Hyperactivity
It takes all kinds of forms and makes us see all kinds of things. Let us come back to the well known fact that equilibrium resides at the level of the semi-circular canals inside the inner ear. Their function will be adequate only if one can count on a physical stability to find one's centre there, essential reference point to be able to organize there the surrounding space.
The curve representative of hyperactivity is characterized by a perception that alternates from one ear to the other. Our subject then always feels a need to correct his posture to reestablish this too precarious equilibrium. He moves and talks non-stop. It is true that these symptoms can manifest with persons so called "nervous". It will then be pertinent to make an evaluation with the central listening test, because it is detectable by its zigzag curve, as it is easy to see on this example.
Compare this curve with the ideal curve.
