在本研究中，注意冲动和非计划冲动与身体攻击呈正相关，与阅读水平呈负相关，与古怪的连续操作任务(CPT)诱发的事件相关电位顶区P300的波幅呈负相关。相反，运动冲动被发现与攻击性或阅读水平无关，但有趣的是，它被发现与古怪任务中顶区P300的幅度呈正相关。此外，身体攻击和言语攻击与阅读水平呈负相关，而愤怒和敌意与阅读水平无关。身体攻击和言语攻击在古怪任务中与中央和顶区P300的波幅呈负相关，但在CPT任务中与P300的波幅无关。此外，敌意与CPT中枢区P300波幅呈负相关，而与古怪任务中P300波幅无显著相关。在任何区域或任务中，愤怒与P300的波幅均无显著关系。阅读水平除与冲动、攻击性这些亚特质呈负相关外，还与P300波幅呈正相关。根据艾森克的冲动性理论对这些结果进行了讨论。(C)1997年爱思唯尔科学有限公司。
In the present research, attentional impulsiveness and non-planning impulsiveness were found to relate positively with physical aggression, negatively with reading level, and negatively with the amplitude of the parietal-region P300 of the event-related potential evoked in an oddball and continuous performance task (CPT). In contrast, motor impulsiveness was found not to relate to aggression or reading level, but, interestingly, it was found to relate positively to amplitude of the parietal-region P300 in the oddball task. Additionally, physical and verbal aggression related negatively to reading level, whereas anger and hostility did not. Physical and verbal aggression also related negatively to the amplitude of the central- and parietal-region P300s in the oddball task but not in the CPT. Moreover, hostility related negatively to the amplitude of the central-region P300 in the CPT, but did not relate significantly to the P300 amplitude in the oddball task. Anger showed no significant relations with the amplitude of the P300 in any region or task. In addition to reading level relating negatively with these subtraits of impulsiveness and aggression, it related positively with the amplitude of P300. These results are discussed in terms of Eysenck's theory of impulsiveness. (C) 1997 Elsevier Science Ltd.
