(New) - THE COMPLETE CLARIFICATION OF ALL FUNCTIONAL PERCEPTION PROCESSES WITHIN GRASPING
0. Einstein, the Stationary Coffee Cup, and the Digital Clock: The Visual Perception Observes Stationary Coffee Cups Moving in Time
1. Within the grasping of a coffee cup we always first construct a perceptual image of a latent action trajectory shape out of the perspective of the fingertips – The scientific evidence
2. Grasping requires a compelling collaboration between an internal and an external focus
3. Within grasping the essence of the task is solely executed by the movements of the fingertips toward a coffee cup; Within the primary focus the fingertips are constrained within an action trajectory shape providing the tau-value
4. The tau-coupling process in grasping demonstrates that we absolutely do not need a motor plan
5. Random motor arm activity implicitly induces an internal and an external focus – The scientific evidence how two autonomous foci arise within grasp actions and how their roles evolutionarily have reversed
6. The explanation of the emergence of the cortical streams - We can only guide the fingertips to a coffee cup with a zigzag movement, yet the ingenious mediation by the cortical streams creates the delusion of a straight action trajectory shape
7. Within grasping the cortical streams will have to mediate the egocentric zigzag movement of the fingertips toward the coffee cup
