The ability to regulate emotions is an important part of adaptive functioning in society. Advances in cognitive and affective neuroscience and biological psychiatry have facilitated examination of neural systems that may be important for emotion regulation. In this critical review we first develop a neural model of emotion regulation that includes neural(More)
In this study we examined the development of three action monitoring event-related potentials (ERPs) - the error-related negativity (ERN/Ne), error positivity (P(E)) and the N2 - and estimated their neural sources. These ERPs were recorded during a flanker task in the following groups: early adolescents (mean age = 12 years), late adolescents (mean age = 16(More)
BACKGROUND Although reward processing is considered an important part of affective functioning, few studies have investigated reward-related decisions or responses in young people with affective disorders. Depression is postulated to involve decreased activity in reward-related affective systems. METHODS Using functional magnetic resonance imaging (fMRI),(More)
This study investigated pupillary and behavioral responses to an emotional word valence identification paradigm among 32 pre-/early pubertal and 34 mid-/late pubertal typically developing children and adolescents. Participants were asked to identify the valence of positive, negative, and neutral words while pupil dilation was assessed using an eyetracker.(More)
BACKGROUND In this study we used event-related potentials (ERPs) and source localization analyses to track the time course of neural activity underlying response monitoring in children diagnosed with an anxiety disorder compared to age-matched low-risk normal controls. METHODS High-density ERPs were examined following errors on a flanker task from 12(More)
BACKGROUND This study investigated whether processing emotionally salient information such as emotional facial expressions influences the performance on a cognitive control task in pediatric anxiety and depression. METHODS The sample included 68 participants between 8 and 16 years of age selected into three diagnostic groups: Anxiety Disorder (ANX, n =(More)
The goal of this study was to examine some of the mechanisms underlying emotion regulation in childhood affective disorders by examining the impact of distracting emotional information during performance on a working memory task ("Emotional n-back" or E-n-back). The sample included 75 children (38 girls and 37 boys) between 8 and 16 years of age meeting(More)
OBJECTIVE To examine abnormal patterns of frontal cortical-subcortical activity in response to emotional stimuli in euthymic individuals with bipolar disorder type I in order to identify trait-like, pathophysiologic mechanisms of the disorder. We examined potential confounding effects of total psychotropic medication load and illness variables upon neural(More)
This study examined the effects of trait anxiety and age on performance of an emotional working memory task designed to investigate attentional control processes in the context of emotion. Participants included children, adolescents, and adults (8-30 years old). They performed the Emotional Face N-Back (EFNBACK) task, a modified n-back working memory task(More)
OBJECTIVE To study white matter (WM) development in youth at high familial risk for bipolar disorder (BD). WM alterations are reported in youth and adults with BD. WM undergoes important maturational changes in adolescence. Age-related changes in WM microstructure using diffusion tensor imaging with tract-based spatial statistics in healthy offspring having(More)
