We examined behavioral and physiological responses during an emotion-evoking task designed to elicit emotional states in infants. Infants at an increased likelihood for ASD (IL; have an older sibling with ASD; 96 not classified; 29 classified with ASD at age two) and low likelihood (LL; no family history of ASD; n = 61) completed the task at 6, 12, and 18 months. The main findings were (1) the IL-ASD group displayed higher levels of negative affect during toy removal and negative tasks compared to the IL non-ASD and LL groups, respectively, (2) the IL-ASD group spent more time looking at the baseline task compared to the other two groups, and (3) the IL-ASD group showed a greater increase in heart rate from baseline during the toy removal and negative tasks compared to the LL group. These results suggest that IL children who are classified as ASD at 24 months show differences in affect, gaze, and heart rate during an emotion-evoking task, with potential implications for understanding mechanisms related to emerging ASD.

Comparative strengths and challenges on face-to-face and computer-based attention tasks in autistic and neurotypical toddlers / Lori-Ann R. SACREY in Autism Research, 16-8 (August 2023)  

Public ISBD [article]  inAutism Research > 16-8 (August 2023) . - p.1501-1511 Titre : Comparative strengths and challenges on face-to-face and computer-based attention tasks in autistic and neurotypical toddlers Type de document : Texte imprimé et/ou numérique Auteurs : Lori-Ann R. SACREY, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Yomna ELSHAMY, Auteur ; Isabel M. SMITH, Auteur ; Jessica A. BRIAN, Auteur ; Sam WASS, Auteur Article en page(s) : p.1501-1511 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract The objectives were to compare patterns of visual attention in toddlers diagnosed with autism spectrum disorder (ASD) as compared to their sex- and age-matched neurotypical (NT) peers. Participants included 23 toddlers with ASD and 19 NT toddlers (mean age: 25.52 versus 25.21?months, respectively) assessed using computerized tasks to measure sustained attention, disengaging attention, and cognitive control, as well as an in-person task to assess joint attention. Toddlers in the ASD group showed increased looking durations on the sustained attention task, as well as reduced frequencies of responding to and initiating joint attention compared to NT peers, but showed no differences on tasks of disengaging attention and cognitive control. The results suggest that toddlers with ASD have attentional strengths that may provide a foundation for building attention, communicative, and ultimately, academic skills.
