Effects of social context information on neural face processing in youth with social anxiety disorder / Anna-Lina RAUSCHENBACH in Journal of Child Psychology and Psychiatry, 67-5 (May 2026)

Cognitive models emphasize the role of altered face processing, and neutral facial expressions may be perceived as threatening. Due to their ambiguous nature, contextual cues may play a particularly important role in interpretation. Methods We presented neutral child faces paired with social context information varying in valence (negative, neutral, positive) while continuous EEG was recorded. Subjective valence ratings and neural responses (P100, N170, and LPP) were assessed in children and adolescents aged 10?15?years with SAD (n?=?53), clinical controls with specific phobias (SP; n?=?41), and healthy controls (HC; n?=?61). Results Overall, context information affected both the subjective and neural responses to neutral faces in all children and adolescents, for example, more negative ratings for negatively contextualized faces. Further, participants with SAD generally rated all faces as more negative compared to HCs. Neurally, they showed lower N170 amplitudes compared to both control groups in response to all neutral faces, independent of the context valence. However, only younger children (aged 10?12?years) with SAD showed higher LPP amplitudes than younger HCs. Conclusions Processing biases seem to be already present in children and adolescents with SAD, both at the subjective and neural level. Social context information influences neutral face processing but is independent of psychopathology. Future studies examining age effects are needed to investigate whether childhood reflects a particularly sensitive period for the development of processing biases.

Restricted autonomic flexibility in children with social phobia / Julian SCHMITZ in Journal of Child Psychology and Psychiatry, 52-11 (November 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-11 (November 2011) . - p.1203-1211 Titre : Restricted autonomic flexibility in children with social phobia Type de document : texte imprimé Auteurs : Julian SCHMITZ, Auteur ; Martina KRAMER, Auteur ; Brunna TUSCHEN-CAFFIER, Auteur ; Nina HEINRICHS, Auteur ; Jens BLECHERT, Auteur Année de publication : 2011 Article en page(s) : p.1203-1211 Langues : Anglais (eng) Mots-clés : Social phobia  children  autonomic flexibility  psychopathology Index. décimale : PER Périodiques Résumé : Background:  Psychophysiological hyperresponsiveness to social-evaluative stress plays a key role in current theories of social phobia (SP). Owing to the early onset of this disorder, the study of children with SP can help to improve etiological models. However, research to date has failed to clarify whether children with SP are physiologically hyperresponsive to stress or not. In addition, the existence of elevated pre-stressor baseline group differences complicates the interpretation of acute stress responses and therefore poses a challenge for this line of research. Drawing on current models of autonomic control to explain the relationship between baseline and stress responding in SP children and healthy controls (HC), we acquired a broad set of autonomic measures in our study. Method:  To index baseline and stress reactivity and to assess autonomic flexibility, we assessed a comprehensive array of sympathetic and parasympathetic measures in SP children (aged 8 to 12 years; n = 30) and healthy control children (HC, n = 26), while exposing them to the Trier Social Stress Test for Children (TSST-C). Results:  At baseline, the SP children showed higher levels of sympathetic (heart rate, electrodermal activity) and lower levels of parasympathetic (respiratory sinus arrhythmia, RSA) activation when compared to the HC children. During the TSST-C, the SP children showed similar HR responses but a limited RSA reactivity and a slower HR recovery relative to the HC children. Conclusion:  Our study extends previous research by showing elevated baseline arousal and comparable stress responding in SP children relative to HC children. In addition, based on the autonomic flexibility model, we provide a potential explanation for the null findings of previous studies during stress. The pattern of elevated baseline heart rates and reduced RSA point to restricted autonomic flexibility in children with SP.
