The goal of this study was to examine behavioral and electrophysiological correlates of involuntary orienting toward rapidly presented angry faces in non-anxious, healthy adults using a dot-probe task in conjunction with high-density event-related potentials and a distributed source localization technique. Consistent with previous studies, participants(More)
BACKGROUND Previous studies investigating attentional biases in social anxiety disorder (SAD) have yielded mixed results. Recent event-related potential (ERP) studies using the dot-probe paradigm in non-anxious participants have shown that the P1 component is sensitive to visuospatial attention towards emotional faces. We used a dot-probe task in(More)
OBJECTIVE The evidence for the efficacy of D-cycloserine (DCS) for augmenting cognitive behavioral therapy (CBT) for anxiety disorders has been mixed. Guided by preclinical research and initial findings from a small-scale study involving humans, we tested the hypothesis that DCS enhancement of exposure therapy would be specific to successful exposure(More)
OBJECTIVE The aim of the current study was to identify individual characteristics that (a) predict symptom improvement with group cognitive behavioral therapy (CBT) for social anxiety disorder (SAD; i.e., prognostic variables) or (b) moderate the effects of d-cycloserine (DCS) versus placebo augmentation of CBT for SAD (i.e., prescriptive variables).

Earlier research found autonomic and airway reactivity in asthma patients when they were exposed to blood-injection-injury (BII) stimuli. We studied oscillatory resistance (R(os)) in asthma and BII phobia during emotional and disease-relevant films and examined whether muscle tension counteracts emotion-induced airway constriction. Fifteen asthma patients,(More)
CONTEXT Social anxiety disorder (SAD) is common and debilitating. Although exposure therapy is one of the most effective forms of psychotherapy for this disorder, many patients remain symptomatic. Fear reduction in exposure therapy is similar to extinction learning, and early clinical data with specific phobias suggest that the treatment effects of exposure(More)
Cognitive-behavioral therapy (CBT) and pharmacotherapy are similarly effective for treating panic disorder with mild or no agoraphobia, but little is known about the mechanism through which these treatments work. The present study examined some of the criteria for cognitive mediation of treatment change in CBT alone, imipramine alone, CBT plus imipramine,(More)
Stressed and tense individuals often are recommended to change the way they breathe. However, psychophysiological effects of breathing instructions on respiration are rarely measured. We tested the immediate effects of short and simple breathing instructions in 13 people seeking treatment for panic disorder, 15 people complaining of daily tension, and 15(More)
People exposed to high altitudes often experience somatic symptoms triggered by hypoxia, such as breathlessness, palpitations, dizziness, headache, and insomnia. Most of the symptoms are identical to those reported in panic attacks or severe anxiety. Potential causal links between adaptation to altitude and anxiety are apparent in all three leading models(More)
OBJECTIVE The authors examined whether D-cycloserine, a partial agonist at the glutamatergic N-methyl-d-aspartate receptor, augments and accelerates a full course of comprehensive cognitive-behavioral therapy (CBT) in adults with generalized social anxiety disorder. METHOD This was a multisite randomized placebo-controlled efficacy study with 169(More)
