The analysis of spatial behavior is, fundamentally, a description of the way behavior is conditioned by internal and external constraints. Skews of spatial orientation are brought about by visual adaptation to these two constraints. The Van Orden Star probes the way we perceive, and mentally represent, the world around us. The Star can give insight into how we put this knowledge to work, and into action. 1
In every day life, we see coping patterns people have adopted in response to what they see and feel. There may be a turned foot, or a curved back; there may be heightened or lessened attention to a task. Coping patterns sometimes generate labels: dyslexic, autistic, emotionally disturbed, brain injured.
Perceptual far-or near-point activities involve different levels of constraints. How an individual responds to these constraints is manifested in the way he modifies his drawing of the Van Orden Star patterns......
