According to previous findings (Konttinen and Lyytinen, 1992), the slow brain negativity preceding the trigger pull in rifle-shooting tends to be decreased in successful shots among experienced marksmen, whereas no such pattern is found among inexperienced subjects. This effect was interpreted as resulting mainly from optimal arousal. However, another explanation is examined here. The aim of the experiment was to investigate slow electrocortical changes associated with motor regulation and visual aiming related to shooting performance. Four variations on a shooting task were used, in which the visual and motor components were contrasted. Motor activity related to gun stabilization was found to be associated with slow-wave positivity, whereas visual aiming was manifested as slow negativity. The results offer some basis for interpreting the individual slow brain wave patterns that predict shooting performance.
根据之前的研究结果（孔蒂宁和吕伊蒂宁，1992年），在步枪射击中，扳机扣动前出现的慢脑负波在有经验的神枪手成功射击时往往会减少，而在缺乏经验的受试者中则未发现这种模式。这种效应被解释为主要是由最佳唤醒状态导致的。然而，这里研究了另一种解释。该实验的目的是研究与射击表现相关的运动调节和视觉瞄准所伴随的慢皮层电变化。使用了射击任务的四种变体，其中视觉和运动成分形成对比。发现与枪支稳定相关的运动活动与慢波正波有关，而视觉瞄准则表现为慢负波。这些结果为解释预测射击表现的个体慢脑电波模式提供了一些依据。
