNETTI in Autism Research, 13-9 (September 2020)  

Public ISBD [article]  inAutism Research > 13-9 (September 2020) . - p.1476-1488 Titre : Atypical Emotional Electrodermal Activity in Toddlers with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Angelina VERNETTI, Auteur ; Frederick SHIC, Auteur ; Laura BOCCANFUSO, Auteur ; Suzanne MACARI, Auteur ; Finola KANE-GRADE, Auteur ; Anna MILGRAMM, Auteur ; Emily HILTON, Auteur ; Perrine HEYMANN, Auteur ; Matthew S GOODWIN, Auteur ; Katarzyna CHAWARSKA, Auteur Article en page(s) : p.1476-1488 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Past studies in autism spectrum disorder (ASD) indicate atypical peripheral physiological arousal. However, the conditions under which these atypicalities arise and their link with behavioral emotional expressions and core ASD symptoms remain uncertain. Given the importance of physiological arousal in affective, learning, and cognitive processes, the current study examined changes in skin conductance level (?SCL) in 41 toddlers with ASD (mean age: 22.7?months, SD: 2.9) and 32 age-matched toddlers with typical development (TD) (mean age: 21.6 months, SD: 3.6) in response to probes designed to induce anger, joy, and fear emotions. The magnitude of ?SCL was comparable during anger (P =?0.206, d =?0.30) and joy (P =?0.996, d =?0.01) conditions, but significantly lower during the fear condition (P =?0.001, d =?0.83) in toddlers with ASD compared to TD peers. In the combined samples, ?SCL positively correlated with intensity of behavioral emotional expressivity during the anger (r[71] = 0.36, P =?0.002) and fear (r[68] = 0.32, P =?0.007) conditions, but not in the joy (r[69] = ?0.15, P =?0.226) condition. Finally, ?SCL did not associate with autism symptom severity in any emotion-eliciting condition in the ASD group. Toddlers with ASD displayed attenuated ?SCL to situations aimed at eliciting fear, which may forecast the emergence of highly prevalent internalizing and externalizing problems in this population. The study putatively identifies ?SCL as a dimension not associated with severity of autism but with behavioral responses in negatively emotionally challenging events and provides support for the feasibility, validity, and incipient utility of examining ?SCL in response to emotional challenges in very young children. Lay Summary Physiological arousal was measured in toddlers with autism exposed to frustrating, pleasant, and threatening tasks. Compared to typically developing peers, toddlers with autism showed comparable arousal responses to frustrating and pleasant events, but lower responses to threatening events. Importantly, physiological arousal and behavioral expressions were aligned during frustrating and threatening events, inviting exploration of physiological arousal to measure responses to emotional challenges. Furthermore, this study advances the understanding of precursors to emotional and behavioral problems common in older children with autism.
