Altered pre-ejection period response to social evaluative threat in adolescents with autism spectrum disorder / E. Kale EDMISTON in Research in Autism Spectrum Disorders, 36 (April 2017)
[article]
Titre : Altered pre-ejection period response to social evaluative threat in adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : E. Kale EDMISTON, Auteur ; Rachael A. MUSCATELLO, Auteur ; Blythe A. CORBETT, Auteur Article en page(s) : p.57-65 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Pre-ejection period Social evaluative threat Adolescence Social behavior Index. décimale : PER Périodiques Résumé : The autonomic nervous system (ANS) is involved in regulating social behavior; Autism Spectrum Disorder (ASD) is characterized by alterations in social behavior and reduced physiological response to threat. We hypothesized that adolescents with ASD would show reduced ANS response to social threat. Methods Eighteen males with ASD and thirteen males with typical development (TD), ages 12 to 17, completed a social threat paradigm while wearing an impedance cardiography apparatus. We calculated pre-ejection period (PEP) and tested for between-group differences in PEP response to social threat. We also conducted correlation analyses between PEP change scores and clinical symptom scales. Results There was an effect of diagnosis on change in PEP from baseline to the onset of social threat (F = 7.60, p = 0.01), with greater changes in PEP in TD compared to ASD. PEP change score and the Social Communication Questionnaire (r = 0.634, p = 0.005) and the ADHD Problems Subscale of the Child Behavior Checklist (r = 0.568, p = 0.014) were correlated. These findings suggest reduced arousal in response to social threat in ASD, with preliminary evidence that reduced sympathetic activation is associated with increased social behavior symptoms.

Titre : Callous-unemotional traits and fearlessness: A cardiovascular psychophysiological perspective in two adolescent samples using virtual reality Type de document : Texte imprimé et/ou numérique Auteurs : Nicholas D. THOMSON, Auteur ; Steven M. GILLESPIE, Auteur ; Luna C. M. CENTIFANTI, Auteur Article en page(s) : p.803-815 Langues : Anglais (eng) Mots-clés : Callous-unemotional traits fearlessness pre-ejection period respiratory sinus arrhythmia Index. décimale : PER Périodiques Résumé : There has been a longstanding debate about the link between callous-unemotional traits and fearlessness. However, biological evidence for a relationship in adolescents is lacking. Using two adolescent samples, we measured emotional reactivity and cardiac measures of sympathetic (pre-ejection period) and parasympathetic (respiratory sinus arrhythmia) reactivity during 3D TV and virtual reality fear induction. Study 1 included 62 community adolescents from a stratified sample. Study 2 included 60 adolescents from Emotional and Behavioral Difficulties schools. Results were consistent across both studies. Adolescents with high callous-unemotional traits showed coactivation of the sympathetic and parasympathetic nervous system. Consistent with these results, youths with callous-unemotional traits self-reported that they felt more in control after the fear induction. Thus, in both samples, youth with callous-unemotional traits displayed a physiological and emotional profile suggesting they maintained control during fear induction. Therefore, it is proposed here that a shift in thinking of youth with callous-unemotional traits as fearless to youth with callous-unemotional traits are better able to manage fearful situations, may be more appropriate.
