儿童期虐待对抑制控制功能的影响及其脑机制

The Effect of Childhood Maltreatment on Inhibitory Control and Its Neural Mechanism

抑制控制功能(Inhibitory Control)是指个体有目的、主动的排除或减少无关信息干扰,抑制优势思维或反应的能力,包含通达、删除和压抑三个重要组成部分。儿童期受虐待的个体易对干扰信息进行加工,不能有效地删除当前无关信息和抑制优势反应。儿童期虐待也损害大脑的前扣带回皮层、额下回和颞叶等区域的成熟和联结,同时这些脑区是抑制控制功能发展的重要神经生理基础。未来研究应注重情绪和精神障碍对受虐待个体抑制能力的影响,以及通过抑制控制训练,减少受虐待个体的不良行为。

Inhibitory control, an individual＇ s ability to exclude or reduce irrelevant information interference, and inhibit advantage thinking or responses, includes such integral parts as access, deletion, and restraint. Individuals with a history of childhood maltreatment tend to process interference information, and cannot remove the irrelevant information or inhibit the advantage response. Furthermore, childhood maltreatment impairs the associ- ation between the anterior cingulate cortex, the frontal gyms, and the temporal lobe, which are important neural basis for the control of inhibitory functions. Future research is expected to pay attention to the effects of emotions and mental disorders on maltreated children, and reduce their poor performance by means of the training related to the control of inhibitory functions.
