是肌肉记忆muscle memory导致了梁彼得无意向地开枪

我开始研究梁彼得案，终于想明白了是什么使梁彼得开枪：肌肉记忆 muscle memory。Wiki词条：

Muscle memory has been used synonymously with motor learning, which is a form of procedural memory that involves consolidating a specific motor task into memory through repetition. When a movement is repeated over time, a long-term muscle memory is created for that task, eventually allowing it to be performed without conscious effort. This process decreases the need for attention and creates maximum efficiency within the motor and memory systems.

就是说这是一种肌肉的程序性记忆，如果一个动作不停地被重复，就会让肌肉形成自己对这个动作的记忆，最终可以让这个动作在没有有意识的努力情况下自动发生。这个程序减低了注意力的需要。比如老是训练射击的动作，精神高度集中于开枪，扣扳机的动作就成了手肌肉的一个记忆，可以在并没有一个人自我意愿的时候因为某种因素刺激激发，而发生。

常有美国警察用这个词作为自己开枪的辩护。最近就是几天前都有一个警察枪击案的报道，那个警察双手持枪，打中了一个骑摩托人的手，警察没被起诉和处罚，它的理由就是他并没有想要开枪，是他一个星期前的训练产生的肌肉记忆导致他扣扳机开枪的。firearm training earlier that month contributed to the unintentional discharge due to the muscle memory of squeezing the trigger.

我想梁彼得也正是在这种情况下开枪的。突然被吓一跳，作为刺激反应，肌肉记忆 导致他无意识地扣动扳机。但是他同时并没有开枪的意向。那时候根本没有思考辨别的时间，就一秒钟之间的事。


Soppeland told investigators that firearm training earlier that month contributed to the unintentional discharge due to the muscle memory of squeezing the trigger.

“My plan was to hold the suspect where he was until back up arrived,” he told investigators three days later. “ … It was not my conscious choice to discharge my firearm. This all happened very fast, maybe within a matter of a second. I could feel the effect of the adrenaline.”
