Anxiety disorders are the most frequently diagnosed form of psychopathology in children and often result in chronic impairment that persists into adulthood. Identifying neurobehavioral correlates of anxiety that appear relatively early in life would inform etiological models of development and allow intervention and prevention strategies to be implemented more effectively. The error-related negativity (ERN), a negative deflection in the event-related potential at fronto-central sites approximate...

The anxiety disorders have the highest prevalence of any group of psychiatric disorders (Kessler et al., 2005). Considering the early onset, chronic course (Bittner et al., 2007; Yonkers, Bruce, Dyck, & Keller, 2003), associated functional impairment, and high economic costs of anxiety disorders (Kessler & Greenberg, 2002), there is a critical need to discover pathophysiological markers and identify persons at risk for these conditions. There is growing evidence that abnormal error-related brain...

The dopamine active transporter 1 ( DAT1 ) gene is implicated in psychopathology risk. Although the processes by which this gene exerts its effects on risk are poorly understood, a small body of research suggests that the DAT1 gene influences early emerging negative emotionality, a marker of children's psychopathology risk. As child negative emotionality evokes negative parenting practices, the DAT1 gene may also play a role in gene–environment correlations. To test this model, children ( N = 36...

Background: A growing literature indicates that the Child Behavior Checklist-Dysregulation Profile (CBCL-DP) identifies youths with heightened risk for severe psychopathology, comorbidity, and impairment. However, this work has focused on school-age children and adolescents; no studies have examined whether preschool-aged children with the CBCL-DP exhibit a similar constellation of problems. Method: Using a community sample of preschoolers, we compared children with (N = 61) and without (N = 488...

The current study examined behavioral measures and response-locked event-related brain potentials (ERPs) derived from a Go/No-Go task in a large (N = 328) sample of 5- to 7-year-olds in order to better understand the early development of response monitoring and the impact of child age and sex. In particular, the error-related negativity (ERN, defined on both error trials alone and the difference between error and correct trials, or ΔERN), correct response negativity (CRN), and error positivity (...

Background—The late positive potential (LPP) is an event-related potential component that indexes selective attention toward motivationally salient information and is sensitive to emotional stimuli. Few studies have examined the LPP in children. Depression has been associated with reduced reactivity to negative and positive emotional stimuli, including reduced LPPs in response to emotional faces. The current study sought to identify the time course and scalp distribution of the LPP in response t...

We examined the psychometric properties of the Behavioral Inhibition Questionnaire (BIQ; Bishop, Spence, & McDonald, 2003), a rating scale for children's behavioral inhibition. Parent and teacher ratings, parent interviews, and laboratory observations were obtained for 495 preschoolers. Confirmatory factor analysis yielded 6 factors, each reflecting the BIQ's subscales, and all loading onto a second-order general dimension. Model fit was acceptable for parent ratings, but only marginal for teach...

Attentional biases for negative stimuli have been observed in school-age and adolescent children of depressed mothers and may reflect a vulnerability to depression. The direction of these biases and whether they can be identified in early childhood remains unclear. The current study examined attentional biases in 5–7-year-old children of depressed and non-depressed mothers. Following a mood induction, children participated in a dot-probe task assessing biases for sad and happy faces. There was a...
