(New) - THE COMPLETE CLARIFICATION OF ALL FUNCTIONAL PERCEPTION PROCESSES WITHIN LETTER POSTING
0. Einstein, the Stationary Mailbox, and the Digital Clock: The Visual Perception Observes Stationary Mailboxes Moving in Time
1. Prior to posting a letter we always first construct a perceptual image of a latent action trajectory shape out of the perspective of the letter – The scientific evidence
2. Posting a letter demands a compelling cooperation between an internal (secondary) focus and an external (primary) focus – Solely the movements of the letter constitute the primary focus
3. Within letter posting the essence of the task is solely carried out by the movements of the letter; Within the primary focus the letter moves like a marble in a marble run producing the tau-value
4. Executing an external action trajectory shape along which the letter moves dictates all internal sensorimotor perception processes; The tau-coupling process when posting a letter demonstrates that we absolutely do not need a motor plan
5. The letter isn’t capable to move by itself along an action trajectory shape; Scientific evidence of the implicit occurrence of an internal and external focus during random motor activity and how their roles evolutionary have reversed within letter posting
6. The explanation of the emergence of the cortical streams - We can only guide the letter to a mail box with a zigzag movement, yet the ingenious mediation by the cortical streams creates the delusion of a straight action trajectory shape
