Better fear conditioning is associated with reduced symptom severity in autism spectrum disorders / Mikle SOUTH in Autism Research, 4-6 (December 2011)

The handful of psychophysiological studies examining amygdala function in ASD using classical fear conditioning paradigms have yielded discordant results. We recorded skin conductance response (SCR) during a simple discrimination conditioning task in 30 children and adolescents (ages 8–18) diagnosed with high-functioning ASD and 30 age- and IQ-matched, typically developing controls. SCR response in the ASD group was uniquely and positively associated with social anxiety; and negatively correlated with autism symptom severity, in particular with social functioning. Fear conditioning studies have tremendous potential to aid understanding regarding the amygdale's role in the varied symptom profile of ASD. Our data demonstrate that such studies require careful attention to task-specific factors, including task complexity; and also to contributions of dimensional, within-group factors that contribute to ASD heterogeneity.

Blunted feedback processing during risky decision making in adolescents with a parental history of substance use disorders / Anja S. EUSER in Development and Psychopathology, 25-4 (November 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-4 (November 2013) . - p.1119-1136 Titre : Blunted feedback processing during risky decision making in adolescents with a parental history of substance use disorders Type de document : Texte imprimé et/ou numérique Auteurs : Anja S. EUSER, Auteur ; Kirstin GREAVES-LORD, Auteur ; Michael J. CROWLEY, Auteur ; Brittany E. EVANS, Auteur ; Anja C. HUIZINK, Auteur ; Ingmar H. A. FRANKEN, Auteur Article en page(s) : p.1119-1136 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Risky decision making, a hallmark phenotype of substance use disorders (SUD), is thought to be associated with deficient feedback processing. Whether these aberrations are present prior to SUD onset or reflect merely a consequence of chronic substance use on the brain remains unclear. The present study investigated whether blunted feedback processing during risky decision making reflects a biological predisposition to SUD. We assessed event-related potentials elicited by positive and negative feedback during performance of a modified version of the Balloon Analogue Risk Task (BART) among high-risk adolescents with a parental history of SUD (HR; n = 61) and normal-risk controls (NR; n = 91). HR males made significantly more risky and faster decisions during the BART than did NR controls. Moreover, HR adolescents showed significantly reduced P300 amplitudes in response to both positive and negative feedback as compared to NR controls. These differences were not secondary to prolonged substance use exposure. Results are discussed in terms of feedback-specific processes. Reduced P300 amplitudes in the BART may reflect poor processing of feedback at the level of overall salience, which may keep people from effectively predicting the probability of future gains and losses. Though conclusions are tentative, blunted feedback processing during risky decision making may represent a promising endophenotypic vulnerability marker for SUD.

Commentary: The importance of exploring dose-dependent, subtype-specific, and age-related effects of maltreatment on the HPA axis and the mediating link to psychopathology. A response to Fisher (2017) / Lars O. WHITE in Journal of Child Psychology and Psychiatry, 58-9 (September 2017)

We agree that our results mesh well with previous work documenting hypocortisolism among youth who experienced early adversity, especially neglect. Moreover, as also perceptively noted by Dr. Fisher, our cross-sectional data provide support for the notion that hypocortisolism is not simply a transient phenomenon, but, rather, a persistent pattern characterizing maltreated youth. Specifically, the consistency of the between group effect (from age 9.69 onwards) on a multimonth index of cumulative cortisol and the dose-dependent gradient of cortisol secretion within the maltreated group, which was related to the number of subtypes and the length of exposure to maltreatment, lend weight to this view.

Emotional maltreatment and neglect impact neural activation upon exclusion in early and mid-adolescence: An event-related fMRI study / Charlotte C. SCHULZ in Development and Psychopathology, 34-2 (May 2022)

Yet, few neuroimaging studies in adolescents use peer interaction paradigms to parse neural correlates of distinct maltreatment exposures. This fMRI study examines effects of abuse, neglect, and emotional maltreatment (EM) among 98 youth (n = 58 maltreated; n = 40 matched controls) using an event-related Cyberball paradigm affording assessment of both social exclusion and inclusion across early and mid-adolescence (?13.5 years, n = 50; >13.5 years, n = 48). Younger adolescents showed increased activation to social exclusion versus inclusion in regions implicated in mentalizing (e.g., superior temporal gyrus). Individual exposure-specific analyses suggested that neglect and EM coincided with less reduction of activation to social exclusion relative to inclusion in the dorsal anterior cingulate cortex/pre-supplementary motor area (dACC/pre-SMA) among younger versus older adolescents. Integrative follow-up analyses showed that EM accounted for this dACC/pre-SMA activation pattern over and above other exposures. Moreover, age-independent results within respective exposure groups revealed that greater magnitude of neglect predicted blunted exclusion-related activity in the parahippocampal gyrus, while EM predicted increased activation to social exclusion in the precuneus/posterior cingulate cortex.

Failure is Not an Option: Risk-Taking is Moderated by Anxiety and Also by Cognitive Ability in Children and Adolescents Diagnosed with an Autism Spectrum Disorder / Mikle SOUTH in Journal of Autism and Developmental Disorders, 41-1 (January 2011)

In 40 children and adolescents diagnosed with ASD and 37 IQ—and age-matched comparison participants (the TYP group), we found no differences in summary measures on an experimental risk-taking task. However, anxiety and IQ predicted risk-taking only in the ASD group. Risk-taking was correlated with behavioral inhibition in the ASD group and behavioral activation in the TYP group. We suggest that performance on the task was motivated by fear of failure in the ASD group and by sensitivity to reward in the TYP group. Behavioral markers of anxiety and cognitive ability may improve conceptualization of heterogeneity in ASD.
