In this issue of the Journal, Eldar et al. (10) report the first randomized controlled trial to evaluate whether computerized attention bias modification can ameliorate the symptoms of pediatric clinical anxiety. Forty children with a current anxiety disorder (separation anxiety disorder, generalized anxiety disorder, specific phobia, or social phobia) were randomly assigned to one of three conditions. In the attention bias modification condition, children completed a version of the computerized probe task designed to train attentional bias away from threatening stimuli. On each trial, a fixation cross was followed by two photographs (an angry face and a neutral face) exposed for 500 msec. Immediately the photographs disappeared; a small probe was presented in the screen location where one of the two images had just been shown. This probe was a pair of dots aligned either horizontally or vertically, and the child's job was simply to press a button to indicate which type of probe appeared. In the condition designed to induce attentional bias away from the more threatening stimulus, probes always appeared distal to the location where the angry face had just been shown and proximal to the location where the neutral face had been shown. Numerous such trials (1,920 in total) were completed over four weekly sessions.
