The effect of fear on attentional processing in a sample of healthy females.

The present experiment examines the effect of fear on efficiency of three attention networks: executive attention, orienting and alerting, in a healthy female sample. International Affective Picture System (IAPS) images were used to elicit both a fear response and a non-emotional response in 100 participants. During the emotion manipulation, participants performed a modified version of the Attention Network Test (ANT). Results showed enhanced executive attention in the fear condition compared to the control condition. Specifically, during a fear experience participants were better able to inhibit irrelevant information resulting in faster response times to a target. There was no effect of fear on orienting while the effect of fear on alerting was inconclusive. It is suggested that enhanced executive attention in fear-eliciting situations may function to focus attention on a potentially threat-related target, thus facilitating subsequent rapid responding.
