Affective prosody labeling in youths with bipolar disorder or severe mood dysregulation / Christen M. DEVENEY in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.262-270 Titre : Affective prosody labeling in youths with bipolar disorder or severe mood dysregulation Type de document : Texte imprimé et/ou numérique Auteurs : Christen M. DEVENEY, Auteur ; Melissa A. BROTMAN, Auteur ; Ann Marie DECKER, Auteur ; Stephanie S. DANIEL, Auteur ; Ellen LEIBENLUFT, Auteur Année de publication : 2012 Article en page(s) : p.262-270 Langues : Anglais (eng) Mots-clés : Bipolar disorder  emotion recognition Index. décimale : PER Périodiques Résumé : Background:  Accurate identification of nonverbal emotional cues is essential to successful social interactions, yet most research is limited to emotional face expression labeling. Little research focuses on the processing of emotional prosody, or tone of verbal speech, in clinical populations. Methods:  Using the Diagnostic Analysis of Nonverbal Accuracy, the current study examined whether youths with pediatric-onset bipolar disorder (BD) and/or those with chronic and severe irritability (i.e. the severe mood dysregulation phenotype) are impaired in their ability to identify the emotional prosody of a spoken sentence with neutral content. Results:  Youths with severe mood dysregulation (n = 67) performed more poorly than healthy comparison children (n = 57), even when the sample was limited to unmedicated patients. Medicated BD youths (n = 52) exhibited impairment relative to healthy comparison children. No interactions between group and emotion were observed, suggesting that emotional prosody labeling problems may represent a general deficit in chronically irritable youths and in medicated youths with BD. Conclusion:  In concert with previously documented facial emotion labeling deficits, difficulties ascertaining the correct emotional tone of a spoken sentence may contribute to emotion dysregulation in chronically irritable children, and possibly also in youths with BD.

Anxiety symptoms and children's eye gaze during fear learning / Kalina J. MICHALSKA in Journal of Child Psychology and Psychiatry, 58-11 (November 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-11 (November 2017) . - p.1276-1286 Titre : Anxiety symptoms and children's eye gaze during fear learning Type de document : Texte imprimé et/ou numérique Auteurs : Kalina J.

PINE, Auteur Article en page(s) : p.1276-1286 Langues : Anglais (eng) Mots-clés : Eye gaze  face processing  anxiety  conditioning  psychophysiology Index. décimale : PER Périodiques Résumé : Background The eye region of the face is particularly relevant for decoding threat-related signals, such as fear. However, it is unclear if gaze patterns to the eyes can be influenced by fear learning. Previous studies examining gaze patterns in adults find an association between anxiety and eye gaze avoidance, although no studies to date examine how associations between anxiety symptoms and eye-viewing patterns manifest in children. The current study examined the effects of learning and trait anxiety on eye gaze using a face-based fear conditioning task developed for use in children. Methods Participants were 82 youth from a general population sample of twins (aged 9–13 years), exhibiting a range of anxiety symptoms. Participants underwent a fear conditioning paradigm where the conditioned stimuli (CS+) were two neutral faces, one of which was randomly selected to be paired with an aversive scream. Eye tracking, physiological, and subjective data were acquired. Children and parents reported their child's anxiety using the Screen for Child Anxiety Related Emotional Disorders. Results Conditioning influenced eye gaze patterns in that children looked longer and more frequently to the eye region of the CS+ than CS? face; this effect was present only during fear acquisition, not at baseline or extinction. Furthermore, consistent with past work in adults, anxiety symptoms were associated with eye gaze avoidance. Finally, gaze duration to the eye region mediated the effect of anxious traits on self-reported fear during acquisition. Conclusions Anxiety symptoms in children relate to face-viewing strategies deployed in the context of a fear learning experiment. This relationship may inform attempts to understand the relationship between pediatric anxiety symptoms and learning.

Cross-sectional and longitudinal abnormalities in brain structure in children with severe mood dysregulation or bipolar disorder / Nancy E. ADLEMAN in Journal of Child Psychology and Psychiatry, 53-11 (November 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-11 (November 2012) . - p.1149-1156 Titre : Cross-sectional and longitudinal abnormalities in brain structure in children with severe mood dysregulation or bipolar disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nancy E. ADLEMAN, Auteur ; Stephen J. FROMM, Auteur ; Varun RAZDAN, Auteur ; Reilly KAYSER, Auteur ; Daniel P. DICKSTEIN, Auteur ; Melissa A. BROTMAN, Auteur ; Daniel Samuel PINE, Auteur ; Ellen LEIBENLUFT, Auteur Année de publication : 2012 Article en page(s) : p.1149-1156 Langues : Anglais (eng) Mots-clés : Severe mood dysregulation  bipolar disorder  pediatric  longitudinal  neuroimaging  voxel-based morphometry  Trouble de l'humeur Index. décimale : PER Périodiques Résumé : Background:  There is debate as to whether chronic irritability (operationalized as severe mood dysregulation, SMD) is a developmental form of bipolar disorder (BD). Although structural brain abnormalities in BD have been demonstrated, no study compares neuroanatomy among SMD, BD, and healthy volunteers (HV) either cross-sectionally or over time. Furthermore, the developmental trajectories of structural abnormalities in BD or SMD are unknown. This study provides such data in BD, SMD, and HV. Methods:  An optimized, modulated voxel-based morphometry (VBM) analysis was conducted on structural MRI scans from 201 children (78 SMD, 55 BD, and 68 HV). In addition, 92 children (31 SMD, 34 BD, and 27 HV) were rescanned after 2 years (mean interval 1.99 ± 0.94 years), to compare time-related changes among the three groups. Results:  Cross-sectionally, the groups differed in gray matter (GM) volume in presupplementary motor area (pre-SMA), dorsolateral prefrontal cortex (DLPFC), insula, and globus pallidus. The cortical differences were driven mainly by increased GM volume in HV compared with BD and SMD. In globus pallidus, there was increased GM in BD compared with HV and SMD. Longitudinally, group-by-time interactions were evident in two clusters in the superior/inferior parietal lobule (R SPL/IPL) and in the precuneus. In both clusters, the interactions were driven by an abnormal increase in volume in BD. Conclusions:  Cross-sectionally, both BD and SMD are associated with structural abnormalities in frontal cortex, insula, and basal ganglia. Although some of these deficits overlap (insula and DLPFC), others differentiate SMD and BD (pre-SMA and globus pallidus). Abnormal developmental trajectories in lateral parietal cortex and precuneus are present in, and unique to, BD. Because of the high proportion of co-occurring ADHD in the SMD subjects, we could not separate effects of ADHD from those of SMD, and future research including a nonirritable ADHD group must address this issue.

Genetic underpinnings of callous-unemotional traits and emotion recognition in children, adolescents, and emerging adults / A. A. MOORE in Journal of Child Psychology and Psychiatry, 60-6 (June 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-6 (June 2019) . - p.638-645 Titre : Genetic underpinnings of callous-unemotional traits and emotion recognition in children, adolescents, and emerging adults Type de document : Texte imprimé et/ou numérique Auteurs : A.

ROBERSON-NAY, Auteur Article en page(s) : p.638-645 Langues : Anglais (eng) Mots-clés : Callous-unemotional traits  emotion recognition  genetics  psychopathy  twins Index. décimale : PER Périodiques Résumé : BACKGROUND: Callous-Unemotional (CU) and psychopathic traits are consistently associated with impaired recognition of others' emotions, specifically fear and sadness. However, no studies have examined whether the association between CU traits and emotion recognition deficits is due primarily to genetic or environmental factors. METHODS: The current study used data from 607 Caucasian twin pairs (N = 1,214 twins) to examine the phenotypic and genetic relationship between the Inventory of Callous-Unemotional Traits (ICU) and facial emotion recognition assessed via the laboratory-based Facial Expression Labeling Task (FELT). RESULTS: The uncaring/callous dimension of the ICU was significantly associated with impaired recognition of happiness, sadness, fear, surprise, and disgust. The unemotional ICU dimension was significantly associated with improved recognition of surprise and disgust. Total ICU score was significantly associated with impaired recognition of sadness. Significant genetic correlations were found for uncaring/callous traits and distress cue recognition (i.e. fear and sadness). The observed relationship between uncaring/callous traits and deficits in distress cue recognition was accounted for entirely by shared genetic influences. CONCLUSIONS: The results of the current study replicate previous findings demonstrating impaired emotion recognition among youth with elevated CU traits. We extend these findings by replicating them in an epidemiological sample not selected or enriched for pathological levels of CU traits. Furthermore, the current study is the first to investigate the genetic and environmental etiology of CU traits and emotion recognition, and results suggest genetic influences underlie the specific relationship between uncaring/callous traits and distress cue (fear/sadness) recognition in others.

This study examined prevalence, stability, and heritability of tonic irritability, phasic irritability, and a DMDD proxy (pDMDD) based on DSM-5 criteria. METHODS: pDMDD was derived using data from clinical interviews of parents and their twins (N = 1,431 twin pairs), ages 8-17, participating in Waves 1 and 2 of the Virginia Twin Study of Adolescent Behavioral Development. Biometrical modeling was used to compare a common pathway model (CPM) and an independent pathway model (IPM), and heritability estimates were obtained for pDMDD using the symptoms of irritable mood (tonic irritability; DMDD Criterion D), intense temper outbursts (phasic irritability; DMDD Criterion A), and frequent temper outbursts (phasic irritability; DMDD Criterion C). RESULTS: Lifetime prevalence of pDMDD was 7.46%. The stability of DMDD symptoms and the pDMDD phenotype across approximately one year were moderate (.30-.69). A CPM was a better fit to the data than an IPM. Phasic irritability loaded strongly onto the pDMDD latent factor (.89-.96) whereas tonic irritability did not (.28). Genetic influences accounted for approximately 59% of the variance in the latent pDMDD phenotype, with the remaining 41% of the variance due to unique environmental effects. The heritability of tonic irritability (54%) was slightly lower than that of frequent and intense temper (components of phasic irritability; 61% and 63%, respectively). CONCLUSIONS: Compared to tonic irritability, phasic irritability appears to be slightly more stable and heritable, as well as a stronger indicator of the latent factor. Furthermore, environmental experiences appear to play a substantial role in the development of irritability and DMDD, and researchers should seek to elucidate these mechanisms in future work.
