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)
[article]
Titre : Attend Less, Fear More: Elevated Distress to Social Threat in Toddlers With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Suzanne L. MACARI, Auteur ; Angelina VERNETTI, Auteur ; Katarzyna CHAWARSKA, Auteur Article en page(s) : p.1025-1036 Langues : Anglais (eng) Mots-clés : attention emotion regulation emotional reactivity social threat Index. décimale : PER Périodiques Résumé : Differential emotional reactivity to social and nonsocial stimuli has been hypothesized but rarely examined empirically in ASD despite its potential importance for development of social motivation, cognition, and comorbid psychopathology. This study examined emotional reactivity, regulation, and attention to social and nonsocial threat in toddlers with ASD (n =?42, M(age) : 22?months) and typically developing (TD) toddlers (n =?22, M(age) : 23?months), and their mutual associations with autism symptom severity. Participants were exposed to social (stranger), nonsocial (mechanical objects), and ambiguous (masks) threats, and their intensity of distress (iDistress), attention to threat (Attention), and presence of emotion regulation (ER) strategies were measured. Autism symptom severity was quantified using the Autism Diagnostic Observation Schedule-2. In response to social threat, toddlers with ASD exhibited elevated iDistress (P 0.038) but lower Attention (P 0.002) and a wider variety of ER strategies (P 0.040) compared to TD controls, though their ER strategies were less likely to be social. However, nonsocial and ambiguous threat elicited lower iDistress in ASD than in TD toddlers (P =?0.012 and P =?0.034, respectively), but comparable Attention and ER strategy use. Autism severity was not associated with iDistress. The study demonstrates elevated emotional salience but diminished attentional salience of social threat in ASD. A failure to attend adequately to social threats may restrict opportunities to appraise their threat value and engender often observed in ASD negative emotional responses to novel social situations. Early atypical emotional reactivity may independently contribute to the shaping of complex autism phenotypes and may be linked with later emerging affective and behavioral symptoms. LAY SUMMARY: Compared to typically developing toddlers, toddlers with ASD show diminished attention yet enhanced distress in response to social threat. Poor attention to potential social threat may limit opportunities to assess its threat value and thus contribute to often observed negative emotional responses to novel social situations. Identifying the precursors of atypical emotional reactivity in infancy and its links with later psychopathology will inform about novel treatment targets and mechanisms of change in the early stages of ASD.

[article]
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.

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.

Titre : Family history of psychiatric conditions and development of siblings of children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Joseph CHANG, Auteur ; Zeyan LIEW, Auteur ; Angelina VERNETTI, Auteur ; Suzanne MACARI, Auteur ; Kelly POWELL, Auteur ; Katarzyna CHAWARSKA, Auteur Article en page(s) : p.1665-1676 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Younger siblings (SIBS) of children with autism exhibit a wide range of clinical and subclinical symptoms including social, cognitive, language, and adaptive functioning delays. Identifying factors linked with this phenotypic heterogeneity is essential for improving understanding of the underlying biology of the heterogenous outcomes and for early identification of the most vulnerable SIBS. Prevalence of neurodevelopmental (NDD) and neuropsychiatric disorders (NPD) is significantly elevated in families of children with autism. It remains unknown, however, if the family history associates with the developmental outcomes among the SIBS. We quantified history of the NDDs and NPDs commonly reported in families of children with autism using a parent interview and assessed autism symptoms, verbal, nonverbal, and adaptive skills in a sample of 229 SIBS. Multiple regression analyses were used to examine links between family history and phenotypic outcomes, whereas controlling for birth year, age, sex, demographics, and parental education. Results suggest that family history of schizophrenia, depression, anxiety, bipolar disorder, and intellectual disability associate robustly with dimensional measures of social affect, verbal and nonverbal IQ, and adaptive functioning in the SIBS. Considering family history of these disorders may improve efforts to predict long-term outcomes in younger siblings of children with autism and inform about familial factors contributing to high phenotypic heterogenetity in this cohort.
