Suppose you are in a snowstorm and can tell which way the wind is blowing by what percentage of snowflakes are moving in the same direction. What type of motion perception is this most analogous to?

Correlated-dot motion

Explanation:

Motion perception is a process of inferring the direction of elements and the speed of the motion during a scene which is based on the visual or vestibular or proprioceptive inputs.

In the context, inferring the motion in a snowstorm by seeing which way the wind is blowing and by what percentage of the snowflakes are been moving in same direction is analogous to the correlated dot motion.
