Behavioural Optometry
Visual Spatial Organisation
Each individual projects their internal understanding (termed body spatial scheme or body map) of orientation, sidedness and direction out into space to create a personal visual space, a map-like representation or understanding of what is 'out there' based upon his own unique experience of the world.
This continuously developing three-dimensional map enables him to navigate his way through space, to understand where he is relative to the world, where objects are relative to himself and to each other. Feedback from other senses help him refine his space world so that it matches with reality, so that it becomes a true representation of what is actually "out there".
Through this process vision is no longer segmented, with isolated objects suspended somewhere in space, without proper interrelation of objects to their component parts and other objects, self and the environment, i.e. without context.
Once we know where we are and where our parts in space we can then select an area of space (or a visualized representation if we are thinking) for our attention and direct our actions to that specific point.
