Behavioral and cardiac responses to emotional stroop in adults with autism spectrum disorders: influence of medication / Karen J. MATHEWSON in Autism Research, 4-2 (April 2011)  

Public ISBD [article]  inAutism Research > 4-2 (April 2011) . - p.98-108 Titre : Behavioral and cardiac responses to emotional stroop in adults with autism spectrum disorders: influence of medication Type de document : texte imprimé Auteurs : Karen J.

SANTESSO, Auteur ; Sidney SEGALOWITZ, Auteur ; Louis A. SCHMIDT, Auteur Année de publication : 2011 Article en page(s) : p.98-108 Langues : Anglais (eng) Mots-clés : autism spectrum disorders (ASD)  heart period  respiratory sinus arrhythmia (RSA)  Stroop task Index. décimale : PER Périodiques Résumé : Researchers have recently hypothesized that autism spectrum disorders (ASD) may be partly characterized by physiological over-arousal. One way to assess physiological arousal is through autonomic measures. Here heart period (HP) and parasympathetic activity measured by respiratory sinus arrhythmia (RSA) were examined in adults with ASD and matched controls at rest and during performance of an emotional Stroop task. Resting HP and RSA were lower in adults with ASD than in matched controls, consistent with hypothesized over-arousal in ASD. However, dividing the ASD group on the basis of antipsychotic medication usage revealed that group differences in autonomic arousal may be related to the effects of these medications or their correlates. Autonomic adjustments for Stroop performance were comparable across groups, but in the control group, larger RSA reductions were correlated with faster responding (i.e., better performance). This relation was reversed in the unmedicated ASD group and absent in the medicated ASD group. Findings highlight the importance of considering medication status in the recently burgeoning area of psychophysiological studies of autism.

Cortical Serotonin Type-2 Receptor Density in Parents of Children with Autism Spectrum Disorders / Jeremy GOLDBERG in Journal of Autism and Developmental Disorders, 39-1 (January 2009)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-1 (January 2009) . - p.97-104 Titre : Cortical Serotonin Type-2 Receptor Density in Parents of Children with Autism Spectrum Disorders Type de document : texte imprimé Auteurs : Jeremy GOLDBERG, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Peter SZATMARI, Auteur ; George M.

The 5-HT2 binding potentials (BPs) were calculated by ratioing [18F]setoperone intensity in regions of interest (ROI) to cerebellar intensity. Cortical 5-HT2 BPs were significantly lower in parents compared to controls and platelet 5-HT levels were significantly negatively correlated with cortical 5-HT2 BP in parents. Lower cortical 5-HT2 receptor density in parents of children with ASD is consistent with reports of diminished 5-HT2 expression and functioning in individuals with ASD. Further research should examine the relationship of reduced 5-HT2 receptor expression to underlying causation and to clinical and neurochemical correlates of autistic behavior.

Eye Tracking Effort Expenditure and Autonomic Arousal to Social and Circumscribed Interest Stimuli in Autism Spectrum Disorder / J. M. TRAYNOR in Journal of Autism and Developmental Disorders, 49-5 (May 2019)

The present study used eye tracking and a behavioural measure to index effort expenditure, arousal, and attention, during viewing of images depicting social scenes and subject-specific circumscribed interests in a group of 10 adults with ASD (mean age 25.4 years) and 19 typically-developing controls (mean age 20.7 years) Split-plot and one-way repeated measures ANOVAs were used to explore results. A significant difference between the ASD and control group was found in the amount of effort expended to view social and circumscribed images. The ASD group also displayed significant differences in pupillary response to social and circumscribed images, indicative of changes in autonomic arousal. Overall, the results support the social motivation hypothesis in ASD (Chevallier et al., Trends Cogn Sci 16(4):231-239, 2012) and suggest a role for autonomic arousal in the ASD symptom dyad.

Frontal EEG asymmetry moderates the relation between borderline personality disorder features and feelings of social rejection in adolescents / Victoria E. STEAD in Development and Psychopathology, 35-2 (May 2023)

VAN LIESHOUT, Auteur ; Khrista BOYLAN, Auteur Article en page(s) : p.876-890 Langues : Anglais (eng) Mots-clés : adolescents  BPD  frontal EEG asymmetry  social rejection Index. décimale : PER Périodiques Résumé : Although associations among borderline personality disorder (BPD), social rejection, and frontal EEG alpha asymmetry scores (FAA, a neural correlate of emotion regulation and approach-withdrawal motivations) have been explored in different studies, relatively little work has examined these relations during adolescence in the same study. We examined whether FAA moderated the relation between BPD features and rejection sensitivity following a validated social exclusion paradigm, Cyberball. A mixed, clinical-community sample of 64 adolescents (females = 62.5%; Mage = 14.45 years; SD = 1.6; range = 11-17 years) completed psychodiagnostic interviews and a self-report measure of BPD (Time 1). Approximately two weeks later (Time 2), participants completed a resting EEG recording followed by Cyberball. FAA moderated the relation between BPD features and overall feelings of rejection following Cyberball: individuals with greater relative left FAA had the highest and lowest feelings of social rejection depending on whether they had high and low BPD feature scores, respectively. Results remained after controlling for age, sex, gender, depression, and BPD diagnosis. These results suggest that FAA may moderate the relation between BPD features and social rejection, and that left frontal brain activity at rest may be differentially associated with those feelings in BPD. Findings are discussed in terms of the link between left frontal brain activity in the regulation and dysregulation of social approach behaviors, characteristic of BPD.
