Although it is well established that response inhibition to angry expressions is impaired among reactively aggressive adolescents, the cognitive processes underlying this effect remain unclear. The main goal of our study was to investigate the time course of response inhibition to angry expressions in reactively aggressive adolescents compared to controls. In total, 23 reactively aggressive adolescents and 23 control adolescents were recruited to participate in an event-related potential (ERP) study measuring response inhibition to angry expressions with an emotional Go/No-go paradigm. The results showed that when presented angry or happy expressions, reactively aggressive adolescents showed a smaller No-go P3 effect than the control group. These results indicate that response inhibition to angry expressions in reactively aggressive adolescents is impaired at the later stage of the actual inhibitory control. The characteristics of response inhibition to happy expressions in reactively aggressive adolescents are similar to those in response to angry expressions.
尽管已有充分证据表明，反应性攻击型青少年对愤怒表情的反应抑制存在受损情况，但这种效应背后的认知过程仍不清楚。我们研究的主要目的是调查与对照组相比，反应性攻击型青少年对愤怒表情的反应抑制的时间进程。总共招募了23名反应性攻击型青少年和23名对照青少年，参与一项采用情绪Go/No-go范式测量对愤怒表情反应抑制的事件相关电位（ERP）研究。结果表明，当呈现愤怒或高兴表情时，反应性攻击型青少年的No-go P3效应比对照组小。这些结果表明，反应性攻击型青少年对愤怒表情的反应抑制在实际抑制控制的后期阶段受损。反应性攻击型青少年对高兴表情的反应抑制特征与对愤怒表情的反应抑制特征相似。
