我開始研究梁彼得案,終於想明白了是什麼使梁彼得開槍:肌肉記憶 muscle memory。Wiki詞條:
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.
就是說這是一種肌肉的程序性記憶,如果一個動作不停地被重複,就會讓肌肉形成自己對這個動作的記憶,最終可以讓這個動作在沒有有意識的努力情況下自動發生。這個程序減低了注意力的需要。比如老是訓練射擊的動作,精神高度集中於開槍,扣扳機的動作就成了手肌肉的一個記憶,可以在並沒有一個人自我意願的時候因為某種因素刺激激發,而發生。
常有美國警察用這個詞作為自己開槍的辯護。最近就是幾天前都有一個警察槍擊案的報道,那個警察雙手持槍,打中了一個騎摩託人的手,警察沒被起訴和處罰,它的理由就是他並沒有想要開槍,是他一個星期前的訓練產生的肌肉記憶導致他扣扳機開槍的。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這種情況下開槍的。突然被嚇一跳,作為刺激反應,肌肉記憶 導致他無意識地扣動扳機。但是他同時並沒有開槍的意向。那時候根本沒有思考辨別的時間,就一秒鐘之間的事。
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.」
