ABSTRACT
Using unipolar shape flow to shrink away from noxious stimuli and grow toward attractive stimuli offers an emotionally-laden mode of response to people and things in the environment. Unipolar shape flow also provides the foundation for a more mature pattern of movement, shaping in directions. While a very young child reaches toward something he wants in the distance, an older child can simply point towards the object. While a young child may shrink away from a bright light, an adult may cross an arm up over her eyes to shield them from the light.
