急性应激对大学生认知抑制和 反应抑制的影响.

Objective: To explore the effects of real-life acute stress on cognitive inhibition and response inhibition in college students. Methods: Totally 40 interviewees in the National Postgraduate Entrance Examination were recruited and they were asked to complete the Flanker task and Go/Nogo dual-task immediately after the interview (stress condition) and 7 months after the interview (control condition) respectively. The current stress level was assessed with the Self-reported Stress Scale and State Anxiety Inventory. Results: The self-reported stress scores (P< 0.001), and state anxiety scores (P<0.01) were higher under stress condition than under control condition. In the Flanker task, the reaction time of the incongruent trials was faster under stress condition than under control condition, and the Flanker effect was lower under stress condition than under control condition (Ps <0.05). For the probe stimuli in the Go/Nogo dual task, the reaction time of Nogo-probes and probe Go/Nogo effect was higherunder stress condition than under control condition (Ps <0.05). Conclusion: Acute stress in real life might enhance the cognitive inhibition of distractor but impair the inhibition of incorrect response in college students. [ABSTRACT FROM AUTHOR]
