Attention Training for Childhood Obsessive Compulsive Disorder

"Each trial begins with a fixation cross presented in the center of the computer screen for 500 ms. The cross is then replaced by a word pair presented in the center of the screen for 500 ms. The word pair disappears and a probe (i.e., the letter E or F) appears immediately in the location of one of the two words. Participants will be instructed to decide whether the letter is an E or an F and press the corresponding mouse button. This paradigm has been modified to facilitate an attention bias away from threatening material. In this case, the probe always replaces the neutral word. Thus, although there will be no specific instruction to direct attention away from the threat word, on all trials, the position of the neutral word will indicate the position of the probe."
