Which reflex is triggered when a stranger suddenly grasps your arm?

Crossed-Extensor Reflex

When you are startled by the sudden contact, your arm is pulled into a guarding position. When the person releases your arm, a number of movements take place. The extensor muscles contract in order to overcome gravity and pull your arm back to it’s starting point. 

This reflex was first discovered in 1993 by Dr. Louis Rosenberg who noticed that the reflex seemed to be more prevalent in children than adults (only around forty percent return their arms). The crossed extensor reflex can also occur when you grab something awkwardly or when you are forced to sit down really quickly and bounce off the seat. It is harder to do when you are kneeling and when you are standing.
