Learning better control

In the vector representation of the perceptual function and the influences of the output signal in the Outer World, the appropriateness of the control action is represented by the relative orientations of the two vectors. The closer the orientation, the fewer side-effects and the more of the output energy is going into controlling the perception. In this representation, "learning" consists of bringing the vectors representing the perceptual function and the output influences into closer alignment. This could be done by changing the orientation of either. Reorganization could involve learning to perceive something differently, learning to act differently to control a given perceptual signal, or both. (It can also involve other alterations to the structure of the hierarchy, but we are not considering those possibilities here.)
