Indeed, Peon.
And I have a slight disagreement with Moxie's statement. While, yes, it is true that those in pursuit of phenomenon tend to visualize what other do not the action is not a direct result of simply "looking for it". The human mind, no matter how intellectual that individual may be, is capable of determining an object in the midst of chaos. In short, ones perspective plays a significant role in determining colors, shapes and so on.
