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)

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.

Examining the relationship between face processing and social interaction behavior in children with and without autism spectrum disorder / Blythe A. CORBETT in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 6-1 (December 2014) . - p.35 Titre : Examining the relationship between face processing and social interaction behavior in children with and without autism spectrum disorder Type de document : texte imprimé Auteurs : Blythe A. CORBETT, Auteur ; Cassandra R. NEWSOM, Auteur ; Alexandra P. KEY, Auteur ; Lydia R. QUALLS, Auteur ; E. Kale EDMISTON, Auteur Article en page(s) : p.35 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Ecological validity  Face memory  Neuropsychology  Play Index. décimale : PER Périodiques Résumé : BACKGROUND: Children with autism spectrum disorder (ASD) show impairment in reciprocal social communication, which includes deficits in social cognition and behavior. Since social cognition and social behavior are considered to be interdependent, it is valuable to examine social processes on multiple levels of analysis. Neuropsychological measures of face processing often reveal deficits in social cognition in ASD including the ability to identify and remember facial information. However, the extent to which neuropsychological measures are associated with or predictive of real-world social behavior is unclear. METHODS: The study investigated 66 children (ASD 34, typically developing (TD) 32) using neuropsychological measures of face processing (identity, affect, and memory). Children also participated in a peer interaction paradigm, which allowed observation and coding of natural social interaction behaviors during play with peers (e.g., Self-Play, Cooperative Play, Verbal Bout). ANCOVA, regression, and correlation models analyzed between-group differences, the ability of neuropsychological measures to predict social behavior, and the strength of the associations. RESULTS: Between-group differences were shown on Memory for Faces Delayed and the peer interaction variables Self-Play and Verbal Bout. Regression models indicated that Memory for Faces Delayed predicted the amount of Self-Play, Equipment use alone, and Cooperative Play with peers on the playground. Autism symptomology only predicted verbal exchange with peers. CONCLUSIONS: Face memory strongly predicts relevant social engagement patterns in both children with and without ASD. Impairment in facial memory is associated with reduced 'real-world' social interaction and more self-play, whereas higher performance in face memory predicts more cooperative play. Results highlight the strong connection between face memory and reciprocal social interaction, suggesting that improvement in one may benefit the other.

Gender diversity in autistic and neurotypical youth over adolescence and puberty: A longitudinal study / Rachael A. MUSCATELLO ; Melissa CYPERSKI ; Eleonora SADIKOVA ; E. Kale EDMISTON ; Trey MCGONIGLE ; Rachel CALVOSA ; Simon VANDEKAR in Autism Research, 17-7 (July 2024)

Adolescence is a critical period for the consolidation of gender identity, yet the extent to which the experience of gender diversity is stable over adolescence and puberty in autistic youth is poorly understood. The aim of the study was to examine the consistency of gender diversity using the gender diversity screening questionnaire for self- and parent-report of youth (GDSQ-S, GDSQ-P) over a four-year longitudinal study of pubertal development in youth with ASD (N = 140, 36 assigned-female-at birth (AFAB)) and typical development (TD, N = 104, 58 assigned-male-at-birth [AMAB]) and their parents. The extent to which diagnosis (ASD vs. TD), assigned sex (AFAB vs. AMAB) and developmental level (age, puberty) predict GDSQ trajectory over time was explored. There was a significant diagnosis by sex-assigned-at-birth by age interaction for GDSQ-S Gender Diversity, p = 0.002, showing higher scores in autistic AFAB youth over adolescence, and TD AFAB showing initially lower, then increasing levels over adolescence. For GDSQ-P, Gender Incongruence was significantly different between the groups, p = 0.032, showing higher incongruence for autistic AFAB around age 10, decreasing between age 12-14 before increasing again, while TD AFAB evidence the inverse trend. AMAB trends were stable. The significant diagnostic, developmental and sex-based differences indicate AFAB youth experience greater gender diversity that evolves over development. Findings suggest gender identity formation is nuanced and may be influenced by pubertal progression, hormonal patterns, and psychosocial factors. Results underscore the need for enhanced understanding of the unique, dynamic profiles of females-assigned-at-birth.

Physiological Response to Social Evaluative Threat in Adolescents with Autism Spectrum Disorder / E. Kale EDMISTON in Journal of Autism and Developmental Disorders, 46-9 (September 2016)

Bivariate correlations also showed a significant relationship between parent reports of social problems and RSA response to the TSST (r = −0.586).

Salivary cortisol and behavioral response to social evaluative threat in adolescents with autism spectrum disorder / E. Kale EDMISTON in Autism Research, 10-2 (February 2017)  

Public ISBD [article]  inAutism Research > 10-2 (February 2017) . - p.346-358 Titre : Salivary cortisol and behavioral response to social evaluative threat in adolescents with autism spectrum disorder Type de document : texte imprimé Auteurs : E. Kale EDMISTON, Auteur ; Scott D. BLAIN, Auteur ; Blythe A. CORBETT, Auteur Article en page(s) : p.346-358 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  adolescence  cortisol  HPA axis  displacement behavior  social evaluative threat Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social behavior. One possible explanation for social communication deficits in ASD could be differences in biological systems that support responses to environmental stimuli. If so, it is unclear if differences in the arousal response to social stimuli in ASD are due to reduced interest in social information, or to an increased stress response. The hypothalamic pituitary adrenal axis facilitates arousal and the stress response to sensory input, including social stimuli. Previous research shows blunted cortisol response to social evaluative threat in children with ASD. The majority of prior work has focused on children with ASD, but adolescents with ASD are understudied. The adolescent period is of interest, as this developmental epoch is associated with increased salience of social evaluative threat in typically developing (TD) populations. In this study, we employed the Trier Social Stress Test (TSST), a laboratory paradigm that involves exposure to social evaluative threat, to study the cortisol and behavioral response to social evaluative threat in ASD and TD adolescents. Salivary cortisol data were collected at six time points before and after the TSST. Behavioral data were collected using video recordings of the TSST, which were then operationalized and coded. Paired sample t-tests were used to calculate within-group cortisol response to the TSST. Cortisol significantly increased in response to the TSST in the TD group but not the ASD group. The TD group showed a trend for more self-soothing behaviors during the stressor than the ASD group. The lack of a cortisol response to the TSST in the ASD group suggests that the TSST is not interpreted as stressful or salient for ASD adolescents.
