The present study to explore the inhibition function in selective attention of anxious individuals, by using the modified negative affective priming paradigm, the event-related potential technology and threat and neutral words as stimulus material.20 undergraduates selected by State-Trait Anxiety Inventory were divided into high and low trait anxious groups and participated present experiment voluntarily.Results indicated: Under the condition of negative priming, reaction times (RT) of low anxious individuals were significantly slower than the control condition, for threat and neutral targets; for high anxious individuals, RT under the condition of negative priming were significantly faster than the control condition; Induced P2 amplitude for the negative priming conditions was significantly attenuation than the control condition in high anxious group, while it was just the opposite for low anxious individuals; there was no different between induced LPC amplitude for the negative priming conditions and the control condition in high and low anxious group.Conclusion: High trait anxious undergraduates had deficits in effective inhibition distracting information.
