We also indicate how fast we are moving(optic flow) Motion also helps us to perceived movement and avoid dangerous. Just from the movement we can indicate the situation or emotions. situations. Akinetopsia/agnosia=inability to judge or detect the motions and become inable to interpret what actually happen: attracting attention: Motion is a primary mean of attracting attention. Predator using movement to prey. as a primary mean to locate. If the prey remain motionless, it is less likely to be noticed. In human, if you see an object is moving fast. You will try to avoid hitting by it: information about the object: Motion would also help us to identify the shape of the object. Moving different angle we can get a full perception of an object. Prey will hold still if they want to avoid being detected. Illusory motion: motions produced by stimuli that are not actually moving.
