AbstractThis study examined the effect of Cognitive Bias Modification (CBM) in college students with elevated anxiety. Participants completed a CBM training task, designed to measure and manipulate attentional biases, and were then subjected to an insoluble anagram stressor. Electrocardiogram (EKG) data was recorded first before training and then following the stressor; respiratory sinus arrhythmia (RSA), an indicator of vagal tone, was extracted from the EKG data. With a sample size of 40 participants, no between-groups difference was found in mood state or RSA; however a correlation was found between RSA and the positive component of affect (R=0.336).
