Adults with and without ASD completed a facial emotion recognition task involving stimuli that varied by emotional intensity while electroencephalograms were recorded. Principal components analysis was used to examine P300 and late positive potential (LPP) modulation by emotional intensity. Results indicated that greater ASD symptomatology evinced heightened P300 to high relative to low intensity faces, then heightened LPP to low relative to high intensity faces. Findings suggest that adults with greater ASD symptomatology may demonstrate a lag in engagement in elaborative processing of low intensity faces.

In a recent study, we evaluated a multimethod strategy for assessing anxiety in children with ASD and IDD (Am J Intellect Dev Disabil 118:419-434, 2013). In the present study, we developed treatments for the anxiety and associated problem behavior in these same children. A multiple baseline design was used to evaluate the effectiveness of a multicomponent intervention package, incorporating individualized strategies from Positive Behavior Support and Cognitive Behavioral Therapy. During intervention, all three participants showed substantial decreases in anxiety and problem behavior and significant increases in respiratory sinus arrhythmia in the situations that had previously been identified as anxiety-provoking.

[article]
Titre : Neural reward responsiveness in children who engage in nonsuicidal self-injury: an ERP study Type de document : Texte imprimé et/ou numérique Auteurs : A. TSYPES, Auteur ; M. OWENS, Auteur ; G. HAJCAK, Auteur ; B. E. GIBB, Auteur Article en page(s) : p.1289-1297 Langues : Anglais (eng) Mots-clés : Nonsuicidal self-injury children event-related potential feedback negativity rewards Index. décimale : PER Périodiques Résumé : BACKGROUND: A better understanding of the correlates of nonsuicidal self-injury (NSSI) in children is important for the identification and prevention of future suicide risk. However, although abnormalities in reward responsiveness might constitute one potential transdiagnostic mechanism of risk for NSSI, no studies have examined initial response to reward in children with a history of NSSI. The goal of the present study was to address this important gap in the literature. To objectively assess initial response to reward, we utilized the feedback negativity (FN) event-related potential, a well-established psychophysiological marker of reward responsiveness. METHODS: Participants were 57 children (19 with a history of NSSI and 38 demographically matched controls) between the ages of 7 and 11. Diagnostic interviews were used to assess for current and past DSM-IV mood and anxiety diagnoses and NSSI history. Children also completed a guessing task, during which continuous electroencephalography was recorded. RESULTS: Children with a history of NSSI exhibited significantly more negative DeltaFN (i.e., FN to losses minus FN to gains) than children without NSSI. These findings appeared to be at least partially independent of children's history of psychopathology and current symptoms, suggesting their specificity to NSSI. CONCLUSIONS: These results provide initial evidence for heightened neural initial reward responsiveness to losses versus rewards in children with a history of NSSI. Pending replications and longitudinal studies, the DeltaFN might represent a psychophysiological marker of risk for self-harm.

Additionally, despite evidence that stress and parenting may both influence the development of neural systems underlying reward and threat processing, few studies have brought together these areas of research. The current investigation examined the effect of parenting styles and hurricane-related stress on the development of neural reactivity to reward and threat in children. Approximately 8 months before and 9 months after Hurricane Sandy, 74 children experiencing high and low levels of hurricane-related stress completed tasks that elicited the reward positivity and error-related negativity, event-related potentials indexing sensitivity to reward and threat, respectively. At the post-Hurricane assessment, children completed a self-report questionnaire to measure promotion- and prevention-focused parenting styles. Among children exposed to high levels of hurricane-related stress, lower levels of promotion-focused, but not prevention-focused, parenting were associated with a reduced post-Sandy reward positivity. In addition, in children with high stress exposure, greater prevention-focused, but not promotion-focused, parenting was associated with a larger error-related negativity after Hurricane Sandy. These findings highlight the need to consider contextual variables such as parenting when examining how exposure to stress alters the development of neural reactivity to reward and threat in children.

Titre : Reduced reward responsiveness moderates the effect of maternal depression on depressive symptoms in offspring: evidence across levels of analysis Type de document : Texte imprimé et/ou numérique Auteurs : A. KUJAWA, Auteur ; G. HAJCAK, Auteur ; D. N. KLEIN, Auteur Article en page(s) : p.82-90 Langues : Anglais (eng) Mots-clés : adolescence depression event-related potentials maternal depression resilience reward vulnerability Index. décimale : PER Périodiques Résumé : BACKGROUND: Reduced reward responsiveness (RR) may contribute to depression vulnerability. At the neurophysiological level, RR is reliably and validly assessed using the reward positivity (RewP) event-related potential component. We previously identified a blunted RewP in 9-year-old children at high risk for depression due to maternal depression, but the role of RR in pathways from parental history to the development of depressive symptoms has not been examined. METHODS: At age 9, never-depressed children (N = 369) completed a task in which RewP was measured in response to monetary reward and loss feedback. Parental history of depression was assessed using semistructured interviews, and children reported on their depressive symptoms. At age 12, youth depressive symptoms were reassessed, along with a self-report measure of RR. We tested RR as a moderator of the effects of parental depression on depressive symptoms at age 12, using both neurophysiological and self-report measures and controlling for age 9 symptoms. RESULTS: Main effects of RR and interactions with maternal depression were significant. Maternal depression predicted greater depressive symptoms in youth with blunted and average RewP but was not a significant predictor in youth with an enhanced RewP. A similar pattern was observed for self-reported RR. The two measures of RR were not correlated with each other and accounted for unique variance in symptoms. Interactions between RR and paternal depression were not significant. CONCLUSIONS: Reduced RR, as measured by neurophysiology and self-report, moderates the effects of maternal depression on depressive symptoms in offspring. Assessment of RR along with risk factors such as parental depression may aid in identifying children at greatest risk and enhancing RR could be a potential target for prevention. Results highlight the utility of multimethod approaches for advancing understanding of depression risk.
