冲动性暴力犯愤怒条件下的阈上阈下反应抑制受损

Impairment in Conscious and Unconscious Response Inhibitions of Impulsive Violent Offenders on the Angry Condition

本研究使用情绪性Go/No-go任务(实验1)和掩蔽版Go/No-go任务(实验2),考察暴力犯和对照组在中性条件和愤怒条件下的阈上阈下反应抑制能力。实验1发现,相比中性条件下,暴力犯和对照组在愤怒条件下Go反应时更短,No-go错误率更高;愤怒条件下暴力犯比对照组Go反应时更短,No-go错误率更高。实验2发现,相比中性条件下,在愤怒条件下暴力犯No-go反应时和RT-slowing更短,而对照组无显著差异;在愤怒条件下,暴力犯比对照组No-go反应时和RT-slowing更短。结果表明,相比中性条件下,愤怒条件下暴力犯呈现阈上阈下反应抑制受损;愤怒条件下,暴力犯比对照组阈上阈下反应抑制表现差。

The present study utilized an emotional Go/No-go task(Experiment 1)and a masked Go/No-go task(Experiment 2)to examine the conscious and unconscious response inhibition abilities of violent offenders and a control group with neutral and angry emotional conditions.In Experiment 1,we found that both the control group and violent offenders had shorter Go reaction times and higher Nogo error rates with the angry condition compared to the neutral condition.We also found that with the angry condition,violent offenders had even shorter Go reaction times and higher No-go error rates than the control group.In Experiment 2,the results showed that compared to the neutral condition,violent offenders had shorter No-go reaction times and RT-slowing on the angry condition,while no such significant differences were observed in the control group.Violent offenders had shorter No-go reaction times and RT-slowing under the angry condition compared to the control group.The results indicate that,compared to the neutral condition,violent offenders exhibit impaired conscious and unconscious response inhibitions on the angry condition.Additionally,the performance of violent offenders in conscious and unconscious response inhibitions are worse on the angry condition than that of the control group.
