    Attention has been found to favor threat in various anxiety disorders. Obsessive-compulsive disorder is characterized by anxious responding to threatening stimuli. OCD includes obsessions and/or compulsions aimed at preventing or reducing distress or preventing dreaded events. However, research has shown inconsistent results regarding the presence of attentional bias in obsessive-compulsive disorder. The aim of this study was to examine attentional bias towards contaminating and disgusting images, using an attentional blink paradigm in a sample of university students high (HCF; n=17) or low (LCF; n=15) in contamination fear. The accuracy in performance of these groups was compared across neutral-, generally threatening, contamination- and disgust-related images that were followed by discrimination task 200, 500 or 800 ms later in a row of images. This provides a measure of the ability of emotional task-irrelevant stimuli to capture attention. It was expected that HCF but not LCF participants, would demonstrate attentional bias towards disgust- and contamination-related images, particularly at shorter task presentations. Results showed lower accuracy in the HCF compared to the LCF group after presentation of disgusting images at lag 2, consistent with the literature on the attentional blink. The HCF group had lower overall accuracy on the attentional blink task. Increase in negative affect was observed in the HCF but not the LCF group and this was related to scores on contamination fear questionnaire. Decreased positive affect was observed in both groups. Results indicate delayed disengagement in individuals with contamination fear that is particularly pronounced with disgust related stimuli at automatic stages of information processing.
