Reports of exaggerated anxiety and physiological hyperreactivity to social-evaluative situations are characteristic of childhood social phobia (SP). However, laboratory research on subjective, autonomic and endocrine functioning in childhood SP is scarce, inconsistent and limited by small sample sizes, limited breadth of measurements, and the use of(More)
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(More)
BACKGROUND AND OBJECTIVES Attentional bias towards threat in socially anxious adults is well documented; however, research on this bias in children with social phobia is rather scarce. The present study investigates whether the hypervigilance-avoidance hypothesis also applies to children with social phobia. METHODS Thirty children (aged 8-12) with social(More)
In the aftermath of a distressing social event, adults with social phobia (SP) engage in a review of this event with a focus on its negative aspects. To date, little is known about this post-event processing (PEP) and its relationship with perceived performance in SP children. We measured PEP in SP children (n=24) and healthy controls (HC; n=22), aged from(More)
Cognitive models of social phobia (SP) and empirical evidence in adults suggest that affected individuals overestimate arousal symptoms such as heart rate (HR) during social stress and worry about their visibility in public. To date, little is known about these aspects in childhood social anxiety, an important precursor of the disorder. We assessed(More)
Cognitive models of social phobia (SP) assume that following social evaluative stress, individuals with SP engage into dysfunctional post-event processing (PEP), a detailed negative review of the past event. While previous research has already shown, that children with high levels of social fears suffer from more frequent negative PEP, it remains unclear(More)
BACKGROUND Social anxiety is thought to be strongly related to maladaptive emotion regulation (ER). As social anxiety symptoms accumulate in families, we hypothesize that maladaptive ER is also more prevalent in families with anxious children. Thus, we analyze differences in emotion regulation of both child and mother in relation to social anxiety, as well(More)
The symptoms experienced by patients with agoraphobia are often attributed to excessive autonomic arousal, but recent theories postulate blunted rather than enhanced autonomic reactivity. Cognitive models explain this contrast by distorted interoception, possibly linked to dysfunctional emotion regulation under stress. In the current study, physiological(More)
IAGOS (In-service Aircraft for a Global Observing System) performs long-term routine in situ observations of atmospheric chemical composition (O3, CO, NOx, NOy, CO2, CH4), water vapour, aerosols, clouds, and temperature on a global scale by operating compact instruments on board of passenger aircraft. The unique characteristics of the IAGOS data set(More)
Die Schmauchspurenanalytik ist ein wichtiges Element kriminaltechnischer Untersuchungen zur Aufklärung von Schussdelikten. Schmauchspuren werden an Menschen und Objekten nachgewiesen, die sich in direkter Umgebung des abgegebenen Schusses befanden. Analysis of gunshot residues is an important forensic tool in the clearance of gun crimes. Gunshot residues(More)
