Recent research has demonstrated a counterproductive attentional bias toward threat-related stimuli: under conditions in which fixating on a color distractor stimulus sometimes resulted in an immediate shock, participants were nevertheless more likely to look at this threat-related distractor than a neutral distractor matched for physical salience. However, participants in that prior research may not have realized that their own actions caused delivery of aversive outcomes, such that monitoring for the threat-related distractor may not have been counterproductive from participants' perspective. In Experiment 1 of the current study, we demonstrate that the attentional bias to the threat-related distractor persists (and indeed, becomes stronger) when participants are made explicitly aware that looking at this stimulus is the sole cause of aversive events, which are otherwise avoidable. In Experiment 2 we replicate the bias in informed participants under conditions in which there is additional (reward-driven) motivation to avoid attending to distractors. Taken together with prior findings, the observation of an attentional bias toward the threat-related distractor under these explicitly counterproductive conditions provides strong support for the idea that threat-related stimuli are automatically prioritized by our attentional system.

Anxiety can impair the central executive functioning in working memory (WM). Further, the adverse effect of anxiety on the central executive would be greater when threat-related distractors are present. This study investigated the effect of task-irrelevant emotional faces on WM updating in social anxiety.

Elevated arousal in anxiety is thought to affect attention control. To test this, we designed a visual short-term memory (VSTM) task to examine distractor suppression during periods of threat and no-threat. We hypothesized that threat would impair performance when subjects had to filter out large numbers of distractors.

The present study aimed to determine whether persistent threat-related attentional capture can result from instructional learning, when participants acquire knowledge of the aversive qualities of a stimulus through verbal instruction. Fifty-four nonclinical adults first performed a visual search task in which a green or red circle was presented as a target. They were instructed that one of these two colors might be paired with an electric shock if they responded slowly or inaccurately, whereas the other color was never associated with shock.

Behavioral evidence shows that individuals with high trait anxiety tend to be distracted by irrelevant stimulation not only for threat-related stimuli but also for non-emotional neutral stimuli. These findings suggest that there may be a general deficit of attentional control in trait anxiety. However, the neural mechanism underlying the anxiety-related deficit in attentional control, especially inhibition function, is still unclear.
