Cognitive neuroscientists believe that the visual system is a dual-processing system in which a visual perception track enables us "to think about the world"—to recognize things and to plan future actions.
When we are using the visual perception track, we are visualizing and interpreting the world around us. Visualizing is taking something we see or hear into our heads and putting it the way we want to see it. Perception is how we see something to be and everyone's perception is different.
