Social behavior and cortisol reactivity in children with fragile X syndrome / David HESSL in Journal of Child Psychology and Psychiatry, 47-6 (June 2006)

Method: Salivary cortisol changes and concurrent anxiety-related behaviors consistent with the behavioral phenotype of FXS were measured in 90 children with the fragile X full mutation and their 90 unaffected siblings during a social challenge task in the home. Results: Boys and girls with FXS demonstrated more gaze aversion, task avoidance, behavioral signs of distress, and poorer vocal quality than the unaffected siblings. Multiple regression analyses showed that after accounting for effects of IQ, gender, age, quality of the home environment, and basal cortisol level, cortisol reactivity to the task was significantly associated with social gaze in children with FXS. The most gaze-aversive children with FXS had cortisol reductions, whereas those with more eye contact demonstrated the most cortisol reactivity. Unaffected siblings demonstrated an opposite pattern in which less eye contact was associated with increased cortisol reactivity. Conclusions: Results of the study suggest a unique relation between abnormal gaze behavior and L-HPA mediated stress reactivity in FXS.

The effect of emotional intensity on responses to joint attention in preschoolers with an autism spectrum disorder / Martina FRANCHINI in Research in Autism Spectrum Disorders, 35 (March 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 35 (March 2017) . - p.13-24 Titre : The effect of emotional intensity on responses to joint attention in preschoolers with an autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Martina FRANCHINI, Auteur ; Bronwyn GLASER, Auteur ; Edouard GENTAZ, Auteur ; Hilary WOOD, Auteur ; Stephan ELIEZ, Auteur ; Marie SCHAER, Auteur Article en page(s) : p.13-24 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Eye-tracking  Response to joint attention (RJA)  Emotional expressions  Gestural pointing Index. décimale : PER Périodiques Résumé : Responding to joint attention (RJA) is reduced in young children with ASD despite being vital to the early development of social communication. For this reason, RJA is a frequent target in early intervention programs. Clinical guidelines suggest that exaggerating facial expressions or gestural pointing may improve RJA in children with autism by clarifying the meaning of the gaze or gesture. In the current study, we investigate the effect of intensity of emotional expression on RJA in preschoolers with ASD. Method Twenty-five preschoolers with ASD and 21 typically developing peers were administered a specifically designed eye-tracking task in which an actor directs attention to a moving object by looking at it with an expression that was either neutral, mildly surprised or intensely surprised. In a supplementary condition, gestural pointing was accompanied by a neutral gaze shift. Results Commensurate with previous studies, children with ASD oriented less to the face of the actor and were less responsive to RJA when compared to their typically developing peers. However, children with autism differed in their response to RJA according to the different task conditions. They demonstrated more frequent responses to RJA when the actor’s facial expression was either intense or supported by gestural pointing. We report initial evidence for the importance of clarifying content cues in order to help preschoolers with autism adhere to receptive joint attention (RJA) opportunities. Our findings inform knowledge about early treatment and attention to emotional expressions in autism and improve our understanding of how early interventions may work to increase RJA in young children with ASD.
