Taking the example of an SLE looking at a child's drawing of a soccer ball on a soccer field, the circle is first perceived by Se, which registers an impression of a rounded line which connects back upon itself. Ti then takes that impression, and categorizes it as "a circle". Ne then considers the possibilities of what that circle might represent: "a sphere? a cylinder?" This range of possibilities is passed along to Fi, which tries to narrow it down: "cylinders don't belong on soccer fields, so it must be a sphere". This information may be passed along again to Se, and the cycle begins again. All of this, of course, happens in fractions of a second.
In the case of an actual soccer ball on an actual field, due to the subject's binocular vision,
his Se directly receives the impression that this is a round object, his Ti categorizes it as "sphere" or "ball", and his Ne begins to consider what sort of ball it might be. As you can see, the process is much quicker and more direct with a real-world object; this is one reason why Se types prefer to live in "the real world" instead of the pictures and words and other symbolic "worlds" that Intuitive types enjoy -- processing what something "might be" is difficult and time consuming and "backwards" for them. An Ne type would have a much easier time of it.
