Behavioral and neural stability of attention bias to threat in healthy adolescents
Considerable translational research on anxiety examines attention bias to threat and the efficacy of attention training in reducing symptoms. Imaging research on the stability of brain functions engaged by attention bias tasks could inform such research. Perturbed fronto-amygdala function consistently arises in attention bias research on adolescent anxiety. The current report examines the stabi...

Life-threatening danger and suppression of attention bias to threat.
OBJECTIVE Life-threatening danger is assumed to produce, in tandem, increases in both vigilance toward threat and stress-related symptoms, but no data test the validity of this assumption. The authors examined associations, in real time, among imminent life-threatening danger, stress-related symptoms, and vigilance. METHOD Symptoms of posttraumatic stress disorder (PTSD), depression, and anxi...
متن کاملNeural correlates of attention bias to threat in post-traumatic stress disorder.
Attentional biases have been proposed to contribute to symptom maintenance in posttraumatic stress disorder (PTSD), although the neural correlates of these processes have not been well defined; this was the goal of the present study. We administered an attention bias task, the dot probe, to a sample of 37 (19 control, 18 PTSD+) traumatized African-American adults during fMRI. Compared to contro...
متن کاملModifying Threat-related Interpretive Bias in Adolescents
Socially anxious feelings sharply increase during adolescence and such feelings have been associated with interpretive biases. Studies in adults have shown that interpretive biases can be modified using Cognitive Bias Modification procedures (CBM-I) and subsequent effects on anxiety have been observed. The current study was designed to examine whether the CBM-I procedure has similar effects in ...
