According to the hypervigilance-avoidance hypothesis, AD patients show hypervigilance to threat cues at early stages of processing but avoid threat cues at later stages of processing. Consistently, adults with AD show enhanced neurophysiological responses to threat in early time windows and reduced responses to threat in late time windows. The presence of such a hypervigilance-avoidance effect and its underlying neural sources remain to be determined in clinically anxious children. Methods Twenty-three children diagnosed with an AD and 23 healthy control children aged 8–14 years saw faces with angry and neutral expressions while whole-head magnetoencephalography (MEG) was recorded. Neural sources were estimated based on L2-Minimum Norm inverse source modeling and analyzed in early, midlatency, and late time windows. Results In visual cortical regions, early threat processing was relatively enhanced in patients compared to controls, whereas this relation was inverted in a late interval. Consistent with the idea of affective regulation, the right dorsolateral prefrontal cortex revealed relatively reduced inhibition of early threat processing but revealed enhanced inhibition at a late interval in patients. Both visual-sensory and prefrontal effects were correlated with individual trait anxiety. Conclusions These results support the hypothesis of early sensory hypervigilance followed by later avoidance of threat in anxiety disordered children, presumably modulated by early reduced and later enhanced prefrontal inhibition. This neuronal hypervigilance-avoidance pattern unfolds gradually with increasing trait anxiety, reflecting a progressively biased allocation of attention to threat.

Maternal emotion dysregulation is related to heightened mother–infant synchrony of facial affect / Annett LOTZIN in Development and Psychopathology, 28-2 (May 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-2 (May 2016) . - p.327-339 Titre : Maternal emotion dysregulation is related to heightened mother–infant synchrony of facial affect Type de document : Texte imprimé et/ou numérique Auteurs : Annett LOTZIN, Auteur ; Julia SCHIBORR, Auteur ; Claus BARKMANN, Auteur ; Georg ROMER, Auteur ; Brigitte RAMSAUER, Auteur Article en page(s) : p.327-339 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A heightened synchrony between the mother's and infant's facial affect predicts adverse infant development. We know that maternal psychopathology is related to mother–infant facial affect synchrony, but it is unclear how maternal psychopathology is transmitted to mother–infant synchrony. One pathway might be maternal emotion dysregulation. We examined (a) whether maternal emotion dysregulation is positively related to facial affect synchrony and (b) whether maternal emotion dysregulation mediates the effect of maternal psychopathology on mother–infant facial affect synchrony. We observed 68 mothers with mood disorders and their 4- to 9-month-old infants in the Still-Face paradigm during two play interactions. The mother's and infant's facial affect were rated from high negative to high positive, and the degree of synchrony between the mother's and infant's facial affect was computed with a time-series analysis. Emotion dysregulation was measured with the Difficulties in Emotion Regulation Scale, and psychopathology was assessed with the Symptom Checklist–90–Revised. Higher maternal emotion dysregulation was significantly associated with higher facial affect synchrony; emotion dysregulation fully mediated the effect of maternal psychopathology on facial affect synchrony. Our findings demonstrate that maternal emotion dysregulation rather than maternal psychopathology per se places mothers and infants at risk for heightened facial affect synchrony.
