冲动性攻击行为与抑制控制的核心缺陷有关。冲动性暴力犯的冲动攻击行为最为典型，危害最大，常表现为在愤怒情绪下失去控制。因而，探究冲动性暴力犯在愤怒情绪下抑制控制的加工特点和神经机制具有较大理论价值和现实意义。本项目以冲动性暴力犯为研究对象，匹配冲动性暴力犯和对照组的特质愤怒水平，采用改编版双选择Oddball范式、事件相关电位和功能性近红外光学成像手段，对比冲动性暴力犯和对照组抑制控制的差异（横向对比），对比两组在愤怒情绪激发前后抑制控制变化的差异（纵向比较），揭示冲动性暴力犯抑制控制的特点和愤怒情绪激发前后抑制控制变化的特点及其神经机制，为冲动性暴力犯心理矫治实践提供实证支持。

Impulsive aggression is related to the core deficit of inhibition control. Impulsive violent offenders have the most typical impulsively aggressive behaviors, which are the most harmful. They often lose control of themselves in anger. Therefore, it is of great theoretical value and practical significance to explore the processing characteristics and neural mechanism of impulsive violent criminals' inhibition control in anger. Impulsive violent offenders are selected and matched with control groups in levels of trait anger. The adaptation of double selection of Oddball paradigm, event related potential and functional near infrared optical imaging method are adopted. We plan to compare the differences in inhibitory control between impulsive violent offenders and the control groups (horizontal aspect), and contrast differences in inhibition control changes before and after anger emotional arousal between the two groups (longitudinal aspect). The research results will reveal the characteristics and neural mechanism of inhibition control and its changes in anger arousal for impulsive violent offenders. This will provide empirical support in psychological treatment practice for impulsive violent offenders.
