诱发急性应激对大学生反应抑制的影响.

Objective: To explor the effect of acute stress on response inhibition of college students. Methods: The Trier Social Stress Test was used to evoke the acute stress state of 27 college students（12 males and 15 females）.The neutral state was matched by vocal reading, and the double choice Oddball task was completed under the acute stress and neutral state respectively. Combined with ERP technology, the reaction time, error times,N2 and P3 components were compared. Evaluated the correlation between the offline area of stress area and N2,P3 in the two states. Results: In the double choice Oddball task,compared with the neutral state, the response inhibition time（P <0.05） was shortened, the number of response errors（P <0.05） was reduced, and the amplitudes of N2 and P3 were reduced. Conclusion: Inducing acute stress could promote the response inhibition ability of college students. [ABSTRACT FROM AUTHOR]
