Conflict adaptation and congruency sequence effects to social–emotional stimuli in individuals with autism spectrum disorders / Whitney WORSHAM in Autism, 19-8 (November 2015)  

Public ISBD [article]  inAutism > 19-8 (November 2015) . - p.897-905 Titre : Conflict adaptation and congruency sequence effects to social–emotional stimuli in individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Whitney WORSHAM, Auteur ; Whitney E. GRAY, Auteur ; Michael J. LARSON, Auteur ; Mikle SOUTH, Auteur Article en page(s) : p.897-905 Langues : Anglais (eng) Mots-clés : autism  cognitive control  conflict adaptation  social cognition Index. décimale : PER Périodiques Résumé : Background: The modification of performance following conflict can be measured using conflict adaptation tasks thought to measure the change in the allocation of cognitive resources in order to reduce conflict interference and improve performance. While previous studies have suggested atypical processing during nonsocial cognitive control tasks, conflict adaptation (i.e. congruency sequence effects) for social–emotional stimuli have not been previously studied in autism spectrum disorder.Methods: A total of 32 participants diagnosed with autism spectrum disorder and 27 typically developing matched controls completed an emotional Stroop conflict task that required the classification of facial affect while simultaneously ignoring an overlaid affective word.Results: Both groups showed behavioral evidence for emotional conflict adaptation based on response times and accuracy rates. However, the autism spectrum disorder group demonstrated a speed-accuracy trade-off manifested through significantly faster response times and decreased accuracy rates on trials containing conflict between the emotional face and the overlaid emotional word.Conclusion: Reduced selective attention toward socially relevant information may bias individuals with autism spectrum disorder toward more rapid processing and decision making even when conflict is present. Nonetheless, the loss of important information from the social stimuli reduces decision-making accuracy, negatively affecting the ability to adapt both cognitively and emotionally when conflict arises.

ASD case and PNMS exposure status of index offspring were determined through linkage with autism registries and birth certificate records. ASD case (N = 53) and control (N = 19) groups were enriched for PNMS exposure. Higher estradiol and lower sex hormone binding globulin (SHBG) were significantly associated with increased ASD risk.

Sex-specific and sex-independent steroid-related biomarkers in early second trimester maternal serum associated with autism / Whitney WORSHAM ; Scott SULLIVAN ; M. Sean ESPLIN ; Paul BURGHARDT ; Alison FRASER ; Amanda V. BAKIAN in Molecular Autism, 14 (2023)  

Public ISBD [article]  inMolecular Autism > 14 (2023) . - 30 p. Titre : Sex-specific and sex-independent steroid-related biomarkers in early second trimester maternal serum associated with autism Type de document : Texte imprimé et/ou numérique Auteurs : Whitney WORSHAM, Auteur ; Scott SULLIVAN, Auteur ; M. Sean ESPLIN, Auteur ; Paul BURGHARDT, Auteur ; Alison FRASER, Auteur ; Amanda V. BAKIAN, Auteur Article en page(s) : 30 p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Prenatal exposure to maternal metabolic conditions associated with inflammation and steroid dysregulation has previously been linked to increased autism risk. Steroid-related maternal serum biomarkers have also provided insight into the in utero steroid environment for offspring who develop autism. OBJECTIVE: This study examines the link between autism among offspring and early second trimester maternal steroid-related serum biomarkers from pregnancies enriched for prenatal metabolic syndrome (PNMS) exposure. STUDY DESIGN: Early second trimester maternal steroid-related serum biomarkers (i.e., estradiol, free testosterone, total testosterone, and sex hormone binding globulin) were compared between pregnancies corresponding to offspring with (N=68) and without (N=68) autism. Multiple logistic regression analyses were stratified by sex and gestational duration. One-way ANCOVA with post hoc tests was performed for groups defined by autism status and PNMS exposure. RESULTS: Increased estradiol was significantly associated with autism only in males (AOR=1.13 per 100 pg/ml, 95% CI 1.01-1.27, p=0.036) and only term pregnancies (AOR=1.17 per 100 pg/ml, 95% CI 1.04-1.32, p=0.010). Autism status was significantly associated with decreased sex hormone binding globulin (AOR=0.65 per 50 nmol/L, 95% CI 0.55-0.78, p<0.001) overall and when stratified by sex and term pregnancy status. The inverse association between sex hormone binding globulin and autism was independent of PNMS exposure. LIMITATIONS: The relative racial and ethnic homogeneity of Utah's population limits the generalizability of study results. Although significant differences by autism status were identified in concentrations of sex hormone binding globulin overall and of estradiol in participant subgroups, differences by PNMS exposure failed to reach statistical significance, which may reflect insufficient statistical power. CONCLUSION: Both elevated maternal serum estradiol in males only and low maternal serum sex hormone binding globulin in both sexes are associated with increased autism risk. Further investigation is merited to identify how steroid, metabolic, and inflammatory processes can interact to influence neurodevelopment in early second trimester.
