Psychomotor Excitement: or Behavioral Excitement, refers to a large increase in movements and behaviors. If this increase is in harmony with the thoughts and feelings of the moment, and at the same time the movements of the parts of the body are coordinated, it is called coordinated excitement. Excitement during emotional excitement and excitement during light mania fall into this category.
