填空题

In social situations, the classic Intention Movement is "the chair-grasp" Host and guest have been talking for some time, but now the host has an appointment to keep and can get away. His urge to go is held in check by his desire not be rude to his guest.
If he did not care of his guest’s feelings he would simply get up out of his chair and to announce his departure. This is what his body wants to do, therefore his politeness glues his body to the chair and refuses to let him raise. It is at this point that he performs the chair-grasp Intention Movement. He continues to talk to the guest and listen to him, but leans forward and grasps the arms of the chair as about to push himself upwards. This is the first act he would make if he were rising. If he were not hesitating, it would only last a fraction of the second. He would lean, push, rise, and be up.
But now, instead, it lasts much longer. He holds his "readiness-to-rise" post and keeps on holding it. It is as if his body had frozen at the get-ready moment.
